My grandfather, Victor Horton, flew the YF-12A during his NASA career. It was a missile-armed, 2-seat interceptor version of the A-12. He said it was a better plane than the more famous SR-71A, which he also flew. Three were built, but Grandpa's YF-12, 60-6935, is the only one left; 6934 and 6936 were lost to accidents, although the salvageable back half of 6936 was combined with the forward fuselage from an SR-71A static test article to create the "SR-71C" (affectionately dubbed "The Bastard" by flight crews). Grandpa flew that one as well and said it never handled quite right, so was retired after only a few years.
After being wounded in Nam and months in an Army hospital in Japan, I was assigned to Okinawa. Our Army Ordinance Company was next to Marine Camp Schwab in Nago District where the "Ospreys" are being relocated. I was there June 67' to March 68'. I think it was late 67' that I saw the Blackbird at about 12-15,000' cutting a large arc and losing altitude for Kadena to our south. Being around planes most of my life I could not identify it and asked another troop what it was. He simply said "Blackbird". I would on occasion see them and witnessed a takeoff from Kadena while on a supply truck run to one of our dumps next to Kadena. I also parked at the end of the runway to watch 52's labor off the runway and immediately rendezvous with KC-135's to top off for the Nam run. 60'000lbs of bombs of different sizes for different missions. In Nov 66' I was a rifleman with A 2/27, 25th Div in a rain forest not far from the Cambodian border in 3rd Corps. Three 52's in formation, each with 30 2'000lb bombs hit an area where a NVA regiment from the 324B Division was thought to have regrouped after kicking our ass the week before. We were 2+ miles from the strike. I saw the 52's thru a break in the canopy by sure luck. I looked up because I heard a "hissing" sound" which turned out to be the bombs falling. All hell broke loose as the earth shook under our feet and things fell from the big trees. The next morning we took my company to sweep the strike Zone. You could drop a house into each of those 90 craters. Each bomb shattered a football field size clearing. We found collapsed bunkers and much blood in the area. What was left of them went over into Cambodia and we went back to Cu Chi for Thanksgiving. Sorry, I got carried away with memories.
Thank you for your sacrifice and service sir. Being on the ground in Nam was 1,000 times more intense than being in the air. Not trying to diminish what the airmen were up against, but trudging through the Vietnam rainforest with all that gear not knowing when the next ambush would happen must have been nerve racking! 😳

Don't worry about Russia - they were handsomely rewarded when Obama and Hillary sold them 20% of our Uranium reserves. Compare the cost of acquiring Uranium vs Titanium and you will see that Russia made out when you compare the two exchanges of rare elements.
@JOE BLOW FROM COCOMO please check your info, the Uranium One deal was for a Russian energy company to buy a Canadian energy company that operated uranium mining operations in the US but did not involve any exporting of uranium. Did the Clintons receive payments to help make the deal happen? Probably, they are as corrupt as any other politicians. Does this excuse any actions done by others in the government? Nope.
Interesting fact: SR-71 was actually tasked to do the opposite of being stealthy sometimes. During one operation Maj Brian Shul (author of sled driver) was flying the blackbird and was told to take up a racetrack pattern just over the building in which many leaders of non friendly countries were having a meeting. The idea being they could hear the distinctive double sonic boom ever few minutes and would know the untouchable plane was spying on them. Blackbird was also used in ‘Nam to fly over POW camps, so the captured soldiers could hear aforementioned sonic booms and were reassured they weren’t alone. Brian Shul recalls a time when a young servicemen asked him to drag an extra big boom for his father who was currently captured. Thusly he started carrying business cards that said ‘this boom’s for you’. If anyone gets the chance to real ‘sled driver’ I would recommend it.
The turning radius of an SR-71 at speed and altitude was 180 NM, which kind of invalidates Brian Shul, flying a racetrack pattern over some building. Brian had a tendency to exaggerate his exploits, i.e., exceeding Mach 3.5, while overflying Libya, when the tactical limit of the SR-71 was Mach 3.35 and slowing below 160 knots, while trying to fly-over a control tower in England. Unless he was in ground effect, just before touching down on a runway, at that speed, the aircraft would have stalled with an immediate pitch-up and loss of control.
@@icicle8263 No that is Mr Shul, the man with severe combat burns from Vietnam. Here is Mr Murray, callsign "Dutch-20". This is where he describes the A-12 and then the SR-71 as the family model with its extra crewmember and extra length, fuel capacity and more weight. ruclips.net/video/MGdxpqqsHl8/видео.html.
@@randymann7251 The only "blackbird" with an "F" in its descriptor is the YF-12A, the 2 seat version that almost made it to production as a high speed AIM-47 missile carrying/firing interceptor. Similar missiles that became the F-14's AIM-54 Phoenix and AWG-9 RADAR system. Here's a YF-12A in flight, notice its chines do NOT come all the way to the tip of the nose.

The missile was not loaded with a live warhead, the missile destroyed the target drone by physically hitting the drone. Impressive in a time where "look down/shoot-down" RADAR tech was in its infancy. There was the single seat A-12, then the 2 M-21(M for Mothership as it launched the D-21 (D for Daughter) drone to spy on China. M-21 pictured here with a D-21 daughter/drone on its back in teh launch position upload.wikimedia.org/wikipedia/commons/thumb/d/d8/LockheedM21-D21.jpg/330px-LockheedM21-D21.jpg The drone took pics, flew through China, popped its camera film and allowed the film to descend under a parachute, while awaiting modified C-130 Hercules orbited nearby in order to catch the film canisters mid flight. Very similar ops occurred for the satellite film canisters from the early Hexagon program. The M-21 backseater was known as the LCO or Launch Control Officer. The YF-12A backseater was the FCO for Fire Control Officer. The 3 variants of SR-71 "A", "B" and "C" all had a backseater that controlled all the various snooping and countermeasures devices. He was called the RCO for Reconnaissance Control Officer. A-12, M-21, YF-12A and SR-71 A/B/C all used the J-58 turboramjet engines except for the unpainted A-12 trainer referred to as the Titanium Goose, fitting as the A-12 was referred to as a "Cygnus" or baby goose. (Titanium Goose A-12 trainer pictured here upload.wikimedia.org/wikipedia/commons/thumb/7/75/A12Blackbird.jpg/330px-A12Blackbird.jpg It was a trainer aircraft with the backseat position added so that a training pilot can help train the front seater. This aircraft never got J58 engines and always had the 2 J-75 engines which kept her speed limited to just over Mach-2. During early test flights of the A-12, there were NOT many J68s available and there were a few A-12s that flew with one J58 in one nacelle with a J-75 in the other.
Not really, they were just more scared. Remember, schools were drilling children on nuclear attacks and every other story in the press was about the horrors and likelihood of a nuclear apocalypse.
Of course. Now if they told me they were conventional bombs then no way. Not only is a nuke less likely to explode from a crash, if it was "in my area" it going off would probably kill me whether I went to see it or not. In fact, seeing that writing on a plane and thinking just not going near it would save you would be indicative of stupidity.
Having had access to TS materials... The Soviets did make sort of a copy of the S/R-71. It's edges were much more rounded but looked almost identical. They ran theirs to the early 90's. Lyndon Baines Johnson unofficially changed the name of the S/R-71 by accidentally placing the S before the R in notes to the Airforce and Lockheed. Rather than correct him the AF/CIA/Lockheed changed the designation name.
So many remarkable design elements, particularly considering how long ago it was conceived. The pointed cones on the engines' nacelles were designed to deliver the shock waves from supersonic flight directly into the engine intakes to increase compression.
@@jonathanheck631 they also moved forward and aft depending upon speed and thrust requirements. I've heard a few stories about them not working correctly and flaming out. Which from the stories, when that did happen. It REALLY got the crews attention!!! Regardless of age and teething problems, Imo the A-12 and SR-71 is the sexist aircraft to ever grace the sky's!! From design, construction, to flight parameters it's simply an amazing AC. No it wasn't a G machine, no its climb rate wasn't the best, no it didn't have a big gun or high tech armaments. Because it didn't need it. Just light'em up and wave goodbye. I mean the SR-71 raced the sun........and won!!! SIMPLY AMAZING!! Thank You Skunk works!!
The SR-71 has always been my favorite aircraft. There is one in the Wright-Patt Air Force museum only 10 miles from my house. It was so surreal to actually touch one after a lifetime of only imagining it. But the A-12 came first, so it deserves its place in history. I always found it fascinating that these aircraft would leak fuel through their seams on the ground because when they flew at speed the heat would seal the plane completely. So the intentionally built them with loose plating. 😳
They were not designed to leak on the ground then seal up once heated up at speed. They didn't leak at higher altitudes because by that time the tanks weren't full anymore. Each area of the jet had a certain allowance for the number of fuel drips per unit of time were allowed. Certain areas allowed more leakage than others, some didnt allow any drips Once a certain level of "drips per hour" had been violated, the aircraft is pulled and its tanks are resealed. It was the sealant used that would degrade due to the thermal/chemical/physical movement of the joints that caused the leaks. Every 1-1/2 hours these beasts had to slow down/descend from Mach 3 plus/80,000+ feet and come down to 250knots/25,000 feet and sit on a tanked for over 15 minutes. A-12 held 68,000 pounds the SR-71 being longer held approx 80,000 pounds of fuel. The blackbirds became so heavy during fueling that towards the end of the filling session, the pilot had to engage a single afterburner in order to keep up with the tanker aircraft. They would stroke the afterburner in one engine and then control speed with the other engine. These birds were in a constant dance of acceleration/climb from a tanker with decelerating/descending to a tanker.
Something about this title sounds familiar. :) There's an A-12 sitting next to a SR-71 on show at Palmdale, it's an outdoor park displaying a bunch of historic planes.
The Museum of Flight in Seattle has an M-21, which is the A-12 based launch platform for the D-21 drone. I ate dinner underneath it once while I was attending my wife’s company party.
@@jamesweldon9726 that's uber koo!!! Lucky you, have a wife and got to eat dinner with her under that?! lucky man!!!! don't let her go!!! Sounds like a keeper to me. Wishing you and yours the absolute best in life! ( sorry I still quite haven't figured out this trolling stuff yet)
I suspect the Chinese leadership wouldn’t have wanted to admit to the existence and incursion of a plane so much more advanced than anything they had. And so beyond their capabilities to do anything about. So a big “nope” at the upper levels of Chinese military as well.
Simon, I have to share. My father was a civil Engineer in Okinawa during Operation Black Shield. He was almost court martialed for what happened to him there. Story as follows. My father had a passion for building model airplanes and displaying them in his cubicle and around the dorm during his time in Okinawa. He would purchase the newest ones from local stores around the base. One day, he found a futuristic jet at one small store that a local resident owned. Falling in love with the design, he immediately purchased it, built it and proudly displayed it on his desk the following week. It wasn't long before a high ranking officer ( I believe he said Colonel, but I can't be sure) was walking through the area and spotted the top secret A12 sitting on my father's desk. My father was immediately taken into custody, his model confiscated, and he spent several hours explaining to some very serious individuals that he he had purchased it and would show them where. Question. How did this store come to have a detailed scale model of the A-12 Archangel? Simple. The owner of the store was extremely talented, skilled craftsman and would sit off the runway in Okinawa and take pictures of the aircraft as they flew overhead. He would then go home and carve out models of these aircraft and sell them. After my father was released and informed he was to restrict his model purchases to the local base stores, the military then went to this man's shop..., purchased it and everything inside (including the man's photography equipment and all of his pictures) then paiud to have him and his family relocated to another part of the island far away from Kadena Air Base. Goes to show, the military and CIA do have a heart..., occasionally.
Well goes to show that the Civil Engineer did a better job of counter intelligence than the CIA did on that front, and restricting his model purchases from the beginning would mean that he would never have caught the "leak" and many wasted hours looking inside the camp when some random passer by who made models was the unwitting leak ... people see unknown things in the sky, people take pictures, if they have the skill they remake them .... its how humans have made money for millenia, and seems to be a weakness in intelligence thinking at that point
Some of the ads are really, really gross-- apparently saved for late night hours. We might attempt to believe RUclips had better standards, but that is probably a wasted effort..
Seriously, I see NO commercials anymore. I forget that RUclips has them. I got the free AdBlock thing. I'm on my desktop now, but sometimes I watch on my phone that doesn't have the app, and it sucks! I've had it for a long time, and no problems.
I remember taking a class trip to the USS Intrepid when I was a kid. I have always wanted to become a pilot and the most amazing plane I had ever heard of at the time was the SR-71 blackbird. I just learned today, because of this video, that the plane I got to sit in as a kid was not an SR-71 but an A-12 Archangel......mind blown.....this has rekindled my dream of flying a plane....😎
My step dad Carl, was the lead engineer for the engine at Pratt and Whitney aircraft for the SR-71 back in Connecticut. He is 95 years next month. Lots of memories for him.
@_SilverArrow_xxx I did, thanks! He actually was the engineer who solved the problem of the over-heating of the air inlet (RAM effect, he said) where the seals and solder on the electrical components would melt at over mach 3 from friction. They didn't want to use water coolant and another tank, so he had the idea to use the fuel to pass through the inlet housing. It had three positive effects: less weight with no additional coolant tank/pump, saved needing to enlarge the plane and pre-heated the fuel for burning efficiency.
Simon I have to say that I'm actually really impressed by this video. I'm a pretty enthusiastic aerospace enthusiast (and am studying for an aerospace engineering degree) and usually channels like this are great, but aren't ground breaking for myself as I usually have heard about a lot of this stuff. But I actually learned quite a bit of stuff this video, so major kudos to you and the research you and your team have done, it's always been top quality in any of your channels.
Kudos to you. I did ME for 4 semesters before changing my major back to EE and just taking a minor in ME. Fluids was a bitch... I'd rather count electrons than calculate the pressures a fluid excepts on a wonky geometry.
@@Lawrence330 I can totally understand your point! I spent 20+ as an A&P (while not one of my degrees, I do consider myself as an ME) before I went and had the bright idea of getting a computer science degree. I'm just glad I didn't have to do any hard maths with fluids!! Lol
Although I love the A-12 for it's incredible history and performance, I also have a family connection which I am very fond of. My dad worked for the CIA at Groom Lake when the A-12s were being tested there. He was part of the security team, and one of his interesting stories is about how he got hired by the CIA to begin with. Oddly enough, it all started with answering an ad in the newspaper, and he didn't even know what the job was until he was hired. During this time, he, my mom, and I lived in Las Vegas, where I was born. Every week he would go to the airport and get on a military plane (later they started using Janus Airlines) to fly to Area 51. He'd work there for the week, and at the end of the week he'd be flown back home again. I never get tired of asking him questions about his time there, and he remembers it fondly.
I, as one, know that when the A-12, or the SR-71 took off the first thing they did was fuel-up and then go into afterburner and get upstairs as fast as possible, and once they went into afterburner they stayed in afterburner. The way the J-58 engine was setup was that once you went into afterburner you stayed their, because your engine converted into a ramjet engine, your speed stayed right at Mach 3.2 or so and your fuel economy stayed good. You can look it up if you want. One remarkable aircraft. Michael said that. Bye for now my friend.
I heard from a friend the SR-71 fuel tanks were designed to expand with the skin of the aircraft and seal completely when heated by supersonic friction. Before getting up to operating temperature the tanks would leak, which was why they refueled in mid-air after takeoff. That is a ballsy way to deal with fuel leaks!
@@firstmkb I agree the fuel tanks are integral to the aircraft structure. The highest temperature occurs in the outer edges of the aircraft-they are trimmed with composite materials like the Space shuttle. Fuel is used to cool the aircraft and balance the Pitch (AOA).
@UCYyt9WQ9FZXGrgZBIpF_3KA I, as one, am not willing to argue the point of weather or not the A-12 and or the SR-71 had afterburners, It seems to me that if you are capable of writing in these comments....then for sure you are capable of looking that information up for yourself!!!! And if it's any good for you I'm going on 79 year's myself. But if I feel like making a comment about something I, as one, make DAMN SURE THAT I KNOW WHAT I'M TALKING ABOUT!!!! Michael said that. Bye for now my friend
Have read stories from pilots that claimed to be far over the top speed declared for brief moments. The limit is susposed to be the windscreen temperature limits.
@@firstmkb The SR71 also used a specialized jet fuel named JP7 which was specifically designed to have extremely low volatility, low vapor pressure, and high oxidation stability, all meaning that it's extremely hard to ignite. The stuff was so unwilling to ignite that every single time that the engines were started or went into afterburner they had to shoot an extremely volatile hypergolic chemical called Triethylborane into each engine in order to ignite the fuel. The airplane was incredibly fuel efficient once it got above about Mach 2.2 because above those speeds the engines would transition from functioning like normal turbojets to functioning as ramjets, the SR-71's had a fleet of tankers in the air wherever they needed while they were on mission, the only thing that gave them a hard limit in terms of mission length was the limited amount of Triethylborance (TEB) charges they had.
Both planes were designed to cruise in afterburner all the time. In fact the faster they flew the less fuel they used. The afterburner contributed the majority of the thrust at Mach 3+. In fact the engine ran as basically a ramjet with the inlets fully forward. I think this video missed a lot on their engines to be honest. They are the most interesting part of the a12.
At speed, the intakes provided over 60% of the aircraft's thrust. I don't know how that works, to be honest, but none other than Ben Rich, the lead engineer who designed the intakes, confirmed this to be true in his book "Skunk Works: A Personal Memoir of My Years at Lockheed". The improvement in fuel burn was mainly due to the intakes also, from what I've read. Of course, higher speed required a higher fuel burn rate (the laws of physics being what they are), but the burn rate per pound of thrust went down, as did the burn rate per mile. Those intakes were pretty friggin' amazing.
@@ztoob8898 it uses compression forces according to Bernoulli's principle for air compression being negligible at lower velocities, but inversely more important at higher velocities. The more you can slow down an extremely fast gas, the more it will increase in pressure at supersonic speeds. The engine adjusts for compression ratios at supersonic speeds to maintain an increasing thrust. So yeah, it kinda just pulls air in to move it forward using physics.
@@autisonm The J58 is a Turbo Ramjet. At High mach, the spike does the majority of the work compressing the air which is then bypassed around the main engine (compressor,combustion chamber and turbine assy) and into the afterburner section. This makes the afterburner way more efficient because this highly compressed air is unburnt thus having more oxygen. So in reality the afterburner is used constantly at high mach numbers, but it's not technically an afterburner at this point (because the majority of air is unburnt when it enters) just a large combustion chamber. The main Engine at this point is providing approx 20% of thrust It can be a difficult concept - I used to work on fighter engines, and understand supersonic intakes (shockwave and pressure reversions etc) mainly it's just witchcraft But basically what you're trying to do all the way through an engine is manage pressure and velocity - As Pressure increases so does temperature and velocity decreases - if you restrict the air then velocity increases and pressure/ temp decrease. Put your thumb over a hose pipe - high pressure behind your thumb with water slowing down - past the restriction low pressure and water velocity increases.
@@bencolbert6732 At supersonic speeds each inlet swallowed 100,000 cubic feet of air per second, the equivalent of two million people inhaling in unison. Once the engines are increased to military power, their rpm's and the air, flowing through them, remain constant. The inlet guide vanes on the face of the compressor will have rotated from the axial to their cambered positions, at speeds around 1.7 to 2.3 Mach. The engine is providing all of the thrust that it can produce, 17 % of the total thrust at Mach 3.2, with the inlet producing 54 % and the ejector 29 %. The face of the compressor actually has a slight negative thrust on the aircraft. The spike and shaping of the inlets provided an astounding 84 % propulsion efficiency, which was 20 % more than any other supersonic propulsion system ever built.
Ah, the good old C-5. Was stationed for years at Dover AFB and while they make great videos for their figures, those old beasts are really difficult to load!
Years of that thing flying a few hundred feet above my house has left me not only desensitized to it, but also annoyed by it's obnoxiously loud engines. Since then it's been replaced by the C-17 here, which isn't nearly as loud luckily.
Also, too; My gramps was in the US Army Air Corps. He helped to develop radar, during and after WWII. It took me many years to fully understand why he yelled at me when I stood in front of the microwave. He saw, or heard about more than a few Airmen getting cooked alive from unshielded radar. I didn't hear about this until after his death. My Aunt did a little segment about this on a local NPR station in NC. That was a few years before his death, but I didn't hear that recording until after he died. I have it on CD. I listen to it on his birthday.
I do to want to be mean but this is not an airplane channel it is one about massive projects and the A-10 was no more massive the most other aircraft. He does aircraft that were hard to design and create.
My cousin was a crew chief on the A-10 and one father's day he gave my uncle one of the bullet proof window panels, it's like 3" thick. What a cool gift. I asked him about obtaining one of the depleted uranium rounds but getting one of those was an impossibility unfortunately.
As an aviation addict, you caught me totally off guard with A12. I too like you have seen the SR71 in person. Since we’ve declassified so much information about the SR71, there has to be a whole lot more to learn about the A12. My bet you’ll keep hunting high & low for this astounding aircraft history. My bet is this A12 also scooted along our civil aviation as applicable & necessary avionics were implemented into planes we’re flying today. And yes, I hope you continue your delightful gold nugget shows that delight me each & every week (especially when there’s that fact v/s fiction approach). There’s.clearly some pre-NASA angle going on here. Talk about super cool 👍
If you read “Area 51: An Uncensored History of America’s Top Secret Military Base” by Annie Jacobsen, you’ll read a lot of the history of the A-12. Don’t let the book title scare you. It’s not all about UFOs and stuff. Really good book and comprehensive history of Area 51 and what they’ve done there.
There was a third variant: The YF-12A. The SR-71 replaced the A-12 because it was more advanced. It could carry more fuel, more payload, and a second crew member. It also developed more lift had a smaller radar cross section, thanks in part to the chines.
In Canada the Avro Arrow has become an urban legend, with a lot of incredible claims. Perhaps you can separate the wheat from the chaff of this 1950's interceptor.
@@scooterdogg7580 It was also obsolete when Sputnik was launched and the threat became Soviet ICBMs. It was designed really for one mission, as a highspeed Interceptor.
@@scooterdogg7580 I grew up in an RCAF family and ever since the cancellation of the Arrow they have never forgotten which party did it. That said, we can see from this video that interceptor aircraft had been rendered obsolete. The British also cancelled their maga-interceptor, the TSR-2 for exactly the same reason.
@@kimchipig The TSR-2 was to be a low level nuclear bomber to replace the V-Bombers. It was cancelled under American pressure and they offered Britain a deal on the F-111 as a replacement. The deal went sour after delays and cost over-runs on the F-111 so Britain did not get its new bomber until it developed the Panavia Tornado together with european partners.

On most aircraft, the afterburners are used infrequently. The Concorde, for example, flew in "supercruise" which is the term for mach+ flight without afterburner. But the SR-71 and the A-12 were designed to cruise in afterburner. The engine's core was primarily an air pump to feed fresh oxygen to the afterburner. Once the aircraft neared mach 3, the inlets and ejectors provided most of the thrust, the afterburners second, and the engine core a distant third. That's just the way it worked.
Was he though? The swept back wings come from German research and the Germans also developed a high-altitude spy plane in WW2, which was very, very similar to the basic design of the U-2. It's called the DFS 228. They benefitted quite a bit from captured German research. However, the Americans produced very innovative designs during the war as well and yes they also had great engineers. I am just saying that there is a lot of German technology in the post-war jets of the US. West Germany even developed a plane very similar to the F-117 before US pressure resulted in the cancellation of the project. Look up the MBB Lampyridae. *Edit: And the design of the A-10 was heavily influenced by the "Unnamed" Junkers Ground Attack Aircraft. Hans-Ulrich Rudel was also an advisor to Fairchild-Republic.
@@generalripper7528 The US had swept wings. You have oversimpliffied the entire process of both the design and manufacturing of these extraordinary aircraft. When they started this, titanium couldnt be formed. They invented everything necessary to form and machine titanium from scratch. That's like the full lifespan of an entire civilization in a year, by one team on one project. If Johnson isn't a genius, then why have Archangel and Blackbird NEVER been surpaassed?
My shop teacher when I was in high school in the 1980's who served as a radar operator at a base in Vietnam during the war claimed that they tracked a SR-71 (I'm thinking it was an A-12) with an airspeed of 2,100 knots (2,400 mph). He said they were told not be tracking these planes on radar but I guess they decided to do it once. He said it was common knowledge on the base that the spy plane was capable of Mach 3.5.
Mostly unrelated, but I used to live near an Air Force base and saw a B-2 Spirit once, among the quietest planes I've ever seen (assuming similar altitude to the usual C-130s they flew out of there). Navy Hornets, OTOH, are so effing loud I'm surprised they ever hit a target. You can hear them coming for miles and miles.

Very interesting comparison of two great aircraft. One small note: jet engine thrust is measured in pounds-force (lbf) not pound-feet (lb-ft). The latter are the units of torque.
It was used as a testbed to develop technologies that were later needed during the development of the “Aurora” hypersonic aircraft in the 1980s, which is still classified but has been seen and heard by lots of people
To show how classified these planes were I was stationed an a northern base in the US when a SR-71 declared an in flight emergency and needed to land. Our base was chosen as the place to put it down. We had just a short time to prepare. The base scrambled to get 20 foot high curtains ready. They formed a 3 sided walls and when the plane landed it pulled into said curtains and shut off it's engine. A fourth wall went up behind it. NOBODY but the pilot was allowed inside. We placed 50 security forces around the plane but they were not allowed withing 75 feet of the curtains. By the end of the day we had a flock of C-130's land with security folks to replace ours, maintenance folks to work on the plane and 2 pilots to choose from for the return flight and they even brought their own fuel trucks (loaded with fuel) to refuel the plane. By the next afternoon the plane was fixed. Th rear curtain was dropped, the engines fired, the front curtain dropped and it's taxi was also it's run up to speed and it was off the ground in seconds and just a memory a few seconds later. This was what the folks on a US Air Force base go to see of this plane. Nothing unless you saw it land or take off. Ohh one more thing, if you were seen pointing a camera in it's direction all HELL would break loose. lol Just my $0.02
I grew up in Northern California. I had the luck to see SR-71s flying around every once in a while as a kid. Sometimes just a few thousand feet up over Sacramento. It was always a huge surprise, and I wondered what the hell was going on for it to be so far from Beale AFB, so low over a populated area.
Actually, they needed their own fuel trucks, because the SR-71 (and the A-12) burned JP-7, not JP-4 like everything else; I doubt any Air Force base except Beale kept JP-7 on hand.
Not surprised this is the most viewed video. The development of Kelly Johnson and fast planes is one of the coolest things human has ever done, if such a thing can be quantified.
I got to watch the SR-71 out at Skunkworks in Palmdale when my dad worked for Lockheed. They are so so so so so so so soooooo loud. Such an amazing aircraft...BUILT WITH A SLIDE RULE.
Great and informative video ! I've only ever really heard much about the SR-71s as my dad worked around them back in the day; its nice to hear about what came before.
This video needed to be made ! Thank you ! My father was an F 4 fighter pilot in Vietnam and while stationed in Japan he was driving across base and part of the road crossed the back landing strip . He was off duty driving with my mother and brother and an airman guard left the security gate open and an A 12 landed right in front of them. Nobody had ever seen any plane like it before and my brother thought it was a UFO. My father even got a bit in hot water just for seeing it and he was sternly told he DID NOT see that plane and then told my mother and brother they did not see it either and never spoke of it again until recently. I am also fascinated by skyscrapers . What if you did a comprehensive video about the evolution of all the world record skyscrapers leading up to Birj Khalifa and beyond? I would love that
In 1973-1974 I was stationed on Okinawa at Camp Hauge, the base was about a half mile from the end of the Kadena runway. We always knew when the Habu was getty ready to take off. Two tankers would take off ahead of it. I lost three coffee mugs to the SR-71, the vibrations were so great when SR-71 Habu took off and did its tail stand over us, the cup seemed to walk right off the edge of your desk falling to floor. That was frustrating, especially if you had not had your first cup of morning coffee yet.. It would be gone for a couple of hours the return. We would watch some F-4 Phantom fighters take of, so we knew we had a show coming up. Maybe a mile out you would see some red and white lights come on and the Phantoms would disappear into the clouds. When the Habu closed to within a quarter mile from or base, the Phantoms would try to ambush them. When the Phantoms dropped out of the clouds, the Habu's gears would come up, then they apparently got permission to leave the flight pattern. The nest thing that happened, the Phantoms, would drop in behind the Habu in a kill position. As the got over hear, the Habu would do a tail stand and nearly bust our windows. The Phantoms were already in burners, when everybody went ballistic, straight up sort of. It seemed like it only took a couple of minutes for the Habu to loose the Phantoms and they had to break of their pursuit, a couple of minutes later the Habu would be back in the landing pattern, ready to land. Used to have some super 8mm film of the Habu coming in for a landing. You could really feel the pressure in your chest as it took off over you, like the Habu did back in 1973-74.
“…considering the speed of the plane, the codename Oxcart is just a little bit ironic.” Which is in itself ironic. Which means we’re looking at the uniquely British phenomenon I call “recursive irony”... which is so ironic it’s been used as a cure for anemia in wartime emergencies...
We can only repeat the RELEASED top speed and altitude of these planes, which are astounding. The ACTUAL limits will never be known, but from first-hand accounts over the years, we're considerably more than the "official" records.
I was on Okinawa/Kadina with F106s in 1968 and to our knowledge the Blackbirds were SR71s. We knew of a previous version called the YF12 which was a squadron of interceptors. I also "heard" that the YF12s were reconfigured as SR71s. I did not know of the A-12.
US : We will use the epitome of technology, the fastest plane ever developed to spy on you. Vietnam : wierd flex but okay. Most of our military structures are below ground
Ah, its fine, we have underground sonography radars now :) I mean, archeologists can see how many cities got buried underground already without digging.
You named her after "Sleeping Beauty"? ;-) If so, nice. If for some other reason.... still nice. Aurora is a beautiful name. ….and I like the humorous irony of your comment.
Heck yes! I'd say GPS counts as a megaproject! The array of applications and just how reliant modern technology has become on it is incredible. It's so necessary for modern tech that there are 3 other separate world wide navigation systems built by other countries that don't trust the US and so created their own to ensure they have access to a GPS system. (Russia, China, and Europe all have their own systems) Plus Japan and India have their own regional positioning satellites (in geostationary orbit so the ground trace covers their respective countries) to make sure their countries are covered.
In Palmdale CA, there is an A12, SR71 Blackbird, U-2, and a D-21d drone(same engine of the SR71 I think) on display and it’s free. It’s called Blackbird Airpark. There is also another aviation museum next door. It has everything an aviation fan could ever want to see including a F104 starfighter. It’s also free. While driving there you drive through The Skunk Works. I drove 16 hours to get there and it was worth every second.
I was pleased to have had an opportunity to visit the CIA headquarters in Langley, Virginia a few years ago to assist in delivering some original art for display at the CIA's private museum. I believe that the oil paintings of the A-12 that we delivered were the images seen in this interesting episode. That occasion was just prior the dedication of an A-12 that is now installed on a pedestal outside the rear of the CIA HQ building. We drove under the A-12 on the way out, but they were still finishing up the display area.. We also got a tour of the CIA Museum [closed to the public, with some display items viewable at the CIA Museum's www site] with the museum's Curator. All of the CIA brass and a number of very senior military people were present during our visit, as it coincided with the Director's annual Christmas party for employees. We were supposed to get our picture taken standing next to the big CIA seal on the floor of the building's entrance area, but unfortunately the CIA's official photographer was busy at the Christmas party, and use of our own cameras was prohibited inside the property. It was a very fun and interesting experience.
It was not a flyby it was a take off with the landing gear staying out. The landing gear apparently created instability and the pilot decided to land on the salt flat instead of risking a turn.
@@barthoving2053 Yes, I'm aware of that from the vid, as I have excellent listening skills. This was just a joke.... (i.e. ANY flyby at 6 meters would be an interesting flyby.) Get over yourself.
For a more in depth history of A-12 Oxcart/Archangel I would highly recommend Annie Jacobson's "Area 51: An Uncensored History of America's Top Secret Military Base". There is a lot more in there other than just the A-12 but since the A-12, and the U-2 before that, is so closely connected to the building and development of the Groom Lake base it covers the A-12 history extensively.
This video brought back so many vivid memories for me. The cosmic top-secret projects are very alluring, but to those who live with the memory of them, it can take decades to stop having nightmares. 50 years ago I served in the black area where the SR-71 Blackbird was maintained underground and rose on an elevator before taking off in mere seconds.
Interesting what Mr White shared. I'm only aware of the -71 operating out of Kadena and Edwards Air Force bases. Now, someone several years ago told me he saw a TR-3B come out of an underground storage at Edwards, rotate slowly and then instantly was gone. > Mr White, if you ever read this reply, what can you share about other black projects?
@@brianjob3018 The Blackbird was the most awesome of all possible thrills to witness as it emerged silently from underground in the black area of Kadena AFB during my tour there. Jimi Hendrix had just recent died, and soon after I found myself on what we called "the Rock." I worked mostly the grave shift while stationed there, and what went on after dark caused me to have nightmares for several years afterward after my 4 years in the USAF ended. It was after I was discharged (honorably) that I realized how much background research was done to check out my friends and family back home in order to have a top-secret security clearance to be so close to the super-secret aircraft that could be used to deploy tactical nuclear weaponry, and perform high-altitude reconnaissance too. The technology that I saw being used over 50 years ago is still a century ahead of anything the day-to-day person has ever imagined yet. Lockheed was the next step, and I wanted no part in whatever was going on back then, so I declined their offer to come work for them. The experimental particle beam weapons I saw in 1969 were pretty to see at night, but my conscience compelled me to stay away from all of it no matter what the financial reward might be. The Space Force has existed for decades, and now the public is hearing about it.
The A-12 was also equipped with air-to-air missiles. One measure of the spectacular technological success of the A-12 and SR-71 is that 50 years later, no plane has been produced that even matches, much less exceeds, their performance.
Actually the A-12 that the CIA flew in 1967 and 1968 in SEA did not carry any missiles, only cameras. It's brother, the YF-12A, which initially set the speed records was designed to carry a precursor to the AIM-54 Phoenix, which was the AIM-47 Falcon...Initially the A-12s that flew in mid 1962 were equipped with J75s because the J58s were still having teething problems after 4 years of development. By 1963 all the A-12s had been re-equipped or built with J58s. The J58 was NOT a ramjet..... it was an after burning turbojet with a bypass that overcame aerodynamic issues with the engines flying at speeds over MACH 2.5. This bypass principle was later used on the big fan jets we see today on most jets... especially airliner engines..
While they are spectacular, I guess there is not much need for that specific capability. It's very expensive to develop, not fault proof, can still be shot down. And then there are spy satellites nowadays which can provide very precise picture. In a sense, they are the logical next step. Much faster and higher. ;)
@@jeffprice6421 I didn't say there were any that have been shot down. But it's possible, to be fair, that's also true for spy satellites. But it was even mentioned in the video.
The Soviet titanium is funny, but it’s even funnier that the theory used to design the F-117A stealth fighter was developed by a soviet scientist who was completely ignored by the soviets, and ended up publishing the theory, only for Lockheed to find it and use it to create the stealthiest plane ever made.
@@bautistabautista7989 That communism almost always discard new ideas no matter what it is; political or technical. The idea of free thinking and creativity is frowned upon.
Just like the atomic bomb. Heidelberg was well ahead of project Manhattan but he didn't get anywhere near the same resources because Chaplin mustache man though it was all juice science, and wouldn't send him what he needed so Oppenheimer caught up and completely surpassed Heisenberg in no time Were lucky Heisenberg didn't have the resources he needed. VERY lucky
"pretty excellent at reflecting radar"? That is exactly what you DON'T want a stealthy aircraft to do. Either absorb or deflect away, but if you're deflecting; you have to be careful in which direction you are doing so.
@@YannisG784 Yes, everything; from the choice of material to the way they structure the material, angle of the surfaces, the paint they coat the body in, the way they position the air intakes for the jet engine (compressor fan face is a MAJOR radar cross-section). As an example when we had a type of a ship in the navy, switching the round hand railing for a square handrailing with one of the edges pointing sideways made a huge difference for the radar cross-section like this; , as the radar bounced more either up in the air or down into the water.
The plane shown in the still photo at 17:22 is actually the YF-12, another cousin in the family. It was the only two-seater of the group. This plane never went into production.
I spent part of my childhood near Beale Air Force Base in California and I regularly got the privilege to watch the SR-71 fly, even getting close to it sitting on the tarmac during airshows (cordoned off with guards, of course).
There is an A-12 inside the museum in Mobile Alabama. I thought it was a Blackbird till I was 20ft from it and saw the single canopy. Very interesting storyboard next to it as well.
Ben Rich, the leader of the Skunkworks after Kelly Johnson retired, wrote an excellent book about his time at the Skunkworks that includes the development of the U-2 and the SR-71.
95,000 feet was the maximum altitude that they would admit to. You should take the accuracy of the flight model with a significant quantity of salt, but in 'Chuck Yeager's Advanced Flight Trainer' (the last word changed from 'Simulator' due to a dispute with Microsoft over 'Flight Simulator') from Electronic Arts, it was possible, with a considerable amount of care, to get the SR-71 modeled in the game up to around 130,000 feet, although keeping it in level flight at that altitude was a question of 'how fast do you make a mistake and lose it?'
At around 12:20, you describe the afterburners of the A-12 being "used for takeoff and evasive maneuvers". They were indeed used for takeoff, but they were LEFT ON the whole time they were aloft. The A-12 and Blackbird were designed to run continuously on afterburner - not just for takeoff. Indeed they were most efficient at top speed/full afterburner. As for evasive maneuvers, all the planes had to do was go faster or move the stick a little.
Later variants also had a jamming pod in the tail that could confuse missile tracking gear as well. It was code named Oscar Sierra but was nicknamed "Oh S____" by the pilots because that was their reaction when it came to life.
@ I think that for the SA-2 Guideline SAM, the A-12 operating at upwards of 95,000 FT, altitude was the main defeating factor, not speed. Years after the -12 was retired, North Korea launched an SA-5 Gamon at a -71 and it exploded at about the same altitude and about a kilometer or two behind. I believe that was the closest call the -71 ever had.
@ Simply put, I'm going to maintain that the SA-2 was not effective past 80,000 ft but the SA-5 clearly was. The mach 3 speed of our planes was definitely a complicating factor for the missles. I can't comment on fuel limitations. Please do your own research into the exact capabilities of the Soviet-designed SAMs operational when the A-12 was operational.
it was a good strategy, until the missiles could catch up to them. Same energy with us pursuing stealth. Build a fast plane = my missile is faster Build an invisible plane = this radar is about to ruin your whole career Imagine the amount of money spent to make something faster/stealthier, and "I spent less than you on a gadget that makes your stuff obsolete".
At 12:29 you mentioned that the afterburner was used for takeoff and periodically when needed. This is true, but the J-58 engine was designed to operate continuously in afterburner.
It's basically a combination between a turbojet engine and a pulsejet engine. Crazy unique design, and between the disparency between the claimed, estimated top speed, and the actual records the Blackbird holds, I'd say we, the general public, do not know what that aircraft's actual top speed is, because it gains power as it goes faster. I'd reckon the nosecone's ability to tune out the shockwave would be the only thing stopping it.
@@460EFI Not pulse jet but ramjet & the absolute limiting factor in it's top speed was the maximum temperature of the cockpit glazing & the composite materials used.
And here I was thinking you'd come here looking for Drachinifel's latest video upload. I've done it. If you're not a follower of "The Drydock" you should be.
I did some contract work for Lockheed back in 99-00. I worked out of Ft.Worth but was shuttled to Marietta for a month, and shortly before my contract was up, I was sent to Lockheed's Palmdale facility. At that time... they had an SR-71 parked at each corner of the base and an F-117 on a pylon at the main facility. Gained a new perspective on "first impressions" that week. It was less than a week spent there, but I saw some wild stuff. Examples... I saw the JSF-C (F-35) prototype/test bed without its skins, awaiting completion and testing, saw (at that time) Northrop's next-gen lifting body space shuttle replacement in a rented hangar on site (spooky... half finished, full size, just standing up in the dark in this huge hangar) and I was able to attend an informational briefing from an F-22 test pilot (F22 was still in proving phase) and his stories were mysterious, entertaining and at times jaw-dropping. Helluva plane, from what I could gather. Didn't even get "the whole picture" of what the plane could do, and I remember thinking... "boy, it would really suck to meet one of those coming the other way." And that was 20 years ago... Knowing what I know now... with the advancements of the program... A half dozen Raptors would lay down one serious "sh!t show" for the enemy for hundreds of miles in all directions (in the air). I'm no aviation expert. Not a pilot (aside from a couple dozen hours in a twin engine prop). I was simply crossing paths with the industry and had a true passion for military hardware - still do). Was in my my late 20s. Was a pretty fantastic several years of my career. --- Good video. Thanks for doing this. Enjoyed it.
There was another variant of the A-12 that continued to fly into the late 1970's. It was the YF-12c. Someone got the crazy idea to try to make a fighter out of an A-12 but apparently didn't consider that the plane could literally out fly much of it's ordinance. I actually had the opportunity to very briefly see the only remaining YF-12 while on a tour at Edwards AFB with my high school ROTC unit in or around 1977. They had it sitting in a hangar with armed guards at the hangar doors. After pointing the aircraft out to the public information officer we were told that it must've been a SR-71 as our AF bus immediately started speeding out of the area. Go figure....
The classified information on the SR-71 is mind blowing stuff! I wish that since they retired the SR-71, they could release it’s mastery of the sky. People who have seen it fly, like I have , know it is still the best thing ever to have flown!
You're close, but not quite right. The YF-12A was a preproduction design for a high speed _interceptor_ (not a fighter) - three airframes were built, flown and tested. The production version was to have been called the F-12B, but the program was cancelled before any were built. There was never a YF-12C - That was a fictitious designation applied to NASA's SR-71 to help keep it secret. I've encountered this idea that the plane could "out fly much of its ordinance," before but I'm baffled as to where it comes from - The YF-12A carried only one weapons system, the AIM-47 Falcon (also known under other designations such as GAR-9), a predecessor of the US Navy's AIM-54 Phoenix, and those things *_definitely_* go faster than anything in the Blackbird family.
The story of the A-12 "Oxcart" was mentioned by President Johnson in the early 1960s. It became declassified in the early 1970s as I read about the YF-12a and its related versions, the D-21, in 1972.
The A-12 or its predecessor that looks just like it was already flying out of Kadena Air Base in Okinawa in 1959. Therefore it was most likely the CIA version that was highly classified. I don’t know what their designation for it was. It looks exactly like the A-12 or the SR-71 blackbird but I saw it at Kadena Air Base in 1959. They would bring it out of a remote hangar at dusk and it would take off on its mission. I don’t know why after all these years they still say it was built in the 60’s. There were no markings on it, just the flat black color. The people directing it were Air Force personnel or looked like it as they wore Air Force fatigues. Anyone else remember seeing it at Kadena in 1959 that would care to comment? I saw it from approximately 50 feet away on the other side of the security fence.
@@matthew1995king Not sure what you mean, but the U-2 has a distinguished career, and continues to fly today. So far, that's 64 years of service. I'm a Blackbird fan more than a U-2 fan, but the SR-71's 35 years of service pale in comparison, even if she is a far more stunning aircraft!
When it comes to naming stuff, the military's creativity and pure badassery are unrivaled. You have Blackbird, Archangel, Valkyrie, Nighthawk, The Big Boy, Castle Bravo/Romeo/Yankee, Tsar Bomba, MOAB, Gat12 Gatling aka "The Crowd Pleaser" the list goes on...
I was probably at that same airshow ... 1983 up near Redesdale, Otterburn if I remember correctly. There as part of an American Airborne contingent training with some of the SAS guys .... I remember the SR 71 well and even have pictures I took with a little Minolta Weathermatic 110. I just can't remember if we were in Otterburn that day or perhaps we were staging at the time preparing for a jump out of Alconbury. We were all over the place, so I can't be sure, but I have pics of the SR 71. It was the second one we had seen having seen one once before near Marsh AFB in California when we were preparing to return to Bragg after Gallant Eagle '82.
@ACF you're correct, they did leak oil when they were cold as they were made to heat-up and the tiles would expand at altitude and speed. I had it explained to me once and I cannot remember if it was part of an oil cooling system that leaked or what .... but they did leak when cold on the ground. I was fortunate enough to actually meet an A-12/ SR71 pilot, retired, in Memphis, TN in 1990. He had me up to his office even and showed me all of his memorabilia which included walls lined with pictures of the various jets he flew with him, et al, beside/inside them. And he told some pretty good stories. He's passed now but we stayed in touch for years afterwards.
@@Hattonbank no, it wasn't figurative .... literally they leaked. As I explained, the bird was made to be flown fast and hot and its pieces would expand at speed and altitude (much like atmospheric reentry in a space capsule module) so that everything sealed tightly. On the ground, when cool, it would drip fluids.
@@GalloPazzesco Sorry, I think I inadvertently replied to you instead of Rylee when he replied to ACF saying that a Corvette engine would not fit into a Miata, ACF, I thought, was speaking figuratively. I agree with you about fuel leakage when the aircraft was on the ground, and the friction of high speed expanding the metal to close the seams. Apologies for replying to the wrong person.
My dad pointed out once that the reason these planes’ top speed was classified is because they couldn’t actually find where they stopped accelerating before they’d rip apart from aerodynamic stress. Meaning that the fastest air breathing plane ever never was never even able to reach its top speed.
Yes your dad is correct. Not an engineer myself but others here have spelt out that the A-12 would essential rip itself apart. So pilots were speed limited
This is actually true of most supersonic aircraft with variable geometry intake (the J58 installation is those mobile cones and trap doors; on F-15, those would be sloping ramps). As you gain speed and keep the oblique shock adapted, the pressure gradient in the intake gets larger, increasing thrust -- at such regime, the engines are just pumps to get rid of the air from the intake that is actually providing the propulsion. That is the reason the F-15 speed, for instance, is often described as "Mach 2.5+", since Mach 2.5 is not really the limit of what the propulsion system can deliver. This is not as much "classified" as "never really tested".
Considering the heat at which titanium loses it's structural rigidity it's been estimated the top speed of the A-12 (or Blackbird) is around Mach 3.5 - 3.7 At that speed the heat generated by air friction would heat the metal to the point the plane would fail.
there was a Popular Science or Mechanic issue that detailed in great depth how SR=71 was developed and manufactured. It was almost impossible to build it.. It took lots of problem solving to make it fly. It was never enough to have just titanium, because many of the problems to be solved was related to high temperature that created problems . It was a fascinating issue! I was too cheap to buy the issue online if any..
I had the honor of watching a Sr-71 Landing at an airbase in Nj in the early 80's while on an cable car ride in Great adventure Nj. I know the air base, cant remember the name, Black, long, loud and you can not mistake the shape. It was awesome.
My grandfather, Victor Horton, flew the YF-12A during his NASA career. It was a missile-armed, 2-seat interceptor version of the A-12. He said it was a better plane than the more famous SR-71A, which he also flew. Three were built, but Grandpa's YF-12, 60-6935, is the only one left; 6934 and 6936 were lost to accidents, although the salvageable back half of 6936 was combined with the forward fuselage from an SR-71A static test article to create the "SR-71C" (affectionately dubbed "The Bastard" by flight crews). Grandpa flew that one as well and said it never handled quite right, so was retired after only a few years.
No he did not

After being wounded in Nam and months in an Army hospital in Japan, I was assigned to Okinawa. Our Army Ordinance Company was next to Marine Camp Schwab in Nago District where the "Ospreys" are being relocated. I was there June 67' to March 68'. I think it was late 67' that I saw the Blackbird at about 12-15,000' cutting a large arc and losing altitude for Kadena to our south. Being around planes most of my life I could not identify it and asked another troop what it was. He simply said "Blackbird". I would on occasion see them and witnessed a takeoff from Kadena while on a supply truck run to one of our dumps next to Kadena. I also parked at the end of the runway to watch 52's labor off the runway and immediately rendezvous with KC-135's to top off for the Nam run. 60'000lbs of bombs of different sizes for different missions. In Nov 66' I was a rifleman with A 2/27, 25th Div in a rain forest not far from the Cambodian border in 3rd Corps. Three 52's in formation, each with 30 2'000lb bombs hit an area where a NVA regiment from the 324B Division was thought to have regrouped after kicking our ass the week before. We were 2+ miles from the strike. I saw the 52's thru a break in the canopy by sure luck. I looked up because I heard a "hissing" sound" which turned out to be the bombs falling. All hell broke loose as the earth shook under our feet and things fell from the big trees. The next morning we took my company to sweep the strike Zone. You could drop a house into each of those 90 craters. Each bomb shattered a football field size clearing. We found collapsed bunkers and much blood in the area. What was left of them went over into Cambodia and we went back to Cu Chi for Thanksgiving.
Sorry, I got carried away with memories.

Thank you for your sacrifice and service sir. Being on the ground in Nam was 1,000 times more intense than being in the air.

Did the Clintons receive payments to help make the deal happen? Probably, they are as corrupt as any other politicians. Does this excuse any actions done by others in the government? Nope.
Interesting fact: SR-71 was actually tasked to do the opposite of being stealthy sometimes. During one operation Maj Brian Shul (author of sled driver) was flying the blackbird and was told to take up a racetrack pattern just over the building in which many leaders of non friendly countries were having a meeting. The idea being they could hear the distinctive double sonic boom ever few minutes and would know the untouchable plane was spying on them. Blackbird was also used in ‘Nam to fly over POW camps, so the captured soldiers could hear aforementioned sonic booms and were reassured they weren’t alone. Brian Shul recalls a time when a young servicemen asked him to drag an extra big boom for his father who was currently captured. Thusly he started carrying business cards that said ‘this boom’s for you’. If anyone gets the chance to real ‘sled driver’ I would recommend it.
The turning radius of an SR-71 at speed and altitude was 180 NM, which kind of invalidates Brian Shul, flying a racetrack pattern over some building. Brian had a tendency to exaggerate his exploits, i.e., exceeding Mach 3.5, while overflying Libya, when the tactical limit of the SR-71 was Mach 3.35 and slowing below 160 knots, while trying to fly-over a control tower in England. Unless he was in ground effect, just before touching down on a runway, at that speed, the aircraft would have stalled with an immediate pitch-up and loss of control.
And I'm the proud owner of two of Brian's books, early copies of "Sled Driver" and "The Untouchables."

The "F is for Family model"
@@icicle8263 No that is Mr Shul, the man with severe combat burns from Vietnam. Here is Mr Murray, callsign "Dutch-20".

Similar missiles that became the F-14's AIM-54 Phoenix and AWG-9 RADAR system. Here's a YF-12A in flight, notice its chines do NOT come all the way to the tip of the nose.

The lack of chines necessitated a large ventral fin to be extended after takeoff as the landing gear was retracted this fin came down in the center of the aircraft. 2 additional non retractable ventral fins were located under each engine nacelle. ONLY the YF-12 had these 3 ventral fins.

YF-12A tests flying at over 75,000 feet at Mach 3 were able to not only lock on and then destroy a maneuvering target drone jet flying at 750 feet. The missile was not loaded with a live warhead, the missile destroyed the target drone by physically hitting the drone. Impressive in a time where "look down/shoot-down" RADAR tech was in its infancy. There was the single seat A-12, then the 2 M-21(M for Mothership as it launched the D-21 (D for Daughter) drone to spy on China. M-21 pictured here with a D-21 daughter/drone on its back in teh launch position upload.wikimedia.org/wikipedia/commons/thumb/d/d8/LockheedM21-D21.jpg/330px-LockheedM21-D21.jpg The drone took pics, flew through China, popped its camera film and allowed the film to descend under a parachute, while awaiting modified C-130 Hercules orbited nearby in order to catch the film canisters mid flight. Very similar ops occurred for the satellite film canisters from the early Hexagon program. The M-21 backseater was known as the LCO or Launch Control Officer. The YF-12A backseater was the FCO for Fire Control Officer. The 3 variants of SR-71 "A", "B" and "C" all had a backseater that controlled all the various snooping and countermeasures devices. He was called the RCO for Reconnaissance Control Officer. A-12, M-21, YF-12A and SR-71 A/B/C all used the J-58 turboramjet engines except for the unpainted A-12 trainer referred to as the Titanium Goose, fitting as the A-12 was referred to as a "Cygnus" or baby goose. (Titanium Goose A-12 trainer pictured here upload.wikimedia.org/wikipedia/commons/thumb/7/75/A12Blackbird.jpg/330px-A12Blackbird.jpg It was a trainer aircraft with the backseat position added so that a training pilot can help train the front seater. This aircraft never got J58 engines and always had the 2 J-75 engines which kept her speed limited to just over Mach-2. During early test flights of the A-12, there were NOT many J68s available and there were a few A-12s that flew with one J58 in one nacelle with a J-75 in the other.
Looks kinda like a station wagon.

"The plane has nukes on it. For your safety, please keep away".
The fact that this worked proves people were much, much smarter back then.
Derkie84 now you have phone zombies
well if an f35 crashed near your area and someone told you it had nukes would you really go see?
Not really, they were just more scared. Remember, schools were drilling children on nuclear attacks and every other story in the press was about the horrors and likelihood of a nuclear apocalypse.
Legal segregation existed in the US in the 60s so I strongly disagree with people being "smarter" back then.
Of course. Now if they told me they were conventional bombs then no way. Not only is a nuke less likely to explode from a crash, if it was "in my area" it going off would probably kill me whether I went to see it or not. In fact, seeing that writing on a plane and thinking just not going near it would save you would be indicative of stupidity.
Designed in the 50s but still looks futuristic.
Having had access to TS materials... The Soviets did make sort of a copy of the S/R-71. It's edges were much more rounded but looked almost identical. They ran theirs to the early 90's. Lyndon Baines Johnson unofficially changed the name of the S/R-71 by accidentally placing the S before the R in notes to the Airforce and Lockheed. Rather than correct him the AF/CIA/Lockheed changed the designation name.
So many remarkable design elements, particularly considering how long ago it was conceived. The pointed cones on the engines' nacelles were designed to deliver the shock waves from supersonic flight directly into the engine intakes to increase compression.
@@jonathanheck631 they also moved forward and aft depending upon speed and thrust requirements. I've heard a few stories about them not working correctly and flaming out. Which from the stories, when that did happen. It REALLY got the crews attention!!!
Regardless of age and teething problems, Imo the A-12 and SR-71 is the sexist aircraft to ever grace the sky's!! From design, construction, to flight parameters it's simply an amazing AC. No it wasn't a G machine, no its climb rate wasn't the best, no it didn't have a big gun or high tech armaments. Because it didn't need it. Just light'em up and wave goodbye. I mean the SR-71 raced the sun........and won!!! SIMPLY AMAZING!! Thank You Skunk works!!
Every technology they've withheld will look futuristic
Honestly I thought the A-12 was new. Awesome looking air craft
The SR-71 has always been my favorite aircraft. There is one in the Wright-Patt Air Force museum only 10 miles from my house. It was so surreal to actually touch one after a lifetime of only imagining it. But the A-12 came first, so it deserves its place in history. I always found it fascinating that these aircraft would leak fuel through their seams on the ground because when they flew at speed the heat would seal the plane completely. So the intentionally built them with loose plating. 😳
They were not designed to leak on the ground then seal up once heated up at speed. They didn't leak at higher altitudes because by that time the tanks weren't full anymore. Each area of the jet had a certain allowance for the number of fuel drips per unit of time were allowed. Certain areas allowed more leakage than others, some didnt allow any drips Once a certain level of "drips per hour" had been violated, the aircraft is pulled and its tanks are resealed. It was the sealant used that would degrade due to the thermal/chemical/physical movement of the joints that caused the leaks. Every 1-1/2 hours these beasts had to slow down/descend from Mach 3 plus/80,000+ feet and come down to 250knots/25,000 feet and sit on a tanked for over 15 minutes. A-12 held 68,000 pounds the SR-71 being longer held approx 80,000 pounds of fuel. The blackbirds became so heavy during fueling that towards the end of the filling session, the pilot had to engage a single afterburner in order to keep up with the tanker aircraft. They would stroke the afterburner in one engine and then control speed with the other engine. These birds were in a constant dance of acceleration/climb from a tanker with decelerating/descending to a tanker.
Something about this title sounds familiar. :)

Another A-12 is on display at the Medal of Honor Aircraft Pavilion in Mobile, Alabama, next to the battleship USS Alabama.

I suspect the Chinese leadership wouldn’t have wanted to admit to the existence and incursion of a plane so much more advanced than anything they had. And so beyond their capabilities to do anything about.
So a big “nope” at the upper levels of Chinese military as well.

Simon, I have to share. My father was a civil Engineer in Okinawa during Operation Black Shield. He was almost court martialed for what happened to him there. Story as follows.
My father had a passion for building model airplanes and displaying them in his cubicle and around the dorm during his time in Okinawa. He would purchase the newest ones from local stores around the base. One day, he found a futuristic jet at one small store that a local resident owned. Falling in love with the design, he immediately purchased it, built it and proudly displayed it on his desk the following week. It wasn't long before a high ranking officer ( I believe he said Colonel, but I can't be sure) was walking through the area and spotted the top secret A12 sitting on my father's desk. My father was immediately taken into custody, his model confiscated, and he spent several hours explaining to some very serious individuals that he he had purchased it and would show them where. Question. How did this store come to have a detailed scale model of the A-12 Archangel? Simple. The owner of the store was extremely talented, skilled craftsman and would sit off the runway in Okinawa and take pictures of the aircraft as they flew overhead. He would then go home and carve out models of these aircraft and sell them. After my father was released and informed he was to restrict his model purchases to the local base stores, the military then went to this man's shop..., purchased it and everything inside (including the man's photography equipment and all of his pictures) then paiud to have him and his family relocated to another part of the island far away from Kadena Air Base. Goes to show, the military and CIA do have a heart..., occasionally.
Hay, when you can solve a problem in a moral way that helps you to sleep at night? You do it.
Fantastic story. Thanks for sharing it! 👍
I love reading the comment section for hidden gems like this, thank you for sharing bud
"relocated" yeah, 50 miles off shore with concrete shoes on!
Well goes to show that the Civil Engineer did a better job of counter intelligence than the CIA did on that front, and restricting his model purchases from the beginning would mean that he would never have caught the "leak" and many wasted hours looking inside the camp when some random passer by who made models was the unwitting leak ... people see unknown things in the sky, people take pictures, if they have the skill they remake them .... its how humans have made money for millenia, and seems to be a weakness in intelligence thinking at that point

I just learned today, because of this video, that the plane I got to sit in as a kid was not an SR-71 but an A-12 Archangel......mind blown.....this has rekindled my dream of flying a plane....😎
"Archangel" - Best weapon name ever!
My step dad Carl, was the lead engineer for the engine at Pratt and Whitney aircraft for the SR-71 back in Connecticut. He is 95 years next month. Lots of memories for him.
@_SilverArrow_xxx I did, thanks! He actually was the engineer who solved the problem of the over-heating of the air inlet (RAM effect, he said) where the seals and solder on the electrical components would melt at over mach 3 from friction. They didn't want to use water coolant and another tank, so he had the idea to use the fuel to pass through the inlet housing. It had three positive effects: less weight with no additional coolant tank/pump, saved needing to enlarge the plane and pre-heated the fuel for burning efficiency.
Simon I have to say that I'm actually really impressed by this video. I'm a pretty enthusiastic aerospace enthusiast (and am studying for an aerospace engineering degree) and usually channels like this are great, but aren't ground breaking for myself as I usually have heard about a lot of this stuff. But I actually learned quite a bit of stuff this video, so major kudos to you and the research you and your team have done, it's always been top quality in any of your channels.
Kudos to you. I did ME for 4 semesters before changing my major back to EE and just taking a minor in ME. Fluids was a bitch... I'd rather count electrons than calculate the pressures a fluid excepts on a wonky geometry.

Although I love the A-12 for it's incredible history and performance, I also have a family connection which I am very fond of. My dad worked for the CIA at Groom Lake when the A-12s were being tested there. He was part of the security team, and one of his interesting stories is about how he got hired by the CIA to begin with. Oddly enough, it all started with answering an ad in the newspaper, and he didn't even know what the job was until he was hired. During this time, he, my mom, and I lived in Las Vegas, where I was born. Every week he would go to the airport and get on a military plane (later they started using Janus Airlines) to fly to Area 51. He'd work there for the week, and at the end of the week he'd be flown back home again. I never get tired of asking him questions about his time there, and he remembers it fondly.
Well did he see any thing like ufo or Bigfoot???
@@dallasjelinek6432 No, only the beautiful, shiny, Lockheed A12 aircraft he was charged with keeping a secret at the time. :)
I, as one, know that when the A-12, or the SR-71 took off the first thing they did was fuel-up and then go into afterburner and get upstairs as fast as possible, and once they went into afterburner they stayed in afterburner. The way the J-58 engine was setup was that once you went into afterburner you stayed their, because your engine converted into a ramjet engine, your speed stayed right at Mach 3.2 or so and your fuel economy stayed good. You can look it up if you want. One remarkable aircraft. Michael said that. Bye for now my friend.
I heard from a friend the SR-71 fuel tanks were designed to expand with the skin of the aircraft and seal completely when heated by supersonic friction. Before getting up to operating temperature the tanks would leak, which was why they refueled in mid-air after takeoff.
That is a ballsy way to deal with fuel leaks!
@@firstmkb I agree the fuel tanks are integral to the aircraft structure. The highest temperature occurs in the outer edges of the aircraft-they are trimmed with composite materials like the Space shuttle. Fuel is used to cool the aircraft and balance the Pitch (AOA).
@UCYyt9WQ9FZXGrgZBIpF_3KA I, as one, am not willing to argue the point of weather or not the A-12 and or the SR-71 had afterburners, It seems to me that if you are capable of writing in these comments....then for sure you are capable of looking that information up for yourself!!!! And if it's any good for you I'm going on 79 year's myself. But if I feel like making a comment about something I, as one, make DAMN SURE THAT I KNOW WHAT I'M TALKING ABOUT!!!! Michael said that. Bye for now my friend
Have read stories from pilots that claimed to be far over the top speed declared for brief moments. The limit is susposed to be the windscreen temperature limits.
@@firstmkb The SR71 also used a specialized jet fuel named JP7 which was specifically designed to have extremely low volatility, low vapor pressure, and high oxidation stability, all meaning that it's extremely hard to ignite. The stuff was so unwilling to ignite that every single time that the engines were started or went into afterburner they had to shoot an extremely volatile hypergolic chemical called Triethylborane into each engine in order to ignite the fuel. The airplane was incredibly fuel efficient once it got above about Mach 2.2 because above those speeds the engines would transition from functioning like normal turbojets to functioning as ramjets, the SR-71's had a fleet of tankers in the air wherever they needed while they were on mission, the only thing that gave them a hard limit in terms of mission length was the limited amount of Triethylborance (TEB) charges they had.
Kelly Johnson Lockheed Engineer.. A aviation design extraordinaire..One of the greats!!
Both planes were designed to cruise in afterburner all the time. In fact the faster they flew the less fuel they used. The afterburner contributed the majority of the thrust at Mach 3+. In fact the engine ran as basically a ramjet with the inlets fully forward.
I think this video missed a lot on their engines to be honest. They are the most interesting part of the a12.
At speed, the intakes provided over 60% of the aircraft's thrust. I don't know how that works, to be honest, but none other than Ben Rich, the lead engineer who designed the intakes, confirmed this to be true in his book "Skunk Works: A Personal Memoir of My Years at Lockheed".
The improvement in fuel burn was mainly due to the intakes also, from what I've read. Of course, higher speed required a higher fuel burn rate (the laws of physics being what they are), but the burn rate per pound of thrust went down, as did the burn rate per mile. Those intakes were pretty friggin' amazing.
@@ztoob8898 I think its literally pulling in so much air that its pulling the plane forward.
@@ztoob8898 it uses compression forces according to Bernoulli's principle for air compression being negligible at lower velocities, but inversely more important at higher velocities. The more you can slow down an extremely fast gas, the more it will increase in pressure at supersonic speeds. The engine adjusts for compression ratios at supersonic speeds to maintain an increasing thrust.
So yeah, it kinda just pulls air in to move it forward using physics.
@@autisonm The J58 is a Turbo Ramjet. At High mach, the spike does the majority of the work compressing the air which is then bypassed around the main engine (compressor,combustion chamber and turbine assy) and into the afterburner section. This makes the afterburner way more efficient because this highly compressed air is unburnt thus having more oxygen. So in reality the afterburner is used constantly at high mach numbers, but it's not technically an afterburner at this point (because the majority of air is unburnt when it enters) just a large combustion chamber. The main Engine at this point is providing approx 20% of thrust
It can be a difficult concept - I used to work on fighter engines, and understand supersonic intakes (shockwave and pressure reversions etc) mainly it's just witchcraft
But basically what you're trying to do all the way through an engine is manage pressure and velocity - As Pressure increases so does temperature and velocity decreases - if you restrict the air then velocity increases and pressure/ temp decrease. Put your thumb over a hose pipe - high pressure behind your thumb with water slowing down - past the restriction low pressure and water velocity increases.
@@bencolbert6732 At supersonic speeds each inlet swallowed 100,000 cubic feet of air per second, the equivalent of two million people inhaling in unison. Once the engines are increased to military power, their rpm's and the air, flowing through them, remain constant. The inlet guide vanes on the face of the compressor will have rotated from the axial to their cambered positions, at speeds around 1.7 to 2.3 Mach. The engine is providing all of the thrust that it can produce, 17 % of the total thrust at Mach 3.2, with the inlet producing 54 % and the ejector 29 %. The face of the compressor actually has a slight negative thrust on the aircraft. The spike and shaping of the inlets provided an astounding 84 % propulsion efficiency, which was 20 % more than any other supersonic propulsion system ever built.

As an aviation addict, you caught me totally off guard with A12. I too like you have seen the SR71 in person.

I believe you can see an A-12 in person aboard the USS Intrepid in NYC.
There was a third variant: The YF-12A.
The SR-71 replaced the A-12 because it was more advanced. It could carry more fuel, more payload, and a second crew member. It also developed more lift had a smaller radar cross section, thanks in part to the chines.
Wasn't the A-12 the initial CIA variant and the SR-71 was for the actual military?

On most aircraft, the afterburners are used infrequently. The Concorde, for example, flew in "supercruise" which is the term for mach+ flight without afterburner. But the SR-71 and the A-12 were designed to cruise in afterburner. The engine's core was primarily an air pump to feed fresh oxygen to the afterburner. Once the aircraft neared mach 3, the inlets and ejectors provided most of the thrust, the afterburners second, and the engine core a distant third. That's just the way it worked.
Clarence "Kelly" Johnson was a freaking genius.
A good friend of mine yes.
Was he though? The swept back wings come from German research and the Germans also developed a high-altitude spy plane in WW2, which was very, very similar to the basic design of the U-2. It's called the DFS 228. They benefitted quite a bit from captured German research. However, the Americans produced very innovative designs during the war as well and yes they also had great engineers. I am just saying that there is a lot of German technology in the post-war jets of the US. West Germany even developed a plane very similar to the F-117 before US pressure resulted in the cancellation of the project. Look up the MBB Lampyridae.
*Edit: And the design of the A-10 was heavily influenced by the "Unnamed" Junkers Ground Attack Aircraft. Hans-Ulrich Rudel was also an advisor to Fairchild-Republic.
@@generalripper7528 Yes he was and a very good friend of mine.
@@generalripper7528 The US had swept wings. You have oversimpliffied the entire process of both the design and manufacturing of these extraordinary aircraft. When they started this, titanium couldnt be formed. They invented everything necessary to form and machine titanium from scratch. That's like the full lifespan of an entire civilization in a year, by one team on one project.
If Johnson isn't a genius, then why have Archangel and Blackbird NEVER been surpaassed?
@@davidmyersretiredaerospace8038 Wow! Do you have any Kelly Johnson stories to tell?
The YF-12A, the long forgotten version that was between the A-12 and the SR-71
My shop teacher when I was in high school in the 1980's who served as a radar operator at a base in Vietnam during the war claimed that they tracked a SR-71 (I'm thinking it was an A-12) with an airspeed of 2,100 knots (2,400 mph). He said they were told not be tracking these planes on radar but I guess they decided to do it once. He said it was common knowledge on the base that the spy plane was capable of Mach 3.5.
Our FFG tracked both the Space Shuttle and S/R-71 once. Each appeared as ONE BLIP and was gone off our radar screen. If you blinked you missed it.

Used to live on Kadena, and we'd see these things fly overhead a few times a week. The plane is called the Habu over there.
Mostly unrelated, but I used to live near an Air Force base and saw a B-2 Spirit once, among the quietest planes I've ever seen (assuming similar altitude to the usual C-130s they flew out of there). Navy Hornets, OTOH, are so effing loud I'm surprised they ever hit a target. You can hear them coming for miles and miles.
HABU out of Kadena were SR 71’s

For those interested, 'Habu' is the name given to several pit-vipers native to the Ryukyu Islands.

why is drydock called drydock if it wet
Very interesting comparison of two great aircraft.
One small note: jet engine thrust is measured in pounds-force (lbf) not pound-feet (lb-ft). The latter are the units of torque.
I knew a mechanic who in the Air Force worked on the SR-71. He said the airplane was stressed tested to the equivalent of mach 7.
It was used as a testbed to develop technologies that were later needed during the development of the “Aurora” hypersonic aircraft in the 1980s, which is still classified but has been seen and heard by lots of people
To show how classified these planes were I was stationed an a northern base in the US when a SR-71 declared an in flight emergency and needed to land. Our base was chosen as the place to put it down. We had just a short time to prepare. The base scrambled to get 20 foot high curtains ready. They formed a 3 sided walls and when the plane landed it pulled into said curtains and shut off it's engine. A fourth wall went up behind it. NOBODY but the pilot was allowed inside. We placed 50 security forces around the plane but they were not allowed withing 75 feet of the curtains. By the end of the day we had a flock of C-130's land with security folks to replace ours, maintenance folks to work on the plane and 2 pilots to choose from for the return flight and they even brought their own fuel trucks (loaded with fuel) to refuel the plane. By the next afternoon the plane was fixed. Th rear curtain was dropped, the engines fired, the front curtain dropped and it's taxi was also it's run up to speed and it was off the ground in seconds and just a memory a few seconds later. This was what the folks on a US Air Force base go to see of this plane. Nothing unless you saw it land or take off. Ohh one more thing, if you were seen pointing a camera in it's direction all HELL would break loose. lol Just my $0.02
I grew up in Northern California. I had the luck to see SR-71s flying around every once in a while as a kid. Sometimes just a few thousand feet up over Sacramento. It was always a huge surprise, and I wondered what the hell was going on for it to be so far from Beale AFB, so low over a populated area.
Actually, they needed their own fuel trucks, because the SR-71 (and the A-12) burned JP-7, not JP-4 like everything else; I doubt any Air Force base except Beale kept JP-7 on hand.
@My Dude ?????????????
Not surprised this is the most viewed video. The development of Kelly Johnson and fast planes is one of the coolest things human has ever done, if such a thing can be quantified.
I got to watch the SR-71 out at Skunkworks in Palmdale when my dad worked for Lockheed. They are so so so so so so so soooooo loud. Such an amazing aircraft...BUILT WITH A SLIDE RULE.
slide rule - that is ignorant Chris.
Great and informative video ! I've only ever really heard much about the SR-71s as my dad worked around them back in the day; its nice to hear about what came before.
Suggestion: PanAm - Clippers and the giant flying boats of the 1930s. They were amazing machines, luxurious no less.
This video needed to be made ! Thank you ! My father was an F 4 fighter pilot in Vietnam and while stationed in Japan he was driving across base and part of the road crossed the back landing strip . He was off duty driving with my mother and brother and an airman guard left the security gate open and an A 12 landed right in front of them. Nobody had ever seen any plane like it before and my brother thought it was a UFO. My father even got a bit in hot water just for seeing it and he was sternly told he DID NOT see that plane and then told my mother and brother they did not see it either and never spoke of it again until recently.
I am also fascinated by skyscrapers . What if you did a comprehensive video about the evolution of all the world record skyscrapers leading up to Birj Khalifa and beyond? I would love that
In 1973-1974 I was stationed on Okinawa at Camp Hauge, the base was about a half mile from the end of the Kadena runway. We always knew when the Habu was getty ready to take off. Two tankers would take off ahead of it. I lost three coffee mugs to the SR-71, the vibrations were so great when SR-71 Habu took off and did its tail stand over us, the cup seemed to walk right off the edge of your desk falling to floor. That was frustrating, especially if you had not had your first cup of morning coffee yet.. It would be gone for a couple of hours the return. We would watch some F-4 Phantom fighters take of, so we knew we had a show coming up. Maybe a mile out you would see some red and white lights come on and the Phantoms would disappear into the clouds. When the Habu closed to within a quarter mile from or base, the Phantoms would try to ambush them. When the Phantoms dropped out of the clouds, the Habu's gears would come up, then they apparently got permission to leave the flight pattern. The nest thing that happened, the Phantoms, would drop in behind the Habu in a kill position. As the got over hear, the Habu would do a tail stand and nearly bust our windows. The Phantoms were already in burners, when everybody went ballistic, straight up sort of. It seemed like it only took a couple of minutes for the Habu to loose the Phantoms and they had to break of their pursuit, a couple of minutes later the Habu would be back in the landing pattern, ready to land. Used to have some super 8mm film of the Habu coming in for a landing. You could really feel the pressure in your chest as it took off over you, like the Habu did back in 1973-74.
I did not even know this plane existed till today. Yes, the U-2 and SR-71 I was aware of, even saw the SR-71 at the Air and Space Museum. Wow!
“…considering the speed of the plane, the codename Oxcart is just a little bit ironic.”
Which is in itself ironic. Which means we’re looking at the uniquely British phenomenon I call “recursive irony”... which is so ironic it’s been used as a cure for anemia in wartime emergencies...
We can only repeat the RELEASED top speed and altitude of these planes, which are astounding. The ACTUAL limits will never be known, but from first-hand accounts over the years, we're considerably more than the "official" records.
I was on Okinawa/Kadina with F106s in 1968 and to our knowledge the Blackbirds were SR71s. We knew of a previous version called the YF12 which was a squadron of interceptors. I also "heard" that the YF12s were reconfigured as SR71s. I did not know of the A-12.

I would like to see a video about GPS
Ahhh Navstar
Heck yes! I'd say GPS counts as a megaproject! The array of applications and just how reliant modern technology has become on it is incredible. It's so necessary for modern tech that there are 3 other separate world wide navigation systems built by other countries that don't trust the US and so created their own to ensure they have access to a GPS system. (Russia, China, and Europe all have their own systems) Plus Japan and India have their own regional positioning satellites (in geostationary orbit so the ground trace covers their respective countries) to make sure their countries are covered.
In Palmdale CA, there is an A12, SR71 Blackbird, U-2, and a D-21d drone(same engine of the SR71 I think) on display and it’s free. It’s called Blackbird Airpark. There is also another aviation museum next door. It has everything an aviation fan could ever want to see including a F104 starfighter. It’s also free. While driving there you drive through The Skunk Works. I drove 16 hours to get there and it was worth every second.
It would be interesting to hear about the Interceptor version of this family of planes the Yf-12.

How about one on the CN Tower, it was the tallest freestanding structure for like 30 years
I was pleased to have had an opportunity to visit the CIA headquarters in Langley, Virginia a few years ago to assist in delivering some original art for display at the CIA's private museum. I believe that the oil paintings of the A-12 that we delivered were the images seen in this interesting episode. That occasion was just prior the dedication of an A-12 that is now installed on a pedestal outside the rear of the CIA HQ building. We drove under the A-12 on the way out, but they were still finishing up the display area.. We also got a tour of the CIA Museum [closed to the public, with some display items viewable at the CIA Museum's www site] with the museum's Curator. All of the CIA brass and a number of very senior military people were present during our visit, as it coincided with the Director's annual Christmas party for employees. We were supposed to get our picture taken standing next to the big CIA seal on the floor of the building's entrance area, but unfortunately the CIA's official photographer was busy at the Christmas party, and use of our own cameras was prohibited inside the property. It was a very fun and interesting experience.
6:37 "...at an altitude of 6 meters.." THAT would have been an interesting flyby....
For real. For our U.S. persons that's only 19 feet off the ground. Might be cool to see though. (from a distance) :)
It was not a flyby it was a take off with the landing gear staying out. The landing gear apparently created instability and the pilot decided to land on the salt flat instead of risking a turn.
Definitely would have needed an extra pair of undies and pants for sure....!

@Generous Principle lol
For a more in depth history of A-12 Oxcart/Archangel I would highly recommend Annie Jacobson's "Area 51: An Uncensored History of America's Top Secret Military Base". There is a lot more in there other than just the A-12 but since the A-12, and the U-2 before that, is so closely connected to the building and development of the Groom Lake base it covers the A-12 history extensively.
This video brought back so many vivid memories for me. The cosmic top-secret projects are very alluring, but to those who live with the memory of them, it can take decades to stop having nightmares. 50 years ago I served in the black area where the SR-71 Blackbird was maintained underground and rose on an elevator before taking off in mere seconds.
Interesting what Mr White shared. I'm only aware of the -71 operating out of Kadena and Edwards Air Force bases. Now, someone several years ago told me he saw a TR-3B come out of an underground storage at Edwards, rotate slowly and then instantly was gone.
> Mr White, if you ever read this reply, what can you share about other black projects?
@@brianjob3018 The Blackbird was the most awesome of all possible thrills to witness as it emerged silently from underground in the black area of Kadena AFB during my tour there. Jimi Hendrix had just recent died, and soon after I found myself on what we called "the Rock." I worked mostly the grave shift while stationed there, and what went on after dark caused me to have nightmares for several years afterward after my 4 years in the USAF ended. It was after I was discharged (honorably) that I realized how much background research was done to check out my friends and family back home in order to have a top-secret security clearance to be so close to the super-secret aircraft that could be used to deploy tactical nuclear weaponry, and perform high-altitude reconnaissance too. The technology that I saw being used over 50 years ago is still a century ahead of anything the day-to-day person has ever imagined yet. Lockheed was the next step, and I wanted no part in whatever was going on back then, so I declined their offer to come work for them. The experimental particle beam weapons I saw in 1969 were pretty to see at night, but my conscience compelled me to stay away from all of it no matter what the financial reward might be. The Space Force has existed for decades, and now the public is hearing about it.
The A-12 was also equipped with air-to-air missiles.
One measure of the spectacular technological success of the A-12 and SR-71 is that 50 years later, no plane has been produced that even matches, much less exceeds, their performance.
Actually the A-12 that the CIA flew in 1967 and 1968 in SEA did not carry any missiles, only cameras. It's brother, the YF-12A, which initially set the speed records was designed to carry a precursor to the AIM-54 Phoenix, which was the AIM-47 Falcon...Initially the A-12s that flew in mid 1962 were equipped with J75s because the J58s were still having teething problems after 4 years of development. By 1963 all the A-12s had been re-equipped or built with J58s. The J58 was NOT a ramjet..... it was an after burning turbojet with a bypass that overcame aerodynamic issues with the engines flying at speeds over MACH 2.5. This bypass principle was later used on the big fan jets we see today on most jets... especially airliner engines..
While they are spectacular, I guess there is not much need for that specific capability. It's very expensive to develop, not fault proof, can still be shot down.
And then there are spy satellites nowadays which can provide very precise picture. In a sense, they are the logical next step. Much faster and higher. ;)
I've heard the SR-72 is actually undergoing testing right now, and is able to hit Mach 6+.

"pretty excellent at reflecting radar"? That is exactly what you DON'T want a stealthy aircraft to do. Either absorb or deflect away, but if you're deflecting; you have to be careful in which direction you are doing so.
I think that's what he meant.
how do they deflect it though? is it something in the material its made out of or special tech on the aircraft itself?
@@YannisG784 Yes, everything; from the choice of material to the way they structure the material, angle of the surfaces, the paint they coat the body in, the way they position the air intakes for the jet engine (compressor fan face is a MAJOR radar cross-section).
As an example when we had a type of a ship in the navy, switching the round hand railing for a square handrailing with one of the edges pointing sideways made a huge difference for the radar cross-section like this; , as the radar bounced more either up in the air or down into the water.

The plane shown in the still photo at 17:22 is actually the YF-12, another cousin in the family. It was the only two-seater of the group. This plane never went into production.
"if you want to make some money, move near area 51 and wait for things to fall out of the sky"
I spent part of my childhood near Beale Air Force Base in California and I regularly got the privilege to watch the SR-71 fly, even getting close to it sitting on the tarmac during airshows (cordoned off with guards, of course).
There is an A-12 inside the museum in Mobile Alabama. I thought it was a Blackbird till I was 20ft from it and saw the single canopy. Very interesting storyboard next to it as well.
Ben Rich, the leader of the Skunkworks after Kelly Johnson retired, wrote an excellent book about his time at the Skunkworks that includes the development of the U-2 and the SR-71.
Higher than the SR-71? They must have had it smoking some really strong stuff!
95,000 feet was the maximum altitude that they would admit to. You should take the accuracy of the flight model with a significant quantity of salt, but in 'Chuck Yeager's Advanced Flight Trainer' (the last word changed from 'Simulator' due to a dispute with Microsoft over 'Flight Simulator') from Electronic Arts, it was possible, with a considerable amount of care, to get the SR-71 modeled in the game up to around 130,000 feet, although keeping it in level flight at that altitude was a question of 'how fast do you make a mistake and lose it?'
At around 12:20, you describe the afterburners of the A-12 being "used for takeoff and evasive maneuvers". They were indeed used for takeoff, but they were LEFT ON the whole time they were aloft. The A-12 and Blackbird were designed to run continuously on afterburner - not just for takeoff. Indeed they were most efficient at top speed/full afterburner. As for evasive maneuvers, all the planes had to do was go faster or move the stick a little.
This channel is what the History channel used to be. I love it.
One day there'll be nothing left of Simon except a massive beard.
All this plane had for defensive measures was the Throttle.
Impressive way to elude air to air missiles....just out run them.

To give you an idea how fast Mach 3 is...its literally faster than a bullet
Later variants also had a jamming pod in the tail that could confuse missile tracking gear as well. It was code named Oscar Sierra but was nicknamed "Oh S____" by the pilots because that was their reaction when it came to life.
@ I think that for the SA-2 Guideline SAM, the A-12 operating at upwards of 95,000 FT, altitude was the main defeating factor, not speed. Years after the -12 was retired, North Korea launched an SA-5 Gamon at a -71 and it exploded at about the same altitude and about a kilometer or two behind. I believe that was the closest call the -71 ever had.
@ Simply put, I'm going to maintain that the SA-2 was not effective past 80,000 ft but the SA-5 clearly was. The mach 3 speed of our planes was definitely a complicating factor for the missles. I can't comment on fuel limitations. Please do your own research into the exact capabilities of the Soviet-designed SAMs operational when the A-12 was operational.
it was a good strategy, until the missiles could catch up to them. Same energy with us pursuing stealth.
Build a fast plane = my missile is faster
Build an invisible plane = this radar is about to ruin your whole career
Imagine the amount of money spent to make something faster/stealthier, and "I spent less than you on a gadget that makes your stuff obsolete".
At 12:29 you mentioned that the afterburner was used for takeoff and periodically when needed.
This is true, but the J-58 engine was designed to operate continuously in afterburner.
It's basically a combination between a turbojet engine and a pulsejet engine. Crazy unique design, and between the disparency between the claimed, estimated top speed, and the actual records the Blackbird holds, I'd say we, the general public, do not know what that aircraft's actual top speed is, because it gains power as it goes faster. I'd reckon the nosecone's ability to tune out the shockwave would be the only thing stopping it.

I did some contract work for Lockheed back in 99-00. I worked out of Ft.Worth but was shuttled to Marietta for a month, and shortly before my contract was up, I was sent to Lockheed's Palmdale facility. At that time... they had an SR-71 parked at each corner of the base and an F-117 on a pylon at the main facility. Gained a new perspective on "first impressions" that week.
It was less than a week spent there, but I saw some wild stuff. Examples... I saw the JSF-C (F-35) prototype/test bed without its skins, awaiting completion and testing, saw (at that time) Northrop's next-gen lifting body space shuttle replacement in a rented hangar on site (spooky... half finished, full size, just standing up in the dark in this huge hangar) and I was able to attend an informational briefing from an F-22 test pilot (F22 was still in proving phase) and his stories were mysterious, entertaining and at times jaw-dropping. Helluva plane, from what I could gather. Didn't even get "the whole picture" of what the plane could do, and I remember thinking... "boy, it would really suck to meet one of those coming the other way." And that was 20 years ago... Knowing what I know now... with the advancements of the program... A half dozen Raptors would lay down one serious "sh!t show" for the enemy for hundreds of miles in all directions (in the air).
I'm no aviation expert. Not a pilot (aside from a couple dozen hours in a twin engine prop). I was simply crossing paths with the industry and had a true passion for military hardware - still do). Was in my my late 20s. Was a pretty fantastic several years of my career. --- Good video. Thanks for doing this. Enjoyed it.
"as much as spyplanes become household names"
There was another variant of the A-12 that continued to fly into the late 1970's. It was the YF-12c. Someone got the crazy idea to try to make a fighter out of an A-12 but apparently didn't consider that the plane could literally out fly much of it's ordinance. I actually had the opportunity to very briefly see the only remaining YF-12 while on a tour at Edwards AFB with my high school ROTC unit in or around 1977. They had it sitting in a hangar with armed guards at the hangar doors. After pointing the aircraft out to the public information officer we were told that it must've been a SR-71 as our AF bus immediately started speeding out of the area. Go figure....
The classified information on the SR-71 is mind blowing stuff! I wish that since they retired the SR-71, they could release it’s mastery of the sky. People who have seen it fly, like I have , know it is still the best thing ever to have flown!
You're close, but not quite right.
The YF-12A was a preproduction design for a high speed _interceptor_ (not a fighter) - three airframes were built, flown and tested. The production version was to have been called the F-12B, but the program was cancelled before any were built.
There was never a YF-12C - That was a fictitious designation applied to NASA's SR-71 to help keep it secret.
I've encountered this idea that the plane could "out fly much of its ordinance," before but I'm baffled as to where it comes from - The YF-12A carried only one weapons system, the AIM-47 Falcon (also known under other designations such as GAR-9), a predecessor of the US Navy's AIM-54 Phoenix, and those things *_definitely_* go faster than anything in the Blackbird family.
If anyone is interested in aircraft like the A-12 and the U-2, I highly recommend the book Skunk Works by Ben Rich.
The U-2 gets shit on by the SR-71 Blackbird.
The story of the A-12 "Oxcart" was mentioned by President Johnson in the early 1960s. It became declassified in the early 1970s as I read about the YF-12a and its related versions, the D-21, in 1972.
The A-12 or its predecessor that looks just like it was already flying out of Kadena Air Base in Okinawa in 1959. Therefore it was most likely the CIA version that was highly classified. I don’t know what their designation for it was. It looks exactly like the A-12 or the SR-71 blackbird but I saw it at Kadena Air Base in 1959. They would bring it out of a remote hangar at dusk and it would take off on its mission. I don’t know why after all these years they still say it was built in the 60’s. There were no markings on it, just the flat black color. The people directing it were Air Force personnel or looked like it as they wore Air Force fatigues. Anyone else remember seeing it at Kadena in 1959 that would care to comment? I saw it from approximately 50 feet away on the other side of the security fence.
@@matthew1995king Not sure what you mean, but the U-2 has a distinguished career, and continues to fly today. So far, that's 64 years of service.

When it comes to naming stuff, the military's creativity and pure badassery are unrivaled. You have Blackbird, Archangel, Valkyrie, Nighthawk, The Big Boy, Castle Bravo/Romeo/Yankee, Tsar Bomba, MOAB, Gat12 Gatling aka "The Crowd Pleaser" the list goes on...
All of which are great but then you get STRATOFORTRESS
I was lucky enough to see The SR 71 at a air show in England 37 years ago beautiful plane very loud,
👍
I was probably at that same airshow ... 1983 up near Redesdale, Otterburn if I remember correctly. There as part of an American Airborne contingent training with some of the SAS guys .... I remember the SR 71 well and even have pictures I took with a little Minolta Weathermatic 110. I just can't remember if we were in Otterburn that day or perhaps we were staging at the time preparing for a jump out of Alconbury. We were all over the place, so I can't be sure, but I have pics of the SR 71. It was the second one we had seen having seen one once before near Marsh AFB in California when we were preparing to return to Bragg after Gallant Eagle '82.
@ACF you're correct, they did leak oil when they were cold as they were made to heat-up and the tiles would expand at altitude and speed. I had it explained to me once and I cannot remember if it was part of an oil cooling system that leaked or what .... but they did leak when cold on the ground. I was fortunate enough to actually meet an A-12/ SR71 pilot, retired, in Memphis, TN in 1990. He had me up to his office even and showed me all of his memorabilia which included walls lined with pictures of the various jets he flew with him, et al, beside/inside them. And he told some pretty good stories. He's passed now but we stayed in touch for years afterwards.
I think he meant it figuratively not literally.
@@Hattonbank no, it wasn't figurative .... literally they leaked. As I explained, the bird was made to be flown fast and hot and its pieces would expand at speed and altitude (much like atmospheric reentry in a space capsule module) so that everything sealed tightly. On the ground, when cool, it would drip fluids.
@@GalloPazzesco Sorry, I think I inadvertently replied to you instead of Rylee when he replied to ACF saying that a Corvette engine would not fit into a Miata, ACF, I thought, was speaking figuratively.
I agree with you about fuel leakage when the aircraft was on the ground, and the friction of high speed expanding the metal to close the seams. Apologies for replying to the wrong person.
My dad pointed out once that the reason these planes’ top speed was classified is because they couldn’t actually find where they stopped accelerating before they’d rip apart from aerodynamic stress.
Meaning that the fastest air breathing plane ever never was never even able to reach its top speed.
Yes your dad is correct. Not an engineer myself but others here have spelt out that the A-12 would essential rip itself apart. So pilots were speed limited
This is actually true of most supersonic aircraft with variable geometry intake (the J58 installation is those mobile cones and trap doors; on F-15, those would be sloping ramps). As you gain speed and keep the oblique shock adapted, the pressure gradient in the intake gets larger, increasing thrust -- at such regime, the engines are just pumps to get rid of the air from the intake that is actually providing the propulsion. That is the reason the F-15 speed, for instance, is often described as "Mach 2.5+", since Mach 2.5 is not really the limit of what the propulsion system can deliver.
This is not as much "classified" as "never really tested".
Considering the heat at which titanium loses it's structural rigidity it's been estimated the top speed of the A-12 (or Blackbird) is around Mach 3.5 - 3.7 At that speed the heat generated by air friction would heat the metal to the point the plane would fail.
My Uncle who was an SR-71 pilot would only say Mach 3+, then smile...
@California Dreamin Yeah, he was very interesting indeed!
there was a Popular Science or Mechanic issue that detailed in great depth how SR=71 was developed and manufactured. It was almost impossible to build it.. It took lots of problem solving to make it fly. It was never enough to have just titanium, because many of the problems to be solved was related to high temperature that created problems . It was a fascinating issue! I was too cheap to buy the issue online if any..
I had the honor of watching a Sr-71 Landing at an airbase in Nj in the early 80's while on an cable car ride in Great adventure Nj. I know the air base, cant remember the name, Black, long, loud and you can not mistake the shape. It was awesome.
this thing is mind blowing to me today. Back then it must've seemed like it was sent back from the future.
That was because of one Kelly Johnson.
Amazing indeed, as it was designed and built by engineers using slide rules in that pre-computer era.
11:45 - I would love to see you do a Burj Khalifa video. Even if others have already done it, I like your style and would enjoy watching your version.
Gotta say the same. I don't actually care one bit about the Burj, but I let Simon tell me about circumcision earlier just because I like his channels.
My thoughts exactly
