- Remastered U.S Nuclear weapon testing moive by Atomic Tests Channel
Zuni is the first test of 3 stage device. Clean version using lead tamper, 85% fusion; Tewa is dirty version of same bomb. Design evolved into Mk-41, largest deployed US bomb.
Amazing that theres still new 70 year old atomic test footage still emerging.
Yeah
Theres a lot more out there that you don't know about as well... The amount of Cameras and angles each of these tests had would amaze you. Hundreds of thousands of hours of footage.
I can imagine what that must have actually been like to be right there seeing that go off and instantly feeling the heat from that distance and knowing how far away it was ( from the foreground antennas and tower ), I'd say at least 25-30 miles. I believe that was a relatively "clean" device but I am surprised it was detonated on an island in a "blockhouse". I thought it would have been on a barge.
The electronic diagnostic instrumentation must have been incredibly elaborate for the primary-secondary interstage timing measurement of instantaneous and delayed gamma ray emissions.
Freedom Of Information Act.
Not really, especially not if it was originally marked classified. That keeps it hidden for 50 years and once declassified it takes time for someone to even realise it's there.
I've used and worked in a lot of archives and often they arent as well organized as people think. Things can be forgotten or unnoticed for decades even though it's in plain sight.
That sequence from 1:54 must be the most awe inspiring, beautiful and downright scary shot i have ever seen. the quality and dynamic range is unbelievable.
I forgot it was dark out until the light started to fade. What an absolutely stunning shot.
Imagine Castle Bravo with that. It would have been bigger and scarier. This is incredible though.
I wonder how far away the camera was?
@@imtoostonedtocomeupwithaus5976 I'd love to know too! I'm going to guess 40 miles.
Im dying to find out this answer aswell...@@imtoostonedtocomeupwithaus5976
In 1963, at the Air Force weapons tech school, we had a Mk-41 case for practice loading in a B-52 bomb bay simulator. It was a big boy. There were other types of gravity bombs, nuclear rockets and a few, nuclear-capable aircraft to examine. From there I was assigned to a B-58 wing where I got to load the real ones. A very interesting experience for a 21 year old airman.
Wouldn't want the B.41 dropping on my foot!😁
The B58 "Hustler?" THAT'S impressive! The B58 was "the future with wings!"
Mk-41... that's the one that was 30 Megatons. And they made 500 of them.
Those were the doomsday weapons.
@@ibelieveingaming3562 Actually they were rated at 25 megatons for the "dirty" version with a U238 tamper, and ~10 for a "clean" version with a lead tamper. There were indeed 500 of them and they were part of the general nuclear stockpile until 1976. The Mk-41 was the most efficient yield to weight ratio warhead ever fielded. If war had actually happened in the late 50s or early 60s the amount of fallout on both sides would have been almost inconceivable.
@@Indrid__Cold ya know yer yields, grinning man.
Whenever I watch these, I'm always looking for a sense of scale. Haven't really seen anything that captures it quite as well as the 2:00 mark.
That shot looked to be quite zoomed in.
@@Deutritium93Yea unfortunately its the age old moon zoom trick. But 1:33 is a legit scale. Of course nothing beats having actually been there to see it. Sometimes during spring and summer I occasionally see those "thunder heads" rising up before a thunder storm hits and the scale of those I would imagine equates to a mt nuke. The awe affect would be witnessing the fireball climbing fast into the upper atmosphere while growing to ultimately end as another large cloud.
@@Deutritium93I sometimes see pileus clouds form above the peaks of cumulous clouds that resemble and act like wilson clouds but on a much slower scale.
ruclips.net/video/1f_LSanhxoU/видео.html gives you a great sense of how obscenely big the 50MT Tsar bomb fireball was. A 3.5MT fireball like this one would still be large enough to totally engulf the downtown area of any major city as it would be somewhere around 2 miles in diameter. It's still hard to get your head around.
@@Deutritium93 Ja, man mußte weit genug weg sein.
I have never seen this one before. Thanks. I ask myself why I have such a deep fascination of something so utterly terrifying.
You answered you own question.
These tests were all carried out at a time we weren't alive, when technology didn't give us ultra-clear footage, and you can't get a sense of scale from most footage. (Although this one at 2:00 is probably the best I've seen for that) It's natural to be curious about the sheer power of them and their immediate and downstream effects.
The footage of 1.5 mile underground texts shoving infrastructure and buildings eight feet up in the air gives a bit of an insight into the overwhelming power of them. The blast moved the entire weight of the earth above it so much that it made what was on top of it airborne. That's insane.
@@BlakearminI was alive then but I don't remember seeing any films of these nuclear test at the time,I guess if the government put that out there at the time I would have seen it at the theater when they ran the Movie tone news,or I think that's what it was called.
Most ppl do. For me it’s the Physics, Maths, IR/FP and Diplomacy, Military Policy and Doctrine with a dash of History
Me too
Because it is beautiful. Given the science behind it, the power and knowledge that mankind (best of it) managed to grasp - it is amazing. Those were the times people pushed the boundaries of knowledge, the power of atom.
Today, instead of building up on all of this knowledge, we build windmills and solar panels.
That's why these videos are so fascinating. A memory of the lost knowledge.
Love the films but people cannot truly appreciate the SCALE of these explosions.
Hard to put into your mindframe just how enormous they are
Wow! Using NUKEMAP by Alex Wellerstein a device of this size detonated above Indianapolis would leave an estimated 305,000 immediate fatalities and 515,000 injuries with approximately 1.5 million people within the blast range. Unbelievable
What's NUKEMAP?
@@beachlife4704An app created by Alex to simulate different sized "nukes" on places around the map. Pick a city, pick a size bomb and see the projected results. 338 million simulations since 2012
@@beachlife4704I answered this once but the RUclips algorithm removed it! It's an app to enter cities and size for a simulation. The word police are at it again
@@beachlife4704Search it on google you won’t regret it
@@beachlife4704 Es una página web en la que puedes probar distintas armas nucleares y ver sus efectos devastadores en el mapa de Google maps
Remember, this was daytime footage. The cameras have to be THAT blacked-out shielded just to get the details of the blast.
Watching this on my old Sony 55" XBR that I bought in 2008. Your footage is always awesome!! That cloud cover really gives it a different sense of AWE!! 😎👍
the camera blockhouses right at the beginning are so cool. All these weird mirror arrays and pipes feeding inside like a weird spiderweb, and knowing everything outside is going to get obliterated soon after
Old school diagnostics using many LOS pipes to carry the bombs first light and radiation to recording stations some distance away. Love it! Just one big open laboratory experiment(s).
Tee pipes were filled with helium (I think) so the light would reach it sooner than air, saving a few microseconds before being obliterated!
@@vandammesque Some were pumped down with a vacuum, some were filled with specialized gas, like helium. The X-rays produced in the first microseconds after triggering are opaque to air. The air absorbs these X-rays and the gas glows hot. So the light tubes use either a vacuum or a gas that is transparent to the X-rays they want to detect and measure.
:O WITNESS!!!!!!!!!!!!!!!!
The angle from the radio tower and carrier was easily the best!!!!
AMAZING RESTORATION! @Atomic Tests Channel!!!!!!
My great grandfather Alan witnessed this in person. He served in the navy during WW2 and Korea and after. This event is inscribed on his headstone.
The really interesting stuff happens in the first 100 microseconds.....After that everything is just coasting and chilling.
Yup, crazy, "not of this Earth" and literally off the scale gamma rays and some cosmic "rays" to boot ! And close to "Big Bang" temperatures if you can imagine it ! 😲 It IS absolutely incredible and fascinating that man conceived of such a thing !
And dying gradually
@@UNLTDvision Wouldn't it be nice if we had some real leadership in the WH who would deter this? there is a russian sub full of nukes parked in Cuba. So close there is no hope of intercepting the missiles.......
You have to remember when watching H-bomb footage compared to A-bomb films, that everything is roughly *_three_* orders of magnitude bigger!
Not 3x, but 1000x!
1000x more energetic, not bigger in physical size.
1000 times bigger in VOLUME, 10 times bigger in radius.@@lunacracy
@@giannismargaris9553 correct
Magnificent work. This channel is an absolutely vital repository of nuclear history.
Big Ol' Boy.......would be better without the dubbed sound, though. At 5 seconds per mile, it would take at least 45 seconds to reach even the closest cameras, and a few minutes to reach them all.
I’m curious to know how loud it would be at the camera?
Never mind the third-rate attempts at "dramatic" music that always seem to be dubbed onto nuke footage.
My understanding is that the immediate sound is electromagnetic radiation creating static in the microphone circuit. The sound of the shockwave is just "BOOM"
@@CheapButNotEasyand for sound from a few miles away prior to the blast wave and thus sound reaching us, it instead is reverberating through the earth like an earthquake. That is what happened in Beirut in 2020.
It's crazy to think that by the time your brain registers the flash the reaction is already over...
ATC, any idea what island the ground view from 1:53-2:08 was taken from? Heck of a perspective. Terrible. Awe Inspiring. Kiss your @$$ goodbye if ever a blast was seen from a comparable place.
I can feel the heat coming through my computer screen.
It wasn't zombies or monsters that frightened me as a child. It was THIS!
The zombies and monsters come afterword
And it still scares me as an adult. That crap should have never been discovered, by mankind. Its the most insidious poison on Earth...!!!
To watch this demon rise up to the sky in reality must be pure horror.
I remember in a nuke documentary from 1983, a retired service member who was present for the second nuke test after the end of WW2 said his greatest memory of that test was the light, and its ever-increasing intensity. It seemed from his perception that it wasn't going to stop, and that maybe that time there had been a mistake and it was heralding the end of the world.
And that was only the 20-kiloton Crossroads-Baker test. Imagine the flash from a test 175 times that size...or more, in the case of other, larger tests before and after this one shown here.
@@aloysiusbelisarius9992 The Baker test was the world's first radiological disaster.
@@JoeL-zb1yd Well, yes, this is true. They found out very quickly that water can make fallout even harder to clean up.
Good Day. A recently posted picture of the Trinity Test Explosion, showing the beginning of the explosion on top of the tower, just prior to the Disintegration of the rest of the tower is remarkable. I was born in 1952 and have seen Atomic/Nuclear tests, etc. all my life. I've never seen this remarkable photo before. I visited the Trinity Site on it's 50th Anniversary and stood where the tower once stood. A big item in a small "Bucket List" of items for me.
Thanks & Best Regards
1:54 Simplemente me quedo en silencio por las titanicas proporciones de la explosión.
You had to feel the heat even from that far away horrorable weapon
The Titan ICBM carried a 9 megaton warhead
They briefly fielded a 25MT gravity bomb. Boom.
These megaton class detonations are wild. Truly atmospheric level events.
1:54 oh my GOD that is insane… you imagine seeing one after another of those as the world ends? Nightmare fuel
What's really amazing is there are still people that say these things do not exist.
Who says that?
They would be correct about that particular one.
@@thatarseConspiracy theorist nuts, who also think the Earth is flat 🙄
@@ct92404 wow. Kinda sad these ppl exist… literally!!
The mind of a Magog
WTH is a magog?
The first true hydrogen bomb, not like the others before it that were merely boosted-fission bombs exponentially steroided. The majority of this one's overall yield was fusion, making it a true hydrogen bomb...though a simple swap of material for the tamper would turn it into a steroided boosted-fission bomb.
I'm surprised that this clip didn't show the actual BASSOON test-device as it is one of the few test-devices that have had their photographs declassified.
Given the embarrassment of riches we have of nuclear test bomb footage, it never ceases to disappoint me how the entertainment industry consistently gets nuclear bomb explosions wrong in their special effects.
Just beautiful footage. I never saw this one before. Great quality!
Beats me why they filmed through ship antennas.
AMAZING view from Eneu camera tower location (Station 20), looking toward WSW at 1:56
Also: the shot cabin view with the diagnostic collimator panels for streak cameras to evaluate the warhead coming apart in microseconds.
At :22 when the outline of the fireball becomes visible there are several glowing patches on the top of the fireball, the incandescent remains of the shot cabin?
@@emilkarpoThat’s the top of the plasma column inside the fireball, obscured by the refraction of the high density shock wave.
The plasma column rises extremely fast with the ground slap reflection of the blast, the lead of the mushroom cloud.
You see this glowing top from high airborne camera views of multimegaton surface tests
@@EK14MeV Thanks good points.
@@emilkarpo You’re welcome.
@@emilkarpo It’s fun to see the shot cab close up.
The two pipes the led from the cab were vacuum particle radiation tubes that led a long distance to a detectors instruments bunker designed to survive the mayhem.
Each pipe was to evaluate the particle energies performance of the fission primary and the fusion secondary over microseconds, recorded by cameras filming oscilloscopes. … Thus the two pipes.
The boxes and black panels were light channels directed by mirrors to measure the Teller light, the radiation glow around the weapon casing before and while the casings came apart and vaporized.
A critical measurement of weapon performance was the timings of the intensities of the glows isolated between the fission primary and fusion secondary, called the alpha timing.
The light channels were directed at heavily hardened photographic bunkers that used external mirrors to redirect the beams deep into the bunker where ultrafast streak cameras were housed.
Streak cameras measure the light intensity over extremely short intervals of time.
Therefore the difference in timing between the radiative glow over the primary fission device and secondary fusion are important for performance evaluation.
The black panels isolated the beams directed at the streak cameras at a remote camera bunker, from environmental light, called collimators.
Interesting "shrapnel" effect at the explosion and during the rising of the plasma ball. It seems a lot of blazing land material dropped/catapulted up to the atmosphere. Since it was a ground level test device (2m dry surface), it could be possible if the ecplosion itself excavated some island material, even if it was not an under-the-surface test.
In seconds there was a new Sun on Earth. Astonished by the power of the atom.
😂
What's so funny? One of those "nuclear weapons are a hoax" types?@charliejordansyoutubechann6857
I’ve seen people talking about 1:54 and 2:00, but why is nobody talking about 0:21?
Back then the US had bombs in the megatons. Today minuteman 3 has a yield of 10 times less than the explosion in this video
Good Day. Yes @john6137. Previous American Administrations greatly weekend our Offense/Defense posture by foolishly believing that the Soviets would actually abide by the nuclear reduction agreements that they signed.
"When We Build, They Build. When We STOP Building, They KEEP Building".
And, Today, The Russians KEEP Building and WE sit on our asses in denial of The Truth (There's that Word Again; TRUTH) and behave like foolish, stupid children for decades now, worrying about who uses which Bathroom and are a Completely Divided Nation that refuses to Pull Together As Americans Have Done Together In The Past, to Protect and Save Our Nation. There Hasn't Been Anyone "At The Helm" in our country for a very Long Time... America will get what America & Americans Deserve.
Peace? Best Wishes to us all.
The brightness and prolonged blast are unbelievable. Hard to believe it's"only" 3.5 megatons... It looks like the end of the world.
And to think they wanted a bomb almost 10 times more powerful! The Mk-41, the 25 megaton variant... And the 3 stage designs made this much easier.
Great restoration thanks for sharing
1:53 Hell unleashed
Wish we had camera distance information...everytime....anyway, thanks for the upload!
"Now I am become Death. The Destroyer of Worlds...."
Is all I can think of when I see this absolutely beautiful yet terrifying explosion-- something I wish will never be used.
There's so much of it I still have problems with understanding of the scale of these tests.
I would love if they could make a 4K remaster of the documentary Trinity and Beyond
Starting at 1:53 is absolutely insane
Yeah holy sh!t. Now that is a view. I always imagine viewing these explosions in relation to how close I live to our major city. Damn scary.
Yes, that was chilling. The heat and energy involved to make that massive fireball curl in on itself like that. Wow.
yeah its amazing
So utterly destructive, yet so beautiful too
It amazes me how they did these things, and so many of them, as if it was something to be very proud of.
I find that the logistics of setting up, the of moving men equipment leading up to each of these tests was staggering in itself, let alone the actual blast. My brother inlaw has a framed cirtificate for his participation in one of the "High Atmospheric Test"s done back in those days, i'll try to get a picture of it and post to my channel or whatever it's called.
The video with the burning palm trees that's often labeled as Castle Bravo, I believe was actually from Zuni. I think...
Awesome!
It's comforting isn't it to realize we don't have nuclear weapons these days
I always find the contrast of nuclear detonations to be surreal. I know what it is and how deadly and destructive it is but at the same time, they're so pretty.
I bet even from that far away that was still hot.
And not just thermally... The radiation levels spiked too.
I have never seen this Zuni footage before. There is the standard classic one that has been used over and over, but this had some different angles. Was that audio added in, or did they actually have some rare audio? It was ominous!!
I pray it never happens, but if it does, may ground zero be 1000 feet above my head.
I was just watching a video of a U.S. serviceman in Hiroshima with chalk and a tape measure marking out the shadows of people on the ground where they were standing in relation to the bomb when it went off. He was on a bridge, and you could see the shadow of the railing of the bridge in the pavement, and the camera panned back and you could see where all the people were... Shadows.
They really tested these weapons.. Watched it.. And thought.. "Hey lets build another 30,000 of these things, thats an awesome idea!".
Any normal person would be like "Lets agree to never do this ever again"
AWESOME !!!!
I wish they had the range of the cameras from ground zero at the bottom right corner.
Dr. Strangelove approves this RUclips video.
The beauty of destruction.
Too bad they stopped doing these great old megaton atmospheric H bomb tests. It'd be great to be able to book a three day vacation to go see one.
Maybe some day there will be trips to other planets where you can watch nukes go off like solar eclipse.
Unfortunately alot of these sound affects aren't the original sounds of the explosion.
Nice job again 👍 ... Btw, is there any explosion footage of so called "Suitcase nuclear device" ?
Yes, Davey Crocket test among others.
Upshot-Knothole Grable - Used the same physics package as the suitcase demolition device. This was a gun type design, very inefficient, and it was retired in favor of Swan miniaturized designs. The suitcase demolition device still exists, but all tests using the modern warhead design for this application were performed underground.
...that pillars of fire will raise the sky and you will know...
A Devastating Weapon but Strangely beautiful.
Fight War ☮️ Not Wars 🕊️♥️
What I learned: when you hear a roll of thunder that just goes on and on and on... better duck & cover!
This one really gives a sense of scale most others do not with some of the things in the foreground like that antenna. It has those same streaks rising up under the mushroom cap that bravo has. I always wonder what that is and I'm not talking about the smoke rockets. Maybe coral and other debris being blown and sucked up into the vortex
Looking forward to seeing this one
85% fusion just means 85% fission of the total fissionable material. the fusion stage releases neutrons into the fissionable material and accelerates the fission before annihilation. The fission would normally only occur in about 3 % of the plutonium before being vaporized and destroyed. old atomic bombs were wasting plutonium and dispersing unfissioned material, with only a small spark of fission able to take place. hydrogen bombs by dumping neutrons into a supercritical sphere accelerates exponentially the fission and allows for almost all of the material to have its fission. Any "fusion" that does occur in the hydrogen is not adding anything to the explosive yield itself, it just releases higher energy neutrons toward the plutonium, but the energy released by the actual hydrogen fusion is insignicant in the miliseconds that it's occuring.
the lithium-deuteride 6 is basically the only tamper you need - it doesnt "contain the neutrons" or reflect neutrons, its Adds neutron and Dumps neutrons into the plutonium. The use of a lead tamper or any other tamper is literally just stupid, it's only increasing the environmental damage and ensuring that a bunch of material does not contribute any energy to the yield.
Using a uranium tamper in the secondary can boost yield substantially, as U238 fissions in the presence of fast neutrons generated by fusion in the secondary. Might as well do that militarily, it does make the bomb nastier but also smaller at a given yield. Lead produces less nasty fallout. The high density of U makes for a very efficient tamper as well. The fusion in the boosted primary doesn't additional fusion yield. Fusion in the secondary is a major source of yield and generates huge numbers of fast neutrons to fission a uranium tamper.
@@CheapButNotEasy Fusion isnt a source of the yield - its the neutrons and fission it accelerates that boosts the yield. Without the hydrogen gain - only < 3% of the fissile material has fission before annihilation. With the hydrogen neutrons you're actually getting > 90% of the material to have fission. Non hydrogen bombs are only actually using a tiny fraction of the plutonium - its all waste. increasing that from 3% to 98% is the yield boost . The Fusion doesn't add to the explosive power - theres not enough hydrogen fusion taking place in that split second to add anything and if anything it is actually there to absorb heat and release neutrons - to reduce the yield of the first stage not increase it. But the neutrons it releases accelerates the fission in the second plutonium sphere allowing it to fission nearly the entire amount much faster htan the first stage would've. everything else is just scattered to the wind. Theres no point in adding more U238 as a tamper. The Tsar Bomba did away with the tamper entirely because the fusion stage *IS * the tamper... In fact its not entirely known how much fusion actually occurs, it may lead to faster neutrons - but even without fusing into helium the lithium-deuteride-6 also loses neutrons just from absorbing the heat and radiation alone - no fusion is even necessary for the increased yield you see in hydrogen bombs . If you have a hydrogen stage -- the yield of the hydrogen material not having any Fusion but only absorbing radiation and releasing neutrons -- and the hydrogen having 100% fusion in every atom --- the yield difference is not the game changer. The game changer is just getting 98% of the plutonium to have Fission. It's fission which is the releaser of all that heat and explosive power. It's fusion which Takes heat - and gives neutrons, light and helium as the product ---- not heat - which is the main thing you want in both Energy production and in bombs for yield boost -- but fusion doesnt release heat - it eats heat and releases a photon, neutrons, and a helium.
This is sick
Was that music score from Raiders of the Lost Ark, the angels of death scene?
And the Tsar Bomba is supposed to be about 16x bigger than THIS....
This always looks so amazing
So when you think about the 1961 Goldsboro B-52 crash ...
You will definitely get that beach bod tan at Bikini Atol.
How far were each cameras? It would help for a sense of scale
It's amazing how scientists went from Trinity to several orders of magnitude in energy output just seven years later ! Then this ! Physically much smaller and cheaper. I believe this was around 1956-57 ?
At 2:00 it looks like the camera is 24km away from the blast.
I like the rings that appear above the mushroom cloud
And what, that energy was made from 10 lbs of matter.
3.5MT = 162 grams = 5.71oz
(Mass-energy equivalence)
That burned a more than few kilograms of fissile material just to get that going, but actual mass lost was as stated above.
Yeah the amount of material fissioned/fused is obviously a lot more than the direct mass conversion. Zuni was 85% fusion, so most would be LiD.
This blast is 3.5 megatons. Had the Cold War gone hot around the time of the Cuban Missile Crisis, the Warsaw Pact would have vaporized many cities with such blasts- the standard short-range missile the Soviets had (aimed at every big city in Europe, and then based in Cuba as well) was the SS-4 missile whose warhead was 2.4 megatons.
Amazing top notch videos as always. Well done 😊
How close was this at 2 minute mark?
God help us if these things ever get used. 🙏♥️🙏♥️🙏♥️
Fantastic!
This is me in the morning when I've stopped at Taco Bell after a night of drinking
The bomb that created Bikini Bottom, SpongeBob and all his pals!
Is the sound actual or dubbed in to give dramatic effect?
Bigga, badda boom.
If the mushroom cloud is smaller than your thumb run for the hills, if not, don’t bother running at all.
you sure dont want to see one of those ?
Absolutely terrifying……
Like using a Pixel phone... you can erase everything and everyone you don't want in photo
Porqué pusiero el audio del Nostromo de Alien?
To think the French were still doing this in the 1990's
French pastries made'm do those.
Yes, but underground.... Npt atmospheric and we needed those last 5 or 6 tests to validate our own version of the national ignition facility based on the Megajoule Laser...
That was insane.
Now that the blasts have ended, weather has gone crazy.
As if the very elements themselves had been disturbed.
