Just made my day, hahahaha >v
Lol this comment is so underrated.
For a few seconds during startup, it sounds like one of those aztec death whistles.
This is the first comment and its great
@Sakkra101 And crap your pants.
Not only were the blade tips producing sonic booms constantly, the shock waves bouncing off the ground whilt it idled produced subsonic waves that did everything from inducing nausea to cracking glass and concrete.
6000 horsepower Allison XT40-A-1 I believe was used. I feel bad for the pilot he had to sit in that noisemaker and fly that thing
I've read that the pilot didn't actually have it as bad as the ground crew. Due to the supersonic propellars, the sonic waved were shot more outwards than at the pilot or something like that.
@@spicketspaghet7773 "As long as you stood ahead of or behind the airplane,” says Beaird, now 78 and flying Learjets, “it really wasn’t so bad, but if you got in the plane of the prop, it’d knock you down.” Really? “Really.”
@@Rutherford_Inchworm_III My grandfather was a cropduster and flew an Ayers Thrush Commander with a 600 hp radial that had a two-blade prop. It was awfully loud, even when taxiing. However, if you were standing behind it, you could barely hear it (you’d get a very good breeze though lol).
Gave a ground crew chief (I think) a seizure because of the pressure changes.
This would be terrifying at low altitude
massive in CAS, just a flyby might knock enemy temporarily out.
the american stuka but without the siren, just the sound of the propeller
Cancerous Not only would it be psychological warfare, it would also cause permanent hearing damage, severe distress and overloading of most of the senses, and may even cause seizures if the one story is true!

I want proper recorded sound, put the bastard in the air again! We need proper sound!
Considering the airplane flew less than 7 hours before being grounded forever, and that the first person to fly it refused to ever fly it again, saying "You're not big enough and there aren't enough of you to get me inside that cockpit." flying it again seems like a bad idea.

They don't have the balls to pilot it anymore
Not only did it make the ground crew sick, it supposedly made the pilot ill as well. So it probably couldn't use it as a weapon unless they trained a deaf pilot.
Or very very good noise cancelling headphones
blaster1 112 Sound waves would still effect the pilots body.
It induced a seizure in a crew cheif.
Or implement the engine to a UAV.
Deafness wouldnt stop the soundwaves from making him sick.
Have you ever been at a loud concert?
Have you ever felt incredible.high db sound rattle your ribcage, and make your stomach tingle?
All of you who've been to concerts, especially small venues where you're right by the speakers and subs, you all know what I'm talking about.
The pilot and ground crew experienced that sensation x100. THATS what made them sick.

@@dragonsword7370 loud and not proud. The sound of inefficient propellers.
Aaron Cabaniss it was extremely efficient for its time
DID YOU SAY SOMETHING???
Oh, how awesome it would be to have a proper sound/video of this machine. I believe only one remains in existence, and not even that one is in flyable condition, but the story goes that they were not very easy to fly, either. I still wonder how the sound of it alone could cause illness and seizures (among many other things).
I heard the plane could be heard from 30 miles away lol
The propellers emitted somewhere around 900 sonic booms a minute.
900 sonic booms per minute = 15 booms per second.
Using modern simulation software (finite element analysis), it is possible to synthesize sound from the harmonic vibrations of individual components of a model). Watch those videos of Kilowatt sub-woofer systems. They can make car windows shake and hair blow around.
If you ever happen to take a trip to Russia go see their bombers, the noise they produce has been described as skull crushing and able to drown out the turbines on jets
This aircraft was on display at Meadows Field in Bakersfield, Ca for many years. I loved to see it when I was a child. The story I heard is that the pilot made an emergency landing at Bakersfield and the Air Force never retrieved the aircraft. It wsas mounted on a pylon in front of the Meadows Field air terminal. In 1992 The Air Force took it back and put it in the National Museum of the U.S. Air Force since it is the only one in the world.
phlodel I saw it at the usaf museum, along with an XB-70
8 years and is still recommended to me. Great Job RUclips
Anyone here after watching the Dark Skies vid that didn't actually have the sound sample included?
Incredible noise, you can pretty much hear it trying to tear itself apart. Can't even imagine what it must have been like in the cockpit.
Was just discussing this plane with other '50s aircraft fans. Thanks for posting.
You know, if they'd made this into a remote piloted bomb or cruise missile . . . they could've really disrupted enemy readiness by just flying up and down the FLOT (Forward Line of Troops) at a hundred feet altitude. Sure, these disruptive missiles would get shot down, a few each day, (and we'd keep 'em coming, sending more out at night) but the wrecks would land on enemy positions with their intended task accomplished. The horrendous noise would keep the enemy awake, discombobulated, ruin his appetite, and make him hate his leaders for putting him underneath the hellish USAF device.
William Cox It would be a waste of needed resources.
William Cox Awesome idea though
The USAF had an even more wacky idea. Check out the Supersonic Low Altitude Missile. en.wikipedia.org/wiki/Supersonic_Low_Altitude_Missile
You get all of my interwebnets points today plus one chocolate biscuit for getting "discombobulated" into a comment thread. It's a fantastic word, isn't it?
@@restojon1 Agreed
"You aren't big enough and there aren't enough of you to get me in that thing again"
Lin Hendrix (Test Pilot) flew it once and refused to ever fly it again.
And when a 1950s test pilot says that about a plane, that's when you KNOW it's a deathtrap
I tried playing this "at its original volume", but I think my headphones need more power.
LOL
you need cheap earbuds and a big ass amp
Man, there isn't a speaker in the WORLD that can do a 1:1 with this sound.
And im willing to take that to the bank for one specific reason.
The monstrous noise from this plane comes from *shockwaves.*
And no speaker is capable of producing shockwaves. Only soundwaves. Cause speakers can't reverberate beyond the speed of sound.
At least, i don't think any can.
@@davecrupel2817 Bose: Challenge Accepted
@@davecrupel2817 Your comment has made me wonder if it's even possible to do that with some sort of mechanical speaker. I'm imagining a long tube with a speaker cone at one end which generates a pulse, and a series of transducers in the wall timed such that they coincide with, or just slightly lead, the oncoming wave. Presumably as long as you could keep cranking up the amplitude by adding progressively more energy, you would eventually transition into a shockwave?
We should have flown it into combat then
Russian Cockpits fill with piss and vomit
orcustrex would've been our equivalent of the Stuka siren
For it to break in the middle of the mission? Not really a good idea for the pilot !
The actual performance of the aircraft was quite poor however.
my thoughts exactly. but using it would be a different story altogether. i think the most you could do with it is fly it over an enemy city low enough to shatter windows and put a few cracks in the walls. that alone may not sound like it'd be doing much but after awhile it'd bug the shit out of your enemy
There is one aircraft that could be considered a close-second to the ‘Screech. The Antonov AN-70. Search, queue, & play. Amazing noise!
I wish they would flight this plane one more time for a HD audio recording.
Probably one of the creepiest planes in history.
Imagine hearing this over Vietnam
The aircraft wouldn't need weaponry, just fly low altitude and the shockwave would rip you apart 😂
What a crazy sounding aircraft was always interested in that thing thank you for the video
I can't even lie, the sound of that was that fucking terrifying, I could only imagine hearing it in person, or even flying the damn thing, it has so much torque it constantly wants to throw you into a barrel roll
I love the Polish Godzilla poster at the end
Whats up with the old Polish poster for Godzilla? :D
Thanks a lot for posting this! I've been trying to find some archive footage or a sound recording for ages and then someone puts one on RUclips.
I particular like the fact they could only persuade one company to make them the test propellers, I suspect the engineers at other companies simply couldn't stop laughing when they saw the design brief!
searched long for this cause I really wanted to know how this incredible machine sounds. So thanks for uploading :)
Hello 2012. Who knew the algorithm would bring me here.
Now imagine if someone made a guided missile that sounded like this
Thanks Gus
Gave me goosebumps
I heard someone call this the "industrial fuel to noise converter", and now I can't stop thinking about it.
I've seen the XF-84H a few times at the US Air Force Museum in Dayton, Ohio where it's on display. Apparently, it created quite a din when it ran but I wonder how it compares, decible-wise, with the Tu-95 Bear? Although the Bear's props are subsonic, they are huge (about 18 feet) and counter-rotate.
The TU-95 is definitely nowhere near as loud as the XF-84. The XF-84 is literally louder than anything you will hear today that has an afterburner so if you think those jets are loud as hell, be as this doesn’t fly anymore or else air shows would never be the same. The TU-95 is barely even louder than a T-6 which also has a supersonic prop but that is about as loud as a CF-18 hornet in full afterburner
@@SirensAndAlarmsOfNorthernIL The only thing remotely close to an XF-84 is probably a shuttle
shame there is none of these in flying condition + people mad enough to fly it, as it would have been so incredible to get a proper sound recording of this using modern equipment.
+peter990099 "Flying condition" Even in the 50s when they were being designed they weren't in flying condition.
Jimbobthebarbarian Not true
Beavs_gaming, he was joking
i'd be mad enough to do it but i also just used to be addicted to war thunder and not an actual pilot :((((
These would've been perfect for lowering the enemy's morale. Just hearing this sound could induce fear. Not only is it super effective at lowering the enemy's morale, it's also effective at lowering your own troop's morale
Sounds like it could be used as a formidable weapon without even leaving the ground!
I think it sounds pretty cool it’s got kind of a futuristic sound to it
Its the perfect sound for a terrifying movie.
I am an ark lore nerd but i learned so much here. To say this is perfect is an understatement
R.I.P headphone users
My hearts go out to them
it's not even loud unless you're choosing to go in at full volume or something lol

Imagine if we ever DID take this to war.
"The last screech they ever hear"
At 600mph, making 900 SBPS (Sonic Booms per second, thats literally how insanly fast this things props spun), youve have had all of 30 seconds to either hide or pray you can lead your shots fast enough.
A technological "Nightfury" with that sound.
Must have inspired Hawkwind - almost like the beginning of Silver Machine!
Finally, a sane comment :)))
One was on a pylon at Meadows Field airport in Bakersfield California. I was told the pilot was in distress and landed the aircraft in Bakersfield rather than fly the few minutes to Edwards Air Force Base. The Air force never retrieved the aircraft and it was put on display.
Thanks gus
The way the sound swells up made my neck tense up and thicken. If that thing would be at full volume, I’d have chucked up my breakfast
It just sounds like wind though ?
This recording is bad and has No Description or entailing what it’s doing Either flying by or Just Starting Up !?
1000 sonic booms per minute during ground ops. Very daring but for what it was, much was learned from it.
Damn, imagine having to hear that with your own ears.
Not only that, but it must have been deafening and terrible for the test pilot, who is right behind this killer of eardrums
Could you imagine how terrifying this would be if you heard a squadron of these things flying over in the middle of a war?
Nobody:
Babies at night:
during ground manuvers like taxi-ing, start up, or full power run ups they said it so noisey that it made people sick so i see noise as just 1 of the reason this project was scrapped. the speed of sound is around 670-730mph if im not mistaken, and if the prop blades broke the mach 1 barrier while on low power, how fast would they be movin when the engine is at full throttle
Ooo some real ASMR here!
Thunderscreech would be a badass decepticon
Imagine hearing a whole squadron of these just coming towards you
I wonder who made this, first started it up, and was like, "yeah, this is a good idea, lets keep testing it".
Holy cow!! Wow!!
Imagine playing this in movie theaters instead of the Dolby sound 😆
What I would give to be able to pilot this absolutely amazing piece of engineering
It was very difficult and dangerous to fly, not just insanely loud.
They say no recording could truly capture the sound of the Thunderscreech, because the it wasn't the level of noise you could hear, but the level of noise that made you internal organs vibrate as if trying to violently escape from your rib cage
Get it out of the museum and drone it! We need the latest capture gear to record it. :D
Jesus, was this the darn thing starting up? Or taking off!?
Needs more Cowbell
call the cops
That jet was crazy.😳
The propeller blades are moving at supersonic speeds. Apparently this occurred even when the plane was idling on the ground, causing injuries to ground crews.
F/A-18 Hornet : I'M THE LOUDEST PLANE EVER
XF-84H : *oh please*
F-35 is louder than the F/A-18 lmao
pretty rare recording. i was always curious as to what it sounded like after reading about it. it is indeed a super noisy aircraft. hehe this noise could be used as a weapon :P
Why is there a Godzilla poster with Polish subtitles at the ending?
I wonder... with noise cancelation technology and remote control abilities could this plane have new uses today?
Never got past testing but I imagine it would've made a great psychological weapon
imagine a plane so loud that earplugs are completely ineffective when it comes to cancelling out the noise. kind of terrifying
Not just that. Even double hearing protection won’t do shit bc you would just get battered by the shockwaves if you stand facing the side of the prop. Heck, you would be fine wearing earplugs standing next to a jet going full afterburner but if you stood near this at full throttle at about 100 feet, the noise would most likely kill you
Imagine hearing this roaring over the jungles towards you
"Heyyyy, so uhm.. how was your test flight like?"
*_"WHAT"_*
This was a synth sound clip. The Republic XF-84H might sound closer to one engine of the Russian Tu-95 "Bear" bomber, as its prop tips break the sound barrier in flight.
I don't know why I never thought of this before but flying several of these at night over enemy territory would bean incredible psychological terror weapon.
Reminds me of the Junkers Ju-88 Stuka, with the sound that it makes when dive bombing, except for the fact that this thing doesn't need to dive bomb to make people literally shit themselves.
Perfect non lethal weapon!
Bring this aircraft to War - The enemies would die listening XF84H Thunderscreech sound at low level
Time keeps on slippin.....into the future 🤯🤣
Even the sound in this recording could drive you mad
If it weren't for the crew and pilot basically getting incapacitated just by standing next to this thing, it would be on another level when it comes to the psychological terror a soldier would feel if it flew straight at him... It's as if you can hear death himself coming straight for you...
This thing could have been used as a soundwave weapon device.
sounds like sizzling bacon filmed on the worlds first tape recorder or something
Imagine if they remade it and tested it for further information?like holy
Kinda creepy sound. Perfect to intimidate the enemy and mercinary.
Imagine hearing this at the middle of the night I would shit my pants
this plane doesn't need weapons against ground troops, its noise is enough weapon for it
You can always tell an xf-84 pilot. You just can’t tell them much
Was it the sound itself or the soundwaves that affected the pilot & crew? If someone had very good noise-cancellation headphones or was deaf (not they’d have a deaf person as a crewman), would they not be affected?
It has little to do with the ears , when the props go supersonic its a resonance , it is high frequency vibration that shakes your organs, si even a deaf person would get sick of thunderscreech, i wonder how the pilot felt that flew this as this resonance must be felt through the whole plane
Makes an MU-2 sound like a whisper. Damn I hated working around MU-2’s
Damn that sounds scary. I'm surprised this plane was louder than a fighter jet in afterburner. Was this the only sound recording of it? And was this on the ramp or flying?
Duderocks5539 well the reason it’s louder is due to the fact that different areas of a propeller were breaking the sound barrier multiple times a second. It’s really technical and takes a long time to explain, but this plane is driven by a turbine engine coupled to a supersonic propeller.

This is not the actual sound, someone made this with their synth.
Low bit rate and signal saturation means even the real thing would sound like this.
Obviously someone doesn't know what a turbo prop sounds like
How you know?
However, today it must be possible of reconstruct the kind of sound and simulate how it sounded from different angles etc
The blades were going over Mach 1, it’s not that hard to imagine this is what it sounded like.
The first thirty seconds of this one sounds more realistic. ruclips.net/video/46oSEQocTsQ/видео.html
Now this is the Flying War Crime.
Is that the sound it made on the ground?
scary part was it was proposed for a carrier based fighter, so it would be like the stuka sirens but worse
Whats the source of this audio?
They should develop a drone version of this, and get a proper audio recording of how this evil plane really sounds like.
+Derek Wall - And what would be the benefit of the prop spinning faster?
Okay,i'm not a physics expert,but there is one potential use for an even faster prop. If the US Military wanted to use something like this in the form of modern UAV as an acoustic weapon, if the blades had a higher RPM,it would(in theory) cause more area of the propeller blades to become supersonic and therefore possibly become even louder and even more excruciatingly painful to the people its used against than the original XF-84h.
Granted in order to prevent it from literally destroying peoples eardrums,windows and everything around it, The throttle would have to be able to drop the propeller below supersonic speeds during takeoff then be able to run it up to a higher mach when in the air. Just my .02
More speed = more air being handled in the same time = more speed. (And a lot more fuel, consumption of which goes up as the square of the speed...)
Keith M I don't really think this would be of any use as an acoustic weapon. Sonic boom intensity at a distance is very much dependent on object size, and even a large propeller is small compared to any airplane so you'd have a weaker boom than the usual fighter. Besides, the (single) boom would happen only once, as the airplane passed more or less overhead. It would have to turn around and return to deploy subsequent booms, by which time anti-air artillery would surely be pointing at it.
This is true,however here is the catch. There is not just one sonic boom, but multiple booms per second due to the propeller blades,not the aircraft, moving above the speed of sound(Mach 1.18 or 901 MPH) generating a sonic boom with each propeller turn,this is why the XF-84h had such an incredible noise level and could be heard from 22 miles away according to one of the members of the ground crew who said he could hear it from his home. He also noted that when the aircraft was run up to full power,it was even louder. One could only imagine the levels of pain endured by anyone within a few hundred yards at full power.
My theory was that if the aircraft was low enough(around five to six hundred feet perhaps), the rapid shock wave sonic booms and the incredibly painful and damaging noise level could act on enemy personnel below causing nausea,pain,seizures and absolute demoralization not unlike what the ground crew experienced. And if the prop were to spin even faster, the noise levels would be increased due to more area of the propeller blades becoming supersonic and could become not only painful,but damaging. The Human eardrum can burst at the 160-165dB level.
How could this be used as a weapon? simple. AC-130 Gunship crews are known to fly around in a circle above the enemy target to continue firing on the position, if an experienced pilot flying a modernized XF-84 type UAV with a supersonic prop could do the same thing, it could be fairly easy to not only demoralize enemies with the unbearable noise, but also interfere with communications among the enemy causing confusion and panic. Meanwhile friendly personnel can eliminate the now disoriented enemies. It's like having a gigantic automatic stun grenade in the sky.
The problem is that it can also disorient friendly personnel as sound doesn't discriminate between friend or foe and it was regarded by the flight crews that earplugs "made no difference" with the XF-84h and as you said, the massive radar signature of the aircraft would make it an easy target for anti- aircraft weaponry. The idea isn't perfect but again it was just that,an idea.
Once again,i do not to claim to be an expert on Physics,but from what i know and have seen from this interesting aircraft, that was my theory. Do i think it would work? with some tweaking perhaps. Do i believe the US would adopt such a weapon? No. My two cents.
I believe the flaw is in the small size of the propeller. I don't think it is large enough to make a huge impact on people on the ground. You see, there *are* propellers that can run with their tips at supersonic speeds (Cessna 210 and others) and their noise is annoying to be sure, but not more than that. Since the intensity of the sonic boom is a function of the size of the object as well as distance, I don't see a propeller being a useful "stun" weapon. Interesting stuff, though, and good discussion!
Where did you even find this?
Couldn't they have weaponized the sound of the propellers to deter ground units?
Wow. It's so loud.
