Castle Bravo declassified
Вставка
- Опубліковано 23 жов 2024
- This film was declassified during the DoE's Film Declassification Program circa 1999 but is hard to come by and not listed anywhere. The video transfer is pretty bad so it was impossible to clean it up or improve it. Also, there is no sound as it has been removed to declassify it.

I have seen plenty of Castle Bravo shots, but I have never seen this footage before. Thank you for uploading, atomcentral.
"Let's drop Bravo on Tokyo."
"B...b...but Mr. President, the war is over!"
"You must be mistaking me for someone who doesn't hold grudges..."
the cement pillars contained mirrors that reflect and lift the image above the horizon for a camera aimed at them many miles away.
***** So, "AtomC", it was then hoped, that this ingenious "gimmick", might diminish the chance of holes being burned into the film, by the insanely bright light of the shot?
Swithin Barclay No, the point of the mirrors was to fight the curvature of the earth. Because the earth is round, when you are 20 miles or so from any ship or explosion, it appears to go under the horizon. The reason, early navigators thought ships were falling off the edge of the earth because they would appear to sink under the horizon. These pillars compensated for that and were up high enough so that the image the scientists wanted to see was not obscured by the curvature of the earth.
***** "Atom", thank you so much, for erasing some of my ignorance; however, I will display some MORE ignorance. It did look like those mirror towers, were smack dab close-in to the Shot Cab, where everything, and anything, would obviously be vaporized, in nanoseconds. Or, were they installed at the [Optical Proton] Instumentation Shack, a few miles away? I'd always thought that that Bravo Bad Boy had vaporized ANYTHING, within at least an Eight-Mile radius.
Hence, with all of this said, the Aircraft Footage of Bravo looks to have been the most reliable, for the Firing Teams/Parties, to take post-mortem measurements of, and, diagnostic observations of phenomena, from. Bravo, to me, does look quite beautiful to me, probably the prettiest of them all, with its ever-so-slow blooming of the Mushroom. I wonder, if there may yet still be more footage of Bravo, and, Ivy Mike, out there, awaiting discovery (especially Mike)?
I do wonder exactly how soon someone, or someones, began to realize that they had a "runaway" on their hands, with Bravo?
I did find a UA-cam clip, of a SOVIET UNDERWATER Shot, by the way, done in 1955, and, I kid you not, it looks almost identical to Crossroads Baker! The Shot was performed at the Novaya Zemlya Proving Grounds, shallow water, a few miles offshore. Towards the end of the clip, there's clods of shrapnel peppering the water close-in to the observation ship's bow, and based on that, I figure that the ambient seabed under ground Zero had to be quite shallow, as the Shot must have churned up the rock, sand, and silt, of the seabed, cooked it, agglomerated it, and tossed it up and out, of the fireball. I forget how to locate it here on UA-cam, but I shouldn't anticipate that you'll have too much difficulty locating it, yourselves.
Swithin Barclay the mirrors were intended to be close in to the cab. they were there to record the initial instants of the fireball. as soon as the fireball and shock front reached them they were destroyed but their mission had already been accomplished.
1:29 did he had a phone?
Even without sound, the new close-up footage of the bomb and test equipment is most welcome. Thanks.
there is audio in the 2nd half of the video
Weird that there wasn't Audio for most of Video.
As was already mentioned, too bad there wasn't Ultra high speed images like there was with Ivy Mike. But, that Shot's Video, doesn't have much of the Fireball.
i slowed down the audio (in Cubase) at the part where they sound like chip monks 3:20 the voice says:
"This picture was taken from an aircraft flying at 12,000 feet.... 60 miles out from zero"
A pretty good method of distance from the explosion is to count the time after the flash start and the shockwave hits you .Sound at sea level is about 5 seconds a mile . So if the shockwave gets to you in 20 seconds it’s 4 miles away
Just slow the playback speed down numbnuts
You're Right I don’t recall the option being available 4 years ago, when the comment was posted.
mrajczyk Thank you...as I immediately started to do the same.
Chip monks? Is that the Keebler elf in a monastary?
2:55 to 2:56 You can see it detonate from really close. Yes that tiny glimpse of bright light (Even tho this is high speed film) is all you would see before you would be turned into plasma..
No i can't see it.
Αλεξανδρος Πατσαλος well thats how quick the camera got vaporised
*Before you was turned into the 4th state of matter*
Scary

THANK YOU SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCH for posting this. This is ultra-rare footage and despite the fact that there is no sound, this is some of the best footage released yet.
There is sound. At 3:18 there seems to commentary of the explosion by Donald Duck himself.
@@700007123 4:38 too
It would be fascinating to see a microsecond to microsecond frame by frame "video" of the explosion to watch as the unearthly plasma of x and gamma rays and infra red heat overcome all matter in a 2 mile radius. Those very expensive, solid concrete/steel towers with the very large mirrors probably became part of the plasma within several milliseconds and completing their job in that time. Absolutely amazing. I would guess that the temperature at the core of the shrimp device was on the order of 150 million degrees farenheit.
There was a shack off to one side of the fireball that detonated with around a 5kt yield. A light pipe that was in vacuum carried the radiation from the fireball to instruments in the shack, which due to the unintended high yield, vaporized the instruments and shack.
I love the guy at 4:30 lol Mr. Enthusiasm.
Actually I kind of enjoy the "stale" delivery, it lets me concentrate on the topic rather than the speaker or his delivery. Listen to it again, and see if there is even one word you did not catch. Now imagine it in today's dialects, with the typical speaker so pleased you get to hear the sound of his voice that he turns it into a sing-song of vocal gymnastics that makes listening a chore. It's almost as it we today identify perfectly spoken languages as "old school", as if there is something too conformist about being accurate and succinct.
There are reasons for that. It's military communication, and there are rules. In those days when it really counted (like a nuke shot) you followed the rules or someone fried your career forever. There literally were rules of speech for radio communication. Still are I'm sure.
"Exercise! Exercise! Exercise! Standby for an exercise message from the command post!" From my day if we heard that on Friday morning it was going to be a long weekend. They said "Exercise" so the listening Russians would know it was just an exercise. lol
well, if you had to talk about your experiment exposing hundreds of people to radiation, i bet you'd not be happy about it. besides, this is a military video, if he were giving this report like a weather man, his career would be over
😂😂😂 mr energy!
He probs told em it wasn’t a good idea to do it for potential radiation spread through wind currents, but they told him “bob we dont pay you to tell us what not to do”, his whole demeanour screams “fuck this shit”
Scientists: Hey Castle Bravo device, I bet you won't exceed 5 MT yield.
Castle Bravo Device : Hold my beer....
Hold my lithium
Hold my plutoniun
Hold my uranium
Hold my antimatter
Hold my tritium
The fact the fallout extended 280 miles from the blast zone is insane.
Hummanity is fucked if a major nuclear war breaks out.
Well, they didn't expect half of the lithium in the warhead to contribute to the blast, but it more than doubled the warhead yield.
It pretty much was a case of whatever could go wrong did on that test.
Love the B&W contrast! You see the Bells, Ice Caps, Wilson Clouds so clearly, esp. as it rises and several caps "fall" in synch! Beautiful post! Thank you!
there is a colored version of this with higher quality and less noise. I think it's digitally restored
Do you have the link?
@@tfishappeningxd5915 I think it's from this channel also
Where? Please Link
Easy go to north korea and declare war on US to see the full blast with real time audio. And its HD
Fake like the moon landing
Wow. New castle bravo footage. Thanks for sharing.
BTW: the techs who worked on the Shrimp (the name given the device), all signed the side before it was detonated. lol And the fission primary end of the device is the end with the cone on it. It's part of the neutron reflector.
The most important takeaway about the castle bravo test was probably the fact it put the worry about nuclear fallout into the mind of the general public increasing a general awareness of the potential and likely hazard of a byproduct of nuclear war. increasing public pressure to not use nuclear arms
Which was and remains a good thing.
I used to work on the things and frankly, I call them products of the insanity factory.
The only realistic usage for them is, maybe, just maybe, asteroid diversion by near-miss detonation to ablate part of one side of an incoming asteroid that's way far out.
3:18 caught me off guard, who let the Minions into the recording booth
😂
the bomb was so powerful, it gave this black-and-white film the illusion of color
3:17 "This picture was taken from an aircraft flying at 12.000 feet, 60 miles off of zero"
They said Mike would have obliterated all 5 New York boroughs. That was 10.5. Bravo was 15. Hard to even comprehend.
roquefortfiles and tsar bomba
I love the no smoking signs at 0:53 👏
Absolutely chilling. They all knew something went very wrong. I love it
you're an npc
No mention of the dose the firing party at Enyu took (at twenty miles) before they were rescued.
I was actually was on a boat during that shot. Damn I feel old
Wh at
No way?! You saw the explosion in person??
that man reading the fallout doses is clearly reading a script which he doesn't agree with
Agreed. I think they got exposed heavily. His body language says he is lying and very upset inside about it. He is a doctor and I'm sure this video was being sent to the brass at the Pentagon and White house.
Yes, cause it's mostly PR Fluff and stinking lies
Put the speed at 0,25. Go to 2:55. Advance slowly frame by frame by clicking repeatedly very fast play and pause (the same button).
At 2:56 u will see in one frame the device going off before the camera is vaporized.
This video needs to be properly deinterlaced. It is originally progressive, but has been telecined and was not properly de-telecined. That's why it has artifacts.
Send an email to Peter Kuran.
Hahaha!! I love Dr Dunning's enthusiasm on the matter.
Nicholas Boyd Yeah, "Nick", ol' Doc Dunning seems like he would have been an interesting bloke to know--a REAL life of the party!! And, I imagine that he WAS; they just had to have had some interesting parties, from time to time, to blow off the steam from their intensely assiduous and serious work. Ya just gotta love him, right??
And Dr. Teller, pray tell, could play a mean Chopin, on the piano, if there were pianos in the wardrooms of the nicer Navy ships.
And, hard to realize, but a lot of the baby-faced sailors, Marines, soldiers, fliers, and technicians there, would all be in their mid-Eighties, if not already dead.
+Swithin Barclay comm a bit dated but... yeah ol do-or-die Dunning looks like a real scream at hash (Oppenheimer, that Buddhist thing..) parties, notice the frantic way these technicians were working?? the waves are normal speed, so...NONE OF THESE FUCKS REALLY KNEW, ABOUT ALL THAT SHIT, THE NATIVE POPULATION, THE JAPANESE FISHING BOAT, THE YIELD...but that flash, man, and that HEAT, even on a nice tropical night that HEAT...bet the fuckers got a good bone-on from THAT...ya gotta know, at LEAST 50%of the release energy went into fallout, the fireball dissipated so fast compared to other hydro shots...

Because he is aware of the damage caused to the environment
The scientists that worked on calculation warned of possible "run-away" yield of Bravo, potentially far exceeding the 6MT yield, but Alvin Graves had probable attitude: so what if, we will do it anyways...
So they knew Bravo could be far bigger than "expected" yield with "acceptable" fallout.
If there weren't for the ironically named "Lucky Dragon 5" ship crew, we would have never known about Bravo and dangers of fallout since the Operation Castle was super secretive (because it was the first testing the weaponized versions of H bomb, previous was Ivy Mike, that was more like a small factory than a deliverable bomb/weapon) and everything would be hushed up.
What did the towers around the shot cab do? Were they some way of photographing the early fireball? If so, how did they work? They would have been destroyed within microseconds of the blast. It amazes me how they were able to collect data from these shots with not a single computer (as we know them) around.
They held mirrors that imaged the case of the device yo cameras several miles away in a blockhouse, which used streak photography.
Makes you wonder why they removed most of the audio, I wonder what they could have said that makes it still classified today
Yep
"And on that day. I was reborn." - Godzilla
"Castle Bravo's yield was *2.5 times more than predicted* , which led to the *unexpected radioactive contamination* of areas to the east of Bikini Atoll." Wikipedia
My grandpa was in this test. I've been hearing stories for almost 40yrs. now lol
Keith Zariski, do you know what your grandpa's reaction to the test was?
Well they did use the wrong type of lithium in the blast
Gary Eppenbaugh not so much; there were two lithium isotopes in the lithium deuterium filler. it was thought that only the lithium-6 would react but as it goes, the lithium-7 got involved as well and boosted the yield big time. Quite a miscalculation 😬
@@keithzariski2026 was youre grandpa with the lucky dragon?
The removed words were likely, in the famous words of Super Dave Osborne: "HOLY $~*#!"
I've never seen this before. Many thanks for posting it!
By the way, there is sound in the last 5-10 minutes.
Thanks, David
I have always wondered how much wild life was wiped out?
Me too. Plus what about the mutant fish and birds that could be created .
Below is my best analysis and explanation of the light intensity fluctuations picked up by the camera
2:58 @0.25x speed:
The fireball dims extremely quickly after detonation, the expansion of the fireball and probably moreso the emission of energy in the form of light reduces the temperature extremely quickly, and that's why it's only a flash of that brightness level. I think that the light increasing after that is the fireball moving out from below the clouds around it, almost like a sunrise, and it is still decreasing in temperature.
What do you guys think?
BBQ'd islanders.
I wonder if the world will ever get comfortable enough with the presence of these things to allow us to see the high speed footage of these shots the microsecond after detonation? Right now, I'm assuming, it would give too much away about timing and configuration with the primary and secondary.
why? its a waste of time
I'm glad someone told us why those concrete pillars were built right by the shot cab. Also, seems like they could declassify all of the other film of this shot that "they" must have. Certainly the technology of Bravo has to be laughable by today's standards.
Anyone can look up how to build one but there are still secrets. Plus even if nuclear technology worked the way you're suggesting it does, that would mean allowing bad actors to have low yield bombs. Not a good idea!
It's the same technology in modern bombs, just miniaturised and much lower yield.
Oh, yes, we evacuated the native population 51 hours after the test. Jesus H Corbett...
Great film, thanks for posting, can see why it was classified.
Read the history. The bomb was much, much bigger than they calculated. There was never supposed to be so much radiation and fallout. The people would have been evacuated before the test. We're not Soviets...

That was not really a test. They were attempting to destroy a Muto named *GORJIRA!*

@@celtic867 Arrrrrrgh, my spell fail. Thanks Celtic.

Ok, the voice at 3:18 is going to give someone a heart attack.
Time to add more Operation Castle video's... like this.... many more exist, but remain classified...
The sound was so brutal its still classified.
Wonderful to See Video of a closer look at all the Machinery and Sensors Hooked up to Shot Shed.
Pro tip: Play at 0.75 speed for it to look somewhat normal
It's a shame they don't restore the camera original negative, or at least scan the print they have for restoration...
Rare footage of megumins daily explosion practice
-1954
2:20 what were all the pipes for
I found out, it was to measure the light rays coming from the explosion. The pipes lead to detectors down range which measured the light.
3:20 gremlin 👹under your bed 🛏
0:37 I see the only things left on the island where The timing trailer and two small trucks all vaporized
you can tell that the guys giving the presentation did NOT want to be giving it lol
When something has a "No Smoking" sign on it in 1954, you best believe they mean NO SMOKING.
I'd like to thank all of the brave soldiers and sailors who were knowingly volunteered to be test subjects in these nuclear detonations by the United States government!
Secondary thanks go out to the islanders who gave up their homes and health for the progress of science and the United States volunteer citizenry who agreed to live down-wind of the test sites!
Honorable mention goes out to the Men of Science, who knowingly subjected unknowing fellow countrymen to the ravages of radiation! If I had my way, and you had better hope I never do, your reward would be a bullet to the brain-pan!
i was so tempted to destroy my comp coz i just couldnt stand having no sound
You mean "I was tempted to destroy my computer because I dont like watching videos that dont have sound." And why would you be mad it sounds like a goddamn nuclear explosion.
A lot of these videos of nukes don't have the actual noise a nuke does BCS it was loud and tape was magnetic so kinda fragile trying to get sound back then, but there is one video with the sound of a nuke which is not that we all think as a constant noise is just a great Boom!

So if this was only 60 miles why did people in cypress hear the shockwave from the explosion in Beirut which is 125 miles away but this plane flys by no problem at only 60 miles away this explosion surely should have done damage to this plan of even rocked the camera or am I missing something? Sorry not a doubter just asking why this seems wrong
I need to figure out how to convert Roentgens to Sieverts. Nobody talks about Roentgens anymore.

Teller monitored a seismograph for the Mike shot in 1952.
And reported its success by stating "it's a boy."
2:20 just think of all of the stuff pipes buildings items left behind all vaporized into dust The island experienced The energy of 10,000 Suns
I missed the mention of "Lucky Dragon No. 5" here.🤓
4:25 Gordon Donnie ladies and gentleman. He is oozing with enthusiasm about the presentation that hundreds of Marshall folks will die slowly from radiation poisoning.
If it can be done it will be done, this is science, anything goes, their is no morality in science.
turned a tropical paradise into a nuclear waste land... good job, uncle sam
koko1914 Now Godzilla has a home.
OpenGL4ever Castle Bravo is - partially - the genesis of Godzilla. Castle Bravo was on March 1, 1954. Godzilla was released in November the same year. The miscalculation of Bravo's yield, and the following accident where Japanese fishermen were subjected to the fallout - with one of them dying - along with Hiroshima and Nagasaki fresh in mind no doubt drove the creation of the movie.
+koko1914 For less than 6 months, plants were growing back in less than a year. The "island" where the shot occurred was manmade on a partially submerged atoll. Within 10 years, there was no evidence in the native biome's flora or fauna that it ever happened.

koko1914 thanks for not appreciating the fact that we still have a country that's not under communist rule. by the way Bikini and the surrounding islands were shit and still are shit. but the seafood is good and not poisonous because the radiation in the water has disappeared.
How maddening, to have that device, and a whole world full of assholes, and not be able to use it.
Don't you think it was NEGLIGENCE and not MISCALCULATION. It was documented that The Chief Scientist of the Programme said that " Castle Bravo Could Be Big". The US Scientists of AEC( Atomic Energy Comission) and the DOD knew that the TRITIUM can lead to devastation & destruction. They knew that it could be some where close to 15 Mt. They took the risk. That's the typical "We will see, what happens" attitude. They even knew they might have to give million dollars in compensations. Thanks👍
What? Tritium was not the reason for the "miscalculation". It was Lithium. LOL
This comment came from your ass
They actually knew it it would go big, but no, Dr. Graves (the guy that appears before the depression-ridden presentation guy at 4:26) and people similar to him probably dismissed the entire worst case scenario, which would happen anyway.
He was exact embodiment of a person "We will see what happens". He was next to Slotin when Demoncore-incident occurred, he survived thanks to Slotin in front of him received full dose of neutron radiation. And the critically experiment was performed with screwdrivers, brilliant.
And after he recovered from radiation sickness he continued working afterwards on nuclear weapons, and smoked heavily as if radiation risk is not existing or harmful.
He lived to age 55, others claim that it's his heart failure is main cause, because of thr genetics, but that's just bs. If he didn't received the dose he would probably lived till his 80s easily.
Edward Teller was the smartest, he just designed the concept and didn't go nowhere near test sites and lived to 90+age.

They thought it was going to be much smaller.

CASTLE BRAVO my favorite!♥️
Does anybody know what all those pipes were for? It looked like a massive waterworks instalation but what for?
They were viewing ports into the core of the bomb. The pictures were sent optically to remote cameras. They obviously functioned for about a millisecond.
The pipes carried light to the streak cameras, not pictures. The x rays from the primary would heat the secondary in nanoseconds, not milliseconds. One can assume that the light profile at each of the diagnostic pipes would give information as to the progress of the explosion. I believe that the blockhouse many miles away where the cameras were situated was destroyed in the fireball.
The Mike test had a special plywood tunnel filled with helium balloons to carry neutrons to the diagnostic equipment.
"who was spongebob? In google maps bombs crater found spongebob Squarepants real life"
I'm not sure o'l Gordon didn't get zapped with some radiation....seems tired and out of breath just talking.
It's hard to imagine the destruction of an explosion a thousand more powerful than that of the bomb that was dropped on Hiroshima. This is assuming that a thousandfold yield increase renders it a thousand times more potent.
Hiroshima is weak
3:18 that scared the shit out of me
me too, but do you have any idea what that can be from?
after hearing it many time it sound like somebody was saying some coordinations, maybe that was from anplane

It was amusing to see all this then state of the art technology being worked on by all those beach bums. With Dr. Charisma at the end. I notice he didn't mention the Lucky Dragon, and downplayed the native peoples exposure.. Thanks for sharing.
+pschroeter1 Dr. Graves and others came under some criticism later for allowing themselves to become obsessed with the rescue of a test group in a bunker on Enyu Island (about twenty miles from the device), and neglecting to address the evacuation of others on more distant islands.
psychroeter: The film isn't dated, but seems to be quite soon after the test. The Lucky Dragon may not have returned to its home port yet. As far as downplaying the natives exposure, what would you like for him to do? No one died, and over 50 years of medical followups have found minimal resulting effects.
