Operation Castle (1954)

Kudos to staff for creating the digital version of an important piece of scientific and military history.

@@kevinsmith9502The B41 was a so-called "special capabilities weapon." At the time it was produced, no one was sure what nuclear war with the USSR was going to look like exactly. Because of this, it was logical to think of every contingency. Remember, the original U.S. nuclear battle plan called for the complete annihilation of Russia, the Warsaw Pact nations, AND China. We would soon be looking at nuclear battle plans that anticipated 1.5gigatons of explosive yield in the first 24hrs. By the early eighties, the total explosive yield unleashed by WWIII would have been five to six gigatons. I encourage you to watch the KZbin video below.

One of the scientists observing this said the heat from the bomb was incredible. And it kept getting hotter as the time went on. Not cooler like you might expect. And they were 50 miles away and the heat was nearly unbearable... at 50 miles!!. Half your distance again to this 25 miles. You'd be cooked to death let alone pulverized by the shock wave. If you were in a city with this you'd be boiled and turned to burnt carbon in seconds before anything else. How lovely!!

[@Crimsonedge1]

Tsar Bomba (57MT) would have given 2nd degree burns at 100 miles had anyone been close enough when they set it off and it actually smashed windows in Helsinki 600 miles away. Also, sounds crazy but a city would be a good place to be. Plenty of surrounding buildings to shield you from the initial pulse. Sure, if a nearby building collapses then your screwed but out in the open, you have no chance. So long as you're not at ground zero in which case you're dead no matter what, its the initial gamma pulse you need worry about protecting yourself from. After that, it's fallout. That's easy to deal with. Just walk towards the wind and don't stop walking until you're miles and miles away. Plus, most modern weapons don't actually leave much fallout due to the way in which they're fired. A ground burst would pick up the most debris and create the most fallout but actually deals the least damage as intervening terrain and buildings slow the blast wave. Weapons are mainly deployed at about a couple of thousand feet up so the expanding wave slams into the ground and the reflective secondary wave catches up with the primary creating a localised area of extreme high over pressure and devastation. Due to being detonated in the air though, very little debris is picked up and carried vast distances in the mushroom cloud meaning little fallout.

I was used to doing this because I had previously taken pictures on highspeed film of test firings, this time no camera. When the launch came I watched it go nearly straight up, this was unusual. because the Terrier missiles were usually launched at a greater angle. That missile was an AA weapon that in a pinch, they said could strike a ground target. I had seen several detonated, mostly self destructed because they flew outside the radar guidance envelope. This detonation was much different, there was a brilliant fireball overhead that lasted several seconds like a second sun, then it disappeared with no sound.

[@bboucharde]

Maxx Madd Maxx, Thank you for your service in the Navy. I was in SAC ("Peace Is Our Profession.") However, your comments about the Trident D-5 (carried on all US Ohio-class subs) are totally wrong, and YOU should know better. The Trident D-5 MIRV bus is normally set up for eight 300-to-475 kT thermonuclear warheads. Some sources indicate that the bus is technically capable of carrying 12, and others claim 14, for special short-range missions. But as far as we know (published sources), Trident D-5 currently carries eight warheads per missile. Your estimate of "3 to 5 Megatons" per warhead is way off, and not supported by any published source. And, if you are familiar with the much improved CEP of these systems in the past 20 years, you would understand that multi-megaton warheads are not needed nor cost-effective, for the Ohio-class/Trident mission of deterrence. Here are a few sources that back up my points: Trident II (D-5) fas.org/nuke/guide/uk/slbm/d-5.htm www.lockheedmartin.com/us/products/trident-ii-d5-fleet-ballistic-missile--fbm-.html www.globalsecurity.org/wmd/systems/d-5-specs.htm www.astronautix.com/lvs/trientd5.htm You are welcome to your opinions, but facts are facts---as far as published sources available to the general public go.

[@michaelgrey7854]

Nuclear bombs are ao fascinating!

[@rtqii]

I have read many witness descriptions of the Castle Bravo shot after effects. Someone calculated, after measuring the crater, how much material had been vaporized/removed: 10,000,000 tons of coral, rock, and sand. The coral was vaporized/pulverized and mixed with fission fragments. Bravo was a dirty bomb, most of the yield resulted from fast fission of the enriched (37.5% U235) uranium tamper. The fusion fuel was significantly more potent than predicted, more fast neutrons were produced and more fast fission of the tamper resulted. The tamper weighed over a ton, and it produced over a ton of highly radioactive daughter fission products. The fallout came down like a snowfall of radioactive coral ash, and it was prompt lethal in the area 60 miles downwind from the detonation site covering an area of about 2000 square miles. Anywhere in that area you got a lethal dose of radiation in just an hour or two.

U238 is what undergoes fast fission and is desirable because depleted uranium (u238) was a waste product from generating nuclear fuel (refining u235)

probably bigger

[@puncheex2]

BigBoss1982 No. Google "current nuclear weapons" to see what is in use. The current weapons were generally all built in the 1980s. Plutonium has not been newly manufactured in the last 20 years. The largest current weapon in the US arsenal is 1.6 MT.

[@puncheex2]

***** No, I don't think so. For one, they have been judged useful only for deterrence; keeping them quietly on a shelf after having been effectively banned is not deterrent effect. Militarily they are pretty much useless; the ones on the missile silos and submarine IRBMs mean a lot more in terms of military effect, even strategic effect.

[@puncheex2]

They have been disassembled. The cores are still available, unless, like many from the USSR, they have been degraded into nuclear power fuel. That's about the only way to "destroy" a core. The parts beyond the core were scrapped, except the explosives which were probably burned. Making a CT out of this is silly.

[@aardvark9100]

@bjzq8 The entire nuclear reaction takes place in roughly a millionth of a second so the bomb vaporization would be so quick that there would be no visual of anything just like you said. The Trinity test had very high speed photography where you can see the fireball slowly devour the tower. Operation greenhouse had one with multi million fps reference: watch?v=kfbHwj71k48&feature=related at 6:55. The Kraus/Ogle box and vacuum tubes were the only real way of "seeing" the initial explosions.

Anti-matter annihilation provides 43MT of energy per kilogram of input matter. There is about 12 kg of plutonium in a bomb, which makes the total about 520 MT, about the total energy released by all nuclear bombs ever exploded. But the Chicxulub meteor which killed the dinosaurs released 100,000,000 MT, and didn't quite make it to break open the crust and expose the Earth's mantle. So, no, it would take considerably (!) more then a bomb core to do the job,

Look up Declassified U.S. Nuclear Test Film #54 on KZbin. Tests were also done with dummy nuclear bombs in Plumbob to extract information that were successful. Type in Declassified U.S. Nuclear Test film #21 on KZbin and go to the 11 min mark to hear of these tests.

[@roquefortfiles]

I was reading that if the Tsar bomb was detonated and you were in the open 100 miles from it you would still be too close. It would produce 3rd degree burns even at that distance. I can't even imagine what it would be like being 20 miles from this thing. Sitting in your car and it goes off. In about 2 10ths of a second you would be boiled out of your skin before you would even have to worry about the blast wave. Probably be a nice cooling effect to the 10 million degree fireball.

[@daveeyes]

You have to remember these were tests to learn what worked and what didn't. The US had exploded 1 hydrogen bomb in the Ivy test, and that was 10 Megatons. There were unexpected and unknown reactions that happened during Castle. Castle Bravo (test #1) went well over its design, to 15 Megatons. It pretty well trashed the test area and even gave the firing party a pretty rough ride. Now reflect that a 20 Mt weapon was, for some time, a oft-used design in the USSR's weapons.

[@kollusion1]

When you think about the amount of destruction caused by the 15kt, & 21kt weapons dropped on Japan, you've got to wonder what these guys were trying to achieve, with weapons 1k times the destructive power of lil boy, or 5 times the destructive power of all the weapons used in WWII?

The Hutchison Effect, if anything, is a electromagnetic force phenomenon. It might be used to counteract gravity, but it doesn't affect it, shield it, or otherwise change gravity. But there is nothing unusual about that; airplanes counter gravity without affecting it.

I would lean towards false. Superpower governments are accomplished liars. They employ top tier psychologists and sociologists to propagate their messages.

[@ApolloWasReal]

In its one test, Tsar Bomba yielded 50MT, 97% from fusion. It could easily have produced 100MT had its tertiary stage used U-238 instead of lead. Once the Teller-Ulam principle was demonstrated, there was no technical challenge to either the US or USSR making arbitrarily huge bombs. They just had no practical use -- not that any nuclear weapon is terribly practical or useful except for deterrence.

[@Tsumami__]

ApolloWasReal Nuclear weapons are absolutely practical, and have proved that in the past. Not necessarily ridiculous hydrogen bombs, though.

[@Evan_Bell]

Goddess Usako why are "hydrogen bombs" impractical?

[@anhedonianepiphany5588]

+Evan Bell: Methinks Goddess Usako doesn't realise that virtually all nuclear warheads in both large arsenals are two-stage fission-fusion devices, a.k.a. "hydrogen bombs"! Me also thinks that she doesn't get that over a certain yield threshold they are absolutely _impractical,_ as the energy is lost to space. ApolloWasReal was specifically referring to huge thermonuclear devices (hydrogen bombs) with yields in excess of the Tsar Bomba, which places them outside the scope of practical weapons. I have no idea how someone could twist the meaning of his comment into "nuclear weapons don't work"! +84 LoneDreamer84: Your scenario is only valid for an imbalanced system where there is an unopposed nuclear-capable state.

[@allangibson8494]

@@Evan_Bell The full yield Tsar Bomba would have the delivery aircraft in the blast cloud. The Tsar Bomba is too heavy to be delivered by rockets of the time. The ultimate yield limit is 250Mt at which point the fireball exits the atmosphere and vents into space meaning doubling or tripling the yield produces a bigger flash but the same size bang.

I wonder what effect the bomb would have on a modern city with far larger structures like 40 story office buildings. Then again i read that the blast over pressures near GZ are like a 30 million pounds per square inch. Hard to fathom something that could make a modern city... DISAPPEAR!!

Okay, so I'm late by like 7 years. so I'm assuming you've already Learned​ the answer to this. but, if you're still wondering. look up a really nice tsar bomb video. Like a long one. with blueprints and the like. they added tons of pretty Modern urban structures. at least at the time they performed the test. They built like a whole town on that island. strong buildings, steel structures and the like. So this truly was. the best test. I learned tons about how high yield weapons may alter. something more modern. You should look into it. really interesting.

The typical energy of a supernova is 1-2e44 joules (5e28 MT) of energy. Our sun is an intermediate sized star; it is too small to undergo a supernova termination.
