ok... here is the deal.... the Tsar Bomba was ^#%$ing huge.
No seriously... MUCH MUCH bigger then you think.
it was 10 times the combined power of all the conventional explosives used in World War II
it was 10% of the combined yield of all nuclear tests to date.
and mostly....
It was the equivalent of over 1kg of antimatter going up.
1 ^#%$ing kg.... of ^#%$ing antimatter.
It broke windows in Norway and Finland and its shock wave was VISIBLE in the air 700 km away.
It is impossible to get people to understand how much of a monster it was. AND.... and this was it dialed down to 1/2 its maximum yield.
No one has been crazy enough to test another nuke of its size. Even in the height of the cold war no one was crazy enough to test something like that again.
If you want to see the effects of various nukes there is a simulator here: http://nuclearsecrecy.com/nukemap/ (I have no idea if it will get you on some sort of list if you access it).
The takeaway is that, as long as it is just a single nuke, the damages are rather underwelming, except for the Tsar bomba.
One missing piece to the puzzle from that page is accuracy and hardened targets.
These days you can just about crush an individual ant with a missile fired from the other side of the planet, but it wasn't always like that. Accuracy used to be much worse, especially on the Soviet side. At the time the Tsar Bomba was developed, you might be lucky to get your bomb within a mile or two of your target. Even bombers were frequently way off target.
Then consider that a lot of the targets are hardened military targets, not cities. Destroying cities was always either incidental (they contained or were near military/political targets) or a last resort (convince the enemy not to attack by threatening his population in retaliation). Primary targets were (still are!) things like airbases, missile silos, and command centers. Many of these are hardened targets. A more normal-sized nuke going off a mile or two away from the intended ground zero will still wreck a city, but a missile silo can take it. If you want to be sure of getting targets like that, you either need to be a lot more accurate or you need much more powerful bombs. Accuracy wasn't possible at the time, thus huge bombs.
If you look at the evolution of nuclear arsenals, it was a race to bigger and bigger bombs until sometime in the 60s, at which point accuracy started improving greatly and the bombs got smaller again. For example, the US fielded lots of 9 megaton bombs in the 60s, but now the typical weapon in the US arsenal is under one megaton.
> I have no idea if it will get you on some sort of list if you access it
I guess it will get you on a list of nuclear history enthusiasts. Apart from that, this sort of thinking is really just mild paranoia. While I recognise that the NSA monitoring is a big deal, I don't think that it can be extended to mean that ordinary people accessing sites like this will become targets.
So, don't worry, and go ahead and access the site, and also read the guy's blog - it's very interesting.
Not sure I would agree with that - a single 800kt detonation over Manhattan looks pretty bad to me and a realistic attack would probably have had many tens of warheads used.
Here is a rather jolly 1980's BBC documentary that spends a lot of time looking at the effects of a single 1Mt warhead on London:
Well when I mean pretty underwhelming I mean that I kinda expected a nuke to take out the entirety of New York + a big chunk of the east coast. I mean these are the weapons of doom, right? The weapons that will end the world?
And yet if you are just 30 miles from the target the first time you are going to notice is when you turn on the TV.
Keep in mind that at the height of the Cold War, both the US and USSR had thousands of nuclear warheads. A single nuke might not be a civilization-destroying weapon, but a carpet bombing of nukes sure is.
Well, with a single 25Mt ground burst in New York and the wind in the right direction Boston would be getting 1000 rads/hour - which is not going to be good if you are not in some kind of protected area.
Mind you, although the Soviets did have 25Mt warheads on ICBMs they were targeted on key bunkers - Cheyenne Mountain, Raven Rock Mountain etc.
Those rings show the area of near total destruction and death.
The area of severe damage and less instant fatality is maybe twice as wide.
Outside of that there's another ring of significant damage, but the probability of survival increases (as long as you're not near a window when the shockwave hits.)
The map also doesn't show fall out or the effects of a possible firestorms.
It's an option you can select - you can also set wind speed and direction (drag the windsock icon about). You also need to make sure it is a ground burst as an air burst won't produce much fallout.
No survivors. Within tens of minutes, everything within approximately five to seven miles of Midtown Manhattan would be engulfed by a gigantic firestorm
Furthermore:
The fire would extinguish all life and destroy almost everything else. Tens of miles downwind of the area of immediate destruction, radioactive fallout would begin to arrive within a few hours of the detonation.
Manhattan has a daytime population of more than two million people.
When nukes stop being about the M.A.D. concept and more about being a propaganda tool... It was designed to shock. And it surely did. Soon after the detonation, Andrei Sakharov himself (behind the Soviet "Third Idea" nuclear weapon design) began speaking out against nuclear weapons and became a Soviet dissident.
The trouble with the 100% yield version that was originally planned is it would have dumped a lot of radioactive fallout on Russia. The 50% version was not so much dialled back as a different design with some of the uranium components replaced with lead.
Thank goodness. I'm also glad they tested it high enough up to prevent the fireball from touching the ground. With a modern bomb you get fallout from the primary stage but the vast majority from an air burst is going to be from the outer uranium-238 shell which absorbs all the extra neutrons from the fusion and splits without emitting any neutrons itself. This isn't a problem with lead for reasons I don't understand and with the air near the bomb you're just doing stuff like turning nitrogen into carbon-14. The results either decay immediately or last for a thousand years and so aren't particularly radioactive. If a bomb goes off near the ground or sea water then there's plenty of stuff possible products with those nasty intermediate half-lives.
Well, lead is a very stable element from what I understand. Radioactive elements like Uranium are radioactive because they're inherently unstable, such that fission is 'easily' doable and releases a lot of surplus energy.
Looking it up in a reference, natural lead is about 1% Pb-204, 24% Pb-206, 22% Pb-207, and 53% Pb-208. These are all of the stable isotopes.
If Pb-204 absorbs a neutron it turns into Pb-205, which isn't stable but its half life is ten million years so it's only very weakly radioactive. The -206 and -207 turn into other stable isotopes, of course. So those don't matter so much: about half of your neutrons enter lead nuclei which can safely absorb a neutron.
The other half, the Pb-208, turns into Pb-209. Pb-209 is radioactive with a surprisingly short half-life of 3.25 hours, so that's gone in a matter of weeks.
The nasty stuff is the lead atoms which happen to absorb two different neutrons during the explosion. This becomes Pb-210, which has a half life of 22 years: short enough that it's going to be emitting a bunch of radiation, long enough that it won't be gone after a few weeks.
So the answer is probably "it's very rare in these sorts of explosions to have two neutrons hitting a single lead nucleus." There are other possibilities (maybe they got the lead from spent nuclear fuel or centrifuges or something and it's all Pb-206) but that sounds like it's the most plausible.
It would also have been far more terrible even in the 50% yield if it had been let to touch the ground for the energy to turn into seismic waves. The energy corresponded to a 8.1 on the Richter scale.
A 1-Megaton explosion has the same energy as 46.55 grams of matter. 50-Megatons is thus about 2.32 kilograms, or 1.16 kg each of matter and anti-matter.
A kilton of TNT is said [0] to be equivalent to a cube 27.8 feet on a side. 50-Megatons would be a cube over 1000 feet on a side.
>No one has been crazy enough to test another nuke of its size. Even in the height of the cold war no one was crazy enough to test something like that again.
and thanks to the test we know for sure that ignition of the atmosphere with even such a bomb still wouldn't happen :)
Whenever the Tsar Bomba comes up, the potential for it to have ignited the atmosphere is always brought up. What exactly, however, does that mean? (Apologies if that sounds sarcastic; it's a genuine question!)
My guess is that the heat/EM could induce a state change in atmospheric gasses into plasma. Would this be a chain reaction that ultimately encircles the world? Also, what are the implications of that (locally or globally)?...
It might get brought up because before the first atomic bomb was detonated, one of the physicists who worked on it (Edward Teller) suggested the possibility that detonating the bomb would ignite Earth's atmosphere. There's a bit more information here: http://www.sciencemusings.com/2005/10/what-didnt-happen.html
There is an old Soviet sci-fi book from 50s by Alexandr Kazantsev, "The Burning Island", where he depicted an island in the Pacific Ocean producing some catalyst that made self-sustaining exothermal reaction between nitrogen and oxygen possible; the reaction had sucked out all oxygen from Earth atmosphere. The book has several scientific discussions, but the essence of the catalyst is avoided.
There is another sci-fi book by the same author, "Faetians", where he depicts the fifth planet of the Solar System, Faeton (a hypothetical planet between Mars and Jupiter that could be the source of the asteroid belt), destroyed by nuclear fusion of its ocean hydrogen after several powerful nuclear explosions. The author gives even less explanations there.
So, I think the atmosphere explosion is a myth rooted in sci-fi books, at least in Soviet culture (I have not yet encountered such plots in American literature/movies of that time, but maybe I'm just not familiar enough with it).
This is only a problem if it's possible for the transformation to be self-sustaining. That is, the act of transforming atmosphere causes yet more atmosphere to transform. Only in that situation would the whole planet's atmosphere burn.
Let's make an analogy with trees. You can't burn a living tree outright. Or so you'd think. But once there is enough energy around a forest fire can jump from crown to crown faster than you'd imagine possible outrunning the ground fire. This will continue until the fire runs out of fuel or the conditions change enough to put it out.
There is so much energy in the system that the burning crown of one tree dries out the matter in the crown of the next to the point where it can be combusted in an extremely short time, contrary to ordinary conditions when lighting 'wet wood' appears not to work.
The whole point was that Teller thought that the reaction might be self sustaining once the activation energy was reached.
Think about it: someone made the call to ignore that possibility and pull the trigger on deployment even if they weren't sure about the outcome. Possibly the single most irresponsible deed in the history of man.
I said to myself, "What have you done, Hamming, you are involved in risking all of life that is known in the Universe, and you do not know much of an essential part? [uncertain variable]" I was pacing up and down the corridor when a friend asked me what was bothering me. I told him. His reply was, "Never mind, Hamming, no one will ever blame you."
Share of hydrogen in the atmosphere is almost negligible; nuclear fusion of ocean water is a bit more likely, although it still has to meet too many conditions.
My understanding was you can actually get a chain reaction in the world’s oceans, but it would take significantly more energy to kickstart than any atomic bomb designed.
PS: Fusion is one of the few equations where you will see X^4th power so you vary quickly go from it's fine to big boom. However, igniting the world’s oceans would take enough energy to kick off that we would be dead either way.
The Tsar Bomba was an experimental weapon, but the United States had the B41, a three-stage thermonuclear weapon with a yield of 25 megatons. Four of these would have been as powerful as the Tsar Bomba; the U.S. manufactured 500 of them. http://en.wikipedia.org/wiki/B41_nuclear_bomb
In the 1960s the U.S. Strategic Air Command ran a continuous airborne nuclear-armed patrol (Operation Chrome Dome), so there was probably a 25 megaton weapon in the air for much of that time. http://en.wikipedia.org/wiki/Operation_Chrome_Dome
It's also worth remembering that the limiting factor on the yield of the Tsar Bomba was the carrying capability of the Tu-95. The Teller–Ulam design for thermonuclear weapons is scalable: you can keep adding stages as long as you have the uranium, plutonium and lithium to make them with. Edward Teller supposedly designed (or at least contemplated) a 10 gigaton bomb: http://blog.nuclearsecrecy.com/2012/09/12/in-search-of-a-big...
> Edward Teller supposedly designed (or at least contemplated) a 10 gigaton bomb
That guy was batshit crazy, pardon my French. I know that the Dr. Strangelove character was pretty much based on him, I know about and I partially understand the reasons behind the nuclear arms race, but when you read about plans like this you just start contemplating about the end of humans as a species.
How is he crazy? When nukes are on the table either you implement a MAD-like policy or you die in nuclear fire. There's no real middle ground with weapons this powerful. Its rational to support MAD. Thus far, its working. A lot of human warfare is on its face is crazy sounding, but has a rational backing.
>when you read about plans like this you just start contemplating about the end of humans as a species.
We called up the USSR and asked them to stop producing weapons on that scale. They laughed in our face. What exactly do you propose? Heck, the USSR's client states were motivated to nuke us without warning. Castro had a pretty big hard-on for launching nukes:
He wasn't convinced by the loss of life or anything. His Moscow handlers had to explain to him that the radioactive cloud would be bad for Cubans. Heck, the politburo was demanding WWIII from Khrushchev during the Cuban missile crisis.
Today, Russia maintains an openly published first strike policy on what it calles "tactical nukes." Essentially they say they can launch nukes whenever they feel like it and not consider it a MAD violation. So if Putin's conventional troops are losing, he just nukes the opposition. With madmen like Putin running nukes, MAD makes sense. Its the only thing that does.
"during Oppenheimer's trial he was the only member of the scientific community to state that Oppenheimer should not be granted security clearance"
"One of the most controversial projects he proposed was a plan to use a multi-megaton hydrogen bomb to dig a deep-water harbor more than a mile long and half a mile wide to use for shipment of resources from coal and oil fields through Point Hope, Alaska."
"Teller suffered a heart attack in 1979, and many observers[71] described him as blaming it on Jane Fonda"
"In the 1980s, Teller began a strong campaign for what was later called the Strategic Defense Initiative (SDI), derided by critics as "Star Wars," the concept of using ground and satellite-based lasers, particle beams and missiles to destroy incoming Soviet ICBMs."
A few megadeaths here-or-there.
The only thing missing from Dr Strangelove is having the uncontrollable hand. Yes, you can call him "just focused" if you prefer that. Let him "peacefully" dig in your backyard.
>One of the most controversial projects he proposed was a plan to use a multi-megaton hydrogen bomb to dig a deep-water harbor
Russians used nukes for mining. Its not magic. You can manage fall-out, risk, etc. Its not "crazy."
>"Teller suffered a heart attack in 1979, and many observers[71] described him as blaming it on Jane Fonda"
A 70+ year old man being a difficult curmudgeon? Say, it ain't so!
> Teller began a strong campaign for what was later called the Strategic Defense Initiative (SDI)
SDI made sense. We still have SDI. Now we call its "Strategic Missile Defense" and its our biggest counter against rogue nation nuke launches and other attacks. It also has Putin scared as he can't match it and is demanding we don't continue to build new sites in Eastern Europe out of desperation.
>The only thing missing from Dr Strangelove is having the uncontrollable hand.
I really wish more people understood the world from the lessons of history instead of caricutures from Hollywood movies.
SDI could be said to plausibly make some kind of sense only in the context of the proposed broad national shield being propaganda to serve as (1) a tool to get the USSR to accelerate its spending in a way that would hasten its collapse, and (2) domestic political cover for more limited shields that would protect key military command and control sites.
If Teller's exuberant promotion of SDI was knowing participation in those propaganda efforts, then it was extremely dishonest but perhaps defensible as not completely nonsensical; on its face, however, it was nonsense.
> We still have SDI. Now we call its "Strategic Missile Defense" and its our biggest counter against rogue nation nuke launches and other attacks.
No, our biggest counter against rogue nation nuke launches is, and remains, a combination of assured destruction of any attacker and active steps to prevent undeterrable actors from gaining the capacity to make such attacks in the first place.
Strategic missile defense of any kind remains, and will for the forseeable future, an extremely limited tool, and far less than SDI was sold as by proponents like Teller.
> It also has Putin scared as he can't match it and is demanding we don't continue to build new sites in Eastern Europe out of desperation.
There's a whole lot I could say about this, but I'll let this suffice: you can't say in one post defend MAD with "With madmen like Putin running nukes, MAD makes sense", and then defend Strategic Missile Defense with the argument that it undermines mad and makes Putin scared and more aggressive.
> SDI made sense. We still have SDI. Now we call its "Strategic Missile Defense" and its our biggest counter against rogue nation nuke launches and other attacks. It also has Putin scared as he can't match it and is demanding we don't continue to build new sites in Eastern Europe out of desperation.
You just basically said that SDI is destabilizing because it will take away MAD. I fail to see how supporting that is rational or sane.
> SDI made sense. We still have SDI. Now we call its "Strategic Missile Defense" and its our biggest counter against rogue nation nuke launches and other attacks. It also has Putin scared as he can't match it and is demanding we don't continue to build new sites in Eastern Europe out of desperation.
That sounds suspiciously like and end-run around MAD, which until close to 100% complete and accurate, seems like it serves to reduce the effectiveness of MAD as a method to prevent nuclear war.
All parties are developing SDI. Its the next arms race. If we stop, we lose MAD. If they stop, they lose MAD. We're a bit ahead, which isn't saying much considering its trivial to launch enough dummy warheads to outstrip our abilities and fool our interceptors. Whoever is doing better with interceptors loses out to the guy who is doing better with work-arounds. Not cut and dried, but having one deployed does save you from rogue nation launches and other scenarios that have nothing to do with MAD.
My hope is that this all gets too expensive and we all get rid of nukes entirely.
You'll note the suspicious absence of a third world war to follow the War to End All Wars and the one that came after it. Some argue that nuclear weapons are directly responsible for this desirable state of affairs.
I guess the scale of the war and whether it deserves the moniker of a World War depends on your geo-political perspective. Both U.S. and Russia, are involved in military operations all over the world, and it's a little silly to call that a "desirable state of affairs" just because they're not fighting each other.
Make no mistake, I'm not carrying water for Teller in this thread or defending Jane Fonda. I do think Teller was sort of a nutcase, and Fonda was definitely a traitor. Frankly we're all lucky to be alive after some of the crap that was done in the name of "strategic defense," and it's indeed tragic that countless victims of the superpowers' proxy wars can't say the same.
But deterring a third world war is not one of those things that's subject to moral relativism. You seriously need to spend some time talking with WWII vets, while we still have them with us.
We are currently living in the most peaceful time in human history. That's an objective fact based on annual deaths from warfare, not a subjective opinion or perspective.
I don't know why you were downvoted. There have been major wars in the past 25 years, the worst probably being the civil war in Congo. (5 million deaths)[1] Let us not even mention Iraq, Afghanistan, Lebanon, Syria, Libya, Liberia, Sierra Leone and presently, Yemen. But in some sense, if two G-7 countries are not fighting each other in their own soil, the war does not "matter". More and more you think, you realize that George Orwell was a prescient genius when he predicted low-level proxy conflicts in faraway regions as a way great powers will seek to maintain patriotic fervour.
It is true that nuclear weaponry might have avoided many direct wars between the nuclear powers, but it has not been an absolute guarantee. There has been a war directly involving nuclear powers - the Kargil conflict between India and Pakistan. [2] Again, among present troubles, Ukraine and Russia both have nuclear weaponry, I suppose.
S/he is being downvoted for being deliberately obtuse, if not outright trolling.
But in some sense, if two G-7 countries are not fighting each other in their own soil, the war does not "matter".
The G-7 countries (along with the other permanent members of the UN Security Council) are the ones who, when they go to war with each other, are EVERYBODY's problem. Every other kind of war is a local issue. It sounds heartless, but nobody in country U gives a hoot about 5 million deaths in an obscure civil war in country C. But if countries R and G get into it, the entire world sits up and takes notice, and for good historical reasons.
Again, among present troubles, Ukraine and Russia both have nuclear weaponry, I suppose.
One of the more awkward aspects of the Ukraine conflict is that Ukraine gave up their nukes willingly after the dissolution of the USSR, based on the promise that they would remain unmolested. So much for Russian promises.
Unfortunately, as long as dictators like Putin are around, we can't afford the risks of unilateral nuclear disarmament. Without MAD, we are all Ukrainians.
> Its rational to support MAD. Thus far, its working.
Since WWII, none of the countries not engaging in MAD (e.g., all those that lack the capacity to do so), including those with no nuclear-power allies, have been attacked with nuclear weapons. So, while none of those engaging in MAD has been either, there is no evidence that MAD is the reason for that. It's Lisa Simpson's tiger-repelling rock all over again.
That's beyond ridiculous. No one has been attacked by nuclear weapons because nuclear weapons have forced our leaders to resort to diplomacy, except when attacking countries that are too small to require nukes. This is, on the whole, a GOOD thing.
Eh, how does a 10Gt bomb support MAD? MAD is mutual assured destruction: it works because both sides have a comparable power. Equipping one side with 10Gt weapons when the other side has "only" 10Mt-level weapons isn't MAD, it's madness.
That is, unless your goal is not MAD at all, but the nuclear destruction of the other side by your side. A prospect that Teller didn't find too horrible, I guess.
> you implement a MAD-like policy or you die in nuclear fire
This assumes that some "other side" is willing to destroy 1/3 of the Earth just to "get you". A ludicrous supposition only believed by hawks and ideologues.
I think Teller was discussing at least once big bombs as a countermeasure against falling asteroid/comet threat. I guess you might actually need a gigaton bomb in a case like that?
Be sure to visit the NUKEMAP simulator and see how the Tsar Bomba matches up to some of the other nuclear warheads available. Drop one on your hometown!
Or the 3d version, which is a bit scary in combination with the 3d building imagery from aerial photography - for my house it's good enough that I can easily make out individual trash bins and features as small as a couple of square feet in my back garden. When you hit the detonate button you get to see the mushroom cloud as well as the blast radius :-/
I've always thought it illustrative to compare the NUKEMAP results for Little Boy and the Tsar Bomba at Hiroshima. It gives a good indication of just how much more destructive and terrifying warheads became: where Little Boy destroyed a city, a 100 Mton Tsar Bomba would have destroyed much of the region, and caused fires on other islands. And for ICBMs, MIRVs meant that even smaller warheads, themselves still vastly larger than Little Boy, could be launched together to have the same or worse destructive effects.
I'm pretty sure if the first atomic warheads had been 10 or even 100 times the size they still would have been used.
After all they could have dialed down 'Little Boy' (what a crap name for a weapon) to a smaller yield too, or dropped it in a less populated area but did not.
I wonder why, depending on the bomb, the radius some radius don't come in the same order. Some time the air blast is larger than the fireball, sometimes not.
One thing that factors into that is the surface vs airburst setting (the presets differ).
edit: for the simulation, the other major thing that factors into it must be the "fission fraction", the presets store 4 things: name, yield, a field marking surface/airburst and the fission fraction.
Soviet union was enclosed by US airbases and nonstop flying bombers, which could hit any city in a few hours. America also developed crazy stuff like Project Pluto...
Anyway there are two reasons for this bomb not mentioned in article:
- Terraforming. Soviets honestly believed they could redirect rivers from north to arid south. They even made artificial valley in mountains as experiment. Larger nukes are cleaner than smaller nukes.
- Doomsday device in form of dirt bomb. Plan was to concentrate all nuclear waste from Soviet countries on single place, and explode massive bomb under it. Explosion would spread nuclear material into atmosphere and most of earth wold become radioactive. This device was not approved by soviet leaders, too dangerous.
There are some good articles that go into a bit more depth on this, specifically on Putin's perceptions of such (or at least his rhetoric to that effect). Here's one from the Jan 31 Economist:
And might be the reason why they are so quick to also help other countries with a similar issue (for example: I am from Brazil, and our navy is crap, when we announced finding one of the largest oil reserves of the world, US immediately announced reactivating their south-atlantic fleet, they don't even tried to hide their intentions... so Russia now patrols our water for us, to keep US ships away from the oil rigs).
The US makes about 8 million barrels a day. The Tupi field discovered off Brazil makes about 100,000 a day and best-case contains a few years of American oil production total.
You think the US Fourth Fleet reactivation was intended to steal that production? And risk war with most of South America?
It's particularly silly when coupled with the "that's why Russia patrols our waters now!" bit. Out of the altruistic goodness of Putin's heart, I suppose?
I was not talking about ONLY the tupi field, but about the entire pre-salt layer, that is sprawled all over our coast (that is too big for our tiny navy to defend).
Geologists (not just brazillian one) expect the pre-salt layer to have 50 billion barrels, that is 4 times Brazil current oilfields, thus why to Brazil it is important.
Also the Tupi field current exploration is more related to a stock market scam than an actual attempt (see Eike Batista and the stunt he pulled...)
The point remains - what are you accusing the US Navy of planning to do along your coast, and what is the Russian navy supposedly doing to prevent it (and why do you assume they have any better motives than the US does)?
The US Navy deactivated the south atlantic fleet decades ago, and then it announced its reactivation shortly after our official announcement of finding lots of oil... Why should we not be suspicious?
And Russia is here because our government invited them, after US announcement, officially it is for "training", but Russian ships can keep US ships away from the oil rigs (ie: when a US ship is in a place the government here disapproves, the government invites Russian ships to do a "training drill" nearby, and push away the US ship, that will retreat to avoid conflict, a sort of psychological dance).
Mind you, US already used its navy to topple our government before (in 1964 it sent a carrier group to support CIA during our military coup), and US was suspected here of having too much interest in our oil company, this later was proved by Snowden (NSA did lots of spying on Petrobras, including of stuff that is more commercial than strategic), so excuse me if we don't trust US, the past behaviour of US toward us here has not been good (while we have nothing but praise for Russia... yes, I know all Russian issues worldwide, but locally to US Russia always had been a great true ally).
That's kind of silly. Fourth Fleet has zero permanently assigned ships, and a peak strength of something like four ships in its area of responsibility, and doesn't, AFAICT, involve any more naval strength typically deployed in the region than US Naval Forces Southern Command had in the region prior to Fourth Fleet being stood up with the same area of responsibility and commander as USNAVSO.
AFAICT, the "intention" of standing up Fourth Fleet as an organization was to bring the naval side of Southern Command HQ structure more in line with that of the rest of the geographical combatant commands (US Naval Forces Africa still doesn't have a numbered fleet or similar command associated, but Africa wasn't yet a full independent unified combatant command at the time Fourth Fleet was stood up in Southern Command.)
Better be safe than sorry... Specially after what US did in 1964 (US sent a carrier group here to support CIA to support a military coup... all that stuff is in declassified files)
In 1964 US forces don't fired a single shot, but they didn't need to, US is so absurdly stronger that they being in our territory is enough to strong-arm us to do anything they want, US and Brazil government know that Brazil government will always yield to US if US is in firing range, precisely for that reason that Brazil government don't like US in firing range, Brazil knows US won't attack out of the blue, and thus this can be used to keep US away (for example keeping Russian ships in firing range instead... US won't suddenly fire on Russian ships, this fact is ALSO known to both governments).
Tsar's destructive force was incredible, but I think it bothers me a lot more that the US built 500 B41 bombs with a 25Mt yield during that era. What's the functional destructive difference between 50Mt and 25Mt? Zilch, any practical target hit by it is gone.
I agree it would be hard to be sure you had gotten every last one, but it would be easy to ensure that the survivors live in a new stone age with nuclear fallout making most of the earth uninhabitable for people, if not most life. I've been somewhat amazed at how resilient the biome around Chernobyl has shown itself to be, but I'm sobered by the measurable losses attributable to it that accident as well.
When I think about human intelligence, my mind always arrives at these scientists.
How can, then, some of the smartest people on Earth be involved in something as stupid as this.
Many scientists realise the grave consequences of their stupidity, after the fact. Both Sakharov and Oppenheimer realised this, but it was too late. The genie was out.
The mirage of power, respect, titles, prizes and access to unlimited resources for their experiments is too strong to resist, I guess. :Carrot
Then there's the patriotism thing - do right for you country, protect it from the enemies. Fear. :Stick
This is how the devil works, after all :).
Beware of the stupid as he knows not what the implications of his activities are.
Be scared of the smart working for the stupid, as he very well knows the implications, but is too weak to resist the temptation. He has sold his soul.
It's your classic Prisoners' Dilemma. (No surprise, since game theory was largely developed to analyze nuclear war.)
You're stuck with another guy. You're both better off if you both cooperate. But individually you're better off if you betray the other guy. In that situation it's really, really hard to arrange cooperation.
The US and USSR would have been better off if they could have put a halt to the madness. But if one stopped, that gives huge incentives for the other to betray.
The thing is, betraying the other is the rational thing to do. It's the worst outcome, but it comes from purely rational actions.
And hilariously, whenever it is tested the whole thing falls flat. Because humans cooperate by instinct. Kennedy was told again and again to escalate until the Kremlin backed down. Eventually he had enough and basically showed "rationality" the door. Thus the Cuban Crisis ended without the cold war going hot.
Well consider the following question, is it crazy to call Nuclear Weapons one of the biggest peace-keeping phenomena of all time?
It appears that because of MAD, sovereignty between Nuclear armed countries is pretty much ensured.
I mean I'm scared to death by Nuclear weapons (intellectually scared, similar to say Global Warming being a gigantic threat), but I can't help but wonder if these things don't prevent a WW3, and force conflicts to be resolved diplomatically, through economic sanctions, cyberwar, through export of ideology or comparatively smaller 'cold war' type conflicts.
e.g. Yemen today is essentially Iran fighting Saudi Arabia for a bit of regional influence in a way without Iran & ally Russia/China actually fighting with Saudi & ally US/West. Conflicts that are all preferable in scale to an all out WW3, which wouldn't happen (on paper) because of MAD due to Nuclear Weapons.
Nukes makes zero sense if it is a resource war, and those are the oldest ones there is.
A influence war also has little use for nukes, as you want those friendly to you to live and thrive afterwards.
As best i can tell the only time using nukes "make sense" is when faced with a enemy that is committed to your total elimination, and that are completely unified in this goal.
The filmmaker behind TAB is Peter Kuran. He was a visual effects specialist for some pretty cool movies (e.g. Empire Strikes Back). Restoring old atomic test footage is a special interest of his and he's also done several more in-depth documentaries about atomic weapons:
Nuclear Rescue 911: Broken Arrows & Incidents
Atomic Filmmakers: Behind the Scenes
Atomic Journeys: Welcome to Ground Zero
Nukes in Space
Atomic Filmmakers is my favorite--it's sort of a "making of" for the historical footage used in the other movies and it talks about the secret Lookout Mountain film studio the Air Force set up outside LA to develop special technology to document and instrument above-ground nuclear tests.
"Interestingly enough, Tsar Bomba was one of the “cleanest” nuclear weapons ever detonated, because the bomb’s design eliminated 97 percent of the possible fallout."
How do one design a bomb to eliminate, or minimize, fallout? I wasn't even aware it was an option.
By my understanding, fallout is less a function of the explosion being nuclear and more of how the bomb is detonated. The Tsar Bomba was an air-burst. By keeping the fireball in the air, less vaporized material from the ground is kicked up into the debris cloud from the blast. Both air bursts and ground bursts generate fallout, but a ground burst will generate nastier, localized fallout, and more of it.
This is my speculation, but I suspect another reason for the relative lack of fallout from the Tsar Bomba was related to its yeild. To get a particularly large yeild from the materials available, the bomb is going to have to be as efficient as you can get it. All things equal, a more efficient system generates less waste.
Or the design the article could simply be referring the bomb's parachute system, which helped keep the blast in the air.
Most of the energy in most H-bomb designs comes from the fission of the uranium tamper around the secondary by neutrons from the fusion of the secondary. Fission is a messy process.
In the "limited" Tsar bomb design they had a non-fissioning secondary tamper so yield was mostly from fusion and the explosion was high enough (i.e. far from the ground or sea) that the fusion neutrons didn't have too much else to activate.
I found the recent series by the Digital Antiquarian to be very interesting on this, weaving together Infocom's Trinity series and the atomic bomb history, including the Tsar Bomba.
I saw a doc about nuclear weapons that mentioned this one and said that the real reason that no one made them bigger was the fact that they were wasteful.
The atmosphere is effectively 10 miles high. Once your blast radius approaches that the difference in pressure pushes most of the energy upward above the atmosphere. You don't get the horizontal spread you'd expect as you increase tonnage.
No seriously... MUCH MUCH bigger then you think.
it was 10 times the combined power of all the conventional explosives used in World War II
it was 10% of the combined yield of all nuclear tests to date.
and mostly.... It was the equivalent of over 1kg of antimatter going up. 1 ^#%$ing kg.... of ^#%$ing antimatter.
It broke windows in Norway and Finland and its shock wave was VISIBLE in the air 700 km away.
It is impossible to get people to understand how much of a monster it was. AND.... and this was it dialed down to 1/2 its maximum yield.
No one has been crazy enough to test another nuke of its size. Even in the height of the cold war no one was crazy enough to test something like that again.
