Pentagon Document Confirms Existence of Russian Doomsday Torpedo (popularmechanics.com)

Popular Mechanics reports that "a key U.S. nuclear weapons document confirms that the Russian government is developing the most powerful nuclear weapon in more than a half century...a 'new intercontinental, nuclear-armed undersea autonomous torpedo'" with a range of 6,200 miles. But what really makes "Kanyon" nightmare fuel is the drone torpedo's payload: a 100-megaton thermonuclear weapon. By way of comparison, the atomic bomb dropped on Hiroshima was 16 kilotons, or the equivalent of 16,000 tons of TNT. Kanyon's nuke would be the equivalent of 100,000,000 tons of TNT. That's twice as powerful as Tsar Bomba, the most powerful thermonuclear weapon ever tested. Dropped on New York City, a 100-megaton bomb would kill 8 million people outright and injure 6 million more.

Kanyon is designed to attack coastal areas, destroying cities, naval bases, and ports. The mega-bomb would also generate an artificial tsunami that would surge inland, spreading radioactive contamination with the advancing water. To make matters worse there are reports the warhead is "salted" with the radioactive isotope Cobalt-60. Contaminated areas would be off-limits to humanity for up to 100 years.

Slashdot reader schwit1 adds that "being sea-based makes it immune to ballistic missile defense."

      The tsar bomba was designed with a max yield of 100 megatonnes if the jacket material was uranium. But that would cause a huge amount of fallout so they tested it with an inert casing, which made it one of the cleanest nukes ever detonated, proportionally.

Normally, this kind of thing would be classified (we overclassify EVERYTHING, and Russian nuclear capabilities is a legit secret), so a public release likely indicates an attempt to shape policy.

  7. First Strike Weapon by Decapitation? by wisebabo · · Score: 5, Interesting

    At first thought, it would appear that this wouldn't be suited at all as a first strike weapon. Despite the immense damage it would cause, it would not directly cripple a retaliatory strike. The U.S.'s bombers and missiles are far inland and it would only sink the nuclear subs that happened to be in port nearby.

    However, it COULD be used to decapitate much of the the political "leadership" (if one were to call the Trump administration that) and also much of the military leadership if it were detonated right off of Washington D.C. In fact, assuming that it could get close enough to be used (which of course is the only way it could be useful) it would be an almost instantaneous first strike weapon. Unlike a ballistic missile launched from a sub offshore on a depressed trajectory (5 min.?) or a nuke disguised as a satellite that suddenly de-orbits (20 min.?) it would be able to wipe out its target with too little time to escape. That, coupled with a "normal" first strike that would take out the land based bombers and missiles might be enough to keep the retaliation to a minimum. Or in the words of General 'Buck' Turgidson, "10-20 million (casualties) tops. Sure (they'd) get their hair mussed but (they'd) win".

    Insane? Well so is the idea of an autonomous (meaning I presume there's no way to call it back) doomsday torpedo. Sounds like one could remake "The Hunt for Red October" with just a few changes; a robotic submarine capable of ending the world (or just the coast of many large nations) is accidentally launched and it must be found and destroyed before it gets within range (or becomes sentient).

    Since Russia isn't nearly as vulnerable as the U.S. from coastal attacks but seems to be way behind and falling further in space technology (thanks Elon!); why not put a big rock in the sky that, with just a little nudge, would fall down the gravity well and give a non-radioactive 100MT blast? Or, if the Russians are going to go ahead and violate the nuclear arms treaty (I'm pretty sure developing a whole new strategic nuclear weapon system is not allowed), use America's lead in new biotechnologies that could target specific regions or exact populations (I'd tell you how but probably not best to talk about such things publicly).

      I like your use of the word "allow" and the phrase "they won't allow". It's quaint.

      History tells us, and with startling consistency, that wars don't start based on who allows what, they don't play out based on who allows what, and they don't end based on who allows what.

      They start because of brinkmanship (check), territorial ambitions (check) and unexpected, often improbable and generally unanticipated (by both sides) events which lead to ad-hoc responses that weren't in the playbook devised by those who plan for such things.

      They play out in such a way that the weaker employs tactics that negate the stronger's advantages, and the stronger applies force that the weaker doesn't possess. Lord help everyone if there is no demonstrably weaker and stronger side, because then the Shit Really Hits The Fan, and for longer than everyone, often including the eventual losers, would like.

      The latter often means bigger and nastier weapons, often of a type yet deployed in battle, because ... well ... it's a perfect proving ground, there's a justification (to win the war and save {our side's / innocent civilians / the enemy's conscripted soldiers etc} lives ... and interested minds want to know how effective the thing is, and what's the weakness we need to engineer out for the next war, or this one, if it lasts long enough.

      Today we have a complex web of alliances and treaties that tends to prevent big conflicts by addressing small ones, but when the improbable and unexpected happens, that just means you get a bigger war. Throw in some widely held beliefs about the other side (one widely held by America's foes is that the US domestic population can't stand a prolonged conflict and will force political concessions to the enemy), regardless if they are actually true or not.

      Really, I don't see much "allowing" going on. More like stumbling, guessing, thrashing, and suffering. Oh, and let's not forget the best one of all, "testing".

    It's enormous. Way larger than a torpedo tube.

    2) How far away from the launching submarine would 100 Mt warhead need to be? 100 Mt is obviously an enormous amount and explosions under water are more damaging.

    3) How is an 'intercontinental torpedo' propelled? It seems the propulsion system would add more weight to an already heavy concept

    4) How is it guided? GPS won't work because it's underwater. Submarines use all sorts of subtle techniques like passive sonar to avoid revealing their location and ultra low frequency radio transmissions. A human crew on a sub can do this. It's far from clear a drone submarine is viable

    5) Why salt the bomb? That would poison the oceans over a vast area.

    It just sounds like the Russians have leaked this in attempt to make the US give up on missile defence. There's no evidence this project got funded. And Russia is so cash strapped it didn't even an SLBM subs patrolling as recently as 2006. Putin has pushed for new SLBMs and new subs to put them with the result the US no longer has nuclear primacy but that process was not exactly embarrassment free - tests failed for a while.

Both of these guys are monsters, but they are somewhat predictable in that they have motivation to want to keep their money, power, and health intact. They will act to preserve these things first and foremost.

    Any investigation into doomsday weapons will be colored by these motivations. A super torpedo would be very, very slow compared to a ICBM. It would also be very large, and if detected in transit, it would give an opponent quite a bit of time to react. Moreover, there is the Dr.Strangelove problem: Unless you tell everyone about it, it serves as no deterrent so you cannot keep it secret. By telling people about it, you are giving them a first strike target and making it less likely that it will survive to complete its mission. This weapon is also limited to hitting coastal targets, that is quite a limitation.

    This seems like a really expensive and risky weapon to construct. Wouldn't it just be simpler to restart the nuclear arms race, and start cranking out thousands and thousands of more conventional nuclear weapons to saturate anti-missile systems? You only need one or two to connect with a target.
