"Poseidon" Nuclear-armed Underwater Drone

hmm I thought that if name is multifunctional system (look at Rubin's picture you quoted , Putin's presentation where it explicitly targeted CSG or whatever thsy all ac groupings. Nuclear high yield warhead is AFAIK also an option
....

Why would you need 100MT salted warhead for carrier group when 2MT standard one would do just fine?

It's just like every single nuclear weapon ever: on paper they only target military facilities but everyone knows what real targets are.

Ture about PR but who told us that 100Mt is the only option? CSG is viable target. Cost is billions of USD and thousands of people with strategic value. Costs are almosgt 2 orders of magnitude less... I still dont buy only 100MT option + coastal stuff.

PapaDragon wrote: They already have naval nukes for taking out CSGs, they had them since 60s and in all sizes and launch systems.

They don't need massive nuclear torpedo for that when they already have supersonic missiles and loads of standard and supercavitating torpedoes with nukes all tested and in service.

Literally only purpose for this drone is to kill cities, have you seen size of that thing? It's twice the length of Bulava.
Specialized sub just for this? That's 100MT + Cobalt. Nothing else would make sense.

The moment you nuke US aircraft carrier they nuke your city
There is no limited nuclear war, it's a myth for Cold War era cannon​ fodder

And they have Kinzhal with 2000km range, Mach 10 speed, nuke warhead and fraction of a cost that is launched from cheap interceptor

According to this Sutton guy the Sarov was the test boat for the Poseidon. Now they are refitting the Belgorod and building the Khabarovsk. There is also the possibility that Podmoskovye (Delta IV) could be used to carry one.

Its always better to lose one carrier group than you entire country.

Megatsunami
The second most striking factor is the creation of artificial megacuns with a wave height of 300-500 meters with the arrival of waves on the mainland, provided the plain is up to 500 km. [37]

The most serious and complete analysis of the problem of the formation of waves from nuclear explosions is given in the official Pentagon study "Water Waves Generated by Underwater Explosions" . [38] Summarizing the different theories, the researchers gave a table of wave heights for nuclear explosions of different power and at different distances from the explosion point under ideal conditions for wave formation. Thus, for an underwater explosion of 100 MT power, the wave height at different distances from the epicenter will be:

d = 9.25 km, - 202 ... 457 m;
d = 18.5 km, - 101 ... 228 m;
d = 92.5 km, - 20 ... 46 m;
d = 185 km, - 10.1 ... 22 m;
d = 925 km, - 2,0 ... 4,6 m.

If those numbers are accurate you don't need many to wipe out a complete country. Freakin' scary little torpedo...

Khabarovsk is the platform for this weapon. Since they will need more than one you could say it is about to become lead ship of ''Khabarovsk-class''.

Belgorod and Podmoskovye already have their duty roster full, they will not be carrying Poseidon.

Huge. And that is a much smaller one than the warhead supposed to be placed in the Poseidon. If you success amplifying the volume of water displaced by destabilizing a tectonic fault (like i.e. Cascadia) we talk about effects nothing short of biblical. We humans are really freaks of nature

Operation Crossroads, explosion test bomb Baker on Bikini > 4000 times smaller (23kt). It was on 27 meters deep though. Not all ships were sunken but were so high radioactive they needed AFAIK more then one year to do something about it.  

As for tsunami. Meh no 500m only 457 m (1500 ft ))
Calculations I put there were from US Pentagons scientific analysis, you can download form wiki link.  It was from 1996 by the-way...

That is a dwarf bomb in comparison! It definitely looked a swallow, small explosion. Deeper explosion would send less water in the air and displace much more volume...

Yeah, the source of the calculations seems quite ok, Russians should take care not to flatten their own coast when using that weapon on enemy shores
