I just watched 2020 doc on Sea Power, and they ended with Putins Poseidon and more current info says its now called Status 6 poseidon.
The doc shows it being hard to detect traveling any where on earth being nuclear powered, and taking out NY city creating a radio-active waste land of much of eastern USA, because of it 2 or more megaton nuular weapon and create a tsunami to futher knock east coast of USA.
.."....V’s Dmitry Kiselyov: He says his country’s Poseidon nuclear underwater
drone could cause a tsunami that would ‘plunge the British Isles into
the depths of the sea” and turn them into a ‘radioactive desert’ (with
subs).”...
And this link is more telling about Posiedon.
....." This UUV can
carry a nuclear warhead with a blast yield of 2 MT. Though it is
possible that the blast yield could be more powerful. This UUV
reportedly has a range of 5 200 nautical miles (10 000 km). In 2019
Russian news agencies reported that Poseidon uses supercavitation
and can reach underwater speed of a whooping 108 knots (200 km/h).
That's significantly faster than torpedoes can travel. Furthermore
it is planned that Poseidons will operate at depths of 1 000 m,
making them difficult to intercept. Furthermore there are some
indications that this UUV can operate under Arctic ice pack, where
it is much harder to detect and engage. So considering its
capabilities the Poseidon UUV can be a tough nut to intercept. "...
Humanities problem is obvious and this one for secular martin who does not know what to do with my end-date-for -humanity 2232 aprox.
The largest nuclear bomb ever exploded was: Tsar Bomba......The bomb was built in 1961 by a group of Soviet physicists that notably included Andrey Sakharov. At the time the Cold War between the U.S.S.R. and the United States had grown increasingly tense. Meant to be a show of Soviet strength, the three-stage bomb was unparalleled in power. It had a 100-megaton capacity, though the resulting fallout from such a blast was considered too dangerous for a test situation.
Thus, it was modified to yield 50 megatons, which was estimated to be
about 3,800 times the strength of the U.S. bomb dropped on Hiroshima during World War II. "....
And here is Russia release of classified video of the Tsar Bomba blast 1961
