“Jive” at Sub Brief here http://youtu.be/45yXkHdYkLU?t=2m8sand below, provides new insights into Russia's giant torpedo:
5:10 Earlier, in 1953-54 the T-15 giant, 40 ton, 1,500mm diameter strategic nuclear torpedo had been considered . Soviet Navy decided they did not need it.
7:10 October 2001 Putin revives the giant torpedo idea
8:00 The B-90 SAROV a modified Kilo SSK appeared to have major changes for something unknown
9:45 November 2015 an illustration of a very large nuclear warhead torpedo accidently/on purpose revealed. Like the old T15 it seemed to be 1,500mm in diameter. Something new - it was to be nuclear propelled.
10:45 March 2018 the STATUS-6 POSEIDON torpedo revealed. Later called “Kanyon” by the CIA. 1.6m diameter, 24m long which can remain at sea “months at a time” and other distressing facts.
13:20 There is a stealth variant of STATUS-6 and to be a noisy super-cavitating variant
14:10 Two Russian submarines MAY eventually be able to launch STATUS-6s
15:00 Jive claims no counter to the threat yet, in part because it is an autonomous drone (ie. AUV) and long term nuclear propelled that can dive deeper than manned subs and deeper than deep diving torpedos (to sink a STATUS-6)
16:10 Its a global weapon.
16:25 It was tested from the SAROV in 2016. Russia may build 30 such AUVs which could “patrol” for months without submarine or other support.
