Russia's not for export Advanced Fizik-2 aka "Futlyar" Torpedo - Part Two

Following yesterday's article - the Soviets, now Russians have been developing heavyweight torpedos since at least the 1930s.

Older Russian Type 53 (530mm) torpedos were limited by their fuel type to a range of less than 20km. The Fizik-1s (aka UGSTs) and Fizik-2s (aka Futlyar) torpedos use Otto Fuel II perhaps giving them a range of up to 60km.

If the Russians have followed the US Mark 48 evolution the Russian Fiziks are likely to be effective at progressively shallower and deeper depths.

The Russian Navy Fizik-2 believed to be capable of a top speed of 60 knots. Compared with the Fizik-1 the Fizik-2 features improved homing systems (perhaps including heat seeking) remote control system and maybe longer range.

Unlike the Fizit-1 the Fizik-2 is probably Russian use only, ie. not available for export. This follows a typical domestic use vs export capabilities demarcation of not selling the latest military secrets. It will be interesting to see if China offers Russia enough money to buy some Fizit-2s - for subsequent Chinese reverse engineering-then production.

The Fizik-2 can be released by both surface fighting ships and submarines engaging both platforms from safe ranges. The Fizik-2 torpedo test program was completed by the Russian Navy by the end of 2017 with the new weapon being deployed from 2018.

A Fizik-2 might need an effective depth as deep as 1,000m to hit the US deepest diving Seawolf class SSNs/Special missions.
