Post by aukepalmhof » Tue Mar 16, 2021 7:45 pm

The Foxtrot class or Project 641 was built between 1957 and 1983 by the Sudomeku yard in Leningrad for the Soviet Navy.
The class was in service between 1958 and 2014.
Displacement 1,983 ton surfaced, 2,515 ton submerged, dim. 89.9 x 7.4 x 5.9m (draught surface).
Powered by 3 Kolomma 2D42M 2,000 hp (1,010 kW) diesel engines, 3 shafts, speed 16 knots surface, on snorkel 9 knots. Three electric motors two 1,350 hp (1.010 kW) and one 2,700 hp (2,000 kW). Speed submerged 15 knots.
Range 20,000 mile by a speed of 8 knots, surface and 11,000 miles when snorkeling, 380 mile by 2 knots, submerged.
Endurance 3 – 5 days submerged.
Test depth 246 – 296m.
Crew 12 officers, 10 warrants and 56 seamen.
Armament 10 torpedo tubes (6 bow, 4 stern), carried 22 torpedoes.

The Foxtrot class was the NATO reporting name of a class of diesel-electric patrol submarines that were built in the Soviet Union. The Soviet designation of this class was Project 641. The Foxtrot class was designed to replace the earlier Zulu class, which suffered from structural weaknesses and harmonic vibration problems that limited its operational depth and submerged speed. The first Foxtrot keel was laid down in 1957 and commissioned in 1958 and the last was completed in 1983. A total of 58 were built for the Soviet Navy at the Sudomekh division of the Admiralty Shipyard (now Admiralty Wharves), Saint Petersburg. Additional hulls were built for other countries.
The Foxtrot class was comparable in performance and armament to most contemporary designs. However, its three screws made it noisier than most Western designs. Moreover, the Foxtrot class was one of the last designs introduced before the adoption of the teardrop hull, which offered much better underwater performance. Also, although the Foxtrot was larger than a Zulu class submarine, the Foxtrot class had 2 of its 3 decks dedicated to batteries. This gave it an underwater endurance of 10 days, but the weight of the batteries made the Foxtrot's average speed a slow 2 knots at its maximum submerged time capability. Due to the batteries taking up 2 decks, onboard conditions were crowded, with space being relatively small even when compared to older submarines such as the much older American Balao-class submarine. The Foxtrot class was completely obsolete by the time the last submarine was launched. The Russian Navy retired its last Foxtrots between 1995 and 2000; units were scrapped and disposed of for museum purposes. During the division of the Soviet Black Sea Fleet, in 1997 one Foxtrot class submarine (later renamed as ZAPORIZHZHIA) was passed to Ukraine as it was not operational since 1991. The ship never effectively served in the Ukrainian Navy and was under repair. In 2005 Ukrainian Ministry of Defence wanted to sell it, but was unsuccessful. Following successful post-repair trials in June 2013, it was recognized as operational. However, on 22 March 2014, it was surrendered to or captured by Russia as part of the Russian annexation of Crimea Russia decided not to accept it due to its age and operational unsuitability. Its subsequent status is unknown.


Cuban Missile Crisis
Foxtrots played a central role in some of the most dramatic incidents of the Cuban Missile Crisis. The Soviet Navy deployed four Foxtrot submarines to Cuba. US Navy destroyers dropped practice depth charges near Foxtrot subs near Cuba in efforts to force them to surface and be identified. Three of the four Foxtrot submarines were forced to surface, one eluded US forces.
