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 was laid down in 1957 and commissioned in 1958 and the last was completed in 1983. A total of 60 were built. Most saw service in the Soviet Navy. Foxtrots were also built for the Indian (8 units, from 1967 to 1974), Libyan (6 units, from 1978 to 1980), and Cuban (3 units, from 1978 to 1983) navies[1]. Some Soviet Foxtrots later saw service in the Polish, North Korean and Ukrainian navies. The Soviet Navys Project 611, also known by their NATO reporting name of Zulu class, were designed as attack submarines, but six were converted to become the worlds first ballistic missile submarines, one armed with a single F-11FM Scud missile and five others with two Scuds each. ...

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. 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[2], although some may still be in service with other nations.
