533mm Torpedo

The Soviets produced a wide variety of torpedoes for use against surface and submarine targets, and their boats tended to carry a few of each type. While nuclear armed versions used to be common, current treaties have pretty much eliminated such devices. While shorter legged than their Western counterparts, Soviet-designed "fish" tend to be just as fast (60+ Knots) and have fairly good guidance, especially when in a wire-guided mode from a launching platform. The end of the Cold War and a need for hard cash have made the Russians sell even their best designs, something the US and British have not done with the ADCAP and Spearfish.
