Underwater speed record

Template:Short description Underwater speed record include records for submarines, autonomous underwater vehicles, and torpedoes. As these are typically for military vehicles, most are unconfirmed.

The Template:USS, with its teardrop hull, is claimed to have reached an underwater speed of Template:Convert.

Submarines

Established reports and manufacturer's claims indicate that a handful of submarines are capable of speeds exceeding Template:Convert. In 1960, HMS Explorer S30 achieved an underwater speed of over 30 knots. In 1965, the experimental Template:USS reported a speed of Template:Convert. The Soviet Template:Sclass2 was found in 1968 to have a speed of Template:Convert. In response the United States Navy developed the Template:Sclass, with a reported speed of Template:Convert. The Template:Sclass (Russian: shark)-class vessel is reportedly capable of travelling submerged at Template:Convert. Its predecessor, the Template:Sclass, could attain short speed bursts of Template:Convert while submerged. There are also claims that the Soviet twin-propeller submarine K-222, with titanium inner and outer hulls, reached Template:Convert, fully submerged, during sea trials in 1969.

Torpedoes

The British Spearfish torpedo, designed to counter high-speed Russian submarines such as the Alfa class, is reputed to reach speeds in excess of Template:Convert. The Russian VA-111 Shkval rocket-powered supercavitating torpedo is reportedly capable of speeds over Template:Convert. The German press reported on an underwater anti-torpedo missile, formerly named Barracuda, allegedly capable of reaching Template:Convert.
