The Mark 35 torpedo was the United States Navy’s first deep-diving anti-submarine torpedo designed to be launched from ships. It is a 21-inch diameter electric torpedo, about 162 inches long and weighing 1,770 pounds. It carried a 270-pound HBX warhead and could reach up to 27 knots, with an effective range of about 15,000 yards. Guidance was provided by an early active system using a gyroscope and helix search, and it used a Mk 19 Mod 3 contact exploder for detonation. The Mark 35 was designed by General Electric, produced from 1949 to 1952, and about 400 were built; it was in service from 1949 to 1960.

Originally, the Mark 35 was planned as the payload for the Grebe missile, but weight concerns led to the newer Mark 41 replacing it for that role. A lighter version was developed for air launch, reducing weight to about 1,327 pounds and warhead to 150 pounds, with a flat-front nose. The Mark 35 also served as the warhead payload in some ASW missiles, such as the AUM-N-2 Petrel and SUM-N-2 Grebe.
