The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance.
Additionally, beginning in the mid-1960s, there was a project for a Mark 31 aerial torpedo successor to the Mark 30, designed to surpass the Mark 44. This project would be cancelled in 1971 in favor of purchasing the Mark 46. [8] A Mark 30 exhibit in Hangar 4 of the RAF Museum. Specifications: [9] [6] Mark 30 Mod 0. Entered service: 1954

US Mk 44 torpedoes were purchased for the Royal Navy in the 1960s to fill this role, and later replaced by US Mk 46 torpedoes.
