The 10" Mark 43 torpedo was the first and smallest of the United States Navy light-weight anti-submarine torpedoes. This electrically propelled 10-inch (25-cm) torpedo was 92 inches (2.3 m) long and weighed 265 pounds (120 kg).[2] Described as "a submersible guided missile",[3] the torpedo was designed for air or surface launch. The Mod 0 configuration was designed for launch from helicopters or fixed-wing aircraft, and the Mod 1 configuration was for helicopters only. Both were electrically driven and deep-diving, but had relatively short range. They were classified as obsolete in the 1960s.[2]

The Royal Navy purchased fifty examples of the Mark 43 in favour of an improved version of their 18 inch Mark 30 "Dealer B"
