Mark 35 torpedo

The Mark 35 torpedo was the first of the United States Navy deep-diving anti-submarine torpedoes designed for surface launch.^[2] This electrically propelled 21-inch (53-cm) torpedo was 162 inches (4.11 m) long, weighed 1770 lb (803 kg), and carried a 270 lb (122.5 kg) Torpex high explosive warhead.^[3] This torpedo used one of the earliest active guidance systems and was introduced in 1949, and was classified as obsolete in the 1960s.^[2]

The Mark 35 torpedo was originally specified as the intended payload for the Grebe missile, before being replaced by the Mark 41 due to weight concerns.^[4]

Mark 41 torpedo

A simplified and lighter weight version of the Mark 35 was developed, specifically for air-launched use. This eliminated any equipment not needed for air-launching, saving 450 lbs. ^[5] The nose also became distinctively flat-fronted.

This torpedo was used as the payload in some ASW missiles, the AUM-N-2 Petrel and the SUM-N-2 Grebe.
