[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.

[4] 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.

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