The '''Mark 35 torpedo''' was the first of the United States Navy deep-diving anti-submarine torpedoes designed for surface launch.{{sfnp|Kurak|1966|page=145}} This electrically propelled 21-inch (53-cm) torpedo was 162 inches (4.11 m) long, weighed {{convert|1770|lb|kg}}, and carried a {{convert|270|lb|kg|adj=on}} HBX warhead.{{sfnp|DiGiulian|2008}} This torpedo used one of the earliest active guidance systems and was introduced in 1949, and was classified as obsolete in the 1960s.{{sfnp|Kurak|1966|page=145}}
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.{{sfnp|Parsch|2003}}
== 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, with a total mass of {{convert|1327|lb|kg}}. The warhead filler was reduced to a mass of {{convert|150|lb|kg}}. <ref>{{cite web |last= Jolie |first = E.W. |title = Torpedo Mk41 |work=A Brief History of US Navy Torpedo Development | url= https://www.maritime.org/doc/jolie/part2.htm |ref={{harvid|Jolie|1978|41}} }}</ref> 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''.
