Mark 41 torpedo
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 1327 lb. The warhead filler was reduced to a mass of 150 lb. 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.
