Mk 13 Illustration of Torpedo Mk 13 Service 1936-1950

The Torpedo Mk 13 was the first torpedo designed specifically for aircraft launching. Developed by the Naval Torpedo Station, Newport, R.I., approximately 17,000 of these antisurface ship torpedoes were produced during World War II. Among the producers were the Naval Torpedo Station; Pontiac Motor Division, Pontiac, Mich.; the Amertorp Corp., Forest Park Ill., and St. Louis, Mo.; and the International Harvester Co. The Mk 13 torpedo saw service during the second World War and was eventually outmoded by ASW torpedoes.

Mk 24 Illustration of Torpedo Mine Mk 24 Service 1942-1948

Called a mine for security reasons, the Mk 24 was developed as an outgrowth of work on an underwater listening device sponsored by the Naval Defense Research Committee during World War II. This torpedo, with a small warhead, was a crippling weapon designed for "mission kill" vice "platform kill." Approximately 4000 of these aircraft-launched, passive acoustic, antisubmarine torpedoes were produced and in service during World War II and subsequent years until replaced by Torpedo Mk 34. Mine Mk 24 was developed by a group of activities including Western Electric Co., Kearney, N.J.; Bell Telephone Laboratories, Murray Hill, N.J.; Harvard University Underwater Sound Laboratory, Cambridge, Mass.; and General Electric Col Schenectady, N.Y. The Western Electric Co., Kearney, N.J., and General Electric Co. in Erie and Philadelphia, Pa. were the producers.

Mk 34
Mod 1
Illustration of Torpedo Mk 33 Mod 1 (Mine Mk 44) Service 1948-1958

The Torpedo Mk 34 Mod 1 (initially designated Mine Mk 44), was an improved version of Mine Mk 24, used magnetrostrictive hydrophones in lieu of crystal hydrophones. It also used two propulsion batteries in a parallel/series switching arrangement which provided for longer search time/range and a shift to higher speed during attack after acquisition. Developed by the U.S. Mine Warfare Test Station, Solomons, Md., approximately 4050 were produced during the period from 1948 through 1954. The main producers of this torpedo were the American Machine and Foundry Co., Buffalo, N.Y.; the Naval Ordnance Plant, Forest Park, Ill.; and the Naval Mine Depot, Yorktown, Va. In-service in ASW aircraft for many years, this torpedo was withdrawn from Fleet use with the introduction of Torpedo Mk 43.

Mk 43
Mod 0

The Torpedo Mk 43 Mod 0 was an aircraft-launched ASW torpedo. It was developed and produced by the General Electric Co., Pittsfield, Mass., to provide a lightweight, inexpensive torpedo for ASW use from fixed- and rotary-wing aircraft and airships. Approximately 500 of these torpedoes were manufactured for evaluation purposes but were discontinued in favor of Torpedo Mk43 Mod 1 & 3.

Mod 1 Mod 3

The Torpedo Mk 43 Mods 1 and 3 were developed by Brush Development Co., Cleveland, Ohio, and the Naval Ordnance Test Station, Pasadena, Calif., during the post-World War II years. This was the first lightweight, antisubmarine torpedo capable of being launched by helicopters, fixed-wing aircraft, and surface ships. Approximately 5000 of these torpedoes were produced by the Brush Electronics Co., Cleveland, Ohio, and the Naval Ordnance Plant, Forest Park, Ill., from 1951 through 1959. This torpedo was withdrawn from Fleet use after the introduction of the Mk 44 torpedo.

Mk 44 Illustration of Torpedo Mk 44 Service 1957-1967

The Torpedo Mk 44 was a second-generation, lightweight ASW torpedo and the first service torpedo with a seawater-activated battery as a power source. This torpedo, the replacement for Torpedo Mk 43, had improvements in speed, warhead size, acoustic homing capabilities, and prelaunch-selectable search parameters. The Mk 44 was developed by the Naval Ordnance Test Station, Pasadena, Calif., and the Aeronautical and Ordnance Systems Division of the General Electric Co., Pittsfield, Mass. Production was started in 1957 at G.E., and in succeeding years at the Naval Ordnance Plant, Forest Park, Ill., and at the American Machine and Foundry Co., Buffalo, N.Y. Torpedo Mk 44 was used in service on U.S. destroyers and aircraft as an ASW weapon for about ten years until it was replaced by Torpedo Mk 46. In addition to being purchased by foreign governments under the Military Assistance Program, the Mk 44 torpedo was produced in Europe by NATO countries

Mk 46 Illustration of Torpedo Mk 46 Service 1963 - >>

Developed by the Naval Ordnance Test Station, Pasadena, Calif., and Aerojet General, Azusa, Calif., the Mk 46 torpedo is a third-generation, lightweight ASW weapon. It is powered by a thermal piston engine and is capable of higher speed, longer range, better acoustic performance, and deeper depth operation than its predecessors. (Torpedo Mk 46 Mod 0 uses a solid propellant grain while the Mod 1 uses liquid monopropellant fuel. The Mod 1 performance in speed and range is better.) Torpedo Mk 46 production began at Aerojet General in 1963 and in the next two years production commenced at the Naval Ordnance Plant, Forest Park, Ill., and at Minneapolis Honeywell Inc., Hopkins, Minn. The Mk 46 torpedo is currently in service on U.S. Navy destroyers and aircraft and has been purchased by foreign governments under the Military Assistance Program. The torpedo will continue in service until replaced by a new generation lightweight ASW torpedo.
