Aerial torpedo

The idea of dropping lightweight torpedoes from aircraft was conceived in the early 1910s by Bradley A. Fiske, an officer in the United States Navy.

[4][5] Fiske worked out the mechanics of carrying and releasing the aerial torpedo from a bomber, and defined tactics that included a night-time approach so that the target ship would be less able to defend itself.

However, the United States Congress appropriated no funds for aerial torpedo research until 1917 when the U.S. entered into direct action in World War I.

[15][16] In December 1914, Squadron Commander Cecil L'Estrange Malone commented following his participation in the Cuxhaven Raid that "One can well imagine what might have been done had our seaplanes, or those which were sent out to attack us, carried torpedoes or light guns.

"[17] On 12 August 1915 a Short Type 184, piloted by Flight Commander Charles Edmonds, was the first aircraft in the world to attack an enemy ship with an air-launched torpedo.

His formation mate, Flight Lieutenant G. B. Dacre, sank a Turkish tugboat after being forced to land on the water with engine trouble.

[5] Later in 1917, the U.S. Navy began to perform trials using a 400-pound (180 kg) dummy torpedo that, in the first test, porpoised from the water back into the air and almost hit the aircraft that dropped it.

[10] Several British torpedo bombers were built, including the Sopwith Cuckoo, the Short Shirl and the Blackburn Blackburd, but a squadron was assembled so late in the war that it achieved no successes.

Even so, Japanese tactical experts predicted that, against a battleship, the attacking force would score hits at only one-third the rate achieved during peacetime exercises.

In the course of the chase of the German battleship Bismarck, torpedo strikes were attempted in very bad seas, and one of these damaged her rudder allowing the British fleet to catch her.

At the beginning of World War II, Germany was making only five aerial torpedoes per month, and half were failing in air-drop exercises.

In April 1942, Adolf Hitler made the production of aerial torpedoes a German priority, and the Luftwaffe took the task over from the Kriegsmarine.

The nose covering absorbed enough of the kinetic energy from the torpedo hitting the water that recommended aircraft height and speed were greatly increased to 2,400 feet (732 m) high at 410 knots (760 km/h; 470 mph).

[23] In 1941, development began in the United States on the FIDO, an electric-powered air-dropped acoustic homing torpedo intended for anti-submarine use.

[24] During World War II, U.S. carrier-based torpedo bombers made 1,287 attacks against ships, 65% against warships, and scored hits 40% of the time.

[27] The Helmover torpedo, a five-ton guided weapon launched from a heavy bomber, was developed by the British Ministry of Aircraft Production for use against enemy shipping, but its introduction in 1945 meant that it was not used in action.

[29] During the Korean War the United States Navy successfully disabled the Hwacheon Dam with aerial torpedoes launched from A-1 Skyraiders.

[30] Since the advent of practical anti-ship missile technology, pioneered in World War II with the MCLOS-guided Fritz X as early as 1943, aerial torpedoes have largely been reduced to use in anti-submarine warfare.

At the peak of the Falklands War, the Argentine Air Force, in collaboration with the Navy, outfitted an FMA IA 58 Pucará prototype, AX-04, with pylons to mount Mark 13 torpedoes.
