Today, acoustic torpedoes are mostly used against submarines.Īcoustic homing torpedoes are equipped with a pattern of acoustic transducers on the nose of the weapon.
Since its introduction, the acoustic torpedo has proven to be an effective weapon against surface ships as well as serving as an anti-submarine weapon. About 204 torpedoes were launched against submarine targets, with 37 Axis submarines being sunk and a further 18 damaged. Navy in March 1943, and it scored its first verified combat kills in May 1943. On the Allied side, the US Navy developed the Mark 24 mine, which was actually an aircraft launched, anti-submarine passive acoustic homing torpedo.
The T5 first saw widespread use in September 1943 against North Atlantic escort vessels and merchant ships in convoys. Few of these torpedoes were actually used and quickly phased out of service in favor of the T4's successor, the G7es T5 Zaunkönig torpedo in August 1943. The Germans developed the G7e/T4 Falke, which was first deployed by the submarines U-603, U-758 and U-221 in March 1943. The first passive acoustic torpedoes were developed nearly simultaneously by the United States Navy and the Germans during World War II. Acoustic torpedoes are usually designed for medium-range use, and often fired from a submarine. When the sound is "equal" on both sides, the torpedo will follow a straight path until it reaches its target.Īn acoustic torpedo is a torpedo that aims itself by listening for characteristic sounds of its target or by searching for it using sonar ( acoustic homing).
It will then issue a command to turn towards the target. Two acoustic transducers will react upon sound and the torpedo will detect that the signal comes from one of the side.
