The G7es (TV) "Zaunkönig" (''wren'' in German) was an acoustic torpedo employed by German U-boats during World War II. It was known as the GNAT (German Navy Acoustic Torpedo) to the British. == Description == The forerunner of the TV was the G7e/T4 Falke, codename "Falcon," which was introduced in March 1943, but only fired by three U-boats by September of that year when the G7es (which was faster, had more range, possessed a magnetic exploder and could also be equipped with a percussion pistol) became available. The torpedo was electric and had an effective range of 5700 metres at a speed of 24 knots (44 km/h). This torpedo employed passive acoustic homing to find its target, becoming active after a straight run of 400 metres. The homing mechanism consisted of two hydrophone receivers which sensed the sound waves of ship propellers and altered the direction of the rudder via an electropneumatic device. There were three variants: * Two flat-nosed versions which contained four sets of magnetostriction hydrophones. * A round-nosed version which contained two magnetostriction hydrophones inside a funnel-shaped baffle. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「G7es torpedo」の詳細全文を読む スポンサード リンク
