Do modern torpedoes still need a tension-wire system when dropped from aircraft?
Short answerThey usually use parachutes, with gyroscopes and self-righting systems helping stabilize the weapon after release at higher aircraft speeds.
NotesModern air-dropped torpedoes usually use parachutes to manage descent from faster aircraft. Gyroscopes and self-righting systems help the weapon settle into its intended attitude. These arrangements replace the tension-wire method used by earlier torpedo bombers.
