From Wikipedia, the free encyclopedia
Mark 32 Surface Vessel Torpedo Tubes (SVTT). The Mk 32 system consists of a pair of launchers fitted to warships, each launcher carries three tubes capable of discharging a lightweight torpedo such as the Mark 46 torpedo. Designed for close-in anti-submarine action, the weapon is propelled from its tube by compressed air contained in a flask at the rear of the tube.
