The Mark 32 Triple Torpedo Tube (TTT) launcher allows cruisers and destroyers to participate directly in anti-submarine warfare, hunting down submarines with acoustic homing torpedoes. The Mark 32 uses a pneumatic ejection system to launch torpedoes away from the sub-hunting ship and into the sea.
The Mark 32 Triple Torpedo Tube launcher was an easy way to quickly boost anti-submarine firepower. The system consists of three fiberglass-reinforced polyester resin torpedo tubes bundled together on a swivel mount, each of which contains a Mk. 46 Mod 5A(S) lightweight antisubmarine torpedo.
