A torpedo launcher for a submarine, wherein the torpedo tube is encircled a cylindrical enclosure and a sack is disposed in the cylindrical enclosure and the sack is in fluid communication with the breech end of the torpedo tube. The torpedo tube and sack are filled with seawater and pressurized air is rapidly supplied to the cylindrical enclosure to eject the torpedo from the torpedo tube.

Torpedo launcher

A launching mechanism is provided for ejecting a small buoy from a high sd deep depth submersible. The buoy is held in place and constrained by a pair of latch levers that lock into a groove in the buoy tail piece. The latch levers are held in place by locking pins. On launch a solenoid valve is operated allowing ambient sea pressure to actuate a release system. The sea pressure retracts a release piston assembly to which the locking pins are attached. Upon withdrawal of the locking pins, the latch levers are released by the force of neg'ator ejection springs. The ejection springs accelerate an open ended cage containing the buoy through a four foot displacement. The buoy strikes a plunger actuating a muzzle plug release mechanism that permits ejection of the buoy from the launch cage.
