Torpedo Tube Assemblies Mk 32 Mods 5 and 7 are pneu- matic launching devices capable of receiving, stowing, and launching Tor- pedoes Mk 44 Mod 1 and Mk 46 Mod 1. The

13、tube assemblies consist of three parallel barrels in triangular configuration, with three Breech Mechanisms Mk 1 Mod $ and torpedQ securing mechanisms, each an integral part of the barrels which are nested together on a common Training Gear Mk 11 Mod 1. Each barrel is capable of being selected and f

14、ired electrically from a remote location and of being manually fired at the tube in an emergency condition, During manual firing, a latch plate is swung open to provide automatic switching from normal to emergency torpedo gyro squib fire power for Torpedo Mk 46 Mod 1 and expose a manual firing butto

A charging line stowage tube is mounted on the uppermost barrel to accomodate the flexible charging hose. The only difference bet

17、ween the Mods 5 and 7 is in the electrical circuits: the Mod 5 is compatible with Fire Control Systems Mk 102, 105, and 111; the Mod 7 is compatible with Fire Control System Mk 114.
