A mechanical interlock system is disclosed having an interlock segment that is mechanically coupled to the breech door, to the slide valve, and to the muzzle door of an associated torpedo tube in such a way that the interlock segment positively prevents opening, or the initiation of the opening sequence, of the breech door if either the corresponding muzzle door or slide valve for a particular torpedo tube is open, and that positively prevents opening, or the initiation of the opening sequences for, either the corresponding slide valve or muzzle door of a particular torpedo tube, if and as soon as the breech door is free to open, is opened or if its opening sequence is once initiated. The interlock segment and mechanical coupling of the interlock system of the present invention exhibits improved breech door stress performance and reduced manufacturing, inventory, repair and other costs.
