Abstract
A combination torpedo tube test plug and muzzle door for a torpedo tube iudes a circumferential land formed at an extreme muzzle end of the torpedo tube. The circumferential land has an inner peripheral diameter less than an inner peripheral diameter of the torpedo tube, and an inner peripheral transition surface contiguously joining the inner peripheral surface of the torpedo tube. An abutting face is formed on an end of the muzzle door facing the circumferential land. A lip extension extends from the abutting face. The lip extension includes an outer peripheral surface mating with the inner peripheral surface of the circumferential land, and a device for selectively securing the lip extension to the inner peripheral surface of the circumferential land, wherein separation of the muzzle door from the torpedo tube is prevented.
