An impulse tank is provided in the free flood compartment of a submarine to pressurize a launcher tube from sea water that has been pumped into the tank for this purpose. The tank is defined in part by the submarine hull and in part by a diaphragm bladder that is designed to expand into the free flood compartment during this pressurization.

A submarine hull comprising: inner and outer hulls defining a free flood compartment therebetween, at least one cylindrical launch tube having a muzzle end defined by the outer hull and having a breach end defined by the inner hull and having an intermediate portion provided in the free flood compartment; an impulse tank defining an opening into each said launch tube between said muzzle end and said breach end, said opening being located closer to said breach end of the said tube so as to be positioned behind a projectile provided in the tube; a slide valve associated with said opening to selectively connect said impulse tank to said launch tube, said impulse tank defined in part by said submarine hull; elastomeric bladder means also defining in part said impulse tank; and pump means having a suction side and a discharge side the suction side being connected to said free flood compartment and the discharge side being connected to said impulse tank and more particularly to said hull defined portion thereof; whereby liquid can be pumped from said free flood compartment into the interior volume of said impulse tank thereby distending said elastomeric bladder means so that opening said slide valve releases pressurized fluid from the impulse tank into the launcher tube.
