ABSTRACT:
An underwater launch system includes a launch tube frangibly sealed at its forward end. At launch time, pressure equalization means introduces water at depth pressure into the launch tube between its frangibly sealed ends. A rotary electromagnetic pump coupled to the launch tube receives water at depth and expels the water at a higher pressure. The higher pressure water is coupled to the aft end of the launch tube.
