Abstract : An apparatus for providing a pressurized liquid to a launch tube for launching projectiles into a liquid medium. The device comprises an elastomeric bladder disposed inside a cylindrical bypass tube. The forward end of the bypass tube is open to the liquid medium, and the aft end of the tube is hydraulically connected to the launch tube. The elastomeric bladder is externally of generally cylindrical shape and has an open aft end, a closed forward end and a side wall of varying thickness. The open end of the bladder is hydraulically connected to valves which act to control charging of the bladder and firing of the bladder. The bladder expands to contact the wall of the bypass tube when the bladder is filled with pressurized seawater.
