An apparatus for pressurizing a submarine launch tube in order to launch a device therefrom includes a weighted first piston received in a vertically disposed first cylinder member, a second piston received in a second cylinder member, a connecting rod mechanically connecting the first and second pistons and a conduit connecting the second cylinder member to a launch tube. The first piston member is constructed such that downward gravitational movement thereof in the first cylinder member is operative for moving the second piston member in the second cylinder member in order to force water received in the second cylinder member outwardly under pressure through the conduit and into the launch tube.
