A liquid propellant gun system has an annular differential piston journaled for telescopic movement with respect to an annular control valve and to the chamber of the firing bore; uses the piston, the valve and the projectile as valve means for controlling the injection of liquid propellant into the combustion chamber of the gun system; uses a displacement type control means to limit the rate of the loading of liquid propellant and to provide a positive evacuation of misfired liquid propellant from the combustion chambers; and incorporates a vernier control circuit to give direct control over the performance of the gun.

In a regenerative liquid propellant gun having a combustion space which includes that portion of the bore of the gun barrel behind the projectile before and during projectile acceleration during firing and wherein liquid propellant is injected through conduit means into the combustion space by means of force exerted on a body of liquid propellant in a dispensing reservoir by movement of a mechanical element responsive to the gaseous pressure in the combustion space during firing, the improvement wherein said conduit means comprises a passageway extending from said reservoir through the gun barrel to an opening into said bore at a location within the extent of that portion of the projectile to be fired which is in contact with the bore surface when said projectile is in its ready for firing position whereby the projectile acts as a valve to initially block flow of liquid propellant from said passageway into said bore and to subsequently permit such flow when the projectile moves down the barrel beyond said opening.
