A pressurized light gas in a first chamber segment of a light gas gun is heated and highly pressurized by an electric discharge. Solid chemical propellant in a second chamber segment behind and separated from the first chamber segment by a perforated wall is ignited by the heated and highly pressurized light gas to form a gaseous piston to assist in accelerating the light gas against a projectile.
