Abstract : Improved gun-firing system for electrically augmenting the energy released by ignited propellant of the system so as to increase the velocity of the projectile as it launches from the system thereby increasing the probability that it will strike a fast-moving target. The system is generally made up of a barrel and a breech. The breech is provided with a firing chamber for receiving a projectile and an ignitable propellant. In one embodiment, the breech of the system is generally comprised of a detonator, a pair of relatively spaced pressure-responsive switches and a helically wound electromagnetic coil A power supply is connected by an interlock to pull the switches and such that the coil is not energized until both switches close. These switches close in response to the pressure of the plasma that has been progressively formed from igniting the propellant in the breech chamber.
