Abstract
An electromagnetic projectile launcher having a pair of conductive rails with a breech and a muzzle end and an impedance electrically connected across the conductive rails adjacent the muzzle end of the conductive rails, and a second impedance in the muzzle end of the rails whereby arcs which commutate the current to the first impedance are confined within the muzzle to substantially suppress any external arc as the projectile exits from the launcher.
