Abstract
In an electromagnetic rail gun launcher that includes a set of spaced-apart rails defining an inside bore for slidably receiving an armature-type projectile, with the rail gun and armature configured such that when powered up the projectile is forced from a breech of the rail gun toward a muzzle of the rail gun to then launch the projectile, the improvement wherein a lubricant reconditioning pad, containing a lubricant, is secured to the projectile in a location such that it contacts the rails. As the projectile moves through the bore, the pad cleans debris from, and applies lubricant to, the rails to thereby lubricate and recondition the rails during each shot.
