A projectile intended to be fired from an electric rail gun having spaced current-carrying rails between which the projectile is accelerated when fired, includes an armature mounted on the projectile and arranged to make contact simultaneously with the rails to electrically connect the rails to one another. The armature is of annular configuration and rotates as the projectile is propelled through the electric rail gun.
