Abstract
An electromagnetic rail gun launcher for launching an armature attached to a projectile includes a barrel, having a bore, and a body that includes a pair of main rails, a first pair of augmenting rails one of each lying outboard of and coextending with each of one of the main rails from the breech to the muzzle, a second pair of augmenting rails one of each lying outboard of and coextending with one of each of the first pair of augmenting rails, a first pair of electrically-conducting crossovers proximate to the breech and a second pair of electrically-conducting crossovers proximate to the muzzle and connected in series when the armature is positioned in the bore with power provided to the launcher. The exit speed of the projectile from the launcher is controlled by controlling the current to the launcher.
