Abstract
An artillery piece which has a gun barrel made up of a parallel rail electromagnetic launcher bore. Current from a source is injected into the rails to propel a bridging armature and projectile. The velocity of the porjectile is measured as it traverses a certain position within the barrel and the measured velocity is compared with a predetermined desired velocity. The velocity of the projectile is modified (if required) toward the muzzle end of the rails as a result of the comparison.
