Abstract:

A projectile that includes strakes mounted about the perimeter of the midsection of the projectile and a pusher plate assembly mounted about the aft of the projectile so that a sub-caliber projectile may be fired from a larger caliber gun. The pusher plate assembly forms a seal with the bore at the aft end of the projectile. The strakes maintain the center line position of the projectile within the bore. The pusher plate assembly further designed to fragment upon exiting the bore while the strakes remain with the projectile to enhance aerodynamic qualities of the projectile in flight.
