The invention concerns a fin-stabilized discarding sabot projectile for employment from a rifled barrel and is particularly suitable for automatic cannons having calibers from 12.7 to 70 millimeters. The full rate of spin commensurate with the rifling twist of a specific barrel and the muzzle velocity is imparted to the projectile during launch using a rotating band which is fixed and an integral component of the discarding sabot. The discarding sabot design involves the in-place injection molding of the sabot body, including a seal with obturator, onto the fin-stabilized projectile. The absence of slipping rotating band provides for a rugged sabot configuration which is particularly important for ammunition employed from automatic cannons. Launching at full rate of spin results in large centrifugal forces acting on the components of the sabot which provides for instantaneous and precise sabot separation upon projectile exit from the muzzle. This combined with the highly repeatable and reliable tuning of the projectile spin rate permits excellent projectile accuracy and dispersion characteristics.
