Abstract

An ammunition round for simultaneously launching multiple penetrators enclosed with a single composite sabot, without any nesting or physical contact between the penetrators. The composite sabot has petals which are engraved by the tube's rifling during launch to rotate the petals, without presence of a separate rotating band element. The petals are separated from the penetrator elements upon exit from the gun tube solely by centrifugal forces acting on the petals.
