A lightweight composite sabot useful in large, medium and small caliber rifled gun systems, wherein each of the sabot segments are reinforced with thin aluminum, or other, metal wedges to increase the torsional strength of the sabot body to survive the torsional forces created when fired from a rifled gun tube. And, which composite sabot also has a metal bulkhead about the periphery thereof, to reduce the spin and resulting hoop stresses, and to help protect the composite material during firing.

Composite sabot

A dual spin projectile includes a base; a body connected to the base with a first snap joint, the first snap joint allowing relative rotation between the base and the body; a can having an open forward end and connected to the body with a second snap joint, the second snap joint allowing relative rotation between the body and the can; an aft payload disposed in the body; a forward payload disposed in the can; and a cap connected to the can and closing the open forward end of the can.

Tracer visibility of APFSDS projectiles can be enhanced through a combination of increased steady state spin rate, reduced muzzle obscuration, and optimized airflow over the stabilizing fin geometry of the sub-projectile. The preferred means to increase steady state spin rates of the sub-projectile is to incline or deflect the fin blade tip portion, creating a larger, hotter burning, tracer plume.
