Abstract: A gun launched projectile design which imparts forces to a subcaliber protile comprising: a subprojectile, a multi petal sabot, a pusher plate, and an obturator. The petals are of different length and have a scooped-out design on the face thereof, so as to induce a specific level of yaw to the projectile.

Abstract: A sabot comprised of a frangible material, having a substantially smooth er surface, and an inner surface which accommodates one or more penetrators. The sabot is capable of surviving gun launching and flight without disintegration. In one embodiment the sabot is comprised of a material which will disintegrate upon impact with a cardboard sheet having a thickness of 0.05" to 0.10" when travelling at a velocity between 4920 and 6890 feet per second. A preferred material is nylon 6/6. In another embodiment the sabot forms an aerodynamic shell about the penetrator or penetrators, allowing disks and other aerodynamically unstable penetrators to be launched.
