Abstract: Disclosed herein is sabot for a sub-caliber projectile comprising a plurality of petals, such that a slip mechanism can be incorporated between the sabot petals and the pusher mechanism to decrease or prevent the sabot from rotating in a rifled gun bore, or the petals themselves can be separated into forward petals and aft petals, with only the aft petals rotating along with the gun rifle. When separate forward petals and aft petals are used, the torque transferred to the forward petals is greatly reduced, thus decreasing the angular rotation of the forward petals with the intent of preventing the forward petals from rotating. The slip mechanism has slip plates with low-coefficient of friction surfaces configured to contact adjacent slip plates prior to and during launch. As assembly, a system, and corresponding methods also are disclosed.
