A disk-shaped sabot is provided for accelerating a projectile body fired from a smoothbore barrel, the projectile body having the same caliber as the barrel. The sabot is configured so that it is supported only in sections on the rear zone of the projectile body to transmit gas pressure forces impacting the projectile body, at least one cavity remaining between the sabot and the rear of the projectile body. At least one pressure-relieving bore extends through the bottom of the sabot, through which bore propelling gases penetrate the cavity when the projectile unit is fired and produces a defined excess pressure in relation to the outer ambient pressure, which causes the sabot to separate from the projectile body as soon as the projectile unit, consisting of the projectile body and the sabot, passes the muzzle of the barrel and without impairing the further trajectory of the projectile body.
