Abstract

A sabot projectile with a subcaliber penetrator and a sabot, which has a propulsion element that acts on the rear end of the penetrator, a segmented, essentially cylindrical guide cage, which is connected to the front end of the propulsion element, and a segmented, disk-shaped metal guide element that extends radially inward in the front area of the guide cage and holds the penetrator. The disk-shaped guide element has a slightly convex contour in the direction of flight of the projectile and the material and the wall thickness of the guide element are chosen in such a way that convex area of the guide element is pushed back slightly when the sabot projectile is fired, so that the outer marginal area of the guide element rests against the inside wall of the gun barrel from which the sabot projectile is fired, and/or the inner marginal area of the guide element, which faces the penetrator, rests against the outer surface of the penetrator.
