A subcaliber kinetic energy projectile (1) including a penetrator (2) and a segmented sabot (3) which is provided with a front support (4) and with a second support (5) that is disposed at an axial distance behind the first support, with the second support (5) including a rotationally symmetrical air pocket (6) that faces the first support (4) and the first support (4) is provided with air passage openings (43, 44, 45).In the sabot, the relationship of L/D.gtoreq.1.2 exists between the length L of the penetrator tip (8) ahead of the first support (4) and the caliber D. The relationship x.gtoreq.0.45 * .iota. further applies between the distances x and .iota., with x being the distance between the trailing edge (10) of the sabot and the base surface (11) of the air pocket (6) in the second support (5) and .iota. being the distance between the trailing edge (10) of the sabot (3) and the leading edge (12) of the sabot at the surface of the penetrator (2). Finally, the first support (4) is composed of at least three laterally extending web-like components (40-42) whose shape and dimensions are such that they form and have the effect of three separate air pockets.
