Abstract

An improved inertial projectile arrangement including a subcaliber projectile penetrator which is composed of a prepenetrator portion with a nose point and a main penetrator portion. The penetrator has a large length/diameter ratio and a high density. A sabot, composed of at least two segments, encompasses a part of the prepenetrator portion. The periphery of the encompassed prepenetrator and the sabot being joined to each other by form-locking means. The sabot segments separate from the penetrator upon exiting from the muzzle of the gun barrel from which the projectile is fired. The form-locking means are at least partially formed of irregularities or unevenesses on the periphery of the encompassed prepenetrator portion and the interior periphery of the sabot. A plurality of fracture zones and a transfer frusto-conical portion are disposed on the prepenetrator. The fracture zones achieve an intended breakup of the prepenetrator upon impact. A predetermined number of the fracture zones form part of the form-locking means. The frusto-conical transfer portion adjoins the fracture zone most distant from the nose point of the prepenetrator at one of its ends and the main penetrator portion at the other of its ends.
