Abstract: A penetrator shell has at least a front and a rear high-density core element each having a front face and a rear and lying in a stack extending along an axis with the front face of the rear element engaging the rear face of the front element. The rear face of the front element and front face of the rear element are substantially complementary, part-spherical, and centered on the axis. Thus, the front element can rock or pivot on the rear element while remaining in contact with the front face thereof. A high-density main penetrator body is engaged against and extends axially rearward away from the rear face of the rear element. A casing sleeve is engaged snugly around the core elements and has a front end generally at the front element and a rear end secured to the main penetrator body. An aerodynamic tip is secured to and extends axially forward from the front end of the sleeve.

Abstract: An improved cartridge ammunition which includes an at least partially combustible shell casing and a projectile with a fin-stabilizing tail section mounted in a neck portion of the shell casing which thereby forms a first connection between the projectile and shell casing. A second connection between the projectile and shell casing is formed by means of a support element which is form-lockingly connected to both. The shell casing has a support region axially extending forwardly inside the shell casing from its bottom. The support element being mounted on said support region and being instrumental in assuring, due to its form-locking connections, that a predetermined axial force occurs in said support of element prior to disintegration thereof, between the tail section and the support region due to gas pressure build-up in the shell casing at firing of the ammunition.

Abstract: An improved subcaliber fin-stabilized penetrator projectile having a plurality of high density pre-penetrator elements mounted in axial alignment in front of a main penetrator body. A casing having a frusto-conically shaped inner axial through-bore is threadably mounted on said main penetrator body and said pre-penetrator elements are matingly mounted in said through-bore and have mating frusto-conical shapes. A ballistic hood is threadably mounted on the forward end of the casing. The main penetrator and pre-penetrator elements are made of a high density metal alloy.
