For use with 115mm tank guns to defeat armored targets by means of the kinetic energy (KE) of its tungsten alloy long rod penetrator. The projectile consists of a sub-projectile and sabot. The sub-projectile is comprised of an Armour-Piercing Fin Stabilized tungsten alloy long rod penetrator, an aluminum windshield, and a tracer assembled in the fin assembly. This is contained within a 3-piece aluminum Discarding Sabot, held in place with a plastic band at the forward end and a plastic obturating band at the rear end of the sabot. The projectile is crimped to the cartridge case which is loaded with cool burning, multi-perforated, loose propellant and is fitted with a percussion primer and a wear-reducing liner.
