Abstract

A cartridge for a kinetic energy projectile, where the projectile has a deter of less than a gun bore diameter and the projectile is saboted in order to support and guide the projectile along the gun bore. The sabot 42 has a closing disk 48 which radially extends from the projectile or penetrator 41 to the internal diameter of the gun bore. The closing disk is positioned on the penetrator at a location spaced from an open end 14 of a cartridge case 49. A shell 13 extends from the closing disk to the open end 14 of the cartridge case. The shell 13 is positioned adjacent the internal diameter of the gun bore, and the shell 13 along with the sabot defines a sabot volume. The sabot volume along with the volume defined by the cartridge case is filled with propellant.
