Description
This high velocity armor piercing cartridge is designed for use in 90mm guns against armored targets.
The projectile contains a hard armor piercing core of tungsten carbide steel in an aluminum alloy outer body. The outer body is fitted with two sintered iron rotating bands, a steel bourrelet, and an aluminum alloy windshield. The base of the body is skirted and contains a tracer. Modifications of the projectile are assembled with a sprayed base or steel base shield to counteract erosion. The cartridge case is loosely packed with propellant and is fitted with a percussion primer in the base.
The projectile is painted black with white markings.
Functioning
When the weapon is fired, the burning propellant creates gases which propel the projectile out of the gun tube and ignite the tracer which burns for a minimum of three seconds of projectile flight. Upon impact, the outer shell crumples and the tungsten carbide core penetrates the target solely by kinetic energy.
