Description

This cartridge is an obsolescent armor piercing model currently used for training purposes in 90mm guns.

The projectile is a hardened steel monobloc slug and has no windshield. The projectile base is threaded to receive a tracer. The brass or steel cartridge case is loosely packed with propellant and is fitted with a percussion primer in the base.

The projectile is black with white markings.

Functioning

When the weapon is fired, the burning propellant ignites the tracer and creates gases. The gases propel the projectile out of the gun tube and ignite the tracer which burns for a minimum of three seconds of projectile flight. The projectile is designed to penetrate the target solely by kinetic energy.
