Description
This cartridge is a high velocity, flat trajectory, discarding sabot round used in 105mm gun cannons against armored targets.
The projectile consists of a tungsten, nickel, copper penetrator seated in a steel base with tracer and aluminum forward sheath, These components are encased in an aluminum and magnesium sabot. A plastic centering band encircles the sabot at the forward end, fiber rotating band and rubber obturator are mounted toward the base of the sabot. The cartridge case contains a polyurethane laminar additive liner over the forward end of the propellant. The case is loosely packed with propellant, and is fitted with an electric primer.
The projectile is black with white markings.
Functioning
The primer is electrically initiated to ignite the propelling charge. Gases produced by the burning propellant propel the projectile from the gun and ignite the tracer which burns for a minimum of 2.5 seconds. The sabot discards upon leaving the gun tube by setback, centrifugal, and air pressure forces. The spin stabilized projectile sheathed core penetrates the target solely by kinetic energy.
