Kinetic Energy Penetrator

Kinetic energy penetrator

A kinetic energy penetrator is a type of ammunition which, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target.

The term can apply to any type of armour-piercing shot but typically refers to a modern type of armour piercing weapon, the armour-piercing fin-stabilized discarding-sabot (APFSDS), a type of long-rod penetrator (LRP), and not to small arms bullets.

The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of mass and velocity, to force its way through armour. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that would develop, would destroy the target.
