The Armor Piercing Fin Stabilized Discarding Sabot (APFSDS) round or kinetic energy penetrator (also known as a KE weapon) is a type of ammunition which, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target.

This is a special kind of round that uses extremely high velocity to pierce armor or hard targets, such as a Jiralhanae.

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 armor. The modern KE weapon maximizes KE and minimizes the area over which it is delivered by:

  • Being fired with a very high muzzle velocity concentrating the force in a small impact area while still retaining a relatively large mass
  • Maximizing the mass of whatever (albeit small) volume is occupied by the projectile—that is, using the densest metals practical, which is one of the reasons depleted uranium is often used.
  • This has led to the current designs which resemble a long metal arrow.

APFSDS in Halo universeEdit

APFSDS rounds are most commonly known for appearing in Halo in the Sniper Rifle System 99 Anti-Matériel, Sniper Rifle System 99C-Series 2 Anti-Matériel, Sniper Rifle System 99C-Series 2 Anti-Matériel B and the Sniper Rifle System 99D-Series 2 Anti-Matériel. These weapons fire a 14.5x114mm cartridge at high velocity and leave a noticeable smoke trail. When used in skillful hands the APFSDS round can take out even a shielded enemy with one well placed shot, usually to the head.

TriviaEdit

  • Currently the term "APFSDS" is reserved for large Tank mounted weapons. In small arms such as the Halo sniper rifles it is called a Flechette.
