OVERVIEW: 115mm Armor-Piercing Fin-Stabilized Discarding Sabot (APFSDS) rounds are high-velocity kinetic energy projectiles designed to defeat armored targets. These munitions were developed primarily for smoothbore gun systems and represent a major leap in anti-armor capability compared to traditional AP or HEAT rounds.

DETAILS: APFSDS ammunition utilizes a long-rod penetrator made from dense materials such as tungsten or depleted uranium. The projectile is housed in a sabot that discards after leaving the barrel, allowing the sub-caliber penetrator to travel at very high speeds. These rounds are primarily associated with the Soviet-designed 115mm U-5TS smoothbore gun, as used on the T-62 main battle tank. Their core purpose is defeating modern armored threats with minimal dispersion and high penetration at long ranges.

ROLE SUMMARY:
