Also known as: HEAT

Quick Summary

High-explosive antitank (HEAT) ammunition is a type of shell designed to defeat enemy tanks. Developed in the 1950s, HEAT shells utilize a shaped charge with a conical cavity. This design concentrates the explosive energy into a high-velocity jet capable of piercing thick armor.1

While effective, HEAT rounds have been increasingly superseded by armor-piercing, fin-stabilized, discarding-sabot (APFSDS) ammunition since the 1970s. APFSDS projectiles feature long-rod penetrator cores and can be fired at velocities exceeding 1,650 meters per second, allowing them to perforate significantly thicker armor than earlier ammunition types.1
