MGM-166 LOSAT

The MGM-166 LOSAT (Line-of-Sight Anti-Tank) was a United States anti-tank missile system developed in the 1990s by Lockheed Martin (originally Vought), to defeat tanks and other individual targets. Instead of using a high explosive anti-tank (HEAT) warhead like other anti-tank missiles, LOSAT employed a solid steel kinetic energy penetrator (KEM) to punch through armor. The LOSAT was fairly light, designed to be mounted on a Humvee light military vehicle, allowing the system to be air-portable. After testing in the 2000s, LOSAT development ended, but was the basis for later development of the smaller Compact Kinetic Energy Missile.
