The Compact Kinetic Energy Missile (CKEM) was a developmental program to produce a hypersonic anti-tank guided missile for the U.S. Army. Lockheed Martin was the primary contractor. The program was the third in a series of projects based on kinetic energy missiles that stretches back to 1981s Vought HVM through the 1990s LOSAT and finally to the CKEM. The Army Aviation and Missile Command (AMCOM) developed this program as part of the Army's Future Combat Systems. This missile was primarily an anti-tank weapon, and could be mounted on land vehicles and low-altitude aircraft. The goal of these weapons was to demonstrate a state-of-the-art system for the next-generation. The program has since been cancelled.
