The LSAT light machine gun is a component of the Lightweight Small Arms Technologies (LSAT) program. The purpose of the program was to develop a lighter, yet highly reliable light machine gun (LMG). The program was initiated in 2004, when the Joint Service Small Arms Program (JSSAP) challenged the American defence industry to develop a lighter small arms and also design lighter ammunition.
The LMG provides a major reduction in weight over legacy weapons, as well as improvements in other areas, such as controllability and reliability. As of 2008, it had two configurations, one that fires cased telescoped ammunition, and one that fires caseless ammunition. After further research and development into both technologies and the guns that fire them, one of the two variants was to be chosen for production. By May 2015, 85,000 cased-telescoped rounds had been fired through 10 test weapons, with testers claiming the weapon had gone as far as it can go until the Army decides if it wants to make it a Program of Record.
