LSAT light machine gun
American weapons program
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.
History
Development began with the two types of weight-reducing ammunition, and a light machine gun to serve as a testbed and technology demonstrator. Use of an LMG for this purpose is notable, considering its greater technical complexity than infantry rifles. The use of advanced computer simulations to accelerate development may have mitigated this.

Why this record matters
“LSAT light machine gun” is worth following because a concise public description often conceals a longer documentary argument. Here, LSAT, light and machine provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q6459909. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2004, 2008 and 2015.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
