In 2004, the Lightweight Small Arms Technologies (LSAT) program was initiated which licensed the G11 caseless ammunition. In Phase 1 lasting until January 2005, the HITP formula was reverse engineered and evaluated. In the 28-month-long Phase II, the G11 caseless ammunition was replicated and customized to U.S. Army preferences (higher burn rate). In May 2007, the caseless ammunition was scaled and adapted to the 5.56 mm projectile in a telescoped and round form. An alternative polymer cased version was created in parallel.
