US Army Clears 150 km ER GMLRS Rocket for Production After M270A2 Operational Tests

The US Army approved Milestone C for Lockheed Martin's Extended-Range Guided Multiple Launch Rocket System, authorizing the transition to production and fielding after soldier-led operational tests at White Sands Missile Range. The September and October 2026 trials fired both alternative-warhead and unitary-warhead rounds in succession from an M270A2 launcher. ER GMLRS is designed to reach up to 150 kilometers while retaining compatibility with HIMARS and M270 launchers. Lockheed Martin announced the production transition on October 19, although a first-unit fielding date and initial deployment quantity have not been disclosed.
