Lockheed Martin says ER GMLRS passed operational tests and is moving to production and fielding with a range of up to 150 km

Lockheed Martin said on 19 October 2026 that the Extended-Range Guided Multiple Launch Rocket System (ER GMLRS) is moving toward production and fielding after two Soldier-led operational tests, with the US Army approving Milestone C.

The company gives the rocket’s range as up to 150 kilometres, and says it stays compatible with the HIMARS and M270 launchers. Both the Alternative Warhead and Unitary Warhead variants completed operational testing, after flights in September and October. According to the release, several rockets were fired in succession from an M270A2 launcher at White Sands Missile Range in New Mexico.

Milestone C is the US defence acquisition decision that clears a programme to enter production and deployment.

A wider precision-fires family

Lockheed Martin presents ER GMLRS as part of a family that also includes the standard GMLRS, ATACMS and the Precision Strike Missile, which share elements of a common launcher ecosystem. The company says it is expanding production capacity across that portfolio, but the release gives no production numbers, contract values or delivery quantities. It refers to the US Army and allied nations as users, without naming any customer.

“The value of ER GMLRS is not only the additional range,” said Sabrina Barnes, vice president of Lockheed Martin Precision Fires Rockets.

Supply chain background

The announcement follows two supply-side deals this month. Geopolitiki reported Lockheed Martin and Avio sign deal on solid rocket motors for ER GMLRS and PrSM missiles and L3Harris wins $250 million from Lockheed Martin for record GMLRS rocket motor order.
