U.S Army Qualifies ER GMLRS Rocket In Key Range Test
The U.S Army has successfully tested its Extended Range Guided Multiple Launch Rocket System, or ER GMLRS, firing a 150 km-class rocket that doubles the strike range of the High Mobility Artillery Rocket System (HIMARS) family of launchers.
A qualification event held at White Sands Missile Range, New Mexico, on January 30 confirmed the capability of the ER GMLRS Alternative Warhead variant. The flight met Army performance metrics and verified integration with fielded launch platforms, including HIMARS and the tracked M270A2 Multiple Launch Rocket System.
Extended Range With Existing Systems
The ER GMLRS family builds on the Army’s long-standing Guided Multiple Launch Rocket System, which historically has had a roughly 70 km range. The ER variant increases that reach to 150 km, allowing units to engage targets at longer distances while preserving current launcher footprints and tactical procedures.
Army officials emphasized that extended range comes without the need for new vehicles or major changes in unit structure, a key factor for rapidly fielding capability across fires units.
Why This Matters
Doubling the range of a precision rocket provides commanders a deeper stand-off strike option while retaining accuracy. The Alternative Warhead variant tested offers an area effects capability that reduces unexploded ordnance risks, which can be especially important in coalition operations and permissive environments.
The ER GMLRS munition uses a GPS-aided inertial navigation system and enhanced propulsion and control mechanisms to achieve longer reach. It is compatible with both HIMARS and M270 launchers already in U.S Army inventories.
Platform Modernization
The M270A2 launcher used in the test represents the Army’s recapitalized variant of the tracked MLRS. It features upgraded fire control systems and improved mobility and crew protection. These enhancements help ensure seamless adoption of new munitions such as ER GMLRS and future precision strike munitions without retraining or retooling.
Next Steps
The Army plans follow-on operational tests of ER GMLRS before fielding it to units. Performance in these environments will help shape deployment timelines and doctrine updates ahead of broader issuance.
