GMARS Rocket Launcher Tested by U.S.-German Defense Team

Defense Feeds – The GMARS Rocket Launcher, a next-generation Global Mobile Artillery Rocket System developed by Lockheed Martin and German defense leader Rheinmetall, has successfully completed its first live fire test.

Conducted at the White Sands Missile Range in New Mexico, this key demonstration showcased the GMARS Rocket Launcher’s ability to fire Guided Multiple Launch Rocket System (GMLRS) munitions—the same precision rockets currently deployed by the U.S. military and NATO allies. This achievement marks a significant advancement for modern long-range artillery capabilities designed for seamless NATO interoperability and enhanced strategic reach.

GMARS: A Game-Changing Precision Fires Platform for NATO Allies

GMARS emerges as a highly mobile, precise, and survivable artillery rocket launcher aimed at meeting the evolving demands of allied forces operating across diverse geographical theaters.

The system combines proven missile technology with innovative design, built upon the Rheinmetall HX wheeled vehicle platform.

This high-mobility chassis ensures compatibility with NATO’s standardized logistics infrastructure, promoting ease of maintenance and rapid deployment.

Unlike traditional tracked platforms, GMARS features a wheeled configuration that reduces logistical strain and supports better operational flexibility in challenging terrain and narrow European roads.

The live fire test confirmed the launcher’s capacity to deploy a variety of rockets and missiles, including up to twelve GMLRS standard or extended-range rockets, two Army Tactical Missile System (ATACMS) missiles, or four Precision Strike Missiles (PrSM).

This firepower is notably double that of the widely used HIMARS launcher, which operates with a single pod, positioning GMARS as a potent tactical asset for rapid, high-volume precision strike.

Furthermore, the system’s modular architecture enables it to integrate seamlessly with existing and future missile stocks used by NATO members, fostering multinational cooperation and simplified supply chains.

Paula Hartley, vice president and general manager of Tactical Missiles at Lockheed Martin, emphasized the company’s dedication to innovative defense solutions.

She described GMARS as a prime illustration of this commitment, underlining the readiness to push forward with system qualification and delivery to global partners.

Likewise, Dr. Björn Bernhard, CEO of Rheinmetall Vehicle Systems Europe, highlighted the system’s precision, reliability, and adaptability to the strategic needs of allied militaries.

Enhanced Long-Range Strike, Mobility and NATO Interoperability

GMARS is designed to address the critical capability gap between traditional tube artillery and air-delivered deep strike missiles by combining extended range, rapid redeployment, and precision targeting.

Offering interoperability with current missile platforms such as HIMARS and M270A2 MLRS, GMARS amplifies NATO’s tactical missile firepower with improved ammunition capacity and transportability.

The system’s integration of dual navigation systems—including GPS and inertial guidance—ensures accuracy even in GPS-denied or contested environments, a growing concern on modern battlefields.

Operationally, GMARS can support a wide array of missions, from disrupting enemy supply lines and command centers to suppressing air defenses and neutralizing time-critical targets.

Its wheeled chassis enables the launcher to “shoot and scoot” efficiently, minimizing its exposure and increasing battlefield survivability.

From a logistical viewpoint, GMARS meets road transport restrictions and is suitable for rapid movement along standard European transport routes.

Its under 40-ton weight and 700-kilometer range at speeds of up to 100 km/h enhance strategic mobility and reduce the need for extensive support infrastructure.

The program has already attracted interest from multiple NATO countries and partners, with a recent international summit gathering defense representatives from 14 nations to explore GMARS’s capabilities and future potential.

Plans are underway to integrate longer-range missile options, broadening the system’s reach beyond current capacities, and to equip it with next-generation targeting sensors.

Lockheed Martin and Rheinmetall’s joint development of GMARS reflects a broader effort to equip NATO and European allies with modular, scalable, and interoperable precision fires solutions in response to evolving battlefield challenges and heightened demand for rapid-deployment rocket artillery systems in Europe and beyond.

By capitalizing on the combat-proven components of existing launchers while innovating on mobility and firepower, GMARS positions itself as a future-proof, tactical artillery asset designed to enhance long-range strike capabilities across allied forces.
