The Global Mobile Artillery Rocket System (GMARS), developed by Rheinmetall and Lockheed Martin, has successfully completed its first test firing in New Mexico, marking a significant milestone in the advancement of rocket artillery systems. The test took place at the White Sands Missile Range on August 7, 2025, demonstrating the GMARS’s capability to effectively fire rocket missiles.
The GMARS features a shoot-and-scoot capability, allowing it to launch its payload and relocate before enemy counter-artillery systems can respond. This technology has already proven its effectiveness in the ongoing conflict in Ukraine, where rapid mobility is critical to operational success. The introduction of GMARS could enhance the firepower available to both the United States and NATO forces.
Key Features and Capabilities of GMARS
During the testing phase, the GMARS showcased its precision and reliability. Dr. Björn Bernhard, CEO of Rheinmetall Vehicle Systems Europe, expressed confidence in the system, stating, “The successful live fire showcases the system’s precision and reliability, and we are confident that GMARS will meet the evolving needs of our customers.” Although the exact range achieved during the test was not disclosed, Rheinmetall has indicated that the GMARS is designed to support fire missions of up to 400 kilometers (approximately 250 miles).
This represents a substantial increase in range compared to the existing MGM-140 Army Tactical Missile Systems (ATACMS), which are already in effective use in various combat scenarios. The GMARS can potentially reach targets over 50 miles farther than ATACMS, positioning it as a formidable asset in modern warfare.
Integration with Existing Systems
The GMARS is designed to be compatible with munitions used by the M142 High Mobility Artillery Rocket System (HIMARS) and the M270 Multiple Launch Rocket System (MLRS). This compatibility is crucial for military operations, as it enables forces already trained on HIMARS systems to seamlessly integrate the new platform into their arsenal.
The GMARS can be equipped with two pods that accommodate different payloads, including up to 12 Guided Multiple Launch Rocket Systems (GMLRS), four Precision Strike Missile (PRSM) short-range ballistic missiles, or two MGM-140 ATACMS. This flexibility in payload options enhances the system’s versatility and operational readiness.
In summary, the successful testing of the GMARS represents a significant advancement in rocket artillery technology. As nations continue to adapt to the changing landscape of warfare, systems like GMARS offer a strategic edge, enhancing long-range fire capabilities while maintaining the necessary mobility to evade countermeasures. The swift development and testing of this system reflect the ongoing commitment of defense contractors like Rheinmetall and Lockheed Martin to provide innovative solutions for modern military challenges.
