General Atomics Advances Artillery Modernization with Successful LRMP Testing

The Long Range Maneuvering Projectile (LRMP) in flight, greater maneuverability and precision to defeat static or moving targets, with 2 to 3 times the range of current rounds.

General Atomics Electromagnetic Systems (GA-EMS) has successfully tested its Long Range Maneuvering Projectile (LRMP) at the U.S. Army’s Yuma Proving Ground, marking an important step forward in the modernization of long-range precision artillery. The recent flight trials achieved multiple milestones, confirming the projectile’s advanced performance and reliability when fired from an M777 howitzer.

During the August test, GA-EMS fired several LRMP rounds using standard M231 powder charges. The demonstrations validated critical functions including sabot separation, de-spin stabilization, wing deployment, and controlled descent — all key aspects that define the LRMP’s maneuverability and extended range capabilities.

The LRMP represents a new generation of smart, precision-guided munitions designed to dramatically increase the range and effectiveness of existing 155mm artillery systems. Outfitted with deployable aerodynamic control surfaces and onboard guidance technology, the projectile can dynamically maneuver during flight to accurately strike targets at long distances. Its design also enables operation in GPS-denied or degraded environments, offering a tactical edge in modern, contested battlespaces.

GA-EMS reported that data from the test flights closely aligned with predictive performance models. This successful validation provides a strong foundation for upcoming demonstrations, which will target engagements at significantly extended ranges.

“This milestone reflects our commitment to delivering disruptive technologies for precision artillery,” said Scott Forney, President of GA-EMS. “As the U.S. military faces increasing challenges from near-peer adversaries and highly contested environments, the need for affordable, precision-guided, and mass-producible artillery systems is greater than ever. The LRMP meets that need — proving its ability to perform in extreme conditions and helping to reshape the future of long-range firepower.”

The success of the LRMP test underscores GA-EMS’s growing leadership in advanced weapons development, particularly in the areas of electromagnetic systems, hypersonics, and precision-guided munitions. The platform supports U.S. Department of Defense modernization initiatives across multiple services, providing a scalable and adaptable solution for evolving battlefield requirements.

Beyond the LRMP, General Atomics Electromagnetic Systems continues to innovate across a wide range of domains — from undersea to space. The company’s portfolio includes electromagnetic launch and recovery systems, power generation and energy storage technologies, satellite systems, hypersonic platforms, missile defense systems, and laser weapons. These capabilities are developed to meet the demands of defense, government, and national security customers worldwide.

In addition to its defense programs, GA-EMS also applies its core technologies to commercial sectors including hazardous waste remediation, oil and gas, and nuclear energy. By combining decades of research, engineering, and manufacturing expertise, the company continues to deliver cutting-edge, mission-ready systems that strengthen U.S. technological and defense leadership.

The successful LRMP trials mark another milestone in GA-EMS’s ongoing effort to redefine what’s possible in long-range precision artillery, setting the stage for future demonstrations and deployment of this transformative capability.
