General Atomics Electromagnetic Systems (GA-EMS) has completed a flight test of its Long Range Maneuvering Projectile (LRMP) at the U.S. Army Yuma Proving Ground, validating several performance parameters for the next-generation 155mm artillery munition.
The August test involved multiple LRMP firings from an M777 howitzer using M231 propellant charges. The trials confirmed key capabilities, including sabot separation, de-spin stabilization, wing deployment and controlled descent.
According to GA-EMS, the LRMP is designed to increase both range and accuracy for existing 155mm artillery systems. The projectile features aerodynamic control surfaces and an onboard guidance system that allows it to maneuver mid-flight and engage targets in GPS-denied or degraded environments. Test results aligned with predictive simulations and produced data for future long-range demonstrations.
“This milestone reflects our commitment to delivering disruptive technologies for precision artillery,” said Scott Forney, president of GA-EMS. “As the U.S. faces rising threats from near-peer adversaries and increasingly contested environments, affordable, mass-produced artillery is critical. LRMP meets that need while proving its ability to perform in extreme conditions and reshape long-range firepower.”
GA-EMS stated that the LRMP project supports ongoing U.S. defense modernization initiatives and could be adapted across multiple branches. The company continues to develop technologies in electromagnetic systems, hypersonics and precision-guided munitions.
