Maneuvering and Striking Without GPS: US Tests New 155mm LRMP

General Atomics said it successfully tested its new Long Range Maneuvering Projectile (LRMP) at the U.S. Army’s Yuma Proving Ground.

In a series of launches in August, LRMP rounds were fired from an M777 howitzer using M231 propellant charges.

The tests verified key flight phases — pallet separation, spin stabilization, deployment of aerodynamic surfaces, and controlled descent.

Company officials say the results indicate the system is ready for further demonstrations at extended ranges.

The LRMP is a next-generation precision-guided munition intended to expand the reach and flexibility of 155 mm artillery systems.

Equipped with controllable aerodynamic surfaces and onboard navigation, the projectile can maneuver in flight and engage targets even if GPS is denied.

After firing, the round reaches an apogee of about 12–13.7 km. Its expected range is roughly 120-150 km.
