General Atomics Tests Long-Range Maneuvering Projectile

General Atomics Electromagnetic Systems has successfully tested its Long Range Maneuvering Projectile (LRMP), a guided artillery round designed to hit targets more than 100 kilometers (62 miles) away.

The LRMP is designed to bring missile-like accuracy to conventional artillery. Multiple rounds were fired from an M777 howitzer during recent trials at Yuma Proving Ground, which validated key functions such as wing deployment, de-spin stabilization, and guided flight.

According to the company, the tests confirm the round’s ability to achieve controlled trajectories and maintain accuracy at long range.

General Atomics President Scott Forney said the results demonstrate the maturity of the technology and support upcoming extended-range tests under US Navy and Army programs.

“As the US faces rising threats from near-peer adversaries and increasingly contested environments, affordable, mass-produced artillery is critical,” he said. “LRMP meets that need while proving its ability to perform in extreme conditions and reshape long-range firepower.”

Role of the Long Range Maneuvering Projectile

The LRMP is a guided, winged 155mm artillery round that can adjust its flight path after launch. The system is part of a broader US effort to extend the range and precision of conventional artillery without requiring new launch platforms. The US first commissioned development from General Atomics in December 2024.

Several defense contractors are pursuing comparable technologies. BAE Systems has been testing its Scorpio-XR precision artillery round, designed to reach similar ranges and integrate with US Army howitzers.

Meanwhile, American Rheinmetall Munitions is collaborating with the army’s Extended Range Cannon Artillery program to supply advanced propellant and ammunition systems that could pair with next-generation precision rounds.
