BAE Systems has successfully fired its Long-Range Precision Guidance Kit (LR-PGK) for 155mm artillery projectiles from the US Army’s Extended Range Cannon Artillery (ERCA) at Yuma Proving Ground, demonstrating airframe structural survivability under extreme firing conditions. The LR-PGK improves the accuracy of unguided artillery projectiles with low-cost navigation and guidance technology.
The guidance kit combines anti-jam GPS sensors with control planes that enable projectile maneuverability throughout flight, and is compatible with existing and future artillery projectiles. The ERCA survivability tests are a critical milestone for LR-PGK. The propellant blast, gun barrel pressure, and muzzle velocity truly tested the system’s resiliency.
“The LR-PGK has demonstrated its ability to help the US Army deliver accurate fires up to 70 kilometers and meet mission objectives with fewer shots,” said James McDonough, LR-PGK program director. “Adding precision guidance to standard munitions enables our customers to engage targets with greater efficiency and reduce collateral damage.”

. BAE Systems continues to advance the system design to improve capabilities, manufacturing readiness, and affordability. Following the tests, the company is focusing on long-range guidance, navigation, and projectile flight control. The kits must demonstrate their ability to operate at high spin rates, in challenging atmospheric conditions, and in the presence of enemy signal-jamming.
BAE Systems is a leader in artillery technology, precision guidance systems, and small form electronics. The company designs and manufactures the M109 family of Self-Propelled Howitzers and the M777 Lightweight Towed Howitzer, is a major supplier of artillery explosives and propellants, and has decades of experience developing and delivering precision guidance systems.
