Long-Range Precision Guidance Kit (LR-PGK) for 155mm artillery projectiles from the U.S. 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 U.S. 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.” #usarmy
