Dynamic Reference Unit Hybrid-Replacement (DRU-H-R)

By anticipating obsolescence—along with being responsive and flexible to accommodate end-user needs—L3Harris has captured the Paladin DRU-H-R program and continues to lead the way to “Common Artillery Accuracy” for today’s armed forces.

DRU-H-R is part of L3Harris’ combat-proven precision product family, delivering mission-critical information such as survey, pointing and position to our soldiers for precise, indirect mass fires and counter-fire operations. This unit replaces the DRU-H on Paladin, Firefinder and Long Range Air Surveillance Radar weapon systems, thus playing critical roles in supporting U.S. ground forces in all phases of active combat operations. The selected L3Harris design upgrades system performance by using high-accuracy combat-proven inertial sensors currently fielded on the Multiple Launch Rocket System (MLRS), High-Mobility Artillery Rocket System (HIMARS) weapons systems, and the IPADS survey system. The design upgrades, however, are not the only new benefit to this advanced precision delivery subsystem—the DRU-H-R has the growth capacity to add an embedded Selective Availability Anti-Spoofing Module (SAASM) GPS with M-code capability, as well as the ability to be configured to function in unmanned, rotational and shipboard environments.
