The U.S. Army is enhancing its mobile ground-based radars designed to detect incoming enemy artillery rounds. The AN/TPQ-37 Firefinder weapon-locating radar is a long-range system that is being deployed across the service to locate the sources of enemy mortar, artillery and rocket fire, and to relay that data for counterfire by friendly units. As part of the Army's Reliability Maintainability Improvement (RMI) program, the entire inventory of AN/TPQ-37 and AN/TPQ-36 Firefinder systems will be modified with a modular, air-cooled transmitter and new common radar processors. ThalesRaytheonSystems officials, the company that is contracted for the modifications, note that the upgrades will significantly reduce life-cycle costs, provide higher operational availability and extend the radar's expected operational life to the year 2030. The modifications are part of a $285 million production contract.
