Army asks SRCTec to build lightweight counter-mortar radar (LCMR) in $91.4 million order

ABERDEEN PROVING GROUND, Md. – U.S. Army air-defense experts are asking engineers at SRCTec LLC in Syracuse, N.Y., to build lightweight counter-mortar radar (LCMR) systems to help defend deployed warfighters from rocket, artillery, and mortar (RAM) attacks.

Officials of the Army Contracting Command at Aberdeen Proving Ground, Md., announced a three-year potential $91.4 million order to SRCTec on Thursday for LCMR systems, as well as vehicle mounts, spare parts, retrofit kits, and support services.

The LCMR family of counter-fire radars from SRCTec provides 360-degree surveillance and 3D rocket, artillery, and mortar location using a non-rotating, electronically steered antenna.

The SRCTec LCMR family consists of the AN/TPQ-49 and AN/TPQ-50. The TPQ-50 is the official Army program of record, while the TPQ-49 is designed for expeditionary forces, company officials say.

The radar systems detect and track several different rounds fired from separate locations, and send early warning messages indicating a round is incoming. The radar also pinpoints the location of the incoming round's launcher for counter-fire from friendly artillery, mortars, or aircraft.

Both systems are designed to cover 360 degrees over a nearly 200-square-mile area. The systems can be adapted to cover narrower sectors at longer ranges, if necessary.

The LCMR AN/TPQ-50 system detects incoming RAM from low-quadrant elevations, and provides a more accurate point of origin calculation from greater distances than its predecessors. The radar can be transported and operated on a vehicle such as a HMMWV, or rapidly emplaced in rugged terrain by installing it on a tripod.

The LCMR AN/TPQ-49 radar can be assembled or disassembled by two soldiers in 20 minutes. It mounts on a tripod using lightweight antenna hardware. The relatively small system consumes low prime power, making it suitable for low-profile operation.

On this contract modification SRCTec will do the work at locations determined with each order, and should be finished by July 2021.
