The United States Army has awarded Lockheed Martin a contract modification to insert Gallium Nitride (GaN) into the AN/TPQ-53 (Q-53) radar as part of the full rate production configuration to increase the range of the radar.

The Q-53 radar in the US Army inventory and has the flexible architecture to address aircraft, drone and other threats in the future. The transition to GaN will provide the Q-53 with additional power for capabilities including long-range counterfire target acquisition.  GaN has the added benefit of increasing system reliability and reducing lifecycle ownership costs, the company said in a statement Monday.

The primary mission of the multi-mission Q-53 is to protect troops in combat by detecting, classifying, tracking and identifying the location of enemy indirect fire in either 360 or 90-degree modes. Mounted on a five-ton truck, the Q-53 can be rapidly deployed, automatically leveled then operated remotely or from a command vehicle with a laptop computer. The radar is software defined allowing for quick adjustment to address emerging Army capability needs for air surveillance and counter fire target acquisition.
