QUANTICO, Va., 26 Aug. 2015. Systems designers at Northrop Grumman Corp. are inserting new electronic technology into a new U.S. Marine Corps air-defense radar to make the system more effective in detecting rockets, artillery, mortars, cruise missiles, unmanned aerial vehicles (UAVs), and other low observables.

Officials of the Marine Corps Systems Command at Quantico Marine Base, Va., announced a $9.2 million contract modification Tuesday to the Northrop Grumman Electronic Systems segment in Linthicum Heights, Md., to insert gallium nitride components into the Ground/Air Task-Oriented Radar (G/ATOR).

G/ATOR is an expeditionary, three-dimensional, short-to-medium-range multi-role radar system designed to detect low-observable targets with low radar cross sections such as rockets, artillery, mortars, cruise missiles, and UAVs.
