Northrop Grumman to build eight gallium nitride-based G/ATOR air-defense radar systems in $236.9 million deal

QUANTICO MARINE BASE, Va. – U.S. Marine Corps surveillance experts are ordering eight more versions of a radar system designed to protect Marines on attack beaches from 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 $236.9 million three-year order Friday to the Northrop Grumman Corp. Mission Systems segment in Linthicum, Md., for eight gallium nitride-based full-rate production versions of 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. Marine Corps leaders are developing and fielding G/ATOR in three blocks for use by the Marine Air Ground Task Force across the range of military operations, officials say.

The Northrop Grumman G/ATOR air-defense radar is designed to protect deployed Marine Corps warfighters on invasion beaches from rockets, artillery, mortars, cruise missiles, and UAVs. This procurement also includes spares parts and retrofit kits.

Northrop Grumman built G/ATOR for short-range air-defense (SHORAD) and tactical air operations Center (TAOC) air surveillance missions, including identification friend-or-foe (IFF). The increment I design was to provide for growth to all following increments without equipment re-design and provide an open architecture to enable upgrades with following increments.

The G/ATOR program was to showcase new component technologies, including the VPX embedded computing fast switch-fabric interconnect. As part of the G/ATOR program's first increment, Northrop Grumman has contracted with the Curtiss-Wright Corp. Defense Solutions segment in Ashburn, Va., for VPX-based embedded computers for radar signal processing.

The Ground Weapons Locating Radar (GWLR) portion of G/ATOR uses active electronically scanned array (AESA) radar technology to provide several different radar missions and adapt automatically to changing battlefield conditions.

On this order Northrop Grumman will do the work in Linthicum, Md., and should be finished by February 2024. For more information contact Northrop Grumman Mission Systems online www.northropgrumman.com.
