LINTHICUM, Md., Feb. 7, 2011 -- Northrop Grumman Corporation (NYSE:NOC) today announced the integration of all subsystems of the AN/TPS-80 Ground / Air Task Oriented Radar (G/ATOR) system.

This first, complete G/ATOR system is currently undergoing system-level integration and performance testing to include live target testing at the company's Electronic Systems sector engineering and manufacturing complex adjacent to the Baltimore Washington International Marshall Airport.

G/ATOR's subsystems include the Radar Equipment Group (REG), the Communications Equipment Group (CEG) and the Power Equipment Group (PEG). The heart of the AN/TPS-80 G/ATOR system, the REG consists of the advanced Active Electronically Scanned Array (AESA) antenna and all associated control and processing electronics mounted on a lightweight tactical trailer.

The REG, CEG and PEG have all undergone subsystem integration and testing. Live target testing, which is currently taking place, will provide an added measure of confidence that G/ATOR performs as required against a wide array of target types and sizes, speeds, ranges and trajectories.

"This is a major milestone for the Northrop Grumman and U. S. Marine Corps G/ATOR team as we are growing ever closer to delivering unprecedented mission functionality to our nation's warfighters," said John Jadik, vice president, weapons and sensors for Northrop Grumman's Land and Self Protection Systems Division. "In addition to serving the Marine Corps, G/ATOR's multi mission capabilities, including simultaneous multi mission performance, are well suited to meet future Air Force and Army ground radar mission requirements as well.

"In keeping with current Office of the Secretary of Defense guidelines for achieving significant program efficiencies, the Marine Corps' investment in G/ATOR offers substantial near-term and long-term cost savings to the Army and Air Force and allows both services to substantially accelerate deployment of enhanced threat detection and tracking capabilities to their operational troops," Jadik added.

G/ATOR will replace five legacy single mission Marine Corps ground radars, providing the warfighter with much earlier and more reliable detection, tracking and engagement of a broad array of airborne threats, helping to enhance the safety of Marines worldwide.  G/ATOR's predicted reliability is also several times greater than that of the current Marine Corps ground radars.

The G/ATOR contract was competitively awarded to Northrop Grumman in early 2007 by the Marine Corps System Command and the program is managed by the Marine Corps Program Executive Office for Land Systems in Quantico, Va.
