BALTIMORE, March 27, 2013 (GLOBE NEWSWIRE) -- Northrop Grumman Corporation's (NYSE:NOC) AN/TPS-80
Ground/Air Task Oriented Radar (G/ATOR) successfully detected multiple rocket launches during
company-funded testing.

Currently under development for the U.S. Marine Corps, G/ATOR is the first ground-based, multirole
radar to be developed for the U.S. Department of Defense. With its ability to intelligently and
adaptively allocate its myriad sensor capabilities, G/ATOR is able to detect and track a wide
variety of threats, including manned aircraft, cruise missiles and unmanned autonomous systems, as
well as mortar, rocket and artillery rounds.

The G/ATOR system successfully detected multiple rockets launched by NASA from its Wallops Island,
Va., test site, including three different rocket types. Data collected from the testing will be
used to verify potential future theater ballistic missile algorithms and ballistic missile defense
capabilities.

"Today's missile detection testing is yet another example of the expanded capability that is
possible with an Active Electronically Scanned Array (AESA) multimission radar," said Steve McCoy,
vice president of tactical sensor solutions at Northrop Grumman. "This demonstration required only
minimal software modifications to the G/ATOR system, and no hardware changes at all."

McCoy said other radar systems could also benefit from this capability. Potential applications for
the technology include the U.S. Air Force's Three Dimensional Expeditionary Long Range Radar, the
U.S. Army's Patriot Fire Control Radar, the replacement for the Marine Corps' aging TPS-59 radar,
and the U.S. Navy's Air and Missile Defense Radar.
