Northrop Grumman to Supply Largest Ever Air Traffic Control Radio Programme to China

LONDON, August 27, 2010 - Northrop Grumman Corporation's (NYSE: NOC) Europe-based air traffic
management system subsidiary, Northrop Grumman Park Air Systems, has been
awarded a contract by China Aviation Supplies International Tendering Co.
(CASITC) to supply VHF radio communication systems for the Chengdu area air
traffic control centre. In total, 110 channels will be operated from the
control centre which is currently under construction for the Air Traffic
Management Bureau (ATMB) of China. The programme represents the largest air
traffic control (ATC) VHF system delivered to date in China.

"This programme is the culmination of a 30-year relationship in supplying
dependable VHF air traffic control systems to China," said Charles Houseago,
managing director for Northrop Grumman Park Air Systems in the UK. "We look
forward to the successful completion of this project and a long continuing
relationship with the ATMB."

The 110 channels are distributed across 17 sites throughout the ATMB
South West administration region providing three services: Chengdu regional
control, airway radar control, and Europe and Asia airway control.

The multi-million dollar contract was won after a competitive tender
process, and follows the provision of several large systems to ATMB. The
system is centered on Northrop Grumman Park Air System's T6 range of VHF ATC
radios which have been extensively deployed throughout China over the last
decade.
