Northrop Grumman to Provide Electronic Flight Strip System at Prague Ruzyne International Airport

LONDON, September 29, 2010 - Northrop Grumman Corporation's (NYSE: NOC) Norway-based air traffic
management subsidiary, Northrop Grumman Park Air Systems, has been awarded a
substantial contract by the Air Navigation Services of the Czech Republic
(ANS CR) to supply and install an electronic flight strip (EFS) system for
the control tower at Prague Ruzyne International Airport.

The EFS system automates the production, distribution and administrative
management of flight plan information and other air traffic control data and
replaces the paper strip systems previously used by air traffic controllers.
The EFS can also provide data integrity checking and ease the working
environment of air traffic controllers and paves the way for the application
of advanced features such as Controller Pilot Data Link Communications
(CPDLC).

"ANS CR is very pleased with the many years of cooperation with Park Air
Systems," said Jan Kubicek , ANS CR's programme manager for A-SMGCS. "Now we
look forward to putting the NOVA 9000 EFS system into operational use at our
airport."

Northrop Grumman Park Air Systems' offering to ANS CR is based on the
joint research carried out by the two organizations. This demonstrated that
fully integrating the advanced-surface movement guidance and control system
(A-SMGCS) with the EFS system, reduced controller work load and increased
efficiency and traffic throughput while maintaining the established safety
level.

"We have been a key supplier to ANS CR for many years. In addition to air
traffic control communication equipment we have also delivered surface
movement radar (SMR), advanced surface movement guidance and control systems
(A-SMGCS) and simulator equipment for Prague airport," said Eldar Hauge,
managing director of Northrop Grumman Park Air Systems in Norway. "We look
forward to continuing our close working relationship with ANS CR."
