Northrop Grumman to Supply Air Traffic Management Systems at UK Airports

LONDON, September 1, 2010 - Northrop Grumman Corporation's (NYSE: NOC) Europe-based air traffic
management systems subsidiary, Northrop Grumman Park Air Systems, has been
awarded contracts by NATS Services to provide surface movement radar and air
traffic monitor systems for Heathrow airport's virtual contingency facility
(VCF) and instrument landing systems (ILS) for regional airports around the
UK.

"These contracts consolidate the strong position we have in the UK air
traffic management market," said Eldar Hauge, managing director of Northrop
Grumman Park Air Systems in Norway. "Our surveillance technology and control
systems will enhance the operations by the VCF helping air traffic
controllers to monitor and control flights even when they are unable to see
aircraft departing, arriving or moving around the airfield, and our
state-of-the-art instrument landing system will ensure safe and precise
landings, even under the most difficult visibility conditions."

The VCF has been developed and put into service by NATS Services and is
the world's first full safety certified remote airport contingency control
room that can keep flights moving through Heathrow airport in the event of a
serious problem at the airport's main control tower. Northrop Grumman Park
Air Systems is providing the NOVA 9000 advanced-surface movement guidance and
control system (A-SMGCS) equipment and NOVA 9000 air traffic monitors.

The VCF, housed in a facility away from the airfield, is a remote air
traffic control tower located near London Heathrow airport and enables the
airport to operate at 70% of its capacity in the event of an emergency
involving the main control tower. The VCF is designed with exactly the same
equipment and control positions as the main control tower. The two
independent systems monitor and present the traffic situation to the Heathrow
controllers within an area of 20 nautical miles and to and from the gates.
Both systems have in-built automation and safety logic functions.

Northrop Grumman Park Air Systems will also supply NATS Services with the
NORMARC 7000B ILS CAT III for Newcastle, Luton and Leeds Bradford airports.
These contracts follow on from previous contracts awarded for the supply of
air traffic management systems on the Isle of Man and Jersey. The NORMARC
7000B is the world's leading ILS system, using state-of-the-art technology to
ensure safe and precise landings, even under the most difficult visibility
conditions.
