Northrop Grumman Provides Air Traffic Surveillance System for Thessaloniki Airport, Greece

LONDON, March 2, 2011 - Northrop Grumman Corporation's (NYSE: NOC) Europe-based air traffic
management subsidiary, Northrop Grumman Park Air Systems, is providing its
Advanced Surface Movement Guidance and Control System (A-SMGCS) for Greece's
Thessaloniki International Airport.

Under the contract awarded by Greek consultants ATESE following an
international competitive tender process, Northrop Grumman Park Air Systems
will deliver its NOVA 9000 A-SMGCS system for operation by the Hellenic Civil
Aviation Authority (HCAA). The company has previously supplied a similar
system for Athens International Airport.

"The NOVA 9000 A-SMGCS is widely accepted as a state-of-the-art system;
we know it well and have been operating it for many years at our main airport
in Athens. We and the controllers in Thessaloniki, look forward to its
commissioning before this 2011 winter season," said D6 director of Hellenic
Civil Aviation Authority.

The air traffic control system has successfully undergone system and
sensor testing in Norway, Denmark and Czech Republic. Northrop Grumman Park
Air Systems will deliver A-SMGCS to manage the tracking of aircraft and
vehicles on the ground and using surveillance systems based on radar and
multilateration, it will monitor aircraft at the airport's two crossing
runways. The system will assist the efficient management of air traffic
particularly in periods of high volume and during adverse weather conditions.

"We are pleased that our A-SMGCS capability has been recognised as the
system of choice by airport operators," said Eldar Hauge, managing director
for Northrop Grumman Park Air Systems in Norway. "This win maintains our
position as a leading supplier of A-SMGCS across Europe."
