Northrop Grumman to Upgrade Air Traffic Communication Infrastructure for Incheon Control Centre, South Korea

LONDON, August 27, 2010 - Northrop Grumman Corporation's (NYSE: NOC) Europe-based air traffic
management subsidiary, Northrop Grumman Park Air Systems, has been awarded a
contract by Korea's Public Procurement Service (PPS) to provide an air
traffic communication system that will deliver air-ground communication for
the Incheon air traffic control centre.

The contract was awarded following an international competitive tender
process. The new system will upgrade existing communications infrastructure
and will also include recording equipment, and a remote control and
monitoring system (RCMS), to allow centralised awareness of the equipment
performance and availability.

To provide the required coverage radio sub-systems will be located at six
sites across South Korea with centralised control and management based at
Incheon. The system architecture is based around Northrop Grumman Park Air
Systems' T6 range of VHF and UHF air traffic control radio equipment.

Northrop Grumman Park Air Systems is partnered with JoongAng Hitel, the
local contractor for installation services. This contract is the second phase
to replace old equipment.

"We are pleased to have been awarded this contract to upgrade the
existing infrastructure," said Charles Houseago, managing director of
Northrop Grumman Park Air Systems in the UK. "This award builds on our well
established presence in South Korea and we look forward to working again with
the Korean air traffic control authorities."

The contract is expected to be completed at the end of 2012 and follows
on from previous contracts awarded to Northrop Grumman Park Air Systems for
the supply of air traffic control systems across South Korea, including Gimpo
International Airport.
