Northrop Grumman to Deliver Air Traffic Control Communication Network for Nigeria

LONDON, September 17, 2010 - Northrop Grumman Corporation's (NYSE: NOC), Europe-based air traffic
management subsidiary, Northrop Grumman Park Air Systems, has been awarded a
USD1.6 million contract to supply and install the air traffic control radio
communications system for the Nigerian Airspace Management Agency (NAMA).
This will be the largest air traffic control radio system in Nigeria.

The contract was awarded by the prime contractor for NAMA, Deo Makro Ltd,
following an international competitive tender process. Northrop Grumman Park
Air Systems will provide more than 80 VHF radios of both high power (300W)
and standard power (50W) output for the flight information regional
communications network. This contract is part of NAMA's "Total VHF Coverage
of Nigeria" programme, aimed at providing effective air-ground communications
between pilots and Nigeria air traffic control centres.

"The supply and installation of Park Air VHF radios is designed to
seamlessly integrate with our existing and planned communications network and
Area Control Centre equipment to achieve total VHF coverage of Nigeria for
the use by NAMA," said Udoh Nnamdi Director of Safety Electronic Services at
NAMA.

The NAMA main control sites are at Lagos and Kano. The associated
en-route remote radio sites are: Sokoto, Maiduguri, Jos, Abuja, Ilorin, Port
Harcourt and Wukari. Wukari is a new site being established to help improve
the coverage of the south eastern delta region. Northrop Grumman Park Air
Systems has completed the initial stages of installation at the first site in
Lagos.

"We are pleased to be installing such a major network in Nigeria," said
Charles Houseago, managing director of Northrop Grumman Park Air Systems UK.
"Our radio technology is already used across Africa providing reliable
communications, and we look forward to expanding our service."

NAMA is responsible for significant ATC operations and controls most of
the European air traffic to and from central Africa, southern Africa and
South Africa. Northrop Grumman Park Air Systems has already supplied ATC
towers with T6 VHF communication facilities in Abuja, Kano, Port Harcourt and
Murtala Muhammed.
