Northrop Grumman to Upgrade Landing Systems in Africa

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
multi-million dollar contract by the African air navigation safety agency
Agence pour la Securite de la Navigation Aerienne en Afrique et a Madagascar
(ASECNA) for a continent-wide upgrade and renewal of their instrument landing
systems.

Northrop Grumman Park Air Systems proposed their Normarc 7000B instrument
landing system (ILS) in an international tender in which all players in the
industry participated. ASECNA is a world-leading agency for air navigation
security and selected the Normarc 7000B ILS for its unparalleled performance
and reliability. The agency has a large number of Normarc 7000 ILS already in
service throughout the continent.

The ILS will be installed and commissioned by French partner company GTIE
Air & Defense of the Vinci Group on a turnkey basis. The systems will be
installed and commissioned over a five-year period at 13 different airports
and sites in Africa.

"We look forward to continuing our working relationship with ASECNA and
to upgrading the instrument landing systems across Africa," said Eldar Hauge,
managing director of Northrop Grumman Park Air Systems in Norway.

The Normarc 7000B ILS is the latest generation of the company's highly
successful ILS products. The Normarc 7000 ILS was developed in 1995 and has
since gone through several updates and upgrades to become the most reliable
and precise ILS on the market.
