Northrop Grumman to Provide Flight-line Security Systems for Royal Australian Air Force C-17 Aircraft

CANBERRA, Australia, March 1, 2011 - The Australian Defence Materiel Organisation has awarded Northrop Grumman
Corporation (NYSE: NOC) a contract to provide integrated airfield and asset
protection solutions for the Royal Australian Air Force C-17 aircraft.

Northrop Grumman will deliver its Expeditionary Tactical Automated
Security System (ExTASS) for the protection of the Australian C-17s while at
home air stations and during expeditionary operations.

ExTASS is an implementation of the Tactical Automated Security System
(TASS), deployed at more than 100 sites worldwide by the U.S. Air Force, U.S.
Army and U.S. Marine Corps. Like TASS, ExTASS is an open architecture,
command-and-control platform for the integration of a variety of sensors
designed for force-protection missions. The system provides for real-time
detection and assessment of intrusions, thus allowing immediate coordination
of appropriate response. The ExTASS will be configured in a mobile trailer
for quick deployment.

"This contract demonstrates the continued cooperation between the U.S.
and Australia in the worldwide fight against terrorism," said Michael Danick,
programs director with the integrated command, control, communications and
intelligence systems business of Northrop Grumman Information Systems sector.
"We are proud to expand on our critical infrastructure and force protection
capabilities to support the Australian Department of Defence."

Northrop Grumman is a leading provider of protection systems such as
ExTASS. The company is one of the prime contractors supporting the U.S. Army
Counter-Rocket, Artillery and Mortar (C-RAM) program office in other related
efforts such as the delivery of the C-RAM sense-and-warn capability to
protect U.S. and Australian forces in Afghanistan.

Northrop Grumman has well-established relationships with Australia and
other countries in the region, where it has been supporting a variety of both
defence and civil programs for more than 20 years. Northrop Grumman is a key
subcontractor for the Wedgetail AEW&C, F-35 Joint Strike Fighter and the
FA/18 Super Hornet programs.
