LONDON, July 20 --

Northrop Grumman Corporation (NYSE: NOC) will be participating in the UV Europe
conference and exhibition where it will highlight its industry leading
capabilities in unmanned aircraft systems and unmanned ground systems, and their
effectiveness in combating piracy and irregular warfare.

Northrop Grumman has a 60-year history of providing more than 100,000 unmanned
aircraft systems to military customers in the US and around the world.

UV Europe takes place 22-23 July 2009 at the Celtic Manor Hotel, Newport, Wales
and will address military and civil unmanned systems operating in all three
environments - air, land and sea.

Northrop Grumman representatives will be among the speakers on the first day of
the conference. Gene Fraser, vice president and deputy of the Strike and
Surveillance Systems Division for Northrop Grumman will present on unmanned
aircraft systems in the maritime irregular warfare environment including piracy,
maritime patrol and non-combat operations.

Trevor Hughes, senior engineering manager Unmanned Ground Vehicles (Remotec),
for Northrop Grumman Information Systems sector in Europe will speak on the
design and technology challenges of unmanned ground systems.

As unmanned aircraft systems technologies mature, modern armies are realizing
that the integration of autonomous systems into operational networks can result
in considerable savings while significantly improving mission capability, said
Gene Fraser. Unmanned aircraft offer vital persistent intelligence,
surveillance, target acquisition and reconnaissance capabilities for
peacekeeping and peace enforcement missions but also have an increasingly
important role in maritime patrol and non-combat operations.

Northrop Grumman will be exhibiting at UV Europe and will highlight its wide
range of unmanned aircraft systems. The Global Hawk high altitude long endurance
unmanned aircraft will be featured including the U.S. Navy Broad Area Maritime
Surveillance Unmanned Aircraft System (BAMS UAS), the German Luftwaffe Euro
Hawk(r) and the NATO Alliance Ground Surveillance unmanned airborne segment. The
MQ-8B Fire Scout vertical take-off and landing unmanned aircraft will also be
highlighted together with the X-47B Unmanned Combat Air System and the medium
altitude, extended range MQ-5B Hunter unmanned aircraft.

In addition, Northrop Grumman and AESIR Ltd, developers of a range of vertical
take-off and landing unmanned aircraft for urban and rural environments, will be
collaborating in a joint demonstration of unmanned ground and aircraft
capability for remote detection and disposal of explosive ordnance. Northrop
Grumman’s Wheelbarrow Mk8 Plus II unmanned ground vehicle adapted with the
removal of its standard arm will be used as a remotely-operated vertical
take-off and landing platform for AESIR’s Embler unmanned aircraft, a
development craft powered by an electric engine.
