Northrop Grumman Highlights Unmanned Systems Capabilities at UV Europe 2010

LONDON, June 28, 2010 - Northrop Grumman Corporation (NYSE: NOC) is participating in the UV
Europe conference and exhibition where it will highlight its comprehensive
capabilities and experience in unmanned systems.

Northrop Grumman is an industry leader in the ISR domain and has been in
the unmanned systems business for more than 60 years, providing 100,000
unmanned systems to military customers in the U.S. and around the world. In
unmanned ground systems, the company has served the military, explosive
ordnance disposal and hazardous materials units and other first responders
for more than 25-years as a leading provider of mobile robotic systems for
applications in hazardous and potentially life-threatening environments.

UV Europe takes place 29-30 June 2010 at the Husa President Park Hotel,
Brussels, Belgium 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 at the
conference. Gene Fraser, sector vice president, Northrop Grumman Aerospace
Systems will give a presentation on unmanned aircraft systems in the maritime
irregular warfare environment including piracy, maritime patrol and
non-combat operations. Trevor Hughes, head of Engineering, Unmanned Ground
Vehicles for Northrop Grumman Information Systems sector in Europe will speak
on unmanned ground vehicles in the explosive ordnance disposal role.

"As unmanned aircraft systems technologies mature, modern armed forces
are realizing that the integration of autonomous systems into operational
networks can result in considerable savings while significantly improving
mission capability," said 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 announced this month that it has been awarded a US$517
million (pound Sterling 350.6 million) agreement to develop up to three Long
Endurance Multi-Intelligence Vehicle (LEMV) hybrid airship weapons systems
for the U.S. Army. These new systems will be capable of providing persistent
surveillance for more than three weeks at a time.

Northrop Grumman is providing the Euro Hawk(R) based on the Block 20
Global Hawk high-altitude, long-endurance (HALE) UAS. Euro Hawk(R) will serve
as the German Air Force's HALE SIGINT system and is the first international
configuration of the RQ-4 Global Hawk.

The company is also prime contractor for the NATO Alliance Ground
Surveillance (NATO AGS) system, currently in development at the company's
Melbourne, Fla. facility, in which the Block 40 RQ-4 version of the Global
Hawk unmanned aircraft UAV is a key component.
