Northrop Grumman Highlights State-of-the-Art Maritime Systems at Euronaval 2010, Paris

LONDON, October 22, 2010 - Northrop Grumman Corporation (NYSE: NOC) will display a wide array of its
state-of-the-art ship and marine navigation, airborne mine countermeasures,
mission modularity systems and other capabilities and products at the
international naval defence exhibition, Euronaval 2010 in Paris.

Euronaval 2010 will be held at the Paris-Le-Bourget exhibition centre
from 25 to 29 October 2010 and includes the maritime sector and those
industrial activities associated with state actions at sea. The Northrop
Grumman exhibit is at location D-22, and an online media kit is available at
www.northropgrumman.com/euronaval/.

"The challenges faced at sea demand solutions that increase awareness of
the maritime domain," said Dave Perry, vice president and general manager of
Northrop Grumman's Naval & Marine Systems Division. "With our expertise in
design, development and production of navigation and control systems, radar
systems, airborne surveillance, and mine countermeasures, Northrop Grumman is
an industry leader at using innovative technology to counter increasingly
sophisticated sea-based threats."

Highlighted will be Northrop Grumman Sperry Marine's latest generation of
navigation, ship control and radar technology.

The company's VisionMaster FT and warship electronic chart display and
information system (ECDIS) will be on display configured to demonstrate how
the system is able to provide effective operational support required for
watchkeeping and command teams on smaller vessels. VisionMaster FT provides a
highly integrated fully networked suite of marine radar and electronic
charting systems designed to form the backbone of the modern ship's
integrated bridge.

Other capabilities which will be highlighted are the maritime domain
awareness (MDA) coastal surveillance system and the new SeaGuard XBCR x-band
coherent radar for small target detection and situational awareness.

Navigation systems on show will include Northrop Grumman Sperry Marine's
new MK39 Mod 4 ring laser gyro (RLG) inertial navigation system for naval
vessels. The MK 39 Mod 4 RLG provides the same high accuracy geographic
position information, with or without GPS, and precise attitude heading data
of its predecessors but in a smaller, more cost effective unit.

Northrop Grumman's world leading capabilities in airborne early warning
and control (AEW&C) will also be featured including the E-2D Advanced
Hawkeye. The E-2D Advanced Hawkeye programme has enhanced the E-2 mission
system with new more powerful avionics providing continuous 360-degree
scanning capability to detect, track and defeat cruise missile threats at
extended range.

Northrop Grumman's airborne surveillance capability will be highlighted
with a model of the MQ-8B Fire Scout, the vertical unmanned aircraft system
(VUAS) multi-role UAV currently under development with the US Navy for
littoral intelligence, surveillance and reconnaissance missions.

Northrop Grumman's airborne mine countermeasures programmes will be
highlighted with a display of the AN/AES-1 airborne laser mine detection
system (ALMDS).

The Northrop Grumman ALMDS, in low rate initial production for the US
Navy, is an airborne mine countermeasures, wide area surveillance system,
designed to detect, classify and localize floating and near-surface moored
sea mines. ALMDS uses its pulsed laser light and streak-tube receivers, day
or night to image in 3-D, the entire near-surface of the ocean. The system is
housed in a pod that is mounted on the port side of an MH-60S helicopter.
ALMDS is a key component of the Littoral Combat Ship (LCS) Mine
Countermeasures (MCM) Mission Package. Northrop Grumman is the LCS Mission
Package Integrator for the US Navy.

Related to that, Northrop Grumman will be discussing mission modularity
concepts, some of which are derived from the US Navy LCS Mission Package
concept for potential application for other navies. A model of the MCM
Mission Module will be on display.

The Modularity Concept and derived Mission Packages offer a truly
transformational option for naval forces that require the flexibility
provided by a modular system. Mission Packages and Mission Modules can be
adapted to meet specific mission needs. NATO is currently examining mission
modularity architecture for the design, installation and operation of modular
mission equipment packages for humanitarian and disaster relief, anti-piracy
and harbour defence missions.

Northrop Grumman has offices across Europe including: Freiburg and
Hamburg, Germany; Pomezia, Italy; Paris, France; Brussels, Belgium; Oslo,
Norway; and at locations across the UK.
