Northrop Grumman Highlights Network-Centric Communications Capabilities at the International Data Links Symposium, Vienna

LONDON, December 3 - Northrop Grumman Corporation (NYSE: NOC) is participating in the
International Data Links Symposium where it is highlighting its world-class
expertise in battlespace communications, network-centric command and control
and tactical data link (TDL) technology.

The International Data Links Society's Annual Symposium takes place in
Vienna at the Messezentrum Wien Exhibition & Congress Centre from 2-4
December. Northrop Grumman will be exhibiting at stand G5 in the Strauss 1
hall.

Tactical data links are essential components of integrated information
networks and provide the armed forces with the ability to exchange real-time
information to ensure close coordination of operations, from secure voice,
data and video to picture generation and weapon assignment. Northrop
Grumman's planning and management software is the industry standard for TDL.

Highlighted at this year's show is Northrop Grumman's internationally
exportable family of network-centric command and control systems including
the software applications Command and Control for the PC (C2PC) and
Interoperable C4I Services (ICS) as well as Agile Client and the Harbour
Coastal Security System (HCS).

Among the data link technologies on display are the Gateway Manager and
Multi-Link Service Gateway (MLSG) products. Gateway Manager is a powerful
data link router and forwarder that gives commanders the ability to network
multiple platforms communicating on different protocols while providing a
comprehensive operational picture in real time. Multi-Link Service Gateway is
a modular, scalable data link processor suitable for maritime, land, and
headquarters installations that provides standalone platform capability with
an upgrade path on new and existing platforms.

Also highlighted are Northrop Grumman's Common Link Integration
Processing (CLIP) software solution, Tactical Data Link Integration Exerciser
(TIGER) and Distributed Simulation and Stimulation System (DS3).

The CLIP software solution performs data transformation and processes
protocols for dissimilar communications formats allowing existing platforms
without a tactical data link, as well as platforms with different data links,
to communicate with each other.

TIGER performs data link testing for CLIP and JSS programmes by
stimulating systems under test with tactical scenarios, including Link 16,
Link 11, Link 22 and more. Analysts use the TIGER scenario developer
programme to script reusable scenarios for real-time testing.

DS3 provides high fidelity sensor simulation for a multitude of sensors,
including rotating radars, phased array radars, and identification,
friend-or-foe transponders. DS3's tactical environment simulator stimulates
combat systems with sensor, navigation and weapon system inputs.

The Joint Interface Control Officer (JICO) Support System, the next
generation of joint and coalition network-management systems, is also
available for viewing. This system provides net-centric services through a
transformational management system to enable IP-based networks of the future
to operate efficiently with current tactical networks.

In mainland Europe Northrop Grumman operates from locations in France,
Germany, Italy and Norway. In the UK, Northrop Grumman operates from primary
locations in London, Fareham, Chester, Coventry, New Malden, Peterborough,
