Northrop Grumman Launches Airport Collaborative Decision Making Capability

LONDON, February 4, 2011 - Northrop Grumman Corporation's (NYSE: NOC) Europe-based air traffic
management subsidiary, Northrop Grumman Park Air Systems, has launched
Airport Realtime Collaboration (ARC), a technology and services capability
for the implementation of collaborative decision making solutions in airport
operations.

ARC is designed to provide the airport community with more accurate and
timely information for enhanced decision making and improved coordination of
airport operations. The ARC technology uses existing infrastructure, such as
the NOVA 9000 Air Traffic Management (ATM) suite, to deliver a common
situational awareness picture through web-based geographical and tabular
views of the airfield operations. ARC's processes can be optimised to combine
industry best practices with local airport needs.

Northrop Grumman Park Air Systems has entered into a long-term strategic
agreement with Rockshore, a specialist provider of real time information
technology. Rockshore has deployed technology that is already in use in
multiple airports in Europe. Northrop Grumman Park Air Systems has
established a professional services team to support both the technology and
business process aspects of the introduction of ARC.

Airport collaborative decision making (A-CDM) is a concept developed by
the aviation community to improve the operational efficiency of airports by
reducing delays, improving the predictability of events during the progress
of a flight and optimising the utilisation of resources.

"The combination of technology and the support for business processes
provided by ARC enables a low-risk approach to the adoption of A-CDM. The
system can be implemented incrementally at a pace that is suitable for a
given airport and with minimum disruption to existing operations," said
Charles Houseago, managing director, Northrop Grumman Park Air Systems in the
U.K. "We have a long and successful history of delivering and supporting
complex systems in the aviation market across the world. This new capability
will put us in an industry-leading position in A-CDM and our agreement with
Rockshore allows us to offer proven technology to support this important new
venture."

The introduction of ARC builds upon Northrop Grumman Park Air System's
established expertise in managing aircraft traffic in complex airport
environments. The world leading NOVA 9000 ATM system with its flow management
and administrative tools provides airport operators with the ability to
manage large volumes of air traffic delivering improved safety, efficiency
and capacity. Together these systems result in enhanced surveillance and
reporting information.

ARC enables airlines, ground handlers, air navigation service providers
and airports to work together efficiently helping increase capacity, improve
safety and reduce environmental impact and costs. As an example, the amount
of time an aircraft is stationary with its engines running can be reduced and
runway capacity can be managed more efficiently.

With a 50-year legacy in air traffic management systems ranging from
individual airport installations to countrywide, multiple-site turnkey
integrated system solutions, Northrop Grumman's state-of-the-art air traffic
management systems are operationally controlling air traffic in numerous
countries around the world including recent major programmes in: France,
Norway, Brazil, Qatar, Oman, Canada, India, Poland, UAE, U.S. and the U.K.,
in both civil and military applications.

Northrop Grumman Park Air Systems based in Peterborough, U.K., and Oslo
and Horten, Norway, supplies communication, navigation and surveillance
systems for air-space operations worldwide.
