Northrop Grumman, L-3 to Work Together in Bid for U.S. Navy's
EPX Aircraft

EL SEGUNDO, Calif., Dec. 17, 2007 (PRIME NEWSWIRE) -- Northrop Grumman
Corporation (NYSE:NOC) today submitted a proposal with L-3
Communications (NYSE:LLL) for the U.S. Navy's EPX aircraft program in a
world-class collaboration of industry leaders. The EPX platform will
provide a transformational, multi-intelligence capability delivering
strike targeting information to the warfighter.

The Navy envisions EPX as a shore-based, manned aircraft providing
intelligence, surveillance, reconnaissance and targeting (ISR&T)
support to carrier strike groups and theater, combatant and national
commanders. The EPX would assume the role of the Navy's EP-3E aircraft
and provide greatly expanded capabilities.

The proposal was submitted in response to a Navy broad agency
announcement (BAA) issued in November that solicited bids to develop an
EPX preferred system concept and analyze the risks and requirements.
L-3 will serve as the principal subcontractor to Northrop Grumman.

"Northrop Grumman and L-3 combine unmatched expertise in battle
management, airborne ISR&T and the development of special mission
aircraft," said Pat McMahon, vice president of Information Operations
and Electronic Attack for Northrop Grumman's Integrated Systems sector.
"We look forward to demonstrating our capabilities to meet the Navy's
critical need for an expanded ISR&T capability in a smaller, more
networked force."

Northrop Grumman has developed numerous mission systems solutions for a
variety of needs in ISR&T and battle management command and control. In
particular, Northrop Grumman brings decades of experience in naval
aviation systems integration with systems such as the E-2 Hawkeye and
EA-6B Prowler.

L-3 brings systems integration experience on a number of ISR&T
aircraft, particularly as prime contractor for the EP-3E, the proven
system the EPX will replace.

"L-3's success as a customer-focused ISR&T systems integrator is rooted
in our customer responsiveness and the ability to meet mission
requirements with technically innovative, platform-independent
solutions," said Mike Holmes, vice president of Federal Programs for
L-3's Integrated Systems subsidiary.

L-3 Integrated Systems is the industry's leading non-OEM aircraft
integrator, serving major ISR&T fleets for the U.S. and its allies for
more than 50 years. Major programs/fleets include the EP-3E, RC-135 and
EC-130, as well as programs for the United Kingdom, Australia, New
Zealand and the Republic of Korea.

In addition to their legacy with Navy systems, Northrop Grumman and L-3
Communications have extensive experience with U.S. Air Force and U.S.
Army systems, which will enable them to provide joint service
capabilities in their EPX solution.

Headquartered in New York City, L-3 Communications employs over 63,000
people worldwide and is a prime system contractor in aircraft
modernization and maintenance, C3ISR (Command, Control, Communications,
Intelligence, Surveillance and Reconnaissance) systems and government
