Northrop Grumman Demonstrates New Underwater Encapsulation Launch of
Non-Marinized Payloads

SUNNYVALE, Calif., Sept. 14, 2009 (GLOBE NEWSWIRE) -- Northrop Grumman
Corporation (NYSE:NOC) successfully demonstrated the underwater launch of a
"non-marinized" payload -- a payload not designed to be subjected to the
undersea environment -- by launching a Raytheon AIM-9X air-to-air test missile
shape from a submerged Tomahawk Capsule Launching System (CLS).

Conducted at the Army's Aberdeen Test Center in Aberdeen, Md., under the
Littoral Warfare Weapon (LWW) project, this test marks the first time an AIM-9X
test missile shape has been launched underwater. The launch demonstrates a new
degree of submarine self-defense capability against threats from coastal
surveillance aircraft, helicopters and high-speed small craft. LWW is a joint
teaming effort between PEO Submarines, Northrop Grumman and prime contractor of
the project, Raytheon.

"This test demonstrates that underwater launch payloads no longer need to be
designed and built to withstand the rigors of the undersea environment," said
David Perry, vice president of Northrop Grumman's Marine Systems business unit.
"By adapting the encapsulation technology Northrop Grumman pioneered for the
Tomahawk CLS, we have removed a significant barrier to launching many types of
airborne payloads."

Northrop Grumman's demonstrated encapsulation system opens the door to submarine
launch of a wide variety of defensive, offensive, communications, and ISR
(intelligence, surveillance and reconnaissance) payloads without needing to
adapt such payloads to survive in an undersea environment.

Northrop Grumman Corporation is a leading global security company whose 120,000
employees provide innovative systems, products, and solutions in aerospace,
electronics, information systems, shipbuilding and technical services to
government and commercial customers worldwide.
