HUNTSVILLE, Ala., Jan. 27, 2013 (GLOBE NEWSWIRE) -- Northrop Grumman Corporation's (NYSE:NOC)
command launch equipment (CLE) software effectively launched the ground-based interceptor in
today's flight test of the U.S. Missile Defense Agency's (MDA's) Ground-Based Midcourse Defense
(GMD) system.

"Our Northrop Grumman GMD team is committed to supporting MDA as they continue to enhance the
integrated missile defense capability needed to defend our nation, its allies and deployed
forces," said Kelley Zelickson, vice president of Air and Missile Defense Systems.

During the GMD flight test, known as CTV-01, a ground-based interceptor was launched from
Vandenberg Air Force Base, Calif., to test changes that have been made to the exoatmospheric kill
vehicle.

The CLE software controls the interceptor while on the ground, computes the detailed intercept
trajectory and provides it to the interceptor, and at the appropriate time commands the
interceptor's ignition and launch.

"The effectiveness of our fire control products were proven again in this latest test, continuing
our record of meeting all test objectives," said Steve Owens, GMD operating unit director for
Northrop Grumman and deputy program director for the Boeing/Northrop Grumman GMD team.

Northrop Grumman is responsible for designing and deploying the GMD fire control products, which
include the Fire Control System, In-Flight Interceptor Communications System Data Terminal,
Communications Network Equipment, Network System Manager and CLE software. Northrop Grumman is a
strategic partner, with The Boeing Company, of the GMD team.

Since 1998, Northrop Grumman's products have met the objectives for all 21 system flight and
ground tests. Northrop Grumman has also delivered and installed all 50 of its contracted products
on time every time and, since 2001, under budget.

Northrop Grumman personnel in Huntsville and Colorado Springs, Colo., develop the GMD products.
Harris Corp., a major teammate in Melbourne, Fla., provides hardware for the in-flight
communication system. Approximately 450 people are employed on this project at these three
locations and the deployment sites.

Northrop Grumman also supported the test through its prime contractor role at the Missile Defense
Integration and Operations Center in Colorado Springs. Company personnel provided engineering and
communications expertise that helped the Mission Control Center Facility and the NORTHCOM Command
and Control Battle Management and Communication system execute the mission. Northrop Grumman
engineers also continuously monitored all test executions to assess the progress and success of
the GMD flight test.
