SUNNYVALE, Calif., April 8, 2014 /PRNewswire/ --The fourth Advanced Extremely
High Frequency (AEHF) satellite produced by Lockheed Martin [NYSE: LMT] is
taking shape after early deliveries of its payload and propulsion core.
AEHF-4, expected to launch in 2017, will enable the constellation to reach
full operational capability.

The propulsion core manufactured by Lockheed Martin and payload produced by
Northrop Grumman arrived at the AEHF integration facility in Sunnyvale,
Calif., earlier in the year. Both were delivered significantly ahead of
baseline schedule. The propulsion core arrived eight months early, and the
payload arrived two months early.

"We're driving a shorter timeline for bigger cost savings. In fact, we are
putting plans in place to finish six months ahead of our baseline schedule,"
said Mark Calassa, vice president of Protected Communication Systems at
Lockheed Martin. "AEHF's propulsion system reflects Lockheed Martin's
investment in more efficient spacecraft. To complement its traditional
chemical propulsion, AEHF uses the highest power electric propulsion system
ever flown for orbit raising and station keeping."

Lockheed Martin is under contract to deliver six AEHF satellites and the
mission control segment. Users are testing AEHF-1, AEHF-2 and AEHF-3 on orbit,
and the fourth satellite will enable the system to reach full operational
capability. The fifth and sixth satellites will add to the capacity of the
operational system and are being assembled at Lockheed Martin.

AEHF is the most secure communications satellite system used by the U.S.
government. Its jam-resistant communications are resilient against enemy
forces, including nuclear attack, and a single AEHF satellite provides greater
capacity than its compatible legacy five-satellite Milstar system. AEHF's
five-fold increase in data rates speed up protected communications, such as
real-time video, battlefield maps and targeting data. The constellation serves
troops and national leaders, including the president and Pentagon officials.

Headquartered in Bethesda, Md., Lockheed Martin is a global security and
aerospace company that employs approximately 115,000 people worldwide and is
principally engaged in the research, design, development, manufacture,
integration and sustainment of advanced technology systems, products and
services. The Corporation's net sales for 2013 were $45.4 billion.
