MUOS-2 to be Placed in Storage Prior to 2013 Launch

SUNNYVALE, Calif., Jan. 16, 2013

SUNNYVALE, Calif., Jan. 16, 2013 /PRNewswire/ -- Lockheed Martin (NYSE: LMT)
has successfully completed required system testing on the second satellite in
the U.S. Navy's Mobile User Objective System (MUOS), designated MUOS-2. The
satellite has been placed in storage to await its scheduled launch date in
July 2013.

The MUOS constellation will provide significantly improved and secure
communications for mobile warfighters, including simultaneous voice, video and
data services – similar to the capabilities experienced today with smart
phones. The first MUOS satellite, launched February 24, and the associated
ground system are currently providing legacy on orbit capability, followed by
the launch of MUOS-2 in 2013. The five-satellite, global constellation is
expected to achieve full operational capability in 2015.

"The joint U.S. Navy and Lockheed Martin MUOS team completed an efficient
integration and test campaign of MUOS-2 and we look forward to delivering this
critical satellite for launch," said Iris Bombelyn, vice president for the
Lockheed Martin's Narrowband Communications mission area. "As we continue to
produce MUOS satellites, we expect to drive even greater efficiency and
affordability into our operations."

In the spring of 2013, Lockheed Martin will remove the satellite from storage,
perform final spacecraft component installations and conduct a final factory
confidence test in Sunnyvale, Calif., prior to shipping MUOS-2 to Cape
Canaveral Air Force Station, Fla., for its launch aboard an Atlas V rocket.

MUOS satellites are equipped with a Wideband Code Division Multiple Access
(WCDMA) payload that provides a 16-fold increase in transmission throughput
over the current Ultra High Frequency (UHF) satellite system. Lockheed Martin
announced completion and delivery of the waveform last week. Each MUOS
satellite also includes a legacy UHF payload that is fully compatible with the
current UHF Follow-on system and legacy terminals. This dual-payload design
ensures a smooth transition to the cutting-edge WCDMA technology while the UFO
system is phased out.

Lockheed Martin Space Systems, Sunnyvale, Calif., is the MUOS prime contractor
and system integrator. The Navy's Program Executive Office for Space Systems,
Chantilly, Va., and its Communications Satellite Program Office, San Diego,
Calif., are responsible for the MUOS program.

Headquartered in Bethesda, Md., Lockheed Martin is a global security and
aerospace company that employs about 120,000 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 2011 were $46.5 billion.
