SUNNYVALE, Calif., Jan. 8, 2013 /PRNewswire/ -- Lockheed Martin [NYSE: LMT]
has completed and delivered the software waveform for the U.S. Navy's Mobile
User Objective System (MUOS). The new waveform will enable military satellite
communications terminal providers to deploy equipment that takes full advantage
of enhanced MUOS capabilities.

A next-generation narrowband tactical satellite communications system, MUOS will
provide significantly improved and secure communications capabilities, including
simultaneous voice, video and data, for mobile and remote users.

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 tailored a previously commercial waveform to be used with the
new WCDMA payload. The U.S. government has made the waveform available for
military satellite communications terminal providers through the Joint Tactical
Networking Center (JTNC) Information Repository, and contractors can now
integrate the waveform into their MUOS-compatible terminals to provide WCDMA
capabilities for users.

"With the new WCDMA payload, MUOS is a game changer for the military worldwide,"
said Iris Bombelyn, vice president of Lockheed Martin's Narrowband
Communications mission area. "As our government and industry partners begin
deploying new communications terminals, remote and mobile tactical users will be
able to quickly and securely share video, data and voice communications critical
to their safety and mission success."

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 legacy system is phased out.

The first MUOS satellite and associated ground system already provide initial
on-orbit capability. After the second MUOS satellite is launched in July 2013
and completes on-orbit testing and check-out with the MUOS ground system and a
HMS Manpack terminal certified with the MUOS waveform, the system will provide
full WCDMA capability to users.

Lockheed Martin is currently under contract to deliver five MUOS satellites and
the associated ground system to the U.S. Navy. 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.
