Lockheed Martin-built MUOS-4 communications satellite ready for launch

The fourth Mobile User Objective System (MUOS) satellite built by Lockheed Martin (NYSE: LMT) for the US Navy was encapsulated in its protective launch vehicle fairing August 10. It is scheduled to launch August 31 aboard a United Launch Alliance Atlas V rocket.

MUOS-4 is the latest addition to a network of orbiting satellites and relay ground stations that is revolutionizing secure communications for mobile military forces. Users with operational MUOS terminals can seamlessly connect beyond line-of-sight around the globe and into the Global Information Grid. MUOS´ new smart phone-like capabilities include simultaneous, crystal-clear voice, video and mission data, over a high-speed Internet Protocol-based system.

MUOS, which also supports the legacy ultra high frequency communications satellite system, will provide comparatively 16 times the capacity of the legacy system and eventually replace it.

The MUOS-1, MUOS-2 and MUOS-3 satellites launched respectively in 2012, 2013 and January 2015. All four required MUOS ground stations are complete. MUOS-5, an on-orbit Wideband Code Division Multiple Access (WCDMA) spare with additional legacy system capability, is expected to launch in 2016.

Lockheed Martin manufactured MUOS-4 at the prime contractor´s Sunnyvale, California facility. Earlier this summer, the satellite shipped to the Cape, where it was pre-launch processed and finally encapsulated at Astrotech Space Operations, a wholly-owned subsidiary of Lockheed Martin.

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 112,000 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 2014 were USD45.6 billion.
