MUOS-4 Secure Communications Satellite Successfully Launched

The U.S. Navy’s fourth Mobile User Objective System (MUOS-4) satellite, built by Lockheed Martin, was successfully launched last week aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida.  The addition of MUOS-4 completes the initial constellation and provides the MUOS network with near-global coverage, extending the reach of communications further toward the North and South poles than ever before.

Lockheed Martin said 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. From its geosynchronous orbit, MUOS-4 will enable near-global coverage for a new secure military communications network offering enhanced capabilities for mobile 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.

The Navy's Program Executive Office for Space Systems and its Communications Satellite Program Office responsible for the MUOS program are based in San Diego.
