About MUOS
Now a critical element of U.S. national security, military satellite communications delivers vital connectivity to armed forces around the globe, making warfighters safer and more effective.

The U.S. Navy’s Mobile User Objective System (MUOS) is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move. MUOS will provide military users more communications capability over existing systems, including simultaneous voice, video and data - similar to the capabilities experienced today with smart phones.

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. 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.

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

MUOS Team
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.

MILSATCOM Heritage
For MUOS, Lockheed Martin is building on its proven record of providing progressively advanced spacecraft for protected, narrowband and wideband military satellite communications. Lockheed Martin built the legacy Milstar protected communications satellites, as well as the Defense Satellite Communications Systems (DSCS) wideband communications spacecraft for the U.S. Air Force. Lockheed Martin is also the prime contractor on the U.S. Air Force’s Advanced Extremely High Frequency (AEHF) program, a next-generation military satellite communications system to deliver vastly improved global, survivable, highly secure, protected communications capabilities for strategic command and tactical warfighters operating on ground, sea and air platforms.

Arctic Reach

Arctic Reach: MUOS Satellite Experiments Show Polar CapabilityMUOS Activity in the arctic is growing as the polar sheet cap recedes. More people, shipping, exploration and search and rescue expose the need for secure communications to protect the region. However, getting satellite communications signal is extremely difficult. But not anymore.
