MUOS-5 Satellite

A United Launch Alliance (ULA) Atlas V rocket successfully launched the MUOS-5 satellite for the U.S. Navy. The rocket lifted off from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida, June 24 at 10:30 a.m. EDT. MUOS-5 is the final satellite in the five-satellite constellation, which provides warfighters with significantly improved and assured communications worldwide.

«We are honored to deliver the final satellite in the Mobile User Objective System (MUOS) constellation for the U.S. Navy», said Laura Maginnis, ULA vice president, Custom Services. «Congratulations to our navy, air force and Lockheed Martin mission partners on yet another successful launch that provides our warfighters with enhanced communications capabilities to safely and effectively conduct their missions around the globe».

MUOS-5, like the four satellites in orbit, will carry two payloads in a single spacecraft. One will provide new Wideband Code Division Multiple Access (WCDMA) waveforms with greater capabilities, and one that supports the legacy Ultra High Frequency (UHF) communications systems in wide use among U.S. and international militaries and civil aviation.

In the new satellite, however, only the UHF system will be activated. The wideband function will provide the assurance of a spare in case anything happens to one of the other satellites.

In addition to the five satellites, the MUOS contract with an industry team led by Lockheed Martin also includes four large ground stations in Australia, Italy, Hawaii and the eastern U.S.; the WCDMA waveform; the receiving terminals; and the software to manage the systems.

The mission was ULA’s fifth launch in 2016 and 108th launch since the company formed in 2006. MUOS-5 was the seventh mission to be launched aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) 551 configuration vehicle, which includes a 5-meter diameter payload fairing and five solid rocket boosters. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.

«I am so proud of the team for all their hard work and commitment to 100 percent mission success», Maginnis said. «It is amazing to deliver our second national security payload from the Cape in just two weeks. I know this success is due to our amazing people who make the remarkable look routine».

ULA’s next launch is the Atlas V NROL-61 mission for the National Reconnaissance Office, scheduled for July 28 from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida.

The EELV program was established by the U.S. Air Force to provide assured access to space for Department of Defense and other government payloads. The commercially developed EELV program supports the full range of government mission requirements, while delivering on schedule and providing significant cost savings over the heritage launch systems.

With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered more than 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.
