Extending Secure Military Communications Worldwide
U.S. Space Force Awards MUOS Service Life Extension Contract To Boeing
The U.S. Space Force has awarded a Mobile User Objective System Service Life Extension (MUOS SLE) contract to Boeing valued at up to approximately $2.2 billion to sustain and enhance secure military communications for users around the globe. The award provides for two additional narrowband communications satellites, with the first spacecraft scheduled for delivery in 2031 to help maintain mission-critical voice and data links for forces on the ground, at sea, and in the air.
“For the people who depend on this connectivity, the need is clear: secure communication that works in demanding conditions.”

MUOS SLE is intended to extend the life of the existing MUOS constellation while increasing capacity and improving performance for military users who depend on secure connectivity in challenging environments. The system is designed to prioritize reliable voice and essential data services, acting as a narrowband communications lifeline when other links may be difficult to sustain.
Boeing brings decades of experience in secure Ultra High Frequency (UHF) communications to the MUOS program, having developed and delivered payloads for the current MUOS satellites. UHF signals are able to sustain connections in conditions where higher-frequency links can struggle, supporting operations in rugged terrain, dense urban areas, and severe weather.
The company’s approach for MUOS SLE is designed to increase communications capacity, reduce interference, and improve connectivity to support global operations well into the next decade. The new satellites will be built on Boeing’s 702MP medium-class spacecraft platform, which is intended to deliver high-capacity, high-performance communications tailored to narrowband military users.
“We’re grateful for the trust the U.S. Space Force has placed in our team for a capability that matters to military users around the world,” said Sam Greaves, vice president of Boeing Space Mission Systems. “For the people who depend on this connectivity, the need is clear: secure communication that works in demanding conditions. Our team knows this mission and is ready to help the customer extend and improve a system they count on every day.”
“This award builds on our deep UHF heritage and the trust we’ve built supporting this critical national security mission,” added Ryan Reid, senior director of Space Communications Programs at Boeing. “When military users are operating in the most demanding conditions, this narrowband capability is their lifeline. By building on our active 702MP spacecraft production line, we bring immediate execution momentum, proven reliability, and schedule predictability to the U.S. Space Force.”
Boeing reports it has delivered multiple 702MP satellites since late 2025, providing recent production experience that the company says will carry into MUOS SLE execution. The continued production cadence is expected to help support schedule and performance targets once the program moves into full development and manufacturing.
