US Space Force taps Boeing for US$2bn to expand secure military comms capability

These satellites are designed to prioritise reliable voice and essential data communications, ensuring military users can remain connected in challenging operational environments. The first satellite is expected to be delivered in 2031.

MUOS SLE aims to sustain and improve a critical communications capability used by military personnel operating on land, at sea and in the air, particularly in regions where secure and dependable connectivity can be difficult to maintain.

Boeing Space Mission Systems vice president Sam Greaves said the company is honoured to continue supporting the program: “We’re grateful for the trust the US Space Force has placed in our team for a capability that matters to military users around the world.”

“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 extend and improve a system they rely on every day,” Greaves said.

Boeing brings extensive experience in secure ultra high frequency (UHF) communications to the program and has played a central role in the existing MUOS constellation, including the development and delivery of satellite payloads.

UHF signals are valued for their ability to maintain communications in environments where other systems may struggle, including rugged terrain, dense urban areas and severe weather conditions.

The company’s approach to MUOS SLE focuses on increasing communications capacity, reducing interference and improving overall connectivity to support global operations well into the next decade. The system is based on Boeing’s 702MP medium-class spacecraft platform, designed to deliver high-capacity, high-performance communications for demanding military requirements.

Senior director of Space Communications Programs, Ryan Reid, said the contract reflected Boeing’s established track record in the sector: “This award builds on our deep UHF heritage and the trust we’ve built supporting this critical national security mission.”

“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 execution momentum, proven reliability, and schedule predictability to the US Space Force,” Reid said.

Boeing noted that it has recent production experience in the 702MP spacecraft class, having delivered multiple satellites since late 2025, providing additional confidence as the program moves into execution.
