Boeing to Build Narrowband Communications Satellites for U.S. Space Force

The U.S. Space Force has selected Boeing to advance the next phase of the Mobile User Objective System Service Life Extension (MUOS SLE) program. The contract award, valued at up to $2 billion, includes the production and delivery of two narrowband communications satellites configured to prioritize reliable voice and essential data networks. The first satellite under this agreement is scheduled for delivery in 2031.

Operational Framework and Environmental Resilience
The MUOS SLE program is structured to sustain and improve critical secure military communications capabilities for global forces operating across ground, maritime, and aerial domains. The infrastructure focuses on deploying assets to regions where reliable connections are traditionally difficult to maintain.

Boeing utilizes Ultra High Frequency (UHF) secure communications architecture for the program, leveraging its historical development and delivery of payloads for the active MUOS constellation. UHF signaling profiles are chosen for their technical capacity to maintain connectivity through harsh operational parameters, including obstructed terrain, dense urban environments, and severe weather conditions.

Spacecraft Architecture and Production Cadence
The system design adapts Boeing’s established 702MP medium-class spacecraft bus to meet high-capacity and high-performance communication constraints. The engineering approach aims to increase total communication throughput, mitigate external signal interference, and optimize connectivity to support global operations into the next decade.

By utilizing the active 702MP spacecraft production line, the project incorporates immediate manufacturing momentum, standardized reliability metrics, and schedule predictability. Supporting this production cadence, Boeing has manufactured and delivered multiple 702MP satellites since the fourth quarter of 2025, providing relevant assembly experience as the engineering teams transition into the execution phase of the MUOS SLE program.
