WASHINGTON, May ‌26 (Reuters) - The ​U.S. ​Space Force has awarded SpaceX a $2.29 billion contract to build a secure, high-speed satellite communications network ‌to connect military sensors and weapons platforms across ⁠the globe, the service announced on Tuesday.

The fixed-price nontraditional contracting agreement covers ‌the Space Data Network (SDN) ‌Backbone, a resilient network architecture providing high-capacity and low-latency data transport for the military.

Space Force said the vendor must ​deliver a fully operational prototype capability by the end of 2027.

Among other roles, the SDN will provide ⁠the communications pathways for integrating and moving data from missile warning and tracking sensors ​to interceptors in near real time — a capability seen as foundational to the Trump administration's ​Golden Dome missile defense initiative.

"The SDN ‌Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN ⁠mission set — a huge benefit and enabler for our warfighters," said Space Force Colonel Ryan Frazier, the acting portfolio acquisition executive ⁠overseeing the program.

The SDN Backbone is a proliferated low Earth orbit (pLEO) satellite ​constellation that will expand a mesh of satellites delivering worldwide communication services, the Pentagon said. It will work alongside the Space Development ‌Agency's Transport Layer to form a unified architecture providing critical data transport for current and ‌future Department of Defense missions.

The Space Force said it plans ⁠to identify additional contractors ‌for satellite construction and ​other network elements over the summer.
