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 defence 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.
