SpaceX wins $2.29 billion Space Force contract for military data network

Key Points:

• The U.S. Space Force awarded SpaceX a $2.29 billion contract to develop the Space Data Network Backbone, a low Earth orbit satellite network designed to transport military data through space, enhancing global military communications.
• The network will use SpaceX’s Starshield satellites, a government-specific variant of Starlink, and will serve as the core backhaul layer for near-real-time data transmission among spacecraft, sensors, command systems, and weapons platforms.
• The SDN Backbone will integrate with the Space Development Agency’s Transport Layer constellation, forming a unified, open architecture to provide critical data transport for military operations.
• The contract requires delivery of a fully operational prototype by the end of 2027 and supports the Pentagon’s Golden Dome missile defense initiative by enabling rapid “sensor-to-shooter” connectivity for missile tracking and interception.
• The Space Force expects additional vendors to join the SDN architecture over time, and the program is backed by significant R&D and procurement funding in the fiscal year 2027 budget.
