The U.S. Space Force has named SpaceX the recipient of a $2.29 billion contract to construct a secure, high-throughput satellite communications network intended to link military sensors and weapons platforms across the globe. The service characterized the award as a fixed-price nontraditional contracting agreement for the Space Data Network (SDN) Backbone.
According to the Space Force, the SDN Backbone is a proliferated low Earth orbit - pLEO - satellite constellation designed to expand a mesh of satellites that can deliver worldwide communications services with high capacity and low latency. The architecture is intended to be resilient and to provide data transport capabilities critical for defense missions.
The Space Force set a delivery milestone requiring the contractor to provide a fully operational prototype capability by the end of 2027. In describing the program, the service highlighted the SDN's role in operational data flows, including the movement of missile warning and tracking sensor data to interceptors in near real time - a capability identified as foundational to the Golden Dome missile defense initiative of the previous administration.
Commenting on the award, Space Force Colonel Ryan Frazier, the acting portfolio acquisition executive overseeing the program, said: "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."
The Pentagon stated the SDN Backbone will operate in concert with the Space Development Agency's Transport Layer to create a unified architecture capable of providing critical data transport for current and future Department of Defense missions. The Space Force also indicated it plans to identify additional contractors this summer for satellite construction and other elements of the network.
This award formalizes the government's selection of a commercial provider to architect a key portion of a distributed space-based data network, establishes a near-term prototype deadline, and links the SDN Backbone explicitly to missile defense data flows and the broader Transport Layer architecture.
