The U.S. Space Force awarded SpaceX a $2.29 billion contract to build a military satellite communications network intended to provide faster, more resilient data transport from space.
The contract calls for a new network of low-Earth-orbit satellites that will work together to move large amounts of data among military units, sensors, and command centers worldwide.
According to Space Systems Command, the system is intended to provide fast, reliable communications during conflict. The Space Data Network Backbone program aims to expand the Space Force’s ability to move tactical and broadband communications through an optically interconnected satellite mesh.
The agreement requires SpaceX to deliver a fully operational prototype by the end of 2027 under an Other Transaction Authority agreement.
Col. Ryan Frazier, acting Space Force portfolio acquisition executive for Space-Based Sensing and Targeting, said in a statement that the Space Data Network Backbone will support a broader communications layer for Space Force warfighting systems by keeping “sensors and shooters connected continuously, globally and securely.”
The network will not be built from scratch. It will connect with the Space Development Agency’s Transport Layer program, which is already deploying hundreds of communications satellites in low-Earth orbit.
The Transport Layer is designed to move military data worldwide, while the new Space Data Network Backbone will provide higher-capacity links to move larger volumes of information between sensors, weapons systems, and commanders.
The Space Force has said distributing communications across many satellites, rather than relying on fewer, larger satellites, could allow data to be rerouted if one satellite fails or is attacked.
The agency has not publicly released details including how many satellites SpaceX will deploy or the network’s final architecture.
