US Space Force confirms SpaceX will build sensor-to-shooter targeting network

SpaceX has won a lucrative contract to provide the US military with a means of distributing space-based sensing and targeting data, forming the "backbone" of a rearchitected network after separate Pentagon initiatives stalled, officials announced Tuesday.

Space Systems Command, the Space Force's primary procurement and acquisition center, announced the $2.29 billion firm-fixed-price agreement, confirming long-simmering reports that the Pentagon was likely to tap SpaceX for a new communications network in low-Earth orbit. SpaceX's selection for the Space Data Network (SDN) Backbone contract "accelerates the delivery of a resilient, high-speed communications network in space," Space Systems Command said in a statement.

The network will be based on technology originally developed for SpaceX's Starlink global Internet constellation. SpaceX already builds and launches specially designed satellites, called Starshield, for military applications. The SDN Backbone network in low-Earth orbit (LEO) will presumably use the Starshield platform.
