SpaceX receives $2.29 billion military order to build low Earth orbit satellite network

The U.S. Space Force announced the award of a fixed-price contract worth $2.29 billion to SpaceX for the construction of a satellite communication network.

This Space Data Network (SDN) aims to connect military sensors and weapons platforms worldwide, possessing high-capacity and low-latency data transmission capabilities. According to contract requirements, SpaceX must deliver a fully operational prototype system by the end of 2027.

The network is the infrastructure of the Trump administration's "Golden Dome" missile defense initiative. SDN will provide crucial communication pathways to transmit data from missile warning and tracking sensors to interceptors in near real-time. Ryan Frazier, the acting program procurement executive for the Space Force, stated that the project leverages commercial innovation, providing robust support for military missions.

From a technical architecture perspective, the SDN backbone network consists of a constellation of low Earth orbit (pLEO) satellites, forming a global communication grid. It will work in conjunction with the U.S. Space Development Agency's transportation layer to build a unified data transmission architecture for the U.S. Department of Defense.

The contract comes as SpaceX is preparing for its initial public offering. Although SpaceX has secured the core share of this network, the U.S. Space Force still plans to introduce more contractors this summer to be responsible for satellite construction and other components of the network.
