SpaceX has secured a $2.29 billion contract from the US Space Force to build the Space Data Network Backbone, a secure, high-speed military satellite communications network using low-Earth-orbit satellites with optical links. The prototype is due by end of 2027. This network is part of the Pentagon's modernization efforts, including the 'Golden Dome' missile defense architecture, which requires real-time connectivity between satellites, sensors, and interceptors. The contract underscores SpaceX's deepening role in US national security infrastructure. The Space Data Network program is expected to receive billions more in funding. Potential beneficiaries of rising military space spending include Rocket Lab, Northrop Grumman, Lockheed Martin, RTX, Boeing, L3Harris, Viasat, Iridium, Firefly, and York Space Systems. The shift from few expensive satellites to large, resilient satellite networks creates long-term opportunities.
