Space Force has secured a $2.29 billion contract with SpaceX to construct a satellite communications network. The system, the Space Data Network (SDN) Backbone program, aims to advance a “resilient, optically interconnected satellite constellation” in order to provide “secure, high-speed global data transport for the Joint Force.”
The contract will enhance the network with an expanded satellite connection for “world-wide tactical communications and broadband communication services,” Space Force said. The prototype is expected to be completed by the end of 2027.
“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,” stated USSF Col. Ryan Frazier, acting Space Force portfolio acquisition executive for Space-Based Sensing and Targeting (SBST). “The SDN Backbone supports the broader SDN, which acts as a core communications layer for the USSF warfighting systems, ensuring our sensors and shooters are connected continuously, globally and securely.
The technology is believed to be a critical component of the Golden Dome.
In April, the Golden Dome project was believed to be ahead of schedule. “Golden Dome is the decisive response to a new era of threats,” said Gen. Mike Guetlein, the Director of Golden Dome for America. “We are moving with purpose and urgency to forge a shield that is layered, integrated, and automated. The progress on display today is tangible proof that this is not a future concept, but a reality we must build now.”
The project’s initial blueprints are completed, its Command-and-Control Consortium is established, and contracts have been awarded, officials detailed.
