U.S. Space Force secures $1.2B to upgrade missile warning and data relay tech

The U.S. Space Force has secured $1.2 billion in new funding to upgrade its data relay and missile warning systems. The investment comes as part of the 2026 National Defense Authorization Act, which allocates $16.6 billion for Space Force research and development. Officials aim to strengthen national security through improved satellite networks and tracking technology.

A significant portion of the funding—$500 million—will go toward Tranche 3 of the Space Development Agency’s Transport Layer. This phase is expected to reshape how the Space Force handles data transmission in low-Earth orbit. The agency’s design, along with a lesser-known system called MILNET, is also under review for future data relay satellites.

The remaining funds are split between two key areas. An additional $474 million will support the polar segment of the Next-Generation Overhead Persistent Infrared (OPIR) system. Another $474 million is earmarked for enhancing the broader Next-Gen OPIR programme, pushing its total budget close to $1.2 billion. These upgrades will sharpen the Space Force’s ability to detect and track missile threats. Multiple companies are set to supply spacecraft and ground terminals for the new data relay system. Currently, SpaceX remains the only confirmed contractor for this part of the project. The combined investments will boost both missile warning capabilities and the resilience of space-based communication networks.

The funding will directly improve the Space Force’s ability to monitor threats and relay critical data. With $1.2 billion now dedicated to these upgrades, the agency is set to enhance its missile tracking and satellite communication systems. The changes align with broader efforts to modernise national defence infrastructure in space.
