The U.S. Space Force Space Systems Command has selected Lockheed Martin to develop capabilities for the Space-Based Interceptor (SBI) program, as part of broader efforts to build a layered missile defense system.
Announced on May 1, 2026, from Huntsville, Alabama, the contracts support the integration of SBI technologies into the Golden Dome architecture, a space-based missile defense initiative. These agreements are among 20 Other Transaction Authority contracts awarded to 12 companies, including Anduril Industries, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Northrop Grumman, Quindar, Raytheon, SciTec, SpaceX, True Anomaly, and Turion Space. The total value exceeds $3 billion, aimed at prototyping space-based interceptors.
The work focuses on accelerating development, testing, and integration to deliver an early engagement layer. This layer is designed to expand coverage, improve survivability, and counter emerging missile threats. Lockheed Martin draws on its experience with systems like THAAD, PAC-3, and the Next Generation Interceptor.
Space Force officials expect an initial operational capability by summer 2028, with the Golden Dome architecture’s projected cost rising to $185 billion. The contracts promote competition among traditional and non-traditional vendors to advance homeland defense.
