The Space Force announced 12 companies have won contracts totaling up to $3.2 billion to prototype technologies for space-based interceptors in support of the Golden Dome initiative.
Space Force’s Space Systems Command said the companies won 20 total Other Transaction Authority (OTA) contracts in late 2025 and early 2026 and that these agreements “ensure the government maintains contracting flexibility to award to the best provider.”
The OTA winners are Anduril Industries, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA Inc, Lockheed Martin, Northrop Grumman, Quindar Inc, RTX’s Raytheon Company, Sci-Tec Inc, SpaceX, True Anomaly Inc, and Turion Space Corp.
Space Force said the OTAs provide a way for the program office to attract traditional and non-traditional vendors in order to increase competition, “ensuring quality and fostering confidence in the design. This approach is critical to the government’s strategy of leveraging the talent-focused, performance-first mindset that has been developing within the space market over the past few years.”
Last September, the Space Force announced it released a request for prototype proposals for SBIs as part of Golden Dome, with plans to award multiple fixed price OTAs and it said the awards would incorporate prize competitions.
Space Systems Command’s Space Combat Power program executive office had previously sought SBI ideas in four areas, exoatmospheric and endoatmospheric interceptors, common ground elements, and fire control elements.
The Space Force reiterated the SBI program is directed at developing a missile defense interceptor system that can demonstrate capability integrated into Golden Dome architecture by 2028.
It envisions the SBI system as a proliferated Low-Earth Orbit (LEO) constellation of interceptors capable of boost, midcourse, and glide phase engagements.
“Adversary capabilities are advancing rapidly, and our acquisition strategies must move even faster to counter the growing speed and maneuverability of modern missile threats. Utilizing Other Transaction Authority agreements, we attracted both traditional and non-traditional vendors, while harnessing American innovation, and ensuring continuous competition. With the commitment and collaboration of these industry partners, the Space Force will demonstrate an initial capability in 2028,” Space Force Col. Bryon McClain, program executive officer for Space Combat Power, said in a statement.
The Pentagon declined to provide any further information on the contracts “due to operational security requirements regarding the SBI program.”
