The U.S. Space Force named twelve companies developing orbital interceptors for the Pentagon’s Golden Dome program, a layered defense system meant to counter drones, ballistic, hypersonic and cruise missiles.
The list, released Friday, includes established aerospace giants like Lockheed Martin, Northrop Grumman and SpaceX, as well as newer entrants such as Anduril Industries and True Anomaly, which specialize in full-stack defense technology and software-driven space systems.
Sci-Tec and Quindar contribute software expertise, while Turion Space focuses on space sensing and GITAI USA brings in-space robotics experience from its origins as a robotics-focused startup.
The Space Force issued 20 individual Other Transaction Authority (OTA) agreements to these companies in late 2025 and early 2026, with a combined potential value of up to $3.2 billion.
OTAs let the Pentagon skip standard federal procurement rules, enabling faster prototyping and a broader vendor pool—exactly what the Space Force wants for the early phase of Golden Dome’s Space-Based Interceptor (SBI) development.

These agreements fund early-stage technology demonstrations, not full-scale production, which would require significantly more funding if the interceptors ever progress beyond testing.
The Space Force declined to disclose each company’s specific role, citing operational security, but confirmed the contractors were selected for their diverse technical strengths in areas like propulsion, autonomy, sensor fusion and on-orbit manufacturing.
Golden Dome remains a conceptual architecture for now, with no guarantee the orbital interceptors will be built or deployed, though the OTA awards signal serious investment in proving the feasibility of space-based missile defense.
If successful, the program could shift part of the U.S. Missile defense strategy from ground- and sea-based systems to orbit, though technical, cost and arms control challenges remain substantial.
What is the Golden Dome program?
Golden Dome is a Pentagon initiative to create a multilayered defense system capable of intercepting drones, ballistic, hypersonic and cruise missile threats using a combination of land, sea, air and space-based components.
Why are OTAs being used for this phase?
The Space Force is using Other Transaction Authority agreements to accelerate prototyping, avoid traditional procurement delays and attract a wider range of contractors, including non-traditional defense firms, for early technology demonstrations.
