The U.S. Space Force has named 12 companies developing space-based interceptors for the Golden Dome missile defense initiative.
The list includes Anduril Industries, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Lockheed Martin, Northrop Grumman, Quindar, Raytheon, Sci-Tec, SpaceX, True Anomaly, and Turion Space.
The Space Force awarded 20 Other Transaction Authority agreements to these companies in late 2025 and early 2026.
The agreements have a combined maximum value of $3.2 billion.
Officials said the awards fund early-stage development and technology demonstrations, not full-scale production.
Some contractors, such as SpaceX, Lockheed Martin, and Northrop Grumman, are established space industry players.
Others, including Anduril and True Anomaly, are newer entrants with national security ambitions.
Sci-Tec and Quindar contribute software expertise, while Turion focuses on space sensing technology.
GITAI USA began as an in-space robotics company before joining the SBI program.
The Space Force declined to disclose individual company contributions due to operational security.
OTAs enable rapid prototyping by bypassing standard federal acquisition regulations.
How the Golden Dome initiative differs from past missile defense approaches
Golden Dome represents a strategic shift toward space-based interceptors for boost-phase missile defense.
This approach targets adversary missiles shortly after launch, before they exit the atmosphere.
It moves beyond traditional regional defenses to create a persistent, global protective shield.
What happens next in the SBI development timeline
The current phase focuses on prototyping and on-orbit testing in low-Earth orbit.
Full-scale production would follow successful demonstrations and require significantly higher funding.
The Space Force has not announced a timeline for when testing might begin.
Why is the Space Force using Other Transaction Authority for this program?
OTAs allow the Pentagon to attract a broader range of contractors and accelerate prototyping.
Are any of the selected companies new to space-based defense work?
Yes, Anduril Industries and True Anomaly are newer to the space industry but active in national security.
