This is who’s developing Golden Dome’s orbital interceptors—if they’re ever built
The US Space Force on Friday released a list of a dozen companies working on space interceptors for the Pentagon’s Golden Dome initiative, a multi-layered defense system intended to protect the US homeland from drones and ballistic, hypersonic and cruise missile attacks.
The list of Golden Dome Space-Based Interceptor (SBI) contractors, some of which have been previously reported, 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 individual awards to the 12 companies in late 2025 and early 2026 using an acquisition mechanism known as Other Transaction Authority, or OTA, agreements. OTAs allow the Pentagon to bypass federal acquisition regulations and cast a wide net to attract a larger number of potential contractors. They are particularly useful for rapid prototyping. This is exactly what the Space Force wants to see with the first phase of the SBI program.
The deals have a combined value of up to $3.2 billion and will capitalize on a combination of public and private investments to bring SBIs closer to testing in low Earth orbit.
Officials did not disclose details of each company’s contribution, but entrepreneurs participate in the SBI program with different skill sets. The deals are for early development and technology demonstrations, not large-scale production, which will carry a significantly higher price.
“No additional information will be available at this time due to operational security requirements regarding the SBI program,” the Space Force said in a statement.
The usual players
Some of the companies on the list, such as SpaceX, Lockheed Martin, and Northrop Grumman, are well-known in the space industry. They seem positioned to become prime contractors. Others, like Anduril and True Anomaly, are full-stack developers newer to the space industry but with big ambitions in the national security market. Quindar and Firefly Aerospace subsidiary SciTec have software expertise. Turion is developing space sensing technology and GITAI USA debuted as a space robotics company.
