The US Space Force on Friday released a list of a dozen companies working on space-based interceptors for the Pentagon’s Golden Dome initiative, a multilayer defense system to protect US territory from drone and ballistic, hypersonic and cruise missile attacks.
The roster of Golden Dome space-based interceptor (SBI) contractors, some of which were previously reported, include Anduril Industries, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Lockheed Martin, Northrop Grumman, Quindar, Raytheon, Sci-Tech, SpaceX, True Anomaly, and Turion Space.
The Space Force made 20 individual awards to 12 companies in late 2025 and early 2026 using an acquisition mechanism known as Other Transaction Authorization, or OTA, agreements. OTAs allow the Pentagon to circumvent federal acquisition rules and cast a wide net to attract large numbers of potential contractors, and 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 agreements have a total value of up to $3.2 billion, and will be capitalized by a mix of public and private investments to move SBI closer to testing in low-Earth orbit.
Officials have not released details of each company’s contribution, but contractors come to the SBI program with different skill sets. The agreements are for early-stage development and technical demos, not full-scale production, which would come with a significantly higher price tag.
“Due to operational security requirements regarding the SBI program, no additional information will be available at this time,” the Space Force said in a statement.

Some of the companies on the list, such as SpaceX, Lockheed Martin and Northrop Grumman, are well-known in the space industry. It appears that they are in a position to become the lead or prime contractor. Others, like Anduril and True Anomaly, are full-stack developers who are new to the space industry but have lofty ambitions in the national security market. Sci-Tech and Kwinder have expertise in software. Turians have developed space sensing technology, and GITAI USA started as an in-space robotics company.
