Twenty contracts worth a potential $3.2 billion have been issued to a dozen companies to build space-based interceptors for President Donald Trump’s Golden Dome missile defense plan, the Space Force announced on April 25, 2026.
Dozen firms tapped to build prototypes
The Space Force disclosed that 20 awards, spread across 12 companies, were issued over the last several months under a dedicated space-based interceptors (SBI) program. The firms named in the release are:
- Anduril Industries Inc.
- Booz Allen Hamilton Inc.
- General Dynamics Mission Systems Inc.
- GITAI USA Inc.
- Lockheed Martin
- Northrop Grumman
- Quindar Inc.
- Raytheon (also known by its parent company RTX)
- Sci-Tec Inc
- SpaceX
- True Anomaly Inc.
- Turion Space Corp.
The announcement did not disclose the individual value of each contract or the specific roles each company will play. The Space Force said it would not release additional information at this time, citing operational security.
What the SBIs are supposed to do
According to the Space Force, the SBIs will form a "proliferated low earth orbit constellation of interceptors capable of boost, midcourse and glide phase engagements." In plain terms, the intended capability is for these space-based systems to intercept missiles — including hypersonic glide vehicles that can maneuver — during earlier phases of flight.
The service framed the approach as an integration of "proven and formidable U.S. missile defense systems, combined with next-generation space-based tracking and advanced interceptors" and specified that this architecture must be "integrated with Artificial Intelligence to counter the speed, maneuverability, and lethality of the threats," according to the Space Force release.
Procurement method and the push for innovation
The contracts were issued as Other Transaction Awards. Space Force Col. Bryon McClain said that the OTA mechanism "attracted both traditional and non-traditional vendors, while harnessing American innovation, and ensuring continuous competition." That phrasing underlines an explicit effort by the service to widen the contractor base beyond legacy primes.
Operational security remains a constraint on public disclosure: the Space Force declined to release more granular program details at this stage.
Timeline, program cost framing, and decision points
The Space Force said it expects SBIs "should be ready for demonstration in as little as two years" and that it intends to show "an initial capability in 2028," according to program office comments. Those two milestones set concrete near-term and mid-term targets for demonstrations and limited capability.
The SBI effort sits inside the broader Golden Dome program, which the article said has an estimated price tag of $185 billion. Golden Dome’s lead coordinator, Space Force Gen. Michael Guetlein, recently emphasized to lawmakers the need to show progress to the American public on the overall project and warned that the SBIs "may not make it into the final Golden Dome architecture if it is shown to be prohibitively costly." As Guetlein put it, "We are so focused on affordability. If we cannot do it affordab[ly], we will not go into production."
What this means for defense contractors, policymakers, and the public
- Defense contractors and innovators: The OTA approach and the mix of legacy and non-traditional firms named signal an invitation to compete on rapid prototyping and novel concepts; companies named will be judged on their ability to deliver demonstrable intercept capability in the short window the Space Force has set.
- Policymakers and budget overseers: With a 2028 initial capability target and a program-level estimate of $185 billion for Golden Dome, lawmakers will face concrete demonstration milestones and cost points to assess whether SBIs are affordable enough to enter production.
- The American public and operators: The Space Force’s emphasis on integrating AI with space-based tracking and interceptors frames what operators will need to train for; at the same time, the service’s withholding of detailed information for operational security will limit what can be publicly shown ahead of demonstrations.
The Space Force has set a compact timetable and a high bar: demonstrate prototypes in as little as two years and decide whether to accept SBIs into a far larger, $185 billion architecture before moving to production. The agency has marshaled both established primes and newer entrants through Other Transaction Awards, and it has publicly placed cost — in Gen. Michael Guetlein’s words, "affordability" — at the center of whether space-based interceptors become a permanent part of Golden Dome.
