The U.S. Space Force has lined up a dozen contractors to build one of the most technically ambitious — and unproven — pieces of President Trump's Golden Dome missile shield: weapons that would sit in orbit and strike enemy missiles in flight. The awards, worth up to $3.2 billion combined, went to 12 companies including SpaceX, Lockheed Martin, Northrop Grumman and RTX's Raytheon, the Space Force said.
What Golden Dome is
Golden Dome is the administration's layered national missile-defense initiative, announced in May 2025, intended to detect and destroy ballistic, hypersonic and cruise missiles before they reach the United States. The most novel layer is the space-based interceptor — a planned constellation of satellites in low-Earth orbit carrying interceptors designed to hit an enemy missile during its early "boost" phase, before it can release warheads or decoys.
No country operates such a system today, and defense analysts have long debated whether it is technically and financially feasible. The contracts announced are for prototypes: each company must demonstrate a capability, with an initial test targeted for 2028. Production contracts, if any, would follow.
Who got the work — and how
The Space Force named 12 awardees: SpaceX, Lockheed Martin, Northrop Grumman, Raytheon (RTX), Anduril Industries, General Dynamics, Booz Allen Hamilton, GITAI USA, Quindar, Sci-Tec, True Anomaly and Turion Space, according to Fortune. The notable feature of the list is how many entrants are relatively young commercial space and defense startups, not just the traditional prime contractors.
That is by design. The awards use Other Transaction Authority, a fast-track contracting mechanism that sidesteps much of the standard federal procurement process and is meant to draw commercial firms into defense work. Companies fund early prototyping themselves and compete for the larger contracts that follow. The Space Force did not break out individual dollar figures within the $3.2 billion pool.
Rocket Lab, which is not a prime on the interceptor program, said it had been selected to work with Raytheon on its prototype — the first named subcontractor relationship to surface publicly. Separately, Rocket Lab already holds an $816 million prime contract from the Space Development Agency to build 18 missile-tracking satellites, part of a roughly $3.5 billion award shared with Lockheed Martin, L3Harris and Northrop Grumman.
About that "space laser"
Some coverage has described the effort as a "space-laser" project. The interceptors themselves are, per the program's public baseline, kinetic — they physically collide with their targets — not directed-energy laser weapons. The laser element refers to something different: the optical inter-satellite links that SpaceX's Starshield network (a classified version of Starlink) uses to pass targeting data between satellites at high speed without routing through the ground. Those laser data links are expected to form the sensing-and-communications backbone that ties the system together. No contracts for space-based laser weapons have been publicly disclosed.
What it means for investors
Golden Dome is enormous and contested in cost. The White House has cited $175 billion; the Congressional Budget Office has estimated $161 billion to $542 billion over 20 years. Congress appropriated $13.4 billion for space and missile defense in the fiscal 2026 defense bill, and the Pentagon's fiscal 2027 request included $17.5 billion for the program.
For the contractors, the structure marks a shift in how the Pentagon buys space hardware — favoring speed and commercial competition over the traditional, prime-dominated model. Rocket Lab, in particular, now has a stake across sensing, tracking and interception, validating its push from a launch company into integrated defense hardware. For the legacy primes, the program preserves their role while exposing them to a wave of newer, hungrier rivals. The bigger question hanging over all of it is technical: whether an orbiting interceptor layer can be made to work at all — and the 2028 demonstration is the first real test of that.
