Musk’s SpaceX frontrunner to build Trump’s ‘Golden Dome’ missile defense system: report
Share
Israel’s Iron Dome and aerial defense system is complicated. Thomas Karako, a senior fellow with the International Security Program and the director of the Missile Defense Project at the Center for Strategic and International Studies (CSIS) joined LiveNOW from FOX’s Josh Breslow to explain how it works.
The Brief
WASHINGTON-Afinds that Elon Musk’s SpaceX, along with partners Palantir and Anduril, is among the leading contenders to help build part of President Donald Trump’s “Golden Dome” missile defense shield.
According to Reuters, the companies have pitched a proposal to deploy hundreds of satellites that would detect and track missile threats from space. The bid is reportedly being reviewed by top Pentagon and White House officials and could shape a key part of the multilayered system envisioned by the administration.
What is Trump’s Golden Dome system?
The backstory:
In January 2025, Trump signed an executive order directing the military to develop a plan for what would become the “Golden Dome”—a space-based missile defense system capable of destroying missiles within seconds of launch.
According to previous reporting by the Associated Press, the project was initially referred to as “Iron Dome” but was renamed in February. Israel is known for its Iron Dome system, which intercepts short-range rockets and artillery from the ground. Trump’s Golden Dome draws inspiration from the name but envisions a far more ambitious goal: deploying interceptors in space to neutralize long-range missile threats. If completed, it would mark the first time the U.S. places missile interceptors in orbit.
At the Space Symposium in Colorado earlier this month, U.S. Space Command said it had finalized options for the system and submitted them to Defense Secretary Pete Hegseth. General Stephen Whiting, the head of Space Command, said, “We need orbital interceptors. We call these weapons, and we need them to deter a space conflict.”

Trump’s 2026 defense budget proposal is expected to near $1 trillion, with Golden Dome projected to absorb a significant portion of that funding.
What role would SpaceX play in the system?
What we know:
According to Reuters, SpaceX has proposed building the “custody layer” of the system—a constellation of 400 to 1,000 satellites that would detect missiles and track their trajectory. Two sources familiar with the proposal told Reuters that the early design and engineering costs are estimated between $6 billion and $10 billion.
The satellites would not be weaponized, sources said. A separate fleet of about 200 armed satellites is being considered for the intercept role, but that part of the system would be handled by other contractors.
Why is the proposed model raising concerns?
The other side:
Reuters reports that SpaceX has proposed delivering its portion of the system under a “subscription model”, meaning the government would pay for access but wouldn’t own the technology.
While such an arrangement wouldn’t violate Pentagon rules, it has sparked internal concerns. Some officials worry it could leave the government reliant on private infrastructure with limited control over pricing and updates, according to two sources cited by Reuters.
What they’re saying:
“When the richest man in the world can become a Special Government Employee and exert influence over the flow of billions of dollars of taxpayer money in government contracts to his companies, that’s a serious problem,” U.S. Senator Jeanne Shaheen (D-NH) told Reuters.
Shaheen, a senior member of the Senate Armed Services Committee, has introduced legislation to block companies owned by special government employees from receiving federal contracts.
U.S. Rep. Donald Beyer (D-VA) also raised alarms, telling Reuters that “any contracts awarded to him, or his companies, are suspicious,” citing Musk’s access to non-public information.
Is the bid guaranteed to win?
What we don’t know:
While Reuters reports that the SpaceX-led proposal has drawn significant interest, the selection process is still in early stages and may change as the Pentagon finalizes requirements.
More than 180 companies have submitted bids to work on the Golden Dome system, according to the AP, including legacy defense firms like Boeing, Northrop Grumman, Lockheed Martin, and RTX.
Defense Secretary Peter Hegseth has asked Pentagon leadership to accelerate deployment timelines, and Space Command is reportedly working to match system requirements with commercially available tech.
