On January 27, 2025, one week into his second term, Donald Trump signed Executive Order 14186. He called it “The Iron Dome for America”, borrowing the name of the Israeli system that knocks rockets out of the sky over Tel Aviv. Within weeks the iron had become gold: in February the administration renamed the project “Golden Dome for America”. Rulers like to name their walls, and they like the names to shine.
Now the name is in danger of outlasting its welcome. “There’s no doubt that whatever it’s going to be called, it won’t be called Golden Dome,” reads the line set at the top of a report by Stephen Clark in Ars Technica, which canvassed half a dozen current and former officials in industry and government before and after last week’s congressional elections. Their view: when Democrats take over writing the Pentagon’s budget, they will cap the program’s money, try to remove its most contested part, and give it a different name.
Bought on a single vote
The shield was political from its first day. Its opening tranche, about $24 billion, rode inside the “One Big Beautiful Bill” together with other White House priorities, and passed on a party-line vote through reconciliation. That shortcut skipped the ordinary defense budgeting process, in which both parties usually have a hand.
Even friends winced. “This should have been on a bipartisan basis,” Sen. Mike Rounds, the South Dakota Republican, said at a hearing in September. This year Republicans in Congress turned down the administration’s attempt to add $350 billion to the Pentagon budget by the same route.
The departing
Soon after the program was unveiled, lawmakers formed a “Golden Dome Caucus”. Every member was a Republican. Seven of its House members either lost in the 2026 midterms or did not run again. Among them are the caucus co-chair, Rep. Jeff Crank of Colorado, and Rep. Scott DesJarlais of Tennessee, who chairs the House subcommittee that oversees the program. Both had been among its loudest supporters.
On the other side of the aisle, the ranking Democrat on the House Strategic Forces subcommittee, Rep. Moulton of Massachusetts, is retiring. Next in seniority is Rep. John Garamendi of California, who could take the chair in January. Earlier this year he called Golden Dome a “massive, extraordinarily expensive, and ultimately inadequate defensive system.”
John Plumb, who supervised military space policy in the Biden administration, put the cost of the gold paint plainly at the CyberSat conference this week: “When you use the words Golden Dome, now it’s political, and when you politicize national security, you get a political response, so it is damaging.”
The arithmetic
The administration says the shield will cost $185 billion over ten years. With so little published about how it is supposed to work, that figure is hard to check. In May the Congressional Budget Office, pricing a notional system that would meet the executive order’s demands, arrived at about $1.2 trillion over 20 years. Most of that money would go to the orbiting layer: by the CBO’s reckoning, as The War Zone reported, 7,800 space-based interceptors at $22 million apiece, each lasting about five years before it has to be replaced. Last year the American Enterprise Institute published a menu of designs ranging from roughly a quarter of a trillion dollars without space interceptors to $3.6 trillion at the top.
Pentagon officials dispute these numbers, saying they ignore the military’s assumptions about cheap launches and mass-produced satellites.
Star Wars, again
The military imagines hundreds of Space-Based Interceptors at the least, perhaps thousands, circling in orbit and waiting for an attack. None has ever been launched, though the idea has been studied for decades, at least since Ronald Reagan’s Strategic Defense Initiative, which people called “Star Wars”. Trump’s order invokes that program by name and notes that it was cancelled before it reached its goal.
Sen. Mark Kelly of Arizona, a former Navy combat pilot and astronaut, told a hearing this year that “the cost, the physics, the likely reliability, in my view, do not support a full-scale space-based intercept architecture.” He went on: “This means that we could spend more than a trillion dollars and end up with a system that’s not going to work, and it’s not going to meaningfully improve our security.”
Frank Kendall, Biden’s Air Force secretary, warned of a different danger: “It motivates the other side to just build more missiles because the easiest way to overcome a defense like that is just to buy more.” Others fear weapons in space. That worry was raised against Star Wars too, and in September Air Force Secretary Troy Meink disclosed publicly for the first time that the Space Force already has weapons in orbit.
Military officials have also suggested in recent months that they may retreat from one thing Trump asked for: the ability to destroy missiles in their boost phase, soon after launch.
Take the gold off and much of what is left is older than the name. The satellites and radars that detect and track launches are already in service or were in development under earlier presidents. Ground-Based Interceptors have stood guard for decades. Under Biden, the Missile Defense Agency gave Lockheed Martin a $17 billion contract to develop the next generation of them. The order mostly gathered existing efforts under one roof, sped up some of them, and added the orbiting layer on top.
The empty till
The $24 billion was a one-time payment for fiscal year 2026, which ended on October 1. The government now runs on a continuing resolution, which extends last year’s regular defense budget. That budget never contained the reconciliation money, so last month Golden Dome’s funding ran dry. If the preliminary House and Senate bills for fiscal 2027 pass unchanged, they would provide only a fraction of the more than $17 billion the administration requested.
Once again the White House placed a large part of its record $1.5 trillion defense request outside the regular appropriations process, in a $350 billion reconciliation supplement that included Golden Dome money. A Republican Congress let it die. A Democratic one will not bring it back.
The order Trump signed in January 2025 contains a standard clause: it is to be carried out “subject to the availability of appropriations.” For twenty-two months the clause was a formality. From January it will decide what becomes of the program.
