Golden Dome\u2019s official projected price tag just jumped $10 billion to $185 billion. Experts say the real cost is likely to be far, far more.<\/p>\n

Gen. Michael Guetlein, the Space Force officer in charge of the sprawling missile defense project, said Tuesday that it was no longer expected to cost $175 billion, the number given by President Trump when he announced the project last May.<\/p>\n

\u201cWe were asked to procure some additional space capabilities,\u201d Guetlein told attendees at the McAleese Defense Programs Conference. \u201cSo, we are at $185 billion for the objective architecture, which delivers way out into the 2035 timeframe.\u201d<\/p>\n

Experts told Defense One<\/em> it\u2019s most likely going to exceed that figure. Soon after the project was announced, the Congressional Budget Office predicted\u00a0 anywhere from $542 billion to $831 billion over 20 years. In September, an American Enterprise Institute report said the highest-end architecture could mount to $3.6 trillion.<\/p>\n

But Guetlein said he was confident in the new figure.\u00a0<\/p>\n

\u201cThere’s been numerous cost estimates out there in excess of a trillion dollars. I would say the difference between what they are estimating and what we are building is they’re not estimating what I’m building,\u201d he said. \u201cWe are changing that equation for Golden Dome, simplifying it, if you will, just aggregating it, if you will, to bring down that cost equation and not exceed that $185 billion that the President has committed.\u201d<\/p>\n

Todd Harrison, a senior fellow at AEI who has researched Golden Dome\u2019s likely costs, said Guetlein\u2019s $185 billion figure would likely only include a basic capability for space-based interceptors\u2014which has been seen as the most expensive and ambitious part of the project. It\u2019s also, he said, just the beginning of the expenses.<\/p>\n

\u201cMy understanding is that is just the near-term cost to acquire an initial level of capability. It’s not the total acquisition cost, and it does not include long-term operation and replenishment costs,\u201d Harrison said. \u201cIt also is a good indicator that space-based interceptors will be a relatively minor part of the architecture, if they even move out of the demonstration phase.\u201d<\/p>\n

Last year, the Space Force awarded small contracts to companies to develop orbital interceptors and were soliciting proposals for space-based midcourse interceptors, too. Physicists have questioned the project\u2019s use of boost-phase and mid-course space interceptors, claiming it\u2019s impractical against modern missile threats.<\/p>\n

Given Guetlein\u2019s budget estimate, it\u2019s not clear how much space-based interceptors will play a role in the final architecture, said Victoria Samson, the Secure World Foundation\u2019s chief director of space security and stability.<\/p>\n

\u201cReally and truly, it’s not going to be cheap, but the long pole in the tent in terms of cost is going to be the space-based interceptor layer,\u201d Samson said. \u201cThat’s going to be the one that’s going to drive it up, depending how much they decide to go ahead with it.\u201d<\/p>\n

Guetlein admitted that the space-based interceptors are a challenge for the program.<\/p>\n

\u201cWe have not had anything fail yet, we\u2019ve had numerous successful tests that I can only go into in this environment,\u201d Guetlein said. \u201cIf I was to predict where the biggest amount of risk is the space-based interceptor. And it’s not the technology, it’s the scalability and the affordability.\u201d<\/p>\n

The Pentagon is casting a wide net when it comes to Golden Dome-related work. Early this year, the Missile Defense Agency made several announcements that a total of 2,440 applicants have been approved to compete for work totaling up to $151 billion out of an original pool of 2,463, leaving just 23 applicants out of the running.<\/p>\n

Guetlein said that Lockheed Martin, RTX, and Northrop Grumman are three prime contractors working with six other companies to build command and control capabilities, or C2, layer for Golden Dome.<\/p>\n

\u201cNow, we have a team of nine building our command and control capability, which is really a glue layer that sits upon all these other services and agencies, C2 systems,\u201d Guetlein said.<\/p>\n

While Trump\u2019s January 2025 executive order establishing Golden Dome does not establish a due date for the project, a subsequent December 2025 executive order calls for \u201cdeveloping and demonstrating prototype next-generation missile defense technologies by 2028\u201d leaving Guetlein a little more than two years to meet the president\u2019s goals.<\/p>\n

\u201cI do not have a 2028 mandate inside the executive order. However, the President did ask us to rapidly change the defensive equation of the nation as fast as we possibly can, and put a marker on there for the summer of 2028,\u201d Guetlein said. \u201cBy the summer of 2028 I have to demonstrate the ability with operational capability deployed in the field to defend ourselves against those threats as identified in the executive order. That’s what they have asked us to do.\u201d\n\n<\/svg><\/p>\n<\/div>\n
