Golden Dome got $23 billion, but lawmakers still don’t know how it will be spent

When the Defense Department received a $23 billion down payment for the Golden Dome initiative through a reconciliation bill, lawmakers demanded a detailed plan for how the Pentagon plans to spend that money.

Six months later, lawmakers are still waiting for the Pentagon to provide “complete budgetary details and justification of the $23,000,000,000 in mandatory funding.” That includes a comprehensive deployment schedule, cost, schedule and performance metrics and a finalized system architecture. 

As a result, Congressional appropriators were unable to conduct oversight of Golden Dome programs for fiscal 2026.

The department’s $175 billion Golden Dome initiative President Donald Trump first ordered last January aims to build a network of satellites — possibly numbering in the hundreds or even thousands — that would detect, track and intercept incoming missiles. Pentagon officials have described the program as a “top priority for the nation.”

The effort has been shrouded in secrecy, and lawmakers’ demand for more detail on how the Pentagon plans to spend the initial tranche of funding is another sign of Congress’s limited visibility into the program’s early spending plans.

“Due to insufficient budgetary information, the House and Senate Defense Appropriations Subcommittees were unable to effectively assess resources available to specific program elements and to conduct oversight of planned programs and projects for fiscal year 2026 Golden Dome efforts in consideration of the final agreement,” appropriators wrote.

Elaine McCusker, senior fellow at the American Enterprise Institute, said it is not unusual or surprising for lawmakers to seek complete budget information for a complex program like the Golden Dome that pulls in multiple complex ongoing efforts and includes classified components.

“Congress often requests new budget exhibits and supplementary information for evolving, complicated programs with potentially high price tags so they can better understand what is existing and ongoing funding and what is really new or accelerated in the budget request,” McCusker told Federal News Network.

But Greg Williams, director of the Center for Defense Information at the Project on Government Oversight, said Congress’ request for complete budgetary information highlights a broader challenge with how the administration has rolled out major initiatives without providing sufficient detail.

“Golden Dome is an extraordinarily complex and ambitious program, for which we should expect extraordinarily comprehensive information. Instead, the American people and Congress have the opposite. The fiscal 2026 Defense Appropriations Act and its explaining document appear to appropriately reflect that disparity,” Williams told Federal News Network.

The House passed the final 2026 minibus funding package Thursday, which includes money for the Defense Department. If the spending bill becomes law, Defense Secretary Pete Hegseth, along with Gen. Michael Guetlein, the Golden Dome director, will have two months to provide a comprehensive spend plan for the initiative. Lawmakers want to see planned obligations and expenditures by program, descriptions, justification and the corresponding system architecture mission areas for fiscal 2025 through 2027. 

The Pentagon comptroller would also have to submit a separate budget justification volume annually beginning in fiscal 2028.

McCusker said Congress bears some responsibility for the delay — budget uncertainty has complicated the department’s efforts to develop the program.

“The Pentagon is pursuing new ideas in how it partners with industry to rapidly develop, build and deploy the myriad systems that make up Golden Dome while also navigating annual delays and uncertainty in getting its budget,” she said. “Congress has an understandable thirst for information on high profile defense programmatic priorities and may perceive a delay in getting the level of detail it seeks, but failing to pass annual appropriations on time has become so common it is a perpetual factor to mitigate. Congress has to accept responsibility for this and be willing to take some risk in providing funds in advance of all the information it needs.”

President Donald Trump said in May that the Golden Dome’s architecture had been “officially selected,” but details about the initiative remain scarce and the Pentagon has restricted officials from publicly discussing the initiative.

McCusker said that Congress’ request for detailed planning, performance and budget information doesn’t say much about the program itself other than “its level of complexity and maturity and the need to develop and convey the overall strategy and projected timeframe for its execution.”

There is no single “Golden Dome” line item in the 2026 spending bill, though it includes billions for related programs that will most likely support the broader system.

The Pentagon leadership received its first official briefing on the Golden Dome architecture in September, and an implementation plan was expected to be delivered in November.

Williams said producing a detailed plan of this complexity in a short period of time is understandably difficult, but added that crafting a plan that credibly explains how its goals will be achieved is “likely impossible according to many experts.”

“Golden Dome is a program of unprecedented, arguably reckless, complexity and ambition.” Williams said. 

“The lack of information is also a result of Congress’s choice to use reconciliation to increase defense spending: The reconciliation process does not provide for the formal submission of budget request materials from the executive branch and so risks exactly this kind of lack of information. Congress should return to the statutory process for clean Defense authorization and appropriations acts to ensure adequate information,” he added.
