CBO Estimates Golden Dome at $1.2 Trillion, Space-Based Interceptors Biggest Cost
The Congressional Budget Office issued an updated estimate today of the cost of President Trump’s Golden Dome missile defense system. Lacking detailed data from the Administration, CBO based its analysis on the capabilities called for in Trump’s January 2025 Executive Order and concluded the total cost over 20 years is $1.2 trillion, about twice its estimate last year, with the bulk of it for Space-Based Interceptors.
