CBO Projects Golden Dome Costs at $1.191 Trillion Over 20 Years

The Congressional Budget Office now estimates President Trump’s Golden Dome missile-defense program will total $1.191 trillion across two decades, dwarfing the initial $151 billion contract figure. Roughly $1 trillion is allocated to materiel, including 7,800 space-based interceptors priced at $743 billion, while annual operating costs reach $8.3 billion. Frequent satellite replacements at a 20% annual rate imply about 30,000 launches over the program’s life. Markets reacted with caution, as ballooning expenses and technical hurdles raise cancellation risks for defense contractors despite near-term awards.
