Pentagon Rejects CBO's $1.2 Trillion Cost Estimate for Golden Dome Missile Shield

The Pentagon has strongly disputed a Congressional Budget Office (CBO) estimate projecting the 20-year cost of the Golden Dome missile defense program at $1.2 trillion. General Michael Guetlein, director of the project, argued that the CBO’s figures rely on inaccurate assumptions rooted in early 2000s point-defense architectures rather than the modern regional and homeland defense strategy currently envisioned. The CBO report, based on a January 2025 executive order by President Donald Trump, modeled a notional system featuring a costly space-based interceptor constellation. However, Guetlein stated that space-based interceptors are not guaranteed components and emphasized the program's focus on affordability and scalability. He noted that the Defense Department’s internal projection is significantly lower at $185 billion over ten years. The general criticized the CBO for failing to consult with the program office and highlighted ongoing efforts to drive down costs through industrial innovation, including AI and advanced manufacturing. Currently, the Space Force has awarded contracts to develop these capabilities, with integration expected by 2028, aiming to protect the U.S. from hypersonic and ballistic missile threats.
