CBO: Trump’s “Golden Dome” missile defense could cost ~$1.2T over 20 years, with space-based interceptors the biggest driver

The Congressional Budget Office estimates a national missile defense architecture broadly aligned with President Trump’s “Golden Dome” executive order would cost about $1.2 trillion over the next two decades. The CBO report says space-based interceptors are the largest cost component—far above the Pentagon’s public estimate of roughly $185 billion.

Briefing

What Hype is tracking

  • CBO’s $1.2 trillion (20-year) price point—especially the emphasis on space-based interceptors—reshapes the affordability baseline for Golden Dome design tradeoffs discussed in prior coverage of boost-phase cost concerns (Space Force warns Golden Dome…).
  • The gap versus the Pentagon’s public ~$185 billion estimate raises near-term risk for budgeting, contracting, and program pacing across the air-and-missile defense kill chain.
  • The estimate adds context to how “Golden Dome” is being operationalized through a broader defense–space industrial push, including software support (SpaceX tapped to help build software…).
