Congressional Estimate: "Golden Dome" Missile Defense to Cost $1.2 Trillion Over Two Decades

The Congressional Budget Office (CBO) has estimated that the proposed national missile defense system, known as "Golden Dome," will require approximately $1.2 trillion for its development, deployment, and operation. This substantial cost is projected over a twenty-year period, highlighting the immense scale of this defensive undertaking. According to a report by the office, the national missile defense system's capabilities are designed to align broadly with those outlined in a specific executive order. The report further detailed that the system will comprise four interceptor layers: one space-based layer, two wide-range surface layers, and one land-based regional sectoral layer.
