CBO Estimates Trump's Golden Dome Missile Defense Program Will Cost $1.2 Trillion

The Congressional Budget Office estimates the Golden Dome program will cost $1.2 trillion over two decades, significantly higher than the initial $175 billion estimate.
Acquisition costs alone are projected to exceed $1 trillion, including for interceptor layers and a space-based missile warning system.
Concerns remain about the program's ability to effectively defend against advanced threats from adversaries like Russia and China.
