Golden Dome Missile Shield Cost Varies Wildly Due to Undefined Mission

The article analyzes the massive cost uncertainty surrounding the U.S. Golden Dome missile defense program. President Trump promised $175 billion, the program's general says $185 billion, but the Congressional Budget Office estimates $1.2 trillion over 20 years. The core issue is that the Pentagon has not defined what threat the shield is meant to counter. The CBO report reveals the space-based layer of 7,800 interceptors could engage only about ten targets simultaneously due to orbital mechanics. Experts like Todd Harrison calculate that a trillion dollars buys enough to defeat just five boost-phase missiles, fifty hypersonic gliders, and fifty midcourse warheads—against adversaries with thousands of warheads. The program's funding is fragile, relying on future reconciliation packages, and faces congressional resistance within a record $1.5 trillion defense request.
