A new CBO analysis estimates President Trump's "Golden Dome for America" missile defense initiative could cost $1.2 trillion over 20 years, significantly exceeding prior projections. The vast majority of this cost is attributed to deploying 7,800 space-based interceptor satellites to counter evolving global threats.

President Donald Trump's plan to put weapons in space, called the “Golden Dome for America” missile defense program, is estimated to cost much more than he originally said.

The CBO report is described as an analysis that reflects “one illustrative approach rather than an estimate of a specific Administration proposal."

Congress has only allocated $24 billion so far.
