The “Golden Dome,” the anti-missile defense system for the United States wanted by Donald Trump, could cost approximately $1.2 trillion over 20 years, estimated the Congressional Budget Office on Tuesday. In 2025, the American president announced plans to develop this anti-missile shield based on the Israeli “Iron Dome” model, with deployment before the end of his term in 2029.
At that time, he estimated the total cost to be “about $175 billion once completed.” However, many experts then pointed out that the project was unrealistic and redundant given the current missile defense systems in place in the United States.
The most costly component is space
In a report published on Tuesday by the Congressional Budget Office (CBO), the independent parliamentary agency estimates that a national missile defense system with capabilities broadly aligned with those demanded by Donald Trump “would cost about $1.2 trillion to develop, deploy, and operate over 20 years.” According to the CBO, the space component of the system would represent nearly 60% of the total costs.
Like the Strategic Defense Initiative (SDI) or “Star Wars” launched by Ronald Reagan in the 1980s, the “Golden Dome” – or “Golden Dome” – aims to position interceptor satellites in space. The goal is to rapidly destroy any intercontinental ballistic missile heading towards the American territory. China and Russia strongly opposed this project by Donald Trump last year.
