US President Donald Trump’s Golden Dome missile defence shield will cost as much as US$1.2 trillion to deploy and operate, six times above current forecasts, according to a new estimate – and would still probably fail to stop an all-out attack.The new forecast from the non-partisan Congressional Budget Office relies on capabilities spelled out in Trump’s January 2025 executive order unveiling the idea rather than any government plan because the administration has given no details about what the system will look like, it said.That makes it “impossible to estimate the long-term cost of the system being contemplated”, CBO said. Golden Dome would be operational for 20 years, the CBO said, but “the system could be overwhelmed by a full-scale attack mounted by a peer or near-peer adversary”.

A new estimate from the Congressional Budget Office (CBO) projects that President Trump's proposed "Golden Dome" missile defense shield could cost up to $1.2 trillion over its 20-year operational lifespan. This figure is six times higher than current forecasts. The CBO's estimate is based on capabilities outlined in a January executive order, as the administration has not provided specific details on the system's design, making long-term cost assessment difficult. Despite the substantial investment, the CBO concluded that the Golden Dome would likely be unable to stop an all-out attack from a peer or near-peer adversary.
