Trump Announces the Golden Dome Missile Defence Shield
- Trump announced Golden Dome in the Oval Office on Tuesday 20 May 2025, saying it would cost $175 billion and would be 'capable even of intercepting missiles launched from the other side of the world, or launched from space'[1]
- It is meant to counter ballistic, hypersonic and cruise missiles with space-based sensors and interceptors, partly inspired by Israel's Iron Dome[1]
- Trump said Canada wanted to join; the Congressional Budget Office had put the space-based part alone at up to $542 billion over 20 years[1]
- Trump said it would be finished within three years; Space Force General Michael Guetlein took charge of the programme on 21 July 2025[2]
- Congress provided $24.4 billion in the 2025 reconciliation act and $13.4 billion in FY2026 appropriations; in March 2026 Guetlein raised the estimate to $185 billion[2]
- In May 2026 the CBO estimated about $1.2 trillion to build and run the system over two decades and warned it might not stop an all-out attack[3]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
