Trump announces Golden Dome missile defence project
What Happened
Donald Trump has announced plans to move forward with developing a major new missile defence system, known as the “Golden Dome”.
The system is intended to protect the United States from long-range missile attacks — including those launched from space — and is inspired by Israel’s Iron Dome.
Speaking from the Oval Office, Trump said the aim is to have the system operational before he leaves office. An initial $25bn in funding has been secured from Republican lawmakers, with Canada also expressing interest in joining the programme.
What’s Been Said
Trump stated:
“Once fully constructed, the Golden Dome will be capable of intercepting missiles even if they are launched from other sides of the world, and even if they are launched from space,”
“Forever ending the missile threat to the American homeland.”
Although details remain unclear, Trump said on Tuesday evening:
He had settled on the system’s “architecture” and suggested the final cost could be $175bn, though no specifics were given.
The system will combine ground-based interceptors with space-based defences and is expected to rely on existing technology such as Thaad, Aegis Ashore, and Patriot missiles.
General Michael Guetlein of the US Space Force will lead the project. He is seen within the Pentagon as a highly experienced and capable leader in missile defence.
Defence contractors — including Elon Musk’s SpaceX — are expected to be key partners in the project, especially for launching military payloads and satellites into orbit.
What Next
Trump is choosing between three Pentagon proposals — silver, gold, and platinum-dome options — each with varying timelines and costs.
Though $25bn has been allocated for initial development, the Congressional Budget Office estimates the full cost could reach $540bn over 20 years, depending on the option selected.
The announcement follows a recent Defence Intelligence Agency report highlighting threats from China, Russia and North Korea, with hundreds of intercontinental missiles currently in operation.
Trump signed an executive order shortly after returning to office in January, calling for a “next-generation missile defence shield”, arguing the US system hadn’t significantly evolved in four decades.
