Trump's 'Golden Dome' Missile Defense System to Cost $1.2 Trillion

President Donald Trump's futuristic "Golden Dome" missile defence system will cost about $1.2 tn (£882bn) to develop, deploy and operate over two decades, a new report from the nonpartisan Congressional Budget Office estimates. That figure is significantly higher than the initial sum of $175bn (£129.25bn) that had been earmarked. Acquisition costs alone would be over $1tn, including for the interceptor layers and a space-based missile warning and tracking system, the watchdog said in a report published on Tuesday. The "Golden Dome", which aims to encompass the US, is designed to counter aerial threats to the US, including ballistic and cruise missiles. Just days after returning to the White House in January, Trump unveiled his plans for the system, aimed at countering "next-generation" aerial threats. He said last year that the programme would require an initial investment of $25bn, with a total cost of $175bn over time. Democratic Senator Jeff Merkley, who requested the estimate in the report, said on Tuesday: "The President's so-called 'Golden Dome' is nothing more than a massive giveaway to defense contractors paid for entirely by working Americans." There have been doubts about whether the US will be able to deliver a comprehensive defence system for such a huge land mass. Officials have warned that existing systems have not kept pace with increasingly sophisticated weapons possessed by potential adversaries. The new Congressional Budget Office report warned that the system could be "overwhelmed" by a full-scale attack mounted by Russia or China. An executive order calling for the creation of what was initially termed the "Iron Dome for America" noted that the threat of next-generation weapons has "become more intense and complex" over time, a potentially "catastrophic" scenario for the US. A week into his second term, Trump ordered the defence department to submit plans for a system that would deter and defend against aerial attacks, which the White House said at the time remain "the most catastrophic threat" facing the US.
