Giving evidence to an independent public inquiry into the $368bn nuclear agreement with the US and UK on Thursday, Evans, a cabinet minister in the Hawke and Keating governments, will warn the transfer and construction of submarines to Australia from the early 2030s is effectively only an extension of the American military fleet. He says a future US administration would not come to Australia’s aid in the event of an “existential attack” and would only assist in a military conflict if its own assets on Australian soil are threatened. “The notion that extended nuclear deterrence justifies our prostration – that the US really would be prepared to sacrifice San Francisco for Sydney, let alone Miami for Melbourne – is, and always has been, a ludicrous delusion,” Evans says.

He says the complexity and timeline of the second phase of Aukus requires even more “heroic levels of optimism” than is needed for the American vessels. “Every report coming out of the UK indicates that its defence-industrial base is presently under extraordinary stress, with submarine building schedules tightening and costs increasing, and with every prospect of further deterioration, notwithstanding Australia’s commitment to spending $4.5bn over 10 years to help boost production rates.” View image in fullscreen A Virginia-class submarine.
