The United States, Britain and Australia announced a year ago a new partnership called AUKUS to provide an Australian fleet of next-generation submarines powered by US nuclear technology.
Australia has yet to decide whether it will opt for the US Virginia-class or British Astute-class model.
Trevelyan described AUKUS as a “deep strategic partnership” that reflected mutual trust and longtime cooperation.
“I am personally committed to ensuring that the whole ecosystem which we have in the UK to build, upskill and maintain our own UK submarine enterprise will be right alongside you and our Australian friends and allies as you start on this complex and technically demanding defence commitment,” Trevelyan told an Australia-United Kingdom Chamber of Commerce forum.
“It’s going to span everything from construction to creating a nuclear engineering skills ecosystem to the training of your sailors to the through-life maintenance support and decommissioning of your AUKUS submarines,” Trevelyan added.
Australian Defence Minister Richard Marles visited Britain’s BAE Systems submarine-building facilities this week and attended the commissioning of the HMS Anson, the fifth of Britain’s new Astute submarines.
Marles announced that the British had agreed to allow “a significant number” of Australian submariners to train and serve on the new fleet.
Australia lacks nuclear expertise, having only one nuclear reactor. The Lucas Heights reactor in Sydney produces nuclear isotopes for medical use.
Trevelyan returns home on Saturday and will introduce legislation to the House of Commons on Tuesday that would make the British-Australian free trade deal law.
