Australia, Britain to strike treaty for joint production of submarines

SYDNEY - Australia and Britain said they would strike a bilateral treaty to produce a new class of nuclear-powered submarine, under the AUKUS partnership which also includes the United States.

Australia will buy US Virginia class nuclear-powered submarines from the United States in the next decade, with Britain and Australia later building a new class of AUKUS submarine at Barrow-in-Furness in Britain, and in South Australia, under the AUKUS pact announced in 2023.

"We will be negotiating a treaty, a bilateral treaty, between Australia and the UK to enable our portion of AUKUS," Australian Defense Minister Richard Marles told reporters after a meeting with his British and US counterparts on Thursday in London.

"We will be operating the same class of submarine. So when you look at the industrial cooperation, the technology transfer, the way in which all of those mechanisms operate to do that, that is the subject of the treaty," he added.
