Australia receiving only used nuclear submarines from the US will not change the government's commitment to the AUKUS pact, the foreign minister says.
The $368 billion plan originally had Australia receiving three nuclear submarines from the US - two used and one new Virginia-Class vessels - before building its own in Adelaide.
But after changes to the deal, Australia will now get three used submarines from the US.
Foreign Minister Penny Wong said it did not matter whether the submarines were used or new.
"Whether it's two (used) and one (new) or three, it's the capability that matters," she told ABC Radio on Wednesday.
"We want three submarines to deal with, from the United States, to deal with a capability gap before the AUKUS submarines are to be delivered ... that is the plan."
