Under the $368 billion agreement, Australia will acquire three Virginia-class submarines from the US in the early 2030s before a new fleet of boats is built for delivery from the 2040s.
The three-nation partnership is between the US, Australia, and the UK, and was signed in 2021 under former Liberal prime minister Scott Morrison and the US Biden administration.
The Pentagon will consider whether the pact is in line with US President Donald Trump's "America First" policy.
Defence Minister Richard Marles confirmed the US had advised Australia and the UK of the review.
"We are committed to AUKUS and we look forward to working closely with the US on the review," he said in a statement on Thursday.
"It is natural that the administration would want to examine this major undertaking, including progress and delivery."
Mr Marles pointed to the UK's recently completed AUKUS review, which reaffirmed its support.
"We look forward to continuing our close co-operation with the Trump administration on this historic project," he said.
Critics of AUKUS point to the lagging production of boats in the US, and warn that the deal might jeopardise the American navy's capabilities or undermine Australia's defence sovereignty.
Australia paid the US almost $800 million in February - the first of a number of payments - to help boost its US submarine industrial base.
US Defence Secretary Pete Hegseth told Mr Marles during a meeting in Singapore this month that Australia should lift its defence spending to 3.5 per cent of gross domestic product, or output.
Australia's defence spending is on track to hit around 2.3 per cent of GDP by 2033/34.
Co-Chair of the Friends of Australia Caucus, US Congressman Joe Courtney, on Thursday warned against dumping the AUKUS deal.
"To walk away from all the sunk costs invested by our two closest allies - Australia and the United Kingdom - will have far-reaching ramifications on our trustworthiness on the global stage," he said.
"(It) is a direct contradiction to the administration's 'America First, but not alone' goal of countering aggression from China, Russia, and other adversaries."
Opposition frontbencher Bridget McKenzie said the US review was a "deeply concerning development" ahead of Prime Minister Anthony Albanese's departure for the G7 summit in Canada on Sunday.
Mr Albanese hopes to have a meeting with Mr Trump on the sidelines of the gathering in Alberta.
"Any undermining of this serious and substantial alliance between our two countries should be of grave concern to all of us," Senator McKenzie told Nine's Today show.
Greens defence spokesman David Shoebridge said it was time the government held its own inquiry into the "dud deal".
"We need an independent defence and foreign policy, that does not require us to bend our will and shovel wealth to an increasingly erratic and reckless Trump USA," he said.
