Aukus: US to review submarine pact as part of \America First\ agenda

Australia would buy up to five Virginia-class attack submarines from the US - seen here in Western Australia earlier this year - under the Aukus deal

The US has launched a review of its multi-billion dollar submarine deal with the UK and Australia, saying the security pact must fit its America First agenda.

Under the trilateral pact, widely seen as a response to the growing power of China, Australia is to get its first nuclear-powered subs from the US, before the allies create a new fleet by sharing cutting-edge tech.

Both Australia and the UK - which did its own review last year - have sought to play down news of the US probe, saying it is natural for a new administration to reassess.

The move comes as Australia faces pressure from the White House to lift its military spending, from 2% to 3.5% of GDP, a push so far resisted by Canberra.

The agreement - worth £176bn ($239bn; A$368bn) - was signed in 2021, when all three countries involved had different leaders.

The department is reviewing Aukus as part of ensuring that this initiative of the previous administration is aligned with the Presidents America First agenda, a US defence official told the BBC.

As [US Defense] Secretary [Pete] Hegseth has made clear, this means ensuring the highest readiness of our servicemembers, that allies step up fully to do their part for collective defense, and that the defense industrial base is meeting our needs.

The review will be headed up Elbridge Colby, who has previously been critical of Aukus, in a speech last year questioning why the US would give away this crown jewel asset when we most need it.

Defence Minister Richard Marles, speaking to local Australian media on Thursday morning local time, said he was optimistic the deal would continue.

Im very confident this is going to happen, he told ABC Radio Melbourne.

You just need to look at the map to understand that Australia absolutely needs to have a long-range submarine capability.

Some in Australia have been lobbying for the country to develop a more independent defence strategy, but Marles said it was important to stick to a plan - a reference to the previous governments controversial cancellation of a submarine deal with France in favour of Aukus.

An Australian government spokesperson told the BBC it was natural that the new administration would examine the agreement, adding the UK had also recently finished a review of the security pact between the long-standing allies.

There is clear and consistent support for the deal across the full political spectrum in the US, they said, adding Australia looked forward to continuing our close cooperation with the Trump Administration on this historic project.

A UK defence spokesperson told the BBC it was understandable for a new administration to look at the deal, just as the UK did last year.

Aukus is a landmark security and defence partnership with two of our closest allies, the spokesperson said, and one of the most strategically important partnerships in decades, supporting peace and security in the Indo-Pacific and Euro-Atlantic.
