The $240 billion deal with Britain and Australia is in question as the Pentagon has begun to assess the Aukus defense accord to ensure it is in line with Trump’s “America first” approach. The study may make allies increasingly concerned about the trilateral alliance’s ability to fend off China’s military ascent. Specifically, Australia is depending on Aukus to replace all of its submarines.
Australia would purchase nuclear-powered attack submarines under the 2021 Biden-era deal, with the US agreeing to supply up to five Virginia-class ships starting in 2032. In the early 2040s, a new class of combined submarines would be developed.
However, Elbridge Colby, the undersecretary of defense of US and a critic of Aukus, is now allegedly tasked with carrying out that endeavor. Colby stated last year that if war broke out over Taiwan, it would be absurd for the US to have fewer nuclear submarines.
“Aukus is a landmark security and defense partnership with two of our closest allies,”
the British government said in a cautious response to the announcement of the US assessment. It is one of the most strategically significant alliances in decades, fostering economic growth and job creation in communities throughout all three countries while promoting peace and security in the Indo-Pacific and Euro-Atlantic.
“As the UK did last year, it makes sense that a new government would wish to reevaluate how it handles such a significant cooperation. To maximize the advantages and prospects that Aukus offers to our three countries, the UK will keep up its strong collaboration with the US and Australia at all levels.”
Will AUKUS survive the Pentagon’s strategic review?
The deal’s survival now seems to be in jeopardy, despite the fact that it was widely supported by US national security lawmakers and that Australia is attempting to increase its security spending in accordance with Trump’s desires.
The accord does not appear to have been a top priority for the US president. When asked about Aukus during Keir Starmer’s February visit, Trump seemed unsure of the term and said, “What does that mean?”
The evaluation comes after Defence Secretary Pete Hegseth called for Australia to boost military spending from 2% to 3.5% of GDP last week. Only 2.4% has been guaranteed by the nation’s prime minister, Anthony Albanese, who maintains that Australia will choose its own military priorities.
In order to increase American submarine manufacturing, Australia has already paid the US over A$800 million this year, and another A$2 billion is due by the end of the year. The nation pledged to invest A$368 billion ($239 billion) in the initiative over a thirty-year period.
Just hours before the news broke, the British administration vowed a $7.69 billion investment in its nuclear submarine industrial base. With its superior weapons technology and hypersonic missiles, in addition to submarines, Aukus is the most significant military collaboration between the three countries in decades.
