The sprawling $368 billion AUKUS nuclear-powered submarine program, a joint initiative among Australia, the United Kingdom, and the United States, is entering its fifth year amid ongoing debate and challenges. Marking one of Australia’s largest defense projects, the program aims to enhance strategic capabilities through the purchase of US Virginia-class submarines followed by the domestic construction of a new class of nuclear subs, known as SSN-AUKUS, in Adelaide.
Despite significant progress, including multi-billion dollar investments in infrastructure and workforce development at the Osborne shipyard near Adelaide, the program faces vocal opposition. Critics, including former prime ministers Paul Keating and Malcolm Turnbull, as well as former foreign ministers Gareth Evans and Bob Carr, argue that the program is excessively expensive, fraught with deliverability concerns, and potentially undermines Australia’s sovereign decision-making. Some skeptics assert that uncertainties around US willingness to fulfill the submarine sale by 2032, given production bottlenecks and geopolitical risks, pose real threats to the timeline. In addition, questions surround the UK’s capacity to meet its shipbuilding commitments amid current industrial strains, with the British submarine yard tasked with completing existing classes before beginning AUKUS vessels.
Supporters of AUKUS counter these points, pointing to Australia’s substantial financial contributions aimed at increasing US production capacity and commit to the Pentagon’s permanent submarine presence in Western Australia through the Submarine Rotational Force – West. This base is seen as a critical strategic asset and a reciprocal element meant to secure America’s commitment to the program. The Australian government also emphasizes strong diplomatic backing from the new British government, with Prime Minister Andy Burnham reaffirming support and funding for the submarine industrial base despite existing challenges.
On the matter of industrial capacity, proponents note that while British shipyards face tight schedules delivering multiple submarine classes, delays are anticipated rather than outright cancellation, with economies of scale from joint Australian-British production viewed as a strategic advantage. The Australian government is also pursuing the domestic shipbuilding capability as a long-term industrial ambition, investing not only in military capability but also in skills development and job creation projected to reach 30,000 positions.
Critics remain unconvinced by these arguments, contending that an alternative path—such as purchasing additional US Virginia-class submarines or consolidating production solely in the UK—may be more cost-effective and practical. Some express concern that Australia’s strategic autonomy could be compromised through obligations implicit in acquiring nuclear-powered submarines integrated into US and British defense systems. However, defenders of AUKUS reject claims that the arrangement would force Australian involvement in future conflicts, viewing them as unrealistic given Australia’s historical alliances and geographic realities.
Public opinion in Australia currently favors the program, with recent polls indicating nearly 70% support, and bipartisan political consensus appears firm. A formal inquiry into AUKUS, led by former labor minister Peter Garrett, continues to explore criticisms but so far has not shifted public or governmental commitment.
As AUKUS moves from concept to tangible infrastructure, its future will depend on managing industrial challenges and sustaining allied political will amid evolving geopolitical dynamics, particularly concerns about China’s regional ambitions. While uncertainties remain, the project’s scale and investment make it increasingly difficult to halt, positioning AUKUS as a defining feature of Australia’s strategic landscape for decades to come.
