On December 5, 2025, the U.S. Department of Defense confirmed the ongoing AUKUS submarine program, endorsing plans to transfer a minimum of three Virginia-class attack submarines to Australia starting in the early 2030s and to launch the first domestically built Australian submarine in the early 2040s.

On December 5, 2025, the Pentagon confirmed the continuation of the AUKUS nuclear submarine partnership with Australia and the United Kingdom, endorsing the planned transfer of at least three Virginia-class submarines to Australia from the early 2030s and the construction of the first Australian-built SSN-AUKUS submarine in the early 2040s. The review validates the existing pathway while noting areas where timelines, industrial capacity, and governance arrangements require further coordination among the three partners.
The assessment assures Canberra that U.S. support remains firm for the Virginia-class transfers and the broader transition toward the jointly developed SSN-AUKUS class. Australian officials described the review as confirmation of enduring backing for the program, while leaving room to adjust delivery schedules and performance targets over the coming decades. The review also examined industrial capacity, noting that U.S. submarine yards currently cannot meet national demand alone, underscoring the need for expanded production to sustain AUKUS.
Defence Industry Minister Pat Conroy outlined Australia’s plans to reorganize its defence bureaucracy from July 2026 to better support the program, merging key acquisition, sustainment, and naval shipbuilding groups into a Defence Delivery Agency reporting directly to ministers. This restructuring is intended to facilitate management of the A$368 billion ($240 billion) program over the next 30 years, which includes purchasing at least three Virginia-class submarines, with options for two additional boats, and constructing the new SSN-AUKUS class using British hull designs and trilateral technology. The SSN-AUKUS boats, displacing approximately 10,000 tonnes, will replace the aging Collins-class fleet and provide extended range, endurance, and advanced strike capabilities across the Indo-Pacific.
A second pillar of the AUKUS initiative encompasses advanced undersea and high-tech capabilities, including hypersonic and counter-hypersonic weapons, undersea robotics, quantum systems, artificial intelligence, cyber and electronic warfare, and enhanced information sharing.
Since 2023, U.S. submarines have increased operational presence in Australia, with UK submarines expected to participate from 2026 as part of Submarine Rotational Force West at HMAS Stirling, which could begin in 2027. The rotational presence will include one British Astute-class submarine and up to four U.S. Virginia-class submarines, giving Australian personnel operational and technical experience in anticipation of the first locally built submarine in the early 2040s. Construction of SSN-AUKUS submarines will begin in Osborne, South Australia, by the end of this decade, while the British Navy’s SSN-AUKUS boats will be built at Barrow-in-Furness in the late 2020s.
The AUKUS program will drive substantial industrial growth, with Osborne shipyard expansions projected to generate around 4,000 direct jobs and approximately 20,000 total positions across the three partner nations over 30 years. Australian industry will supply critical components such as hull steel, valves, pumps, batteries, switchboards, and additive-manufactured parts, while workforce development will be supported through training in allied shipyards, naval nuclear schools, and domestic engineering programs.
Australia has confirmed it will not pursue nuclear weapons, enrich uranium, or reprocess spent fuel. The U.S. and UK will supply complete, welded PWR reactor units that do not require refuelling and cannot be accessed without disabling the submarines. Arrangements with the International Atomic Energy Agency (IAEA) will ensure verification of non-diversion of nuclear material while safeguarding classified design information. Australia will also manage all radioactive waste from both Virginia-class and SSN-AUKUS submarines in compliance with domestic and international regulations. These safeguards are integral to enabling Australia’s nuclear-powered submarine capability while preventing proliferation risks for other non-nuclear states.
This review solidifies AUKUS as a long-term, trilateral strategic program, combining industrial, operational, and technological elements to ensure Australia gains a sovereign, nuclear-powered submarine capability while maintaining alliance interoperability and regional deterrence.
