AUKUS ministers settle Australia on three in-service Virginia-class submarines
Singapore meeting streamlines the buy to second-hand boats and launches the first Pillar II undersea-drone project
Summary
At the Aukus Defence Ministers' Meeting in Singapore on 30 May 2026, Australia, the United States and the United Kingdom agreed to streamline Australia's submarine acquisition to three in-service Block IV Virginia-class boats, rather than a mix of new and used, to simplify training and maintenance and cut cost. Deputy PM and Defence Minister Richard Marles met US War Secretary Pete Hegseth and UK Defence Secretary John Healey. They also launched the first AUKUS Pillar II "Signature Project" — undersea-drone (UUV) payloads, with delivery from 2027. Defence Industry Minister Pat Conroy said three in-service boats had been Australia's original preference. The agreement steadies Anthony Albanese's costliest defence program amid US delivery doubts.
By the numbers
- 3 — in-service Virginia-class submarines Australia will buy.
- 30 May 2026 — date of the Singapore ministers' meeting.
- 2027 — first delivery target for the Pillar II UUV payloads.
Why it matters
AUKUS Pillar I is the largest defence undertaking in Australian history and was clouded by US production shortfalls and a Washington review. Settling on in-service boats reduces some risk but deepens reliance on the US fleet and revives the sovereignty debate. The first Pillar II project signals the pact moving beyond submarines into advanced capabilities.
What to watch
- Confirmation of delivery timelines and any US production constraints.
- Cost disclosures and parliamentary scrutiny in Canberra.
- Progress and partners on the Pillar II undersea-drone work.
