AUKUS submarine delays and Australia’s nuclear submarine acquisition risks
Consensus Summary
Australia’s AUKUS submarine program faces significant delays and financial challenges as the US struggles to meet production targets for Virginia-class submarines. Both sources agree the US currently builds only 1.1–1.2 boats per year, far below the required 2.0 for its own needs and the additional 2.33 needed to supply Australia. The US Navy’s 30-year shipbuilding plan excludes AUKUS, and workforce shortages, supplier bottlenecks, and prioritization of other submarine classes (like the Columbia-class) are exacerbating delays. Australia has committed billions to boost US and UK submarine industries, but concerns persist about a capability gap if the Collins-class submarines cannot be extended or if Virginia-class deliveries are further delayed. While Defence Minister Richard Marles remains confident in US delivery timelines, experts like Dr Marcus Hellyer warn production may not meet targets until 2035 or later. The US Congressional Research Service has even proposed an alternative where submarines remain under US command but operate from Australian bases, raising questions about operational control in a crisis. Both articles emphasize the high stakes of these delays, with Australia potentially facing a submarine-free period amid rising tensions in the Indo-Pacific.

Key details reported by multiple sources:
- Australia has committed A$2.76bn (US$2bn) to the US and A$863m (£469m) to the UK to boost submarine-building industrial bases under AUKUS.
- The US Navy currently builds Virginia-class submarines at a rate of 1.1–1.2 boats per year, below the required 2.0 for its own needs.
- The US Navy’s 30-year shipbuilding plan excludes AUKUS submarines from its projections, mentioning it only once as a footnote.
- Australia’s Collins-class submarines are undergoing an $11bn ‘life of type’ extension to remain operational into the 2040s.
- Australia expects to receive its first Virginia-class submarine from the US in 2032, with up to five possible under AUKUS.
- The US Navy’s chief of naval operations, Admiral Daryl Caudle, stated in May 2026 that Virginia-class production would reach two boats per year by 2032.
- The US Congressional Research Service has considered an ‘alternative division of labour’ where Virginia-class submarines remain under US command but operate from Australian bases.
- Australia’s AUKUS submarine program is estimated to cost $368bn by 2055.
- The US shipbuilding industry faces workforce shortages, with up to 70% of critical component suppliers having no competitors.
- The US Navy currently has 49 Virginia-class submarines, needing 66 to meet its fleet requirements.
Points of Difference
Details reported by only one source:
- The US Navy’s shipbuilding plan was released in May 2026 and explicitly excludes AUKUS from its projections.
- The Congressional Research Service’s January 2026 report argued that US-commanded submarines operating from Australian bases could be deployed faster in a crisis with China over Taiwan.
- Acting Secretary of the Navy Hung Cao stated that submarines under US or Australian command would be ‘interchangeable’ to the enemy.
- The US Navy initially forecast reaching a Virginia-class production rate of two boats per year by 2026, then revised it to 2028, and now to 2032.
- The US Navy’s shipbuilding challenges include a 10-year build time for Virginia-class submarines, up from six years in the 2000s.
- Defence Minister Richard Marles stated in May 2026 that he is ‘not alarmed’ by US shipyard delays and remains confident the required production rate will be met.
- Dr Marcus Hellyer of Strategic Research Australia argued the US may not meet the required production rate until 2035 or later.
- The US builds Virginia-class submarines at Huntington Ingalls Industries (Newport News) and General Dynamics Electric Boat (Groton).
- The US Navy’s Columbia-class submarine program is prioritized over Virginia-class production, contributing to delays.
- Australia’s Collins-class submarines’ life extension plan was revised to exclude diesel engine replacements.
Contradictions
Conflicting information between sources:
- The Guardian reports the US Navy’s Virginia-class production rate is currently 1.1–1.2 boats per year, while ABC states the rate is ‘between 1.1 and 1.2’ but does not explicitly confirm the lower bound as a current rate.
- The Guardian cites Admiral Caudle’s 2032 target for reaching two Virginia-class boats per year, while ABC’s Dr Marcus Hellyer suggests this may not happen until 2035 or later.
- The Guardian notes the US Navy’s shipbuilding plan excludes AUKUS entirely, while ABC does not explicitly contradict this but focuses more on production challenges rather than the plan’s content.
- The Guardian highlights that the US Navy has 49 Virginia-class submarines and needs 66, while ABC does not provide this specific fleet number but discusses broader production gaps.
- The Guardian mentions a $400m increase in Australia’s AUKUS budget over three years, bringing total resourcing to $2.13bn by mid-2029, while ABC does not reference this specific budget figure.
