US congressional report explores option of not delivering any Aukus nuclear submarines to Australia
Report offers alternative of the US navy retaining boats and operating them out of Australian bases
A new United States congressional report openly contemplates not selling any nuclear submarines to Australia – as promised under the Aukus agreement – because America wants to retain control of the submarines for a potential conflict with China over Taiwan.
The report by the US Congressional Research Service, Congress’s policy research arm, posits an alternative “military division of labour” under which the submarines earmarked for sale to Australia are instead retained under US command to be sailed out of Australian bases.
One of the arguments made against the US selling submarines to Australia is that Australia has refused to commit to supporting America in a conflict with China over Taiwan. Boats under US command could be deployed into that conflict.
The report, released on 26 January, cites statements from the Australian defence minister, Richard Marles, and the chief of navy that Australia would make “no promises … that Australia would support the United States” in the event of war with China over Taiwan.
“Selling three to five Virginia-class SSNs [nuclear-powered general-purpose attack submarines] to Australia
would thus convert those SSNs from boats that would be available for use in a US-China crisis or conflict into boats that might not be available for use in a US-China crisis or conflict,” the report argues.
“This could weaken rather than strengthen deterrence and warfighting capability in connection with a US-China crisis or conflict.”
Under the existing Aukus “optimal pathway’, Australia will first buy between three and five Virginia-class nuclear-powered conventionally armed submarines, the first in 2032.
Following that, the first of eight Australian-built Aukus submarines, based on a UK design, is slated to be in the water “in the early 2040s”.
But the Congressional Research report describes
an alternative “military division of labour”, under which the US would not sell any Virginia-class submarines to Australia.
The boats not sold to Australia “would instead be retained in US Navy service and operated out of Australia” alongside US and UK attack submarines already planned to rotate through Australian bases.
The report speculated Australia could use the money saved to invest on other defence capabilities, even using those capabilities as a subordinate force in support of US missions.
“Australia, instead of using funds to purchase, build, operate, and maintain its own SSNs, would instead invest those funds in other military capabilities – such as … long-range anti-ship missiles, drones, loitering munitions, B-21 long-range bombers … or systems for defending Australia against attack … so as to create an Australian capacity for performing other missions, including non-SSN military missions for both Australia and the United States.”
The report also raises cybersecurity concerns, noting that “hackers linked to China” are “highly active” in attempting to penetrate Australian government and contractors’ computers.
It argues that sharing nuclear submarine technology with another country “would increase the attack surface, meaning the number of potential digital and physical entry points that China, Russia, or some other country could attempt to penetrate to gain access to that technology”.
The debate over whether the US should sell boats to Australia is also grounded in
ongoing concern over low rates of shipbuilding in the US: the country’s shipyards are failing to build enough submarines to supply America’s own navy, let alone build boats for Australia.
For the past 15 years, the US Navy has ordered boats at a rate of two a year, but its shipyards have never met that build rate “and since 2022 has been limited to about 1.1 to 1.2 boats per year, resulting in a growing backlog of boats procured but not yet built”.
The US fleet currently has only three-quarters of the submarines it needs (49 boats of a force-level goal of 66). Shipyards need to build Virginia-class submarines at a rate of two a year to meet America’s own needs, and to lift that to 2.33 boats a year in order to be able to supply submarines to Australia.
Legislation passed by the US Congress prohibits the sale of any submarine to Australia if the US needs it for its own fleet. The US commander-in-chief – the president of the day – must certify that America relinquishing a submarine “will not degrade the United States undersea capabilities”.
The report argues that Australia’s strict nuclear non-proliferation laws could also weaken US submarine force projection under the current Aukus plan.
Australian officials have consistently told US counterparts that, in adherence to Australia’s commitments as a non-nuclear weapon state under the Treaty on the Non-Proliferation of Nuclear Weapons, Australia’s attack submarines can only ever be armed with conventional weapons.
“Selling three to five Virginia-class SSNs to Australia would thus convert those SSNs from boats that could in the future be armed with the US nuclear-armed sea-launched cruise missile with an aim of enhancing deterrence,” the report states.
The report – authored by Ronald O’Rourke, an analyst for naval affairs in the Congressional Research Service for more than four decades – also makes the case for retaining the current Aukus arrangement.
It argues that selling Virginia-class boats would send “a strong signal to China of the collective determination of the United States and Australia, along with the UK, to counter China’s military modernisation effort”.
“The fact that the United States has never before sold a complete SSN to another country – not even the UK – would underscore the depth of this determination, and thus the strength of the deterrent signal it would send.”
It was also argued that selling nuclear-powered submarines would accelerate the establishment of an Australian submarine fleet “and thereby present China much sooner with a second allied decision-making centre – along with the United States – for attack submarine operations in the Indo-Pacific.
“This would enhance deterrence of potential Chinese aggression in the Indo-Pacific by complicating Chinese military planning.”
The report says selling Virginia-class boats to Australia would be comparable to assistance the US gave to the UK and France in the 20th century in establishing their nuclear submarine fleets and nuclear weapon arsenals.
Previous Congressional Research Service reports have flagged the possibility of no submarines being available to sell to Australia, but Australia has previously rejected contemplation of any “division of labour” in lieu of acquiring submarines.
The Guardian has approached Australia’s defence minister, Richard Marles, for comment.
