Australia’s AUKUS nuclear submarines could fuel regional arms race despite assurance
Dec 4, 2023
Defence Industry Minister Pat Conroy says Australia is not worsening the arms race and gives assurance about the submarines’ nuclear reactors. The deal could still spark a defence build-up in Asia-Pacific while Australia lacks the facilities to deal with nuclear waste, analysts say.
Australia may have asserted that its acquisition of nuclear-powered submarines under AUKUS is not aggravating the “arms race”, but the deal and the three-nation alliance could still fuel a defence build-up in the Asia-Pacific and heighten regional tensions, security analysts say.
At the national press club in Canberra on Tuesday, Australian Defence Industry Minister Pat Conroy reiterated the importance of the submarines to the country’s defence while debunking “myths” about the trilateral deal struck with Britain and the United States, which is largely seen as a countermeasure targeting China.
“The arms race is the greatest it’s been since 1945, and that is why I reject assertions … that Australia is somehow fuelling that arms race,” he said, adding that rising tensions in the Asia-Pacific had posed the most challenging strategic environment for Australia since World War II. “We are responding to it in a responsible and mature manner, like Australian governments should.”
Australia will own at least eight submarines over the next three decades through the A$368 billion (US$243 billion) deal. First announced in 2021 and finalised earlier this year, the controversial pact has raised concerns in the region.
Collin Koh, a senior fellow at the S. Rajaratnam School of International Studies in Singapore, said Conroy’s comment was not a surprise as countries including China and others in Asia-Pacific often couched their arms acquisitions in “defensive terms”.
Most countries would do so in the name of national security interests but it did not mean such actions ensured peace or safety, he said.
Even before AUKUS was announced in 2021, China and other regional countries had already embarked on significant military build-up since the 1990s, Koh said.
“Conroy may not be necessarily wrong to say AUKUS responds to this already ongoing condition, yet at the same time, it’s also not wrong to say that AUKUS … may not only be used by Beijing to legitimise its naval build-up, it also could be exploited as a justification for other regional countries’ military build-up programmes,” Koh said.
Australia’s acquisition of the submarines might trigger new problems as other countries could argue that they should also acquire similar capabilities, said Maria Rost Rublee, a nuclear politics expert at Monash University.
These countries are not limited to “dangerous actors”, for instance, in South Korea where the majority of its people have expressed a desire for their country to own nuclear weapons, Rublee added.
“Just having this type of technology in the hands of a country where you have strong popular support for nuclear weapons could be an issue,” she said.
In an analysis earlier this month, Ankit Panda, the Stanton Senior Fellow in the Nuclear Policy Programme at the Carnegie Endowment for International Peace, warned the accumulation of weapons such as missiles could potentially lead to unintended attacks.
“The Indo-Pacific region has entered a new missile age … each nation individually seeking deterrence while as a whole steering the region into ever more dangerous waters,” he said. “A particular risk concerns the prospects of attacks on the nuclear forces of countries like North Korea and China, by US or allied forces in ways that may not be intended.”
By the 2030s, the Indo-Pacific region would be “full of thousands of new missiles that can be expected to be used widely in the context of a major regional war”, Panda said.
Responding to Conroy’s comments, the national convenor of Labor Against War in Australia, Marcus Strom, said: “If your answer to growing regional tension is to add offensive weaponry, you create a logic towards war.
“AUKUS is designed to shore up American power in East Asia, not de-escalate tensions,” he added.
While Conroy has given assurances about the safety of sealed nuclear reactors within the submarines, analysts argued that the lack of facilities in Australia for the eventual disposal of these reactors is worrying.
“The strength of this agreement is that the reactor module comes to us sealed. It comes sealed, designed to be never opened over the life of a submarine. You don’t have to refuel it, you don’t have to insert new fuel rods … [over] the life of the submarine,” Conroy said.
But nuclear waste expert Ian Lowe said in an analysis on The Conversation website earlier this year that Australia has failed for decades to find long-term storage solutions for small quantities of low- and intermediate-level nuclear waste.
Even Australia’s allies and AUKUS partners, the US and the UK, do not have long-term solutions for nuclear waste storage, according to Lowe.
“This should be concerning. To manage the waste from our proposed nuclear submarines properly, we’ll have to develop systems and sites which do not currently exist in Australia,” Lowe said.
Australian states such as Victoria, Queensland and South Australia have said they would not accept a nuclear waste facility within their borders.
While it will be another 30 years before Australia has to worry about dumping the submarine’s nuclear reactors, it is not a long time, Rublee said.
“If they take their nuclear stewardship obligations seriously, they must immediately begin working on the long-term storage of high-level nuclear waste,” she added.
