Australia’s contribution to AUKUS should be a next generation conventional submarine

Sherlock Holmes teaches us that when all possible explanations have been eliminated, the only remaining answer – no matter how improbable – must be correct.  As prospects are diminishing that Australia will be able to receive a nuclear-powered submarine before the 2050s, policy makers are faced with two choices: do nothing, or fast track something that will add significantly to the undersea warfare capabilities of the three AUKUS partners.

The latest development is that two US Senators – one serving and one just retired – Democratic Chair of the Senate Armed Services Committee Jack Reed and his Republican predecessor Senator James Inhofe, have warned that the US does not have the capacity to build submarines for Australia.  Previously, Australian officials have dismissed any negative commentary about the nuclear submarine plan as “noise”, but this is getting hard to ignore.

Maybe the report by the nuclear-powered submarine task force due in March will prove the critics wrong, but unless it comes up with a concrete schedule with dates, legally enforceable commitments and so on, Australia needs to have a Plan B.  A document that emphasises intentions, good will, more discussions, dialog, harmonising requirements, committees, and further investigations gets us nowhere.

Even the most vocal critics of conventional submarine technology concede that they nevertheless retain some performance advantages, such as in complex, shallow water littoral environments.  They are also comparatively cheaper to build and – depending on their size and complexity – a nation can acquire at least three conventional submarines for every nuclear-powered boat.

A new generation fleet of Australian conventional submarines could see some of them permanently based in Guam – or even Japan – making an important contribution to USN-led coalition operations in areas such as the South China Sea.  Some could also travel to the UK, though what contribution they could make to joint security from there is unclear, but the gesture might be politically worthwhile.

A commitment to actually doing something to help ourselves would also go over well in Washington.  US figures are reportedly surprised and disappointed at the supine position of Australia, which seems to believe a solution for our defence needs will be handed to us on a platter.  Why should Australia expect the US to solve our submarine problems for us?  First and foremost, this a challenge to be met by the sovereign Australian government and not offshore it like some sort of strategic help line.

The quickest solution for Australia would be to forget about the Collins Life of Type Extension due to start in 2026 and fast track the local construction of the South Korean KSS-III Batch 2 design – now owned by Hanwha – which could see boats in the water from 2030.  These are long-range conventional submarines that achieve a very low indiscretion rate by using lithium-ion batteries and other advanced technologies that were never part of the cancelled Attack class program.  Their endurance could be further expanded by building a resupply base on Christmas Island – surrounded by deep water and easy to protect – that would give them an extra 25% time on station.

Another option would be a Next Generation Collins class – a larger version of the Swedish A26 submarine, similar to the one favoured to be chosen by the Netherlands to meet their need for a long-range oceanic submarine.  A Third Generation Collins in the 2050s could be nuclear-powered, with the involvement of both the US and the UK.  That’s called long term planning and is probably closer to the spirit of AUKUS because it would contribute to sovereign capability.

For all the boosters of nuclear-powered submarines, we say this: unless Australia has a highly skilled construction base, we will be condemned to forever seeking to buy them from the US or the UK – and, as we are witnessing, the chances of that ever happening are receding.  As those two nations learned from the Sea Wolf and Astute programs, without a continuous submarine construction program, the loss of skills can be catastrophic.

The only sure way to guarantee that Australia will be able to build nuclear powered submarines – other than the reactors themselves – is to be able to transition from building large, advanced conventional submarines to something with a different propulsion system. Put simply: those arguing that an interim submarine is too inconvenient are condemning to death the idea of the local build of a nuclear-powered boat.  We will need a skilled, experienced, existing workforce, existing program management and existing local supply chains.
