Second-hand subs, first-class bill

Australia was meant to get a mix of new and used Virginia-class submarines. Now the starter pack is three in-service boats from the US Navy. Simpler, apparently. Still very bloody expensive.

Yeh Nah Goods blog cover titled Second-hand Subs, First-class Bill, about AUKUS buying second-hand submarines.

Australia has found a new way to make a $370 billion defence deal feel like a Facebook Marketplace pickup.

The AUKUS submarine plan has been “streamlined”. Lovely word, that. Means different things depending on whether you are the bloke writing the press release or the poor bastard reading the invoice.

The new plan is simple enough: Australia is now set to buy three in-service Virginia-class submarines from the United States, instead of the earlier mix of new and used boats (Defence Ministers). ABC reported the original pathway had Australia expecting at least two used Virginia-class submarines and one new model, but the revised plan shifts to three second-hand boats and no new one (ABC).

So yes. Second-hand subs. First-class bill.

The official story

The official AUKUS statement says the new approach will “streamline” Australia’s Virginia-class submarine acquisition by “simplifying supply chain management, operational and maintenance requirements, and maximising cost efficiencies” (Defence Ministers).

Defence Minister Richard Marles told reporters the shift puts a “premium on simplicity”, because Australia would otherwise face the possibility of operating nearly four different submarine classes at once (ABC).

There is a real point in there. Running fewer variants is easier than running a Frankenstein fleet of old Collins boats, multiple Virginia variants, and the future SSN-AUKUS class that is still meant to turn up in the 2040s (ABC).

Fine.

But it is also very Australian to order a once-in-a-century defence capability, wait through years of speeches about sovereignty, then be told the starter pack has been simplified into used US Navy stock.

No new boat. No showroom smell. No little ribbon on the periscope.

Just three in-service submarines and a very serious man saying it is all part of the plan.

The bill did not exactly disappear

This is where the “cost-effective” line needs a bit of a hose down.

Marles has said the shift will deliver significant savings, but he also acknowledged it will not fundamentally change the overall cost situation (ABC). The Guardian reported the long-term AUKUS agreement is projected to exceed $370 billion, with Marles saying the change is a valuable financial contribution to the program but is mainly about simplicity (The Guardian).

So the slogan is doing a lot of work.

Cost-effective compared to what? A new boat, maybe. The whole thing, not so much.

Australia is still looking at up to AUD 8 billion at HMAS Stirling for infrastructure and logistics support, AUD 3.9 billion in initial down payments for the new submarine construction yard in South Australia, and AUD 12 billion for the Henderson Defence Precinct (Defence Ministers).

That is before we get to the decades-long cost cloud over the broader program.

If someone sells you a second-hand Hilux and says the bargain is that the garage extension only costs twelve billion dollars, you are allowed to ask a follow-up question.

The delivery question

The used-sub twist also does not remove the bigger AUKUS headache: can the US actually hand over the boats?

ABC reported expert concern that there is no assurance the United States will consent to sell the submarines, given the challenge of American shipyards lifting production enough to supply both the US Navy and Australia (ABC).

The Guardian reported the US is trying to increase Virginia-class submarine production, with the target for AUKUS delivery far above the current production rate described in the article (The Guardian).

That matters because the first Virginia-class submarine is not expected until the early 2030s, and Australia is already extending the life of its 30-year-old Collins-class submarines by another decade as a bridge (The Guardian).

So the pathway goes something like this:

Keep the old Collins boats going.

Hope the US has spare used Virginias.

Pay into infrastructure here.

Help build capacity there.

Wait for SSN-AUKUS in the 2040s.

Call the whole thing simpler.

Yeh nah.

Second-hand is not automatically stupid

Here is the caveat before someone from Defence gets excited.

Second-hand does not always mean bad. In-service boats can still be serious capability. Having three of the same type may make training and maintenance easier. If the choice is one new boat plus two used variants versus three used boats of the same configuration, there may be operational logic in that.

That is not the issue.

The issue is the gap between the sales pitch and the receipt.

This was sold to Australians as an historic sovereign capability leap. The official language still says AUKUS Pillar I remains on track to support Australia’s acquisition of a conventionally-armed, nuclear-powered submarine capability (Defence Ministers).

But the public is now being told the near-term acquisition has changed from a mix including a new boat to three in-service boats from the US Navy.

That is a material vibe shift.

If the new plan is better, explain it like adults. If the new plan is cheaper, show the numbers. If the new plan reflects what the US is actually willing or able to provide, say that too.

Do not wrap a downgrade in showroom language and call it streamlining.

The YNG read

There is a pattern here.

Big national project.

Massive bill.

Sovereignty talk.

Decades-long timeline.

Then the details arrive slowly, and somehow the plain-English version gets worse.

We are not getting the simple thing people thought they heard. We are getting the version that comes with qualifiers, caveats, transition phases, support arrangements, and a very expensive shed out the back.

Maybe AUKUS ends up being the right call. Maybe the strategic case is real. Maybe the used boats are the cleanest bridge to a future Australian fleet.

But if the public is paying first-class money, the public is allowed to notice when the first delivery is second-hand.

That is not being anti-defence.

That is having a receipt.

Second-hand subs.

First-class bill.

Standard issue bullshit.
