Buy advanced non-nuclear submarines

New maritime strike aircraft

New land-based anti-ship missiles

It’s over…
In the last US election American voters have made it clear they reject the liberal democratic values we hold dear.
Donald Trump’s picks for his new team reinforce this message, as do his threats against Gaza, Panama, Canada and Denmark.
J.D. Vance’s address at the Munich Security Conference show NATO is effectively dead.
Australia keeps throwing money at AUKUS but the Virginia submarines are not going to be available. We need to carefully decouple our defence from the USA.
We have no “shared values” now!
The authoritarian world order
Liberal democracy is now in full retreat, authoritarian rulers have most of the power and the weapons.
USA | Russia | PRC | India | DPRK |
![]() | ![]() | ![]() | ![]() | ![]() |
5700 | 5600 | 500 | 170 | 50 |
Australia is in a weak position with:
- One operational submarine
- An outnumbered and outclassed surface fleet
- A small short-range air force
Australia needs another defence plan.
A new defence posture
The “Forward Defence” strategy is no longer feasible for Australia given we could now be acting alone against major nuclear armed superpower states.
Australia should pivot to the “Echidna Strategy” as proposed by Sam Roggeveen.
Such a defence posture is all that Australia can afford and avoids direct conflict with nuclear superpowers as far as possible.
What we need
- Many small, survivable assets that we own to deter attacks on Australia.
What we don’t need
- A few large, vulnerable, expensive assets to deploy to northern hemisphere wars.
- Assets that can be easily “turned off” by MAGA republicans on a whim.
What we can’t do anyway
- Defend “sea lanes” from multiple nuclear-armed superpower adversaries and their huge navies.
Don’t buy old Virginia Class submarines
We should not be sending nuclear submarines to threaten the PRC. ➧ Australia has no nuclear weapons ➧ The USA is not a reliable ally ➧ The PRC has 500+ nuclear weapons. ➧ We have eight cities. |
There are many reasons not to proceed with this project:
- The US shipyards are not on-track to provide enough submarines for the US Navy, so will not have any spare for us.
- We can’t wait any longer for new submarines.
- These old submarines cost many times more than new non-nuclear submarines.
- It is too dangerous for Australia to directly confront the PRC.
- The USA could withdraw support at any stage over issues like abortion, healthcare, the PBS, the GST, press freedom or LGBTQIA+ rights.
- We could come under extreme pressure to repatriate political refugees back to the USA for prosecution and support the annexation of Palestine.
- This could drag Australia into wars with the PRC, Islamic countries, Panama, Denmark & Canada.
- Decommissioning costs will be very high.
- Large submarines are likely to be detectable near China and in shallower water.
Consider advanced non-nuclear submarines
A wide range of advanced non-nuclear submarines can provide excellent asymmetric defence within 4,000 km of Australia if distributed to ports around the country.
About SIX non-nuclear boats can be bought for the price of ONE Virginia class submarine. Non-nuclear boats are much cheaper to operate.
Non-nuclear boats | Manufacturer | Built | Submerged endurance |
---|---|---|---|
Scorpène | Naval Group / Navantia | 11 | 3 weeks if FC2G fuel cells used (diesel & O2). |
Scorpène Evolved | Naval Group / Navantia | 0 | 12+ days with lithium-ion batteries. |
Type 212A | HDW / SpA | 10 | 3 weeks with PEM fuel cells. |
Blekinge A26 | Saab | 0 | 3 weeks with Stirling AIP. |
Sōryū / Taigei | Mitsubishi / Kawasaki | 7 | 4 weeks with Li-S batteries. |
KS-III | Hanwha / Hyundai | 3 | 3+ weeks with Li-S batteries. VLS option. |
S-80 | Navantia | 1 | 3+ weeks with bioethanol-powered fuel cells |
Endurance comparison
- Nuclear: ~80 days (before food runs out) – no need to surface.
- Non-nuclear: ~80 days (before food runs out) – need to snorkel once or twice for ~30 minutes.
Cost comparison
- Old Virginia nuclear submarine: $US 4,500 million (Australian Naval Institute).
- New Taigei non-nuclear submarine: $US 800 million (The Random Japan).
Given that the cost of new non-nuclear submarines is below the cost of the refurbishment of the rusty old Collins Class submarines, I suggest abandoning the high-risk Collins LOTE project. This is particularly the case if the LOTE does not include replacing the lead-acid batteries with something more advanced.
Weapons comparison
- Old Block IV Virginia nuclear submarine: 65 missiles and torpedoes.
- New Taigei non-nuclear submarine: 30 missiles and torpedoes on each boat = 5 x 30 = 150 missiles and torpedoes for the same money.
Stealth comparison
New non-nuclear boats are more stealthy than the larger SSN when submerged.
SSN can operate at over 20 knots for long periods – but that creates a large large bow shock wave which is a bad idea.
Japanese Sōryū & Taigei submarines
“Japan’s new Taigei class … provide the Japan Maritime Self-Defense Force with some of the most advanced underwater performance of any submarine force in the world.” (US Naval Institute)
Seven Japanese submarines have been built with Lithium-Sulphur batteries to date with each one taking 2.5 years to complete. Lithium-Sulphur batteries appear to be less complex to operate and support than fuel-cell systems.
Theoretically multiple boats could be assembled in parallel in various electorates around Australia.
I suggest RAN exercises with Japan to test Hobart Class vs. the new Taigei Class. (Remember that Tony Abbott wanted to buy Sōryū submarines in 2015.)

Extended Sōryū / Taigei

Duplicating the crew accommodation section in the above diagram would seem to increase the battery capacity by 25%. As well as improving morale and crew retention submerged range should be increased to well over a month at minimal cost.
AUKUS submarines
The UK Labour Party will have the same issues trying to work with the new USA as we will. They may examine Anglo-French collaboration on nuclear submarines if Anglo-USA collaboration becomes infeasible.
Note also that if nuclear submarines were ever built here superpower adversaries would need to destroy them before they could be launched – which would create a major problem if they were fuelled at the time.
French nuclear submarines
Peter Briggs, president of the Submarine Institute of Australia, has suggested buying the French Suffren Class nuclear submarines instead of the AUKUS SSN. These would probably be very capable but unfortunately take 15 years to complete compared to 2 years for the Taigei and cost 3 to 4 times as much.
Cut back on vulnerable surface combatants
In an asymmetric fight with huge navies, Australia’s few surface combatants cannot survive. We will never match the missile and shipbuilding capability of the superpowers.
Existing vessels should be sold or painted white and transferred to Border Force. (See references)
We should certainly not be buying any more frigates, they would be quickly destroyed in any conflict with a superpower. They will either be small with limited defensive magazines or large and a bigger target.

See also new DF-100 missile range.
Join the Global Combat Air Programme
The GCAP is a collaboration between the UK, Japan & Italy to develop a modern long-range fighter. They are looking for more partners.
Aircraft hidden in multiple bases around Australia can provide a more survivable deterrent to hostile superpowers than slow moving frigates with limited magazines.
Australia will need long-range stealth aircraft to penetrate the defences of hostile fleets.
The GCAP Tempest is being designed to fulfil this role. Australia should join the project now to ensure Australia’s range and payload requirements are accommodated and to see if parts can be manufactured in some Australian electorates.
The first flight of the Tempest demonstrator is expected to take place by the end of 2027.
I note that the US 6th generation fighter program (NGAD) is now in doubt – even if these aircraft would be available for Australia to purchase.
Distribute and hide
Instead of concentrating important assets at a few easily-destroyed bases the ADF should distribute and hide assets around Australia.
As far as possible defence assets should be hidden from pervasive satellite surveillance when inactive.

Five eyes?
Given the USA will now align more with Russia (judging by Trump’s cabinet picks) and Russia is aligned with China and the DPRK it would seem that the Five Eyes intelligence sharing arrangement is less viable. The Islamophobic attitude of Trump’s team will be a problem with the whole Islamic world including Indonesia.
Australia should move to establish closer intelligence sharing arrangements with the other remaining liberal democracies and our ASEAN neighbours.
Other assets
Buying non-nuclear submarines saves money that can be spent expanding existing programs and some new ones:
- Ghost bat
- Ghost shark
- Land-based anti-ship missiles
- Smart sea mines
- Tiltrotor troop transports such as Bell V-280 with twice the speed and range of helicopters – if we can build them here.
A Liberal Democratic Alliance?

If Trump pulls the USA out of NATO as previously suggested, some of the remaining democracies (green) might try to form a new Democratic Alliance.
If so, Australia should probably try and join.
This alliance might feature:
- No claim on the territories of superpower nations or Islamic states.
- NATO-like security guarantees.
- EU-like reciprocal health and other benefits for Alliance citizens.
- EU-like free trade and economic cooperation.
- Schengen-like travel arrangements for Alliance citizens.
- An Alliance passport.
As of late December Trump is now reportedly pushing for NATO members to spend 5% of GDP on defence but may settle for 3.5%. This may be his condition for continuing to support Ukraine.
