Some of the official language that the Australian authorities have used to describe the AUKUS program acknowledges that the resultant submarine will share a significant number of common systems with the Virginia class.

Don't think anyone will know for sure without some level of insider knowledge, at least for a while, but from the verbiage, there is a possibility that the AUKUS submarine will be a "distant cousin," "Australianized version," or otherwise (arguably) a derivative of a late block of the Virginia class considering all the common systems that they will share.

I may have made an "analytical leap" concerning the relationship between the AUKUS and Virginia classes or appeared to have, so in case anyone is wondering . . .

The Virginia class is the only class of SSNs that will be in production in the US when the AUKUS commences production come ~2030, as

, assuming it is not further delayed.

The Navy’s FY2024 budget submission envisaged procuring the first SSN(X) in FY2035. The Navy’s FY2025 budget submission defers the envisaged procurement of the first SSN(X) from FY2035 to FY2040. The Navy’s FY2025 30-year (FY2035-FY2054) shipbuilding plan states: “The delay of SSN(X) construction start from the mid-2030s to the early 2040s presents a significant challenge to the submarine design industrial base associated with the extended gap between the Columbia class and SSN(X) design programs, which the Navy will manage.”

Inevitably, this means the Virginia class will be the most likely, if not the only plausible principle source of American SSN technologies that will be incorporated into the AUKUS program.

In fact, the RN's Dreadnought class SSBNs, which are now under construction, will each be powered by a single

powering the Virginia class.

Just as the Dreadnought class' predecessor, the Vanguard class shares the PWR2 nuclear reactor with the the AUKUS class' predecessor, the Astute class, there's been a reasonable amount of

that the AUKUS class will also be powered by the PWR3 nuclear reactor powering its generational SSBN counterpart.

Meanwhile, any UK design for the SSN-AUKUS is likely to utilise the Pressured Water Reactor 3 (PWR3) system, which is being developed for use in the Royal Navy’s future Dreadnought-class nuclear-powered ballistic missile submarines. Developed by Rolls-Royce in the UK, the PWR3 is an evolution of the PWR2 used on the in-service Astute-class SSNs.

Obviously sharing the same powerplant doesn't make one submarine a derivative of another, but if two submarine classes also got other systems like their VLS and combat system in common, then an argument can probably be made, especially should the combat system that is to be integrated necessitate employment of a common set of principle sensors.

Though what

perhaps even more interesting, assuming it is indeed accurate.

Even if the AUKUS acquisition plan succeeds, it will deliver a questionable capability. The submarines’ designs would be a mix of two blocks of Virginia-class submarines, more than 14 years apart in design, and yet-to-be-designed SSN-AUKUS using Britain’s yet-to-be-tested PWR3 reactor. Moreover, SSN-AUKUS would be partly built by the underperforming British submarine enterprise that’s under great pressure to deliver the Royal Navy’s next class of ballistic missile submarines.

If that's indeed accurate, then the only way for the AUKUS submarine to make any reasonable logistical and operational sense for a navy the size of Australia's, or perhaps for it to even be delivered on time, is if it is to be effectively based on the Virginia class.

Granted, the military isn't a place where everything always makes sense . . .

When AUKUS subs in operation (note: different timeframe than when they receive them) in late 2030 or early 2040s, China will have many 095 & 096 and 093B/C , and likely 097 as well .. so, really wasting money for Australia and won't make any difference, hopefully my country NZ would choose different approach to engage China then confrontation, which NZ has been doing anyway

Obviously AUKUS has been poorly implemented but a capable submarine fleet, and navy more generally, should be a priority for Australia regardless of our posture to China and isn't a waste of money. Is it prudent to be completely helpless as we are currently? No, no it is not.

It's not crazy that our best frenemies Indonesia are on a trajectory to overmatch Australian capabilities within two decades (cost effectively buying off the shelf from Europe vs freakishly expensive novel designs, with local manufacturing requirements, that never gets built anyway). Why would they put up with our shit when they can push us around?

It is capable now on paper but whether still capable in 2040s? who knows

I don't know about you but to me spending US$368B is wasting money and to do what?

With that money, China could easily built 200 SSN Type 095 and China is currently has ~11x nominal GDP as Australia and about 20x as PPP

And not clear whether AUKUS SSN Aussie version would be more capable than 095, but definitely 2x 095 will be more capable than any AUKUS sub version with much cheaper cost (2x 095 cost is much less than 1x AUKUS subs). Thats the way it is as China is much more productive and much bigger economy of scale, much more resources to produce things cheaper and efficient with good quality. China could make many things 5-10x cheaper for comparable quality, especially ships than the US, let alone Aussie

There is a chance that Indonesia may purchase some 093B/C from China (even second hand) (a lot lot cheaper) when Aussie has received AUKUS sub in late 30s

So to me the best approach for Aussie is not to confront China and make China as an enemy, because China is not the enemy and Aussie really rely and depend on Chinese market, without China, can you imagine what Aussie quality of life would be ? The best approach is to engage with China like what NZ do

Historically China and India are not expansionist, unlike European colonist .. even true when China and India were the biggest economies in the world from year zero to 1800

I don't see why China would want to "invade" Australia ..... what is the logic ? Indonesia has more reason to "invade" Australia than China (I know it won't be in the near to medium future)

That is $368 billion AUD (Australian Dollars) for the AUKUS submarines. Not USD (US Dollars). $232 billion USD. It is still quite a lot though.
It is mind boggling how much those submarines are supposed to cost. You can buy a Yasen-M SSN for like a billion.

Aside from a few old white guys there's no one in Australia pushing to militarily "confront" China, especially now that the US is abdicating, but a defense strategy of intentional helplessness (which is functionally the strategy now) is a terrible move. India and China aren't expansionist now but behaviour from hundreds of years ago is a terrible guide to future behaviour in a world of increasing conflict and environmental decline. No one is talking about invasion but the future is simply unknowable.

Doesn't have to be AUKUS, it just has to be something.

Maybe you should start by stop poking China and stay at your corner of the world.

At ~10,000 tons in displacement, the Hunter class is practically the size of a Cold War era CG.

The CEAFAR2 can't possibly require that much room, so guessing the Hunter class is intended for extended patrols far from Australian shores, especially if it's only armed with a 32 cell VLS?

All the indications are that the program was simply
Please, Log in or Register to view URLs content!
from the beginning, with the pitfalls of an immature design exacerbated by the mandated domestic CEAFAR2 radar as the "tail wagging the dog", leading to considerable unanticipated weight growth and corresponding reduction in performance.

Before the review that recommended truncating the program from 9 ships to 6 was released, there were rumours that it was going to be cut off at the three ships that are presently under detailed construction contracts. Indeed, one suspects that the major reason why a second batch of three Hunter-class frigates has been notionally retained at this juncture is to hold out the prospect of maintaining continuous shipbuilding in Adelaide (or rather, to avoid the political implications of being seen to abandon it) with the Batch 2 Hunters notionally bridging to a future Hobart-class successor (while Perth builds the Tier 2 frigates).

Some years ago now, Australia was struck by the same revelation that struck the UK regarding the need to maintain a continuous naval shipbuilding sector in order to maintain the associated workforce and therefore to avoid the massive start-up costs associated with reconstituting skills atrophied in the interim between major construction programs. Of course, implementing that continuous naval shipbuilding strategy is considerably more challenging for a nation of Australia's size than it is for the UK, and is made more challenging by (a) now splitting the work across two yards some 2500km apart and (b) importing the first three Tier 2 frigates directly from abroad in order to alleviate a self-induced schedule crunch.

Don't think anyone will know for sure without some level of insider knowledge, at least for a while, but from the verbiage, there is a possibility that the AUKUS submarine will be a "distant cousin," "Australianized version," or otherwise (arguably) a derivative of a late block of the Virginia class considering all the common systems that they will share.

I don't think there is any intention for SSN-AUKUS to be a "Virginia by stealth", however it is certainly the case that the incremental, pragmatic response to delays will be to shift further in the direction of the Americans (from the "very beleaguered" to the merely "beleaguered"). To the extent that there is a gap between rhetoric and what appears practical, that is more plausibly accounted for by the politically-infused dreamland that birthed and sustains the entire enterprise, rather than some unseen 4-D chess move.

Back in December 2023 I put forward my own prediction as to how all this is likely to unfold, and I don't see any reason to revise it at this stage:

(1) Australia's acquisition of two second-hand Virginia-class submarines is pushed back or cancelled owing to a combination of lack of enthusiasm in Washington to transfer them and our lack of readiness to receive and operate them.
(2) The AUKUS nuclear submarine program is ultimately thrown in the bin and a new conventional program is pursued with local shipbuilding.
(3) A limited number of Virginia-class submarines (say, four) are eventually acquired from the American production line at ruinous expense and maintained at low readiness, partly to make the Americans happy and partly just to say that we did it.

Recent developments furthering this skeptical view include a recent Congressional Research Service

that publicly floats the idea that, instead of transferring SSNs to Australia, maybe USN could just operate SSNs from Australia on Australia's behalf instead:

Under a U.S.-Australia military division of labor for performing SSN missions and non-SSN missions the forward rotations of U.S. and UK SSNs to Australia planned under Pillar 1— SRF-West—would still be implemented; up to eight additional Virginia-class SSNs would be built, and instead of three to five of them being sold to Australia, these additional boats would instead be retained in U.S. Navy service and operated out of Australia along with the five U.S. and UK SSNs that are already planned to be operated out of Australia under Pillar 1 as SRF-West; and 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, for example, long-range anti-ship missiles, drones, loitering munitions, B-21 long-range bombers, or other long-range strike aircraft—so as to create an Australian capacity for performing non-SSN military missions for both Australia and the United States.

Needless to say, any such pathway would be ruinous for maintaining even the barest pretense that Australia is still a sovereign nation.

There is also the British government's own Infrastructure and Projects Authority which has

the nation's ability to produce naval nuclear reactors to meet requirements (i.e. Dreadnought and SSN-AUKUS) as "unachievable" for three years running now (p. 15 & p. 43).
