Rolls-Royce Expands for Aussie submarine reactor needs
An AUKUS class submarine

Rolls-Royce has revealed ambitious plans to substantially expand its Raynesway site in Derby, which is expected to generate more than a thousand jobs.

The British engineering giant announced that the expansion is primarily aimed at catering to the increasing demand from the Royal Navy and Royal Australian Navy, as well as to commitments made under the recent AUKUS agreement.

Back in March 2023, “it was confirmed that Rolls-Royce Submarines would provide all the nuclear reactor plants that will power new attack submarines as part of the tri-lateral agreement between Australia, the UK and US”.

This agreement has led to a surge in demand for Rolls-Royce’s services.

The expansion, backed by funding from the Ministry of Defence, will take place on recently acquired land surrounding the existing Raynesway site. Notably, it is expected to “create 1,170 skilled roles within Rolls-Royce across a range of disciplines, including manufacturing and engineering.”

Steve Carlier, President of Rolls-Royce Submarines, expressed his enthusiasm about the development. He said, “This is a truly exciting time for our business, with work secured that will see us support UK and Australian submarines well into the second half of this century. It will see thousands of jobs created across the UK supply chain, many of which here in Derby, and we’re proud to be playing our part in this international endeavour.”

Carlier also highlighted Rolls-Royce’s long-standing relationship with the Royal Navy, stating that they have “provided the power to the Royal Navy’s nuclear submarines for over 60 years”.

11 present UK submarines plus likely at least 1 more for a UK total of 12 plus 8 from Australia is a minimum of at least 20 reactors.

The plan is stated as being 15 UK SSN 4 SSBN and 8 Australian SSN so 27 reactors. Not sure if a 20% uplift in staff will cover that.

Most BAE Submarines staff are design and theyve already submitted a planning request that increases office space by 200, this second application is doubling their fabrication facilities footprint.

There is probably an expectation of economies of scale, given those reactor numbers. Those economies plus technological improvements may mean reactor manufacturing gets a little closer to an assembly line/”mass production” model.

It would be lovely if 15 RN SSN happens but I think 12 is a more likely and, still very good, number.

12 modern subs allows 4 to be in constant use and a surge of 8-9.

I’d be more interested to see how they crews 12 SSN + 5 T32 + all the RFA crew issues that will abound with modern tanker, FSSS and Bays.

Would be really surprised at 15 UK SSN. That’s more than double the present 7Astute SSN. A move to 8 as I expect, or even 10 at the outside would be stretching it. I doubt even RR doubling its reactor production (as planed) can stretch that far.

That is at least 20 PWR3 (I’m betting on 22). And the really important thing is that it all then starts again as I cannot see Australia building it’s own reactors. There are questions yet to be answered. There has to be a decision made about either securing new long term supplies of HEU or developing LEU. Decommissioning and long term disposal / storage of reactors / waste. But here in Derby we are all pretty happy as they aren’t building on the cricket ground 😎.

Morning mate, I can definitely see a minimum of 12 for the RN (4 X SSBN, 8x SSNR) and at least 5 for the RAN, which is pretty good as it stands. Not sure if we are actually going to get many more than 10 new SSNs for the RN and that might be pushing it. The RAN is going to rent/buy at least 3 US Virginia class SMs (likely to be BLK 4 variants), but the latest info remains somewhat unclear as to how long they will have them for. Latest thinking appears to be a requirement to last… Read more »

I believe those Virginias will be replaced by SSNr, with 8 SSNr being bought.
2040s for the first SSNr to enter service in Australia. If 8 are bought it’ll be the late 2050s by the time they are all built.
I think Virginias are an interim buy, of which only one will be new build.

Morning Louis, That was the initial way I read things too, but, it appears that AUS are going to purchase at least 1 direct from the US builders, which adds an interesting dimension to the programme. Are they going to own/operate a 2 boat SSN force or will the contract have a buy back clause? If you are going to splurge upwards of $2 billion on a asset, you aren’t just going to give it back if you can expect some 30 odd years use out of it. Especially if the time frame to get them in service is from… Read more »

Eventually those Virginias will have to be replaced by something if Australia want 8 SSN. If only one is being bought new, assuming it’ll have the longest life remaining, entry into service around 2032 would mean 30 years comes up around 2062. I took the recent news to mean more that maybe the build rate on Aussie SSNR would be slowed. The only option to replace Virginias would be more SSNR or the US SSNX, but given Australia would be building SSNR and already have it in service then it’s surely the only option. Having said that maybe this is… Read more »

The whole article makes sense in part, but somewhat ‘ muddies the waters’ in others. Their aim is to have a fleet of 8 in service by 2050, with the first 3 being USA Virginia’s from about 2035 onwards.
Might just be the RAN building a bit of redundancy into the programme to allow for any unforeseen potential issues with getting SSNR into service. Which would make sense.

‘Around 2032’ is the in service date for the first boat.
From what I’ve heard, the two transferred boats will be Block IV, without the VPM.
5 SSNR in service by 2050 is quite ambitious if the first is to enter service in the early 2040s. Virginias will probably be replaced earlier than expected to keep the production going.

They are buying two second hand Virginias with about 20 of their 35 years life remaining (exact boats to be decided) as well as one new build. They will keep the 3 and progressivley add AUKUS as they come off the assembly line achieving a peak 8 boat fleet in the early 2050’s and then during the following decade three more AUKUS will be acquired replacing retiring Virginias on a 1 for 1 basis until in mid 2060’s they have an 8 boat AUKUS fleet.

Agree that that is the logical path/conclusion,. Unfortunately the article just throws some timing issues up, probably unintended, as buying a new build from 2035 onwards would have it in service until approx 2060 unless they returned it sooner.
Either way, it can only be good news for UK PLC.

Or perhaps Canada could bide it’s time and bid for some ‘slightly used, one/two owner’ SSNs. By the 2040s, collective AUKUS production could become so amped that it becomes a buyer’s market, requiring incentivization of buyers w/ a toaster oven. 😉 Willing to bet slimy ChiComs are worried re collective output in 2040s and beyond. 😁

Canada are certainly a bit of a conundrum where defence is concerned – perhaps having the US as a neighbour allows a certain amount of complacency?
Would agree that given their geographic location and long coastline, joining the Nuc SM club is surely the way ahead? It appears not to currently be the case, as the CAN MOD are looking at replacing their 4 Victoria class SSKs with up to 12 new ones!
Arguably they could probably do with a mix of both SSN/SSK types, failing that then SSNs, but seems not.

Believe your assessment is reasonably accurate. Perhaps a Canadian political perspective is available from a resident? Do you believe Canadians could at least contribute to their own defence w/ the purchase of 12 latest generation SSKs, or will they simply be prey for foreign SSNs? There appears to be a divided opinion re Lt kSSK performance in the the litoral region. Obviously, Canadian SSKs would have no/minimal effect in a SCS scenario, as the Aussies have already realized. 🤔

Unfortunately we don’t seem to have a Canadian perspective, unlike many others both far and wide. 12 new build SSKs would certainly add much to Canadian defence capabilities, as they are highly effective assets, but, they are not really a ‘strike’ capability, and cannot compete with a SSN/GN in terms of range/speed/persistence. It will be very interesting to see what the Canadians ultimately do, as they are probably close to having to decide on replacements now. Given that we are expected to see a reduction in the ‘Arctic’ ice cap due to global warming over the next decade or so,… Read more »

More likely a late Astute to be built, but even that will require a whole new logistic and training tail for just one sub!
I think they ment 2nd hand Blk 3/4 Virginia’s.

My expectation is the two second hand Australia will get will be from among the last couple of Batch 4 as their remaining service life will line up with the Australian dates. The new build will likely be tacking on an order for one more Block 4/Block 5 minus the payload module (I dont believe there is any significant technological difference internally between Block 4 & 5 apart from the addition of flank arrays but these may well be retrofitted to earlier boats anyway). Theres more internal difference between block 3 & 4 mainly centred around construction cost and maintenance… Read more »

That’s what the article states, it also muddies the waters a bit when it states that AUS will have 8 SSNs by 2050 which includes the 3 US SMs!!!! So not exactly certain which way it’s going, but as per post with @WZ, the logical outcome would be to have 8 SSNR class by 2050, with the 3 Virginia’s being returned as the AUSUK SMs get delivered. Think it might be a tight schedule anyway, as I can see the UK taking the first 2-3 SMs, so much will depend on how fast RR can manufacture the RC modules as… Read more »

I read it as 5 SSN(R) + 3 Virginia’s = 8 SSN by 2050. Then the Virginia’s start getting replaced by additional SSN(R). I am assuming 3 year drumbeat for Australia. Now does that mean 8 in commission & ready for service at all times or 7 + one coming online? If the former, then you are talking 9 submarines in service (for a short while) before reducing to 8. It only takes a couple of years either way to make this add up. Even the offer of 2 additional Virginia’s is only if SSN(R) does not appear on schedule.… Read more »

Irs a good a read on the outcome as any other, personally believe that they will build up to the 8, then we shall see if they maintain the numbers at 8 as that would mean another 3 SSNR, as you have posted. After that it’s anyones guess, but believe they will continue to operate manned SMs just like we will. I know some ex RN Submariners who have taken the leap and joined RAN to serve on the Collins class. They stayed out there, so must like it.

Morning Danielle, Yes, seems a tad optimistic to me, particularly as it would mean increasing RN Submariner numbers by approx 40% over its current force to accommodate the new SMs. You would be looking at somewhere in the region of 1200-1400 Submariners across the board to furnish the extra SMs,. It’s not something you get from the local job centre, nor indeed can we just open a new box of them. It would be something we would have to start recruiting and growing in the next year or so to get the right levels of experience for use in the… Read more »

You’ll obviously know more about this than me, but reductions in crew sizes could change that.
Trafalgar to Astute saw crew size change from 130 to 98. Vanguard to Dreadnought only sees a crew size difference of 5 however, so maybe that reflects the fact that a vessel needs a minimum number, and the RN is getting very close to that number.

Differing levels of automation, US boats have minimal automation and require large crews, UK boats have some automation reducing crews (for example UK boats while having two helm stations could be fully steered by single man whereas US boats required at least two helmsman to steer with one station controlling pitch and the other controlling yaw with a central co station that could be manned in combat giving access to assist both stations) whereas the Soviet boats were highly automated with not even a single human stationed in the Torpedo room but it also meant they could do very minimal… Read more »

That reduction in crew size isn’t strictly correct mate. Both Trafalgar and Astute class actually had/have a complement of around 120ish. They only take around 95-100 of those to sea at any given time, and rotate the rest around depending on the deployment. Most of the excess crew are engineering types (ME and WE) with a smattering of Logies and Warfare types. It’s called a ‘5th Watch system’ and is used to support maintenance requirements etc. SSBNs operate in a similar fashion, despite 3 boats having 2 crews, and being slightly larger. A reduction of 5 in the overall crew… Read more »

Your assessment of RAN purchase is apparently correct, per Australian ministers. Acquisition of a minimum of three, potentially as many as five, AUKUS SSN class, depending upon rollout schedule. Aussies intend to retain Virginia class boats.

It still reads a bit odd to me! However, as time progresses, perhaps the ‘muddy waters’ will become more transparent!
According to the article, Surf-West is due to become operational by 2027, with upto 4 Virginia’s and an Astute based there. Looks increasingly likely that the UK boat will be a permanent position with family also out there-thats new! Will be a much sort after posting if true.

Umm…according to a recent Guardian (Australian edition) article, senior Australian ministers have clarified the government’s commitment to purchase at least three, and potentially five, boats of the AUKUS SSN class. The Australians intend to retain the Virginia class SSNs acquired during the 2030s. Presumably, you are correct in that this purchase of AUKUS SSNs would presage continuing orders for the following class, but the official response was that that decision would be left to a future government. Still a solid double, to use a baseball analogy, but not quite a home run. Sorry to be the bearer of good, but… Read more »

Excellent. Let’s hope Aukus continues to provide a qualitative edge over the opposition and the RN genuinely does get 12 SSNs. The powerplant needs to come in on budget , no delays and ideally be PWR3 same as Dreadnought class SSBNs. 24 reactors is a decent undertaking. 4 for SSBNs, 12 RN Aukus, 8 RAN Aukus. Who knows maybe Canada will come online and order Aukus as well. They will need a replacement for their Victoria class subs ex upholder class in the same timeframe.

Furthermore, would suggest that we should be encouraging Canada to join AUKUS as a five eyes nation. They have had even more difficulty in keeping their Upholders operational than the RAN with the Collins Class. Both have suffered severe manpower shortages. I read that the Dreadnought class will be the first RN subs to be designed with female accommodation.

Allegedly the US has in the past leaned on Canada not to purchase nuclear submarines as they dont want to share the same underwater submarine routes on the approaches to North America that they use for deep high speed runs shaking any possible pursuit when leaving port. Essentially they worry if Canada acquires them the local waters will become congested and risk collisions.

The first 2 Virginia’s are expected to have something like 20 year lifespan left when acquired. So if they arrive 2032 they start going by 2052. RAN will still be building SSN(R) by 2052 based on a 3 year drumbeat. RAN is hoping for 5 SSN(R) by 2050 (plus 3 Virginia’s). Will Virginia number 3 be new (30 years) or 2nd hand (20 years)? A few changes in government in all 3 countries by then. ASC could even be building SSN(R) for RN by 2060. Most of those commenting now won’t be around to find out!

(Had to search to find a relevant article for this comment.) Highly recommend reading an article in the June 20, 2023 edition of the Japan Times re AUKUS.

Among other points article stated one AUKUS participant currently devotes ONE PERCENT of defense budget to simply complying w/ provisions of ITAR! Unfreakin’ believable!
