TKMS Type 212CD (Victoria class replacement megathread)

[Underway]

I had that discussion last night - I pointed out that the only reason our budget rose in the recent past was because the orange dude called everyone out, and when things don't look so orange outside, there will be far less impetus to appease, and far less money thrown at looking to solve problems.

Someone mentioned being concerned about whether or not we get 15 RCDs....I don't know if we've ordered any of the long-lead items yet beyond the first 3. (Gearboxes/etc)

That will be a real indicator in my opinion.

I learned today its highly likely that we order the next 6 RCD long lead items very soon. I think it was early Jan but can't remember the exact time. It do remember thinking "wow, that's soon".

I was just being pessimistic sadly.
There is just such a long long track record of us buying the absolute bare minimum in just about everything we do. I badly want us to break/destroy this old mantra.
I love the AOPS’s and was lucky enough to tour HMCS MB last year Oct while she was in Windsor, as I was, over Thanksgiving. I think they are wonderful ships. Again was I just being pessimistic on what the Politicians would do to her the others if funding got cut back. Transfer her over the the CCG and strike 6 of the new med icebreakers from the buy side of things.

I’m glad to hear that the ‘buy side’ of things on the Rivers has moved a bit beyond the initial 3. Hopefully this expands and broadens out quite extensively.

Its fair. Evidence will be in the future, however, the US will never go back to where it was. There is a chance the Reps regain the Whitehouse with a different cast of players and be more subtle and smarter in pushing our buttons. The Dems aren't getting rid of tarriffs, they might change them somewhat but they are here to stay in some form. Things have permanently changed since the post cold war order.

As much as I think we look too previous Canadian defence spending and not be confident our own current spending won't continue there is something else that we are forgeting.

Since confederation Canada as a whole harbours a deep dislike and distrust of the US. Can't be too American or you lose elections (see Harper). And that my friends is why defence will be top of mind to the government for well after this current administration is gone. Because the US has shown they can switch their minds on a dime.

Wasn't it the Germans who said "We will never f**king trust you again." at at defence conference in Halifax?

We struggled to keep 4 in various operational states and it gutted the surface fleet funding to even do that, even 8 will be a huge challenge requiring a lot of infra for training, repairs and another 1000 odd techs, engineers and other support people ashore. The nice part is if we just buy them more or less unchanged (maybe use 60 hz internal power vice 50 hz) then we can leverage the German and Norwegian navies for pooled engineering resources on the supportability and upgrade side.

I know nothing of the industry but am surprised that they wouldn't use high frequency AC like large commercial aircraft (generally 400Hz) to save space and weight.

Thanks. I had not heard of this before (my being 1/2 way around the world my feeble excuse). I went looking but given Chatham Rules in place for the occasion when such was purportedly stated, not much can be found.

I note this the agenda for that 2025 International security conference: https://halifaxtheforum.org/wp-content/uploads/2025/11/Agenda2025.pdf

I speculate (speculate is the operative word) that it was this 22-Nov-2025 dinner session:

Just Another Country: America Surrenders its Moral Authority, with two speakers:
- Mr. Mark Hetfield, President, HIAS, United States;
- Mr. Ali Nazary, Head of Foreign Relations, National Resistance Front of Afghanistan, Afghanistan;
... and the moderator (host) Ms. Heather Hurlburt, Associate Fellow, Chatham House, United States.

I note Matt Gurney posts on the noted comment about 'trust' here : Matt Gurney: 'We will never fucking trust you again'

I also don't see British CDS Sir Tony Radakin on the participant list on the Internet, but frankly that list is quite possibly very inaccurate.

US mid-terms are over. Democrats obtained a majority in House & Senate, but not a 2/3 majority in both (where 2/3 majority needed to legally ignore a POTUS veto). So if POTUS vetoes Congress, the Congress can in reply reign in the US executive branch by withholding funds - possibly causing a government shutdown if there is major disagreement. That is a very extreme measure, and will that cause a USA policy change? I am skeptical.

Anyway, back to Victoria class - I don't see much of a change in US policy in the next 2 years (despite mid-term results) , but next presidential election with results in just over 2 years time, could see a US administration whose more benign policies , could lead to the Canadian Government in reconsidering how many Canadian Patrol Submarines to order - and I fear the Canadian Government could reduce the order.

My hope is at least 12 are ordered , in order to provide sovereignty presence in the Arctic, in addition to the Atlantic and Pacific. I don't want to restart the Arctic discussion here , but I still believe sustained Canadian Patrol Submarine presence in the Arctic is NOT POSSIBLE unless a way is found to replenish, while in the Arctic, the AIP reactants of such a submarine.

My hope is the procurement of 12 proceeds. There are massive challenges ahead there for the RCN.

Noah's recent commentary on the Murray Brewster story on the 8+4 sub story is worth a read. He's saying that in essence Canadian industry was specifically lead to believe and plan that 12 subs would be coming. He's saying that although the stated policy was 'up to 12 subs', that our industry was specifically encouraged to base their plans/funding/timelines off of 12 subs being purchased. He also says that its more than likely that if the overall number was going to be 8 all along that a number of them would NOT have gotten involved in the contract at all and that some might even consider walking away from the project if only 8 subs was the final number.....

I'm not able to post the links to his story at the moment.

If this is true, it's a pretty disastrous and short sighted turn of events. A substantial part of the pitch for this submarine program was the associated industry support, workshare and offsets which would help stomach the high unit costs. By doing this, you are jeopardizing the aforementioned advantages and potentially rising the unit/program cost by introducing uncertainty into the procurement itself.

It also makes the Government look incredibly untrustworthy, they'd done so much work to repair our very poor reputation on procurement and this is flushing it all down the toilet again.

A terrible omen of what is to come if true and a generational fumble.

I'm wondering if the story that Mr Brewster was told is along the same lines of the one that came out in the May/June timeline saying that we were looking at splitting the sub contract between both Hanwha and TKMS, ordering 6 of each......a story that we fairly quickly squashed.

Can't say it would surprise me. Carney is, after all, a liberal. You won't see a pipeline in the near future either.

I think we're going to see a bunch of stuff start to fall back... And the debt announced today will be eye watering.

 

[GR66]

I know there is lots of justified cynicism on these forums, but should we automatically assume that the plan for 8 x subs up front and an option for another 4 means we will only get the original 8? How were the NSS contracts worded with regard to ordering the River-Class for example? Our F-35 order sounds like it was always going to be in batches, etc.

Honestly I think that's nonsense; the annual spend on maintenance will be in the hundreds of millions of dollars, and just 4 subs was enough to get a lot of industry to spool up some particular capabilities required for the Vics. 12 is obviously more, but there won't be a shortage of work with 8 or a break even point at 10 subs.

Plus if it's a common design with common equipment there will be opportunities to pick up work on the German and Norwegian subs (and vice versa) if our companies have capacity when their domestic companies are full.

Over the lifetime we'll spend 10s of billions on R&O, so it's still a huge amount of work.

Won't having 8 subs, presumably 4 one each coast kinda ruin the maintenance/deployment cycle? Also hard to believe that the government will move ahead with a maintenance facility on coast if they are also looking at cutting the order. Do we honestly believe that the Germans and Norwegians will be looking to farm out work all the way in Canada? I would imagine they would prefer to keep that kinda work at home.

Companies don't care about deployment, they care about maintenance cycles. There will always be some on each coast in the dock, plus alongside work.

Given recent article and speculation on RCN potential Type-212CD batches (if the TKMS contract is negotiated and signed), it makes me wonder if the Type-212CD may have differences between batches? I note the Type-212A had some differences between batches.

I found this recent video on the older Type-212A submarine of interest:

In particular I noted it claimed the initial Type-212A had some issues that had to be fixed - So I surfed a bit to see what changed in the Type-212A, and frankly, I did not find as much detail as I had hoped to find (All my information is from unclassified sources so there could be some speculation/error in the below) :

I read that the Type-212A’s air-independent propulsion (AIP) system relies on nine Siemens BZM 34 (34 kW) Proton Exchange Membrane (PEM) fuel-cell modules operating in parallel, using liquid oxygen and metal hydride hydrogen storage. Operating nine separate modules within a compact hull requires an intricate array of reactant supply lines, coolant circuits, and nitrogen purging valves. This fundamental nine-module BZM 34 architecture was retained across both German and Italian production batches of the Type-212A. I don’t know to what extent the type-212CD will have the same in regards to number of modules.

The Type-212A incorporated a non-magnetic austenitic steel hull, an X-shaped stern rudder configuration for shallow-water operations, integrated flank array sonars, and a water-ram torpedo expulsion system. Internal machinery—including the single MTU diesel generator—was installed on double-resilient raft-mounted platforms to minimize structural noise transmission to passive sensors.

The Type-212A being the first series-produced submarine class equipped with a fuel-cell AIP system, early operational deployments of the Type-212A likely involved an initial learning curve in managing marine fuel-cell logistics and auxiliary balance-of-plant maintenance. I think it is reasonable to infer that ongoing refinement of operational protocols and servicing routines helped establish the system's reliability, supporting confidence in long-term deployment across both of the German and Italian navies.

The German Batch 2 Type-212A boats (U35, U36) differed from Batch 1 (U31–U34) in several respects. Overall length increased from 56.0 m to 57.2 m, with both the sail structure and pressure hull reported longer; German Wikipedia attributes this to new equipment in the sail without specifying which item. To me, that is a big change. The enlarged sail houses a four-person combat-diver lockout chamber. An optronic mast replaced one of the two periscopes. The enlarged sail was also fitted for (but not with) the Callisto B communications system, a hoistable mast and towed buoy intended to allow communication when submerged; the German Federal Audit Office reports that the Bundeswehr ended the Callisto programme in June 2022 after 19 years of development without a usable result. The boats also received an updated combat system and integrated sonar, with Link 11/16 data-link capability.

Type-212CD:

Building on the operational evolution of the 212A—which Batch 1 displaced ~1,524 tonnes surfaced and ~1,830 tonnes submerged—the Type-212CD (Common Design) represents a structural expansion, displacing ~2,500 tonnes surfaced and a reported ~2,800 tonnes submerged. The 212CD features a distinctive diamond-shaped outer casing designed to reduce active sonar returns. The machinery plant shifts from the 212A's single MTU 396-series diesel to twin MTU 4000-series diesel generators, lithium-ion batteries (originally lead-acid on the Type-212A), and 4th-generation PEM fuel cells in the Type-212CD. For context, while the Type-212A 3rd-generation BZM 34 operated at a fixed 34 kW per module, Siemens’ 4th-generation BZM modules elevate individual output to a higher 40–60 kW while slashing module weight from over 600 kg down to about 200 kg—tripling power density and enabling scalable plant grids between 320 kW and 480 kW within a compact footprint. Traditional optical periscopes in Type-212A are eliminated in favor of non-hull-penetrating digital sensor and communications masts in Type-212CD, featuring an optronic photonics suite supplied by Hensoldt alongside integrated communications masts from L3Harris.

Again the above is from unclassified sources - so it may be inexact.

But it does have me pondering/speculating, that if RCN goes with batch procurement (and does not stop procurement after one batch) what might be the various differences in batches?

It would be disappointing if the original number was only 8 boats all along.

One very speculative concept of mine, is that by going with 8 in the first batch, the Canadian government still has some leverage for Industrial offsets - but, ... but at the same time, by keeping alive the possibility for another 4 in the second batch, it helps give the RCN some leverage over the Canadian Patrol Submarine supplier, so for the supplier to be more motivated to best possible keep to cost, schedule and performance in the first 8 (as those aspects will be important before the RCN orders the final 4).

Of course I am trying very hard to be optimistic in that speculation.

I would like to see 12 or even more than 12 ultimately ordered.
