Since our last update...

Canada is in the middle of completing 4 Ontario class Cruisers and 20 Orca class Fleet Boats for 1941 and early 1942.

Discussion is currently ongoing amongst the admiralty as to what the next budget priorities should be.

Top contenders;

1) Disposal or conversion of the Hawkins class cruisers. The last round of discussions had proposed an elaborate CVL/Amphibious assault conversion for the hulls;


However, with the ships now in reserve at Esquimalt, there is concern as to whether the hulls will take the conversion with any lasting effect. Another, less ambitious proposal has been floated which would gear the ships more towards Amphibious support, with a much cheaper conversion;

Effingham class, Canadian [Ex-British] Heavy Cruiser laid down 1916

5) HMCS Hermes is long overdue for disposal or overhaul. Consensus amongst Construction and Repair is that there is no way to sufficiently modernize Hermes to match fleet speeds, nor significantly increase her airgroup. That being said, Hermes does perform a valuable role as a training ship. Her fate continues to be uncertain.


So...What should the RCN's next priority project(s) be?

1. I always liked this idea, but I think the hulls are getting a bit old. Plus, unless you're eyeballing Vinland, I don't see that Canada needs much amphibious capability.

2. Carrier's probably useful, but I'd look at it as replacing one of your three old conversions rather than complementing them.

I am not feeling the amphib part; totally incompatible roles until troop-carrying helicopters are practical.

3. Twelve hulls to replace eight? Give them another 500 t so they can have a belt height that is worth the effort.

4. Probably not good value for money if you can only haul 125 troops.

5. A refit to training functions would be useful.

Canada's somewhat reluctant to just write off large hulls, but there isn't all that much I can do with them. And the RCN has come to a conclusion that it'd rather have some amphibious capacity it doesn't 'need' than find itself in a position of needing it, and not having any. Hence the multitude of "Hey, put landing craft on this useless thing" proposals at the moment. Some are more viable than others, obviously.

The carriers are rather "new" to the RCN; C&G were thoroughly modernized in 1937, Furious in late 1940.

It's a side effect of the design being ordered as replacement to the Hawkins conversions, which were intended to be multirole. The Amphibious capacity may be deleted from the design, along with some tonnage savings.

4 Argylls, and 3 Dianas. They're smaller and less well armed as the Argylls, but superior to the Dianas in all respects. All 12 will likely not be built at once, but in two batches of six, or 3 batches of 4.

Unfortunately, there's nothing in the rules regarding converting boiler space to barracks, as was done with historical APD conversions, and there just isn't a lot of weight to play with, unless I reengine the class...which Canada views as cost-prohibitive for the results.

She's already doing the training, just without a dedicated refit. The original plan was to rotate one of the Hawkins conversions for training duty and retire Hermes, but without those conversions, there's no other ship to cover that role.

I'm really liking the APD conversion of the Hawkins. I might just grab them back from you if you decide to get rid of them.

I understand the reluctance to junk large hulls, but you're not getting much amphibious capability for what you will be spending. New purpose-built LSIs would probably be more cost-effective.

Well, I guess my recommendations would be:

-Refit Hermes.

-A batch of patrol cruisers

-Junk the old cruisers. That's around 80,000 t, I'd guess, with 12,000 t of scrap coming out, plus savings of 20,000 t or more you're not putting into refits. You can build up a heck of an amphib force, and probably start that new carrier, with the output.

I am in general agreement with Rocky that Canada would be far better off disposing of the Hawkins and the Agrylls through scrapping or sale, and using the tonnage thus made available to construct a stronger cruiser force. I do not like the proposed design of the Capital class however: its hull strength is far too weak to stand the storms of the North Atlantic or the North Pacific – the probable areas of employment for such vessels. I would recommend that Canada prepare a somewhat larger and stronger design.

As for amphibious shipping, I would suggest that Canada move in a dual-track fashion: using converted merchant hulls for infantry landing ships (which can be done quickly in war-time) and constructing a number of specialized landing ships for vehicles. I’ve taken the liberty of proposing such a design below for your consideration.

- Longitudinal: 4.25
- Overall: 1.67
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Additional hull stength represents strengthening for beaching operations

Miscellaneous weight represents cargo carried - up to 300 tons of tanks and vehicles, 300 tons of supplies or 150 troops over short distances.

Light displacement 973 tons, less one half miscellaneous weight (300 tons) = 823 tons cost to construct


- LSTs are built to special rules because of them being a mix of a freighter and a warship
- The miscellaneous weight of LST is halved into deductible and non-deductible (50/50)
- The deductible weight is taken off the ships light displacement and so building time and building costs
- Otherwise all normal building rules apply
- For scrapping LST only the reduced weight is used for calculation.
- Any landing craft carried aboard the LST shall be purchased separately under light craft rules

I must admit the cruiser conversion sounds like a juicy reuse of an existing hull, but I'm pondering the numbers and I think Bruce and Rocky might be right. Nothing can beat a purpose-built landing ship. A design like Bruce proposed would be significantly better than an old converted cruiser.

Given Canada's stormy-weather ocean margins, I am mulling whether or not a Canadian version of the British Glen class landing ship dock might be a good choice. It could carry the lighter landing craft, tanks, infantry, etc - and one ship could carry more of that than four converted heavy cruisers. It might be something to consider.

Improved light-weight Automated Dual-Purpose twin 5.5" guns simmed as 1940 Automatics.

5200 tons for 72 planes
100 tons for spare planes and parts
100 tons for CIC facilities and other flagship amenities.
100 tons for Radar and other equipment
525 tons for Miscellaneous fleet stores.
25 tons for UNREP gear
40 tons for additional weight of DP automatic mounts (10 tons per)
35 tons for Miscellaneous Amenities and Superior this-and-that.

All in all I think that the revised Tenacious design is very well balanced; a pair of them would be quite a formidable combination.

I agree, it seems to be a pretty reasonable and well-balanced design. As said in IRC, I'd thin the main belt a bit in order to reinforce the deck armour, but that's as much my personal preference as anything else.

Some designs I was fiddling with last night, no graphics put together yet.

Reused 7.5" gun from Hawkins class (34 tons savings)

There is always the temptation to have landing ships perform their own fire support - unfortunately, it does not work well in practice.

I think the 7.5-in guns ought to be dropped from both designs and replaced with either large caliber AA or DP guns for defending the ship, not trying to get troops ashore.

The Vimy Ridge seems a very expensive response to your situation - though lack of graphic and breakdown of the misc weight makes that difficult. Is this some form of dock landing ship of a straight forward APA? If the latter, a mercantile conversion is far better value for money. Also, no subsidiary landing craft are indicated; how do the troops get ashore?

The Passchendaele look rather like some of the wartime Canadian LST(3) ships that also had recip steam engines. If you're building them in peace time, I think a far better approach would be to go with diesels.

On the Vimy Ridge class, this is a bit of a concern to me:

50 tons for additional weight of DP automatic mounts (10 tons per)

Vimy Ridge has a Well deck and landing craft, I just haven't broken down the misc weights.

Passchendaele is based heavily on Canadian built LSTs, yes. I've been told in the past that Canada wouldn't have a big diesel industry, for some reason. So far all Canada has with diesels are small craft, and the Icebreakers.

I have several points of concern with the revised design of the Capital class.

While they are stable, they are poor sea-boats and not very steady as a gun platform; this would seem to me to negate their role as AA vessels.

Second, they would have serious issues in a heavy seaway with their relatively weak hull. A primary characteristic of a cruiser is its ability to stay at sea in all weather - and I would have doubt that these would be able to do so.

Third - I think the design carries too much topweight. Why are the 57mm guns on raised mounts as opposed to being on the deck? In the drawing there seems to be sufficient deck space for them.

Fourth - Given the ROF of the 5.5in DP, are you allowing enough shells per gun? While 250 might suffice for surface combat, AA defense would eat up ammunition far faster.

1) Forgot to adjust the trim from the earlier version. Doing so regains proper seakeeping.

2) The Gentlemen's rules allows for .9 hull strength on fast combatants under 6000t standard. With the additional thousand tons, I've upped that to .95, which I feel is sufficient for a second-class cruiser.

3) Having the 57mm mounts raised or not doesn't affect the stats. I could lower them to the deck and resite the torpedoes, but I also haven't put any boats on the graphic yet, either.

4) Artifact from the baseline I was using for the original design, have adjusted to 350 rounds.

Awesome drawing !!!

The small scale of the drawing makes it difficult for me to interpret, but it does not seem to match all the details of the Springsharp previously posted.

That called for two single 7.5-inch guns on the centerline, plus four 57mm - there's one gun in the drawing that could be a 7.5-inch, though that is carried so high and the restricted arcs ake me wonder - but I don't see the second one. Have you revised the Springsharp?
