1940 RCN Projects

Several 1939 projects have been pushed back by 12-18 months due to budgeting issues arising from the Serapis class, and other issues, but a more firm schedule has been worked out for 1940, going into 1941;

A further 20 S class destroyers have been obtained from the Royal Navy, and will be converted to the same design as the previous 28 members of the class, which will all be redesignated as Sloops, and operated in four ship squadrons with shifted emphasis from fleet escort (Though they may be employed as such when needed until more Tribals are completed) towards a focus on ASW and Trade protection.

A further 8 Tribal (Batch III) class Fleet Destroyers have been laid down in Janurary, and expected to complete this year. The previous 8-gun design has been rejected by the Admiralty in favor of a 6-gun design, with revised layout and greatly increased range.

The Serapis class Frigates will complete early in 1940, after delays and a minor scandal.

HMCS Furious, transferred last year from the Royal Navy, was intended to be refitted immediately, but a combination of budget concerns, and the crisis in Southeast Asia delayed her dockyard availability, with the planned Modernization slightly revised and scheduled for her return from the Far East

The Admiralty has also concluded that the Hawkins class cruisers (Including the newly arrived Cavendish from Australia) are all past due for some manner of modernization, and tentatively scheduled to be sent to the dockyards in late 1940. The exact details of their refits are still being debated. (I have an idea of what to do with them, but feel free to suggest and discuss amongst yourselves)

Rebuild with 8x140mm guns in duple turrets fore and aft. Lots more superstructure and 4 octuple pom-poms amidships on the beam.

Sunday, October 3rd 2010, 10:39pm

I already have 4 Labradors, which are smaller but have half-again as much armament (Argument that those ships are overloaded is preemptively acknowledged). I also continue to adhere to the arguments given a couple years ago that they (Hawkins and Chesters) would not accept new barbettes, which my current 140mm weapons are mounted on. Reverting to manual-loaded twins is possible, but by now experience with operationg the four Argylls (with 5 such turrets) would reccomend against any future manual loaders as a main battery (Single DP mounts have been developed for use on Auxilliaries, and to replace the SP guns on Furious).

I will also have 24 5.5" armed Fleet Destroyers (Tribals, I, II, & III) by the end of the year, which seems sufficient dispersal of the weapon for fleet support roles.

Fast amphibious transport?

An austere APD (Or APCR in this case, I suppose) style conversion doesn't seem cost efficient. Destroyer-Transports came about due to a combination of war-necessity, and availability of numerous hulls (first obsolete flush-deckers, later purpose-modified DEs). There's only five of these ships, and such a limited focus doesn't seem to warrant the costs involved, especially when it would be more efficient to convert a merchant hull or purpose-build in peacetime.

You're close to the track I've been considering, however.

Monday, October 4th 2010, 9:31pm

The Hawkins cannot be rebuilt for turrets, I'm sure we've batted that idea about many times on this board and other sites. It's a shame because with the right guns they could be decent powerful ships. 7.5in singles would be good but an auto/ semi-auto mount would be next to impossible to fit without serious recon work.

Maybe AA cruisers would be best, they are large, have ample room for bulky electronics (radar) and should be stable platforms.

Turn their relatively large hulls into AVs ? It should be possible to place a hangar on their deck and with two catapults they might fit that role. The questions is: Does Canada need AVs?

I don't really percieve a need for seaplane tenders for the RCN, really, though it could be folded into the desgin I've been considering.


A run down on some of the various designs I've toyed with over the years;

All designs are bulged, come in around 10k tons light, and around 32 knots/8k nm, without changes to belt or deck armour.

The CA Design would mount 4 twin 7.5" weapons in Omaha-style gunhouses (No barbette, simmed as mount & hoist), with 6x2 4" DP secondaries

CLAA would mount 20 5.5" DP, in manual-loaded gunhouses (again, no barbette or automation)

CRH is a more conservative iteration of the more prefferred design (below), which would construct a hangar and barracks aft, while retaining the forward pair of 7.5" guns.

CVP is the latest and more favored proposal at the moment, which would see the ships razéed to the main deck, with a large space forward and midships, suitable for use as a hangar or barracks space, and heavy davits aft for Landing craft. Intended as a flexible, multipurpose ship, with capacity for a 12 plane fighter or fighter/bomber flight group, or an amphibious role with reduced flight group (fighter/bombers, or helicopters as they become available). The forward 7.5" gun is retained since extending the hangar that far forward is not considered feasible, and the retained weapon would be useful for either shore bombardment or anti-raider blasting.

I think the latter is the way to go. Have you tried japanese style funnels? The current layout might cause some severe turbulences over her flightdeck.

Seems like it's missing something, to me. And I don't think there's any precedent for a western navy using that kind of rig.

shortened western stacks

It might look weird, but it looks a LOT safer than those huge stacks on a narrow flight deck! Your pilots may thank you. They look more like US CVE's now

I think it looks really cool with the Japanese style funnel. You could always try a Langley style setup though.

Most likely because it does not really fit with the image of how it should look that is subconsciously lumbering in your mind. An image that does not include that large empty space behind the island. :)

Perhaps the addition of a second one and at its heighest point slightly raised above the flight deck might help (or not).
