Not sure if I've posted this before, but I figure I'd best mention it as a looming project. The first unit will be laid down in Q1/1931, with the last unit of 4 laying down a year later.

It is not conceived as a battleline unit, but rather as a ship in the mould of pre-war Armoured Cruisers, to be able to act as a flagship unit in secondary theatres and to operate with aircraft carriers. It is intended to engage Class A cruisers in wartime, with protection against guns in the 8" range.

An alternate design concept with six 12" guns was explored, but it was felt that this would be too prone to being risked in the battleline, whilst also being marginal for gunlaying.

1940 Cruiser Projects

The 40mm battery is, perhaps, a little large for the period, but that's partially a consequence of the octuple mounting.

Armor is sufficient to deal with the intended adversary, giving the ship protection at ranges where it's weapons can hurt it's intended foes.

These ships could be built in a short length of time compared to the major capital ship units the RN requires in order to secure it's trade routes.

They might be ok now, but they are going to be little more than glorified cruisers in a capital ship short RN in 4 years time.

I'd also question whether 185 rounds per gun are necessary, unless the idea is to be able to patrol and fight well away from resupply. Certainly the historical ships that carried guns of this size did not carry this many rounds.

Myself, I'd be a little concerned about the stability: 1.07 is, to me, a little bit low. I've been trying to keep stability at 1.10 or higher. But that might be just me.

Another comment on the design: with 110,000 SHP, you'll probably want 3-4 shafts, 55,000 on each shaft is probably a bit much.

Stupid boy, Pike! That wasn't meant to happen - it's supposed to be a 4-shaft plant.

That's the envisaged role, but probably overkill. I basically enlarged the magazines to use excess strength.

The historical ships, though, were also from an era when ships carried fewer rounds all told than in the 1930s.

Concur, stability could be better; a reworded design is on the cards, so I'll look to enhance it.

Yes but we know that now using hindsight, in the 30's however its still a "big gun" mentality.

I'm have mixed feelings about these "armored cruisers", they surely can outmatch CA's but are more expensive and don't have as much punch as BC's.

I tend to sit on Hrolfs side of the fence on this one...

I agree though, the BC seems low and in addition I think the bulges are not really nessasary.

I can only second what others already said. She´s too larger and weak for her role, too weak as a capital unit, in fact a waste of limited hull numbers for cappital ships, the UL needs modern BBs in a world full ot 35-40kts warships that can have a QE for lunch, the bc of the ship seems relatively low, the range probably a little bit excessive and the number of main gun shells quite high.

If you want to hunt CAs you need more speed and/or more armor. Otherwise your design might loose a duel against a better armored, well-balanced 13kts treaty CA.

Is it a capital ship? Not really, it is, like

If they did operate together they could quite likely take on 1 of these ships and sink her with the loss of one ship and another limping home to be repaired.

That being said if a navy has the resources to build these ships its an awefully tempting project.

on much less tonnage. Here's something I have in mind for a bit later, and they'll certainly get built if the Treaty collapses:

I can see it as a waste of hulls in the limited by treaty sense, but without that restriction, or for a power that wants to invest in the as least materially cheaper vessels for hulls, why not build large cruisers and heavy armored cruisers?

Its not like we'll have anyone fighting another Jutland or anything....right?
