I was unaware of that layout, since it was not noted. Had I known the layout, I would not have pointed it out. 4" is still light for a Heavy Cruiser IMHO, but I can understand the desire to thicken the deck armor.

The DNC has been speculating about a new class of fast battleships to perhaps follow the Admirals. The basic design details of armament and armour largely follow the basis of the Admiral but one turret has been sacrificed.

It's a Rosbif Iowa!

At first glance they do have quite the similarity to the Iowa's, 9 16in, 33 knots, they are armoured better than the Iowa's were (though that is a Wesworld trait).

If the RN wants to spend 53,000 tons on ships that realistically don't give that much of an edge over say a South Dakota sized ship it is welcome to do so. You could fit a heavy cruiser in the displacement disparity between the two ships, and really I would rather a 27 knot South Dakota and a 13,000 ton CA than one of these.

But that's just me.

As Brock mentioned in his design thread me, Brock and Bruce had a discussion on battleship design on IRC. This is my rough idea of such a cheap and supposdely expendable battleship using the old turrets from the QE class. In addition to be being cheap its also designed to fit into a Type 3 dock. I'm still thinking of ways to trim the weight further. The armour is pretty much at minimum standard being all or nothing. I could pare the ammo down to 100 rpg for the 15in but I don't want to go too low and risk running low on ammo.

I'm not saying I'll actually build these, even in 44, but when the Queens run out of the life something like this is certain. I have toyed with a 6x 15in version which would allow me to build eight such ships if I used Hood's turrets too. Such a vessel works out at around 28,000 tons light.

Well I think the terms "cheap and expendable" can be used with some lightness here, no battleship is really all that "cheap or expendable" but the one you posted, and the ones Brock posted certainly are more so than some others.

Vanguardising doesn't make much sense so far as sim terms are concerned. But IC I could see the Admiralty saying to the Treasury "well we could build 4 more of them big honkin' Admiral Class or we could build a couple of these". I am sure the treasury would be all over that with one caveat; didn't the QE's and Hood get refits not that long ago?

I do like the design though (but I am biased, I liked Vanguard the best out of all the OTL British battlewagons).

I'm amused that post-Cleito, battleship growth trends appear to be heading both up and down...

Well "expendable" is a relative term. What I mean is more of a battleship that the brass feel they can use rather than waiting for the decisive engagement that may never come...

I've made a few tinkering mods. Note that this ship is lighter than even the Victorious, Saint Vincent and Lion forebears. I've tried a range of alternatives (2x3 16.5in, 3x2 15in, 4x2 15in pared down to the bone with 13in belt 700 ft long, 4x3 12in with hypothetical 12in gun, 4x4 12in with same gun but none of those really hit the spot and a smaller and cheaper 30,000 ton version of this ship sacrifices a lot. Realistically perhaps retaining the QEs until the 50s is a better option?

I'm not a huge fan of vanguarding, particularly under our build rules; shaving a month off a 4 year build time is kind of uninspiring.

I know your not a fan of vanguarding Ping, and I agree that OOC it makes little sense to do so based on the rules we have in place.

IC though, I can see a compelling arguement for nations that have substantial older warships or older warship weapons to go before their Parliment/Congress/Assembly/Whatever and say, we feel we need newer battleships to replace the older ones we have, and we come before you with three options: One in money terms is the most expensive but will net us an extremely powerful warship we won't see till after the next electoral period, and may be outclassed shortly after being completed. The second option is to scrap some of our older warships and use as much of the material in their as possible for a new ship that while not the best in the world is still respectable in its own right. The third option is to build a new battleship but one that isn't ridiculously expensive, and yet still has a reasonable chance against a HUBB.

However, in the case of the RN I don't think scrapping the QE's is the way to go, the investment you've put into them in the late 30's means that your going before Parliment and saying "remember those ships we rebuilt in 1936? Now 8 years later we want to scrap them and build new ones." I can't see that going over well. That would be like me going and scrapping the Big Six and putting their main armament on new builds. (Now using the 14in triples they had on something.......)

Another kick-about idea. Going slightly smaller and using 12in guns. This is a British Alaska-type concept of a super-CA killer that can also serve as a capital ship in its own right in certain circumstances and is equal to many older BBs across the world.

Deck Armour: Main deck 4in with a 0.5in splinter deck below joining to the bottom of the main belt
Torpedo Bulkheads: triple bottom, quadruple side bulkhead system air/ fuel/ air/ fuel with backing bulkheads of 0.5in/ 1in/ 0.5in and 0.5in

Block co-efficients on those last two designs are pretty low for capital ships.

Hey! I am the keeper of the sacred block coefficient! ;o)

But you are right, of course.

Looks like Rocky came back to steal your title.

Yeah I've often looked at that.
I could see a version with triple 12in and 4.5in DP mounts instead of the 4.7in being quite useful.

I've made a few changes, increased the BC, thinned the armour a little. I see this now as a Super-CA killer. A couple of these in the Far East could be very useful. I've decided to trim the decks down to 3.5in and keep the thicker belt but of course I could go the other way and thin the belt to 9in and keep the 4.5in deck armour but that would come out at nearly 27,000 tons.

China is a little bit concerned.

Since the first will not appear until 1948 at the earliest, the Philippines is not.

Makes me wonder if I should dig into my old archives for the CB Kamatari design...
