What would a world without cheery trees be like ?
First I assume that everybody would run out of cash and or will power after a few ships, I assume RN only builds 4 ? G3s / IJN builds the two Kaga-class battleships, and two Amagi-class battlecruisers ? USN builds 4 South Dakota 2 Lexington ? (is that a reasonable mix ?) but bye 1935 people will be starting to look at a new class of ships.
So GB starts to lay down what will become the KGV class due to the giants around nobody will build less that 16inch and very big !

My very WIP would anybody like to give any suggestions ?

It's an interesting idea, your super firing gun looks far too low to the roof of the turret below it though in my opinion. The lower turrets too look a little too close together as well, quads? I would imagine the RN would space them out as there was still fear that a single hit near close turrets like this would take the ships entire main armament out of service.

Indeed, an interesting idea. Be good to see how this shapes up.

Personally I like Nelsons and g3s (does that make me weird ? :oops: ) but since in real life the RN didn’t like nelson by 1935-7, I have to think that they might not like the G3 (but maybe they didn’t like nelson due to it reminding them of what they might have had without WNT ? :? ). So I have gone for a mixed ABX rather than ABC or ABQ.

My WIP no detail as yet just put it up to ask if you agree (or not !) with the basics ie guns (3x3 16ich 12x2 4.5s and 8X8 40mm) and directors (G3 looks like it used new very big ones that might have been upgraded and reused if they had been built) I have used 6 secondary HACS for my 4.5s, what do 40mm use ? I have added a cat with a hanger farward for a few spares as all 1935 BB's have them.
Thanks JSB

Yes. Yes that does.

Personally I like the more traditional layout of the second design better but that doesn't mean you couldn't make your first layout work if you spaced the turrets out a little differently and changed the heights. There is an argument to made that the RN would have continued in that direction if the g3s had proven successful.

Keep it up I love alternate designs from this period (damn that Washington Naval Treaty). I plan on drawing a follow up fast BB design to the SoDaks as an American response to the g3s and IJN fast BBs. I just need to find the time, but new drawings like this one and Karle94's keep wetting my appetite.

my ABC very front heavy G3+, I think this would be a good bb to hunt down bismark or italians but I will admit that it might not be so good at parking in windy conditions or keeping no11 happy with the peace time fuel bill.

I have updated (above) my G3 follow on.
A few q's

1) should I add more 40mm's I have 8x8 but I have room for 6 more on the big flat superstructure?
2) internal or external belt (ie g3 or KVG or Iowa ) and all the arguments of what is better (and more importantly should I have portholes) ? (I have 14inch at 18deg in my springsharp)
3) should I put railing all the way down the side (where it may block the 4.5's )?
4) boats in the stern ? (never used for real by the RN but harks back to some fisher drawings ?)
5) how should I finish her off (and make her a bit more interesting, she’s has just a bit to much grey ?)

Thanks JSB

1. I think you have an appropriate amount of AA for a 1935 design, I would reduce the amount of superstructure amidships and maybe use that as the boat deck or put the hanger and catapult there. The superstructure just looks too big to me, especially amidships. Personally I would reduce the entire superstructure by one deck at a minimum.
2. I'd go with an external belt, its easier to repair, but may cause slightly more drag. 18 degrees is a lot, Hood only had 12, the more its angled the shorter it is. portholes look good forward adn aft of the belt
3. I would have a full railing, maybe check the other british ships with 4.5" guns on the main sight and see what they have.
4. boats on the stern where the crane is makes sense
5. you could consider adding some medium sized guns like 6 or 8 inchers. the 4.5 is a good AA gun but it would be underpowered against the big axis destroyers and Nelson, G-3 and N-3 all had at least a 6" secondary.

I wholly agree with Syzmo's erudite analysis, except that I'd cut the amidships superstructure down with two decks. As for the 4.5" auto turrets, I wonder, did they even exist as early as 1935? If so, why then wasn't Warspite given them? No, I'd suggest following Syzmo's advice about the 6" Nelson-style secondary armament. Makes a whole better sense!

A very nice effort, and yes, I tend to agree with the above, give her 6" secondaries (like on HMS Nelson and HMS Rodney), and for AA give her 6 single 4.7" (also from the Rodney and Nelson).
I would also cut down the superstructure amidships, as it is now, it's more fitting on an ocean liner than a battleship.
