comments pls
With 1909 engines we are limited to a maximum od 12 000 shp / shaft. So the ship got to be slower as the max shp she can have is 48 000.
Also the ships needs more misc weight, around 250-300 tons should be enogh.

I dont consider Ultor class as dreadnougths,to few guns,in my wiev I consider they are semidreadnougths .
The bunkerage is excessive, and unless you have a domestic source of oil, I'd recommend sticking to coal-firing.
I can't see the secondary and tertiary batteries fitting amidships, unless the secondaries are to be hull casemates.
I'd vote for heavier deck armor.

She is still over engined, less so, but still significant.
The total number of main guns she have is the same as the Ultor-class.
But she really need thicker deck armour, 25mm is ok on a light cruiser, not on the pride of the fleet (but it is twice what the ultor-class have, so it is an improvment).
The amount of coal is insane, considering the enormous difference in draft she will have between normal and deep draft i would say the main belt need to be at least 1 or 2m higher/deeper just to compensate for that. Reduce cruising speed to 15kts and you could cut the coal bunkers in half, to 1/3 if going for 12 kts.
Finally, 8x30cm guns are a fairly light armament for a 23kton ship.

Another revision due to "black info"
Ahoj!
Had to revise my post, as you posted yet another design. But most of my comments still hold. Korpen is correct on speed and range - 6-8000K nm at 10-12 knots and you should be a happy camper :)
Sorry, no rest for the wicked :)
Remember - half of the Main Belt is below the waterline.
We can't go over 4 shafts - that's the absolute limit.
But I'd say you are almost there, as the design is concerned.
4 shafts at 12,000 SHP each should give you a speed of 21, which is enough. That will allow you to mount a fourth Main Battery turret. I SEE YOU DID THAT :)
Cut back on Main Gun ammo to 80-110 shells, and the number of 6 inch secondaries to 12-14. Maybe swap End Belt and Upper Belt thickness?
I'd cut the Main Belt to 12 or 13 inches, and
- extend MB by 4 feet, and Upper Belt by two feet
- thicken upper belt to 8 to 10 inches
Yet another possible tweak is trim - you have excellent fire platform, but not so good stability - try to bring to up stability to 1,15 - that will make the ship more survivable.
ATM Main Gun barbette thickness is not OK, as there is a 4 foot gap between Upper Belt and weather deck, where the paper thin 10 inch barbette is exposed. If you bring the Upper Belt to weather deck level (and to 8 inches or better), then the 10 inch barbette will be enough. If you decide to use superfiring turrets, then I suggest 11 inch barbettes minimum. And then you can leave 8 feet of the sides unarmoured - or thinly armoured.
Borys
To many shafts we are limited to no more than 4 shafts sry man I thought of the same thing =P Do you have superfireing? If you do you also have triple turrets. in which case id suggest something like my light bb plan 20kts, good armor, and 3 trip 12" turrets one being superfireing.
Ahoj!
An example of what can be achieved on similar displacement and armament.
http://www.navalism.org/index.php?topic=825.msg11120#msg11120
I am building two such ships, and plan to order a third.
Borys
I'd go with 14" guns. You should also make B and X turrets superfiring. As Khymerion started researching it back, it is available to you 1909 the latest.
150 shells per gun... on the high side, but SS default.
The 6" guns must be placed in the casemates, turreted 6" secondaries are a bit early (according to the rules). You don't need 18 of them either. 105mm is too large for tertiaries, make them 3".
Upper belt should be thicker (6-8").
5.47m freeboard would require 14-15' main belt (upper belt height is usually one deck, roughly 8') to have continuous coverage up to the weather deck. Or decrease freeboard.
Armored deck should be at least 2".
Torpedo Bulkhead 1.5".
Turret face should always be thicker than the belt.
Barbette: you have ~13" equivalent protection if you increase the belt. However, if you make the turrets superfiring, make it thicker.
You are limited to 4 shafts and 48000SHP.
You don't need such a huge range, it costs a lot of (both light and normal) displacement, especially for coal. 8000@12 would be adequate, anything more is just wasted.
Misc. Weight: the 200-250t Korpen is quoting is for other equipment and and displacement reserve. At least 100t should be needed for a battleship.
Size: limit length to 170m to fit in lvl 2 drydocks you have overseas - and lvl2 shipyards so you could build her.
Once again to the drawing board lol.lol
You'll get used to it lol. It is a very rare ship that gets posted that someone cant find a flaw in.
How do you make turrets superfiring?

The total number you have checked in gun "above deck" and "below deck" are greater then the total number of guns.

Thin out the end armour, add 3 feet to the Upper Belt, and you've got it made. Better than my suggestion.
Of course, the issue of Type 2 Slips and Drydocks stands.

You are still enamored with the range. You don't really need to armor colliers with 14" guns.
he is right (looks for the falling sky as he knows the world is ending if he agrees with P3D) go down to 6000 @ 10 or so you realy dont have that much ocean to cover.

Nice, now you can cut on or two thousands tons from her displacement, as your overall hull strength is more then 1,00. :)
I think 6000nm@10 won't be enough for a BC dreadnought. Baltic lines of communication to the colonies are much longer than what Italy has. I suggest steaming distance from Trondheim to the South Atlantic isles, and from those isles to Gujarat should be the range requirement.
Other places where you can shave off a bit:
- one inch or two from barbette armor, no need for thick armor below the weather deck.
- half an inch of deck armor
- decrease freeboard
- bow angle should be closer to vertical, rather 15 than 45 degrees.
Other changes:
- change to 4 shafts instead of 5
- increase torpedo bulkhead thickness.
- I'd exchange 8 4" guns for four 6" ones
- increase secondary armor to 6"
Ahoj!
6000-6500 nm seems OK. That's the distance from Norway to the Chuvosa Islands (the big South Atlantic archipelago). As to taking the long way around, through the GIUK gap - if the Normans and or the French block the direct routes (La Manche, Suez), then the war most likely is with them - and they are close at hand :)
And there are friendly neutrals on the way - Iberians, Austro-Hungarians ...

Quite nice, Sachmle. But I'd give her more beam, to improve stability. The trend on the board is that 1,10 seems to be the minimum.

*pokes head up from the foundries*
Nice ship you have there... Seems time has been good to you... centerline and superfiring and all... *looks at the well weathered drawings in the forgotten and dust covered drafting rooms* Wish we had that in my day...
oh im not BC I was proposing a design that Italia is capable of building. (to my knowlage im still the only one that can do SF and all centerline) Although everyone else is closing in on me fast in that respect (and i still only have one of them ><)
Rohan is ahead of you slightly in that field, just they have been quiet on the shipbuilding front for a little while (still need to put up my sim report). Rohan has just finished a nine gun Battlecruiser armed with 12 inch guns in triple turrets and is abut to lay down a third to its class. New Rohirrim ships will probably be designed for 1909. The teo Battleships currently uner construction are armed with eight 14 inch guns in twin turrets. Both classes use superfiring turrets. Rohan was also the nation in Navalism to build ships with stacked turrets (like the Kentucky and Virginia classes) useing twin 9 inch guns over 11 inch guns. This did ont work so good, bt the ships are presently retained as coastal battleships.
The Baltic Fleet needs to be able to make any Russian or Ukranian attempts to move on the Swedish or German coast. The Northern Fleet needs to be able to engage the UKA and perhaps French Forces in at least a standoff engagement if things ever turn bad in the North Sea or Northern Atlantic.
CSA can do it as well, just hasn't yet as the Nuevo Leon class was conceived prior to our being able to build them, and has been judged adequate for the next 5-10 years for general service due to weight of shell and armor protection.
But you better believe that the CSA has all centerline, superfiring designs in the works.
hehehe i figured as much thats why i said to my knowlage, I knew someone else had to be capable of building them, also i just got 14" guns. my bbs cary 12" mains atm im working on a 14" bb but im not sure ill be able to build them any time soon.
Ahoj!
I just discovered that this ship is a little beyond available Baltikum technology.
