Bavarian AC

[Kaiser Kirk]

I've been toying with the idea of fielding a large cruiser.

While getting into the BC size range, that's not really the intended role. The concept is that one or two of these could be the center piece of a light  cruiser squadron.  The light cruisers would fan out as raiders, relying on radios to keep in contact. If heavy opposition is met, or a guarded convoy, the raiders would coalesce on the heavy unit(s) for fight..or be bailed out by same.  Looking at the cruisers P3D just posted, it appears reasonable.

Anyhow, as I note I've finished my first turret- a twin 10" in HY1/1919, the vessel becomes possible.

The armor deck is split between a 25mm deck capping the upper belt and the main 50mm deck capping the main belt, bolstered over the magazines and machinery (since the upper deck doesn't cover ends).

[P3D]

Bulges are a very bad idea if you don't have any TDS.
Armor is too heavy. Secondaries should be in deck mounts.

[Marek Gutkowski]

I think that you can get the 150mm on the freeboard without sacrificing to much.
Well You armour is high, I wonder what kind of role they will have.
Your plan of using them is not too my liking. I a defensive situation a early dreadnought will have a field day with them. Also two of them attacking a convoy with a single old dreadnought protecting it will not be easy or wise.

Kriegsmarine Schranhorst and Gneisenau were ordered to retreat if a convoy was defended by a QE or a R-type battleship. This ships will find themself in the same situation with a dreadnought.       

[The Rock Doctor]

I'd suggest a taller, but thinner, main belt for her.  The current ten foot belt does not protect a lot of the ship's sides, really.

[Kaiser Kirk]

A. Until Bavaria starts operating beyond the Med, I don't think they will see the deficiency in casements.  Further, with modern torpedo ranges, the elevation limits imposed by casements are still acceptable.

B. The tactical wisdom is indeed open to question. These ships could only hope to take an older DN at range, relying on low hit probability deck hits, however I am thinking that a single PD/DN can't catch a cruiser squadron, and if the opposition wishes to commit DNs to convoy defense, it's a draw on their resources. Further, if they don't provide adequate screens, the CLs could press a torpedo attack.

C. Armor. I'm not sure what the proper set point should be. The 7" of the Luitpolds could work well enough, but  The DKB with their new 9.45" and older 11-12", the Hapsburg 7.5", even the NS with 8-10" are potential opponents. I'd rather be going up to 10-11", but can't manage that well, so 9" seemed minimal.

C2. Armor height : The main belt is intended to extend 1-1.5m above the waterline, with the remainder below. The 2-deck tall upperbelt to the freeboard. This makes her pretty proof against the lighter cruisers, but allows a thick enough belt to protect against the heavier ones. I suppose I could try adding another deck level to the main belt at 7".

E. Bulges :  Bulges historically were used prior to interior TDS, they are not as good as they suck up SHP and make the hull beamier. Further these are small enough as to provide negligible depth, they actually would be of more use against near miss bombs- which isn't a consideration yet-  but have some slight value.  Incorporating a full TDS drives the vessel size way up.  Bavaria only recently figured out the concept of "TDS" anyhow.

[maddox]

She's armored up to the French 140mm guns. And that counts for a lot in the Med. 
(on the other side, I believe the French Med fleet is a laugh, and is designed to give anybody else in the med a safe feeling)

[Kaiser Kirk]

Well here is a re-work without the bulges and with a taller but thinner belt.
I don't like it as well, it may stop the 8-9" rounds, but it's not as useful against 11-12".

The upperbelt extends to freeboard in this region. Main belt extends 2.5m above and 2.5m below WL.

...I don't like it as well...

You could made a mixture between the 1st & 2nd SS...

Built "your" Indefatigable.


Jef

[Kaiser Kirk]

Well Jefgte, then she starts getting even larger :)  Earlier versions had her lighter and slower, but I decided 28-29kts was needed. As it is she can make 26knots on just the coal-fired boilers.

And I really should have referenced Von Der Taan than Indefatigable, I was just trying to use the main battery arrangement as an illustration, forgot VDT had the same and the thicker belt to boot.

[Kaiser Kirk]

Well, if I ditch the seakeeping I can keep the displacement the same, while bringing a 9" main belt up 4m, so it's +/- 2m from WL, with the upper belt carrying to freeboard.
I can also bring the # of secondary guns up to 16.   Overall this isn't bad. One thing I worried about the first design is if the investment in seakeeping was reasonable for a navy that has yet to leave the Med.

Similar to the OTL Von Der Taan in battery layout, with the mid ships turrets en echlon.

Main belt is -2m to +2m WL, with the upper belt carrying to freeboard.

The armor deck is split between a 30mm deck capping the upper belt and the main 50mm deck capping the main belt, bolstered over the magazines and machinery (since the upper deck doesn't cover ends).

Could trim it up a little. 1.27 is a little high for stability. It won't do much for seakeeping, if anything, but you may get a 1.02 or 1.03 out of it. If anything it will improve your gunnery platform making hits more likely (or one would assume). Not that 50% is unacceptable or anything, it's quite fine IMHO.

As to seakeeping for a nation who's never operated outside the Med. I'm sure that even without an operational experience you would still have anecdotal evidence from the Dutch, Confederates, Italians, etc..

[Kaiser Kirk]

Hmm... I don't think I've ever been told I had too much stability before :)

Adding a meter to the forecastle and setting the trim up to a whopping 69...gets me slow & easy roll and a seakeeping of 1.02, stability 1.11

edit : I thought there was something in the design guidlines about max trim, can't find it. Reworking the ship quickly, I can manage 1.2 seakeeping and 70 stab...if I deepen the draft and drop the BC to 0.494...a little low for such a ship.

Trim between 30 and 70; no questions asked about the ships. Below or above, eyebrows will be raised.

Idem..

Hull forms & calculation are not optimum

You could have;   
Ship has slow, easy roll, a good, steady gun platform...

Hull form is still the relatively chunky one, but this has the trim set just under the threshold Maddox cited, so gaining that slow & easy roll.
