So, seeing as the CSA actually does have the shipyard capacity to build battlecruisers, I decided to design one. I actually designed two of them, one is a more balanced battlecruiser design, while the other is a Fisherite design and manages to squeeze out 1.3 more knots in top speed with a good bit less armor.

Balanced Design

Before I comment on the Designs which will take more time.   The CSA and a bunch of other states sort of came to an agreement.  No nation may have more then 2 Ships totaling 40K Tons Light Displacement with a 10% Error Clause.  So your 41K ton ships would violate that agreement.

Ok...

1. Engine tech limitations of 40,000 HP per Shaft your ship has over 60k Hp per shaft.

2.  Jackie Fisher would have been proud Egg Shell armed with Sledge Hammer

Other then those its not a bad ship its faster then anything else afloat because its engines are so much larger then anyone elses more SHP per shaft then anyone else by 50%.

Reading the CSA tech list, it said that 1917 technology gave unlimited power per shaft. If that isn't the case, any advice on how I could go about reducing the HP per shaft or otherwise make this ship able to reach a speed of at least 32 knots?

snip

IIRC (which I may not as it was before my time here), the CSA tech list is an older one that should probably be moved over to the new rules (along with a few others)

On the ship itself, well I am an armor junky (almost worse then Valles ;D). Im not opposed to BCs, but I like the German style ones better. Aside from the already pointed out rules and treaty problems, your getting better. What I find helpful is to pick a historical design that is close to what I want and modify it to suit my needs. Do you have access to Conway's All the Worlds Fighting Ships?

Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.

This is actually a CSA version of a Lexington, with about 70,000 more horsepower and torpedo blisters.

I am in favor of heavy armor myself, but I do love battlecruisers. They are the Rolls Royces of the navy, and far more impressive than the fast battleships because of what they have to give up for their speed.

The problem is a 40.4 kton ship is a HUGE ship, you are only allowed to build two ships of 40 kton with 1% leeway under the Richmond Treaty.

Now that you have a 7" MB, that's just a huge national loss waiting to happen. You don't need to go 34 kts, I recommend dropping the speed a bit so you can at least have semi-decent armor.

I would consider a 32 kt design with better protection to be vastly better. Honestly speaking, 2 knots doesn't net much value in exchange for the golden twinky status.

Well, with it being overpowered anyways I will be working on the design tomorrow in order to bring total HP down to 160,000, increasing armor. It will thus become either a fairly high speed battlecruiser or a fast battleship. I will probably make a few lighter battlecruisers with very high speeds later on though.

8 X 15", isn't overpowered, it's somewhat underpowered for it's displacement vs. it's protection.

For that, it should either have even more firepower or more protection. :-\

I meant in terms of propulsion, not armament. It has twin 15 inch gun turrets because that is the largest gun and turret in the CSA, but I suppose I can always develop 16 or 18 inch guns for the ship. 15 inch guns are pretty good for their weight though, and I do think that armor is more important than more powerful guns. I'll have to see how much weight is added by the 16s and 18s, although 18s are pretty heavy for what they offer in real life and also from what I saw when toying around with my first Springsharp ship.
