Kind of 1920s and 30s look there isn't it?

The angled pole looks odd.  What keeps it standing and stable?

Hadnt quite goten to that yet lol not exactly sure what holds it up LOL but I wanted it to look like a Knife, and it added to the look

If we didn't have battlecruisers and large armored cruisers sprouting up all over, I'd say it was a decent design.

TBH im not impressed with BCs, why put that kind of cash into one ship when i can build 2 for less that will do the same job?

Well, the CSA doesn't see the need for BC's.
To build a ship that is made to kill cruisers without getting gaggle-F'ed into the whole 'line of battle' thing, the CSA believes in building a cruiser of large displacement with speed and survivability prioritized over armament. The only reason that these designs haven't seen the light of day is that so many so-called 'battle cruisers' are starting to show up.

23kts ships won't catch a 25kts commerce raider. Or scout for a 20-21kts battleline effectively.

Battle Cruisers seem to be the thing in the Pacific.  Mainly because we need the range, speed, and firepower that most cruiser hulls and the slower battleships can't provide.

My thing is if your spending as much as a BB on it it should preform like a BB.  If there was a fight between a 9X14 BB and a 9X14 BC which would win? The BB is the obvious answer, however The BC could easily run away... you dont win wars by runing away you win them by going into the lions den and kicking his ass.  A Navys job is as it has always been B.S.U.  (thats Blow Shit Up for you non military types).  If it has BB guns you will try to fight BBs with it, its simple Echonomics.

I would prefer Cathaginians idea of an AC but I find myself with limited options for "mutual defense" and plenty of "Colonial" powers around who I (IC) fear may try to colonize me. With a limited budget I planned Isla de Pascua as a quasi-BC to save from having to build a BB and ACs, this can do most of the job of both, plus she has far superior speed to any of the ships in my fleet, save DD/TBs.  Think Greece w/ the Averoff (I know she's an AC, but they used her like a BB) she'll be the most powerfull ship in my fleet for years cuz I can't afford to build anything bigger in the forseeable future. I'll now be able to spend my $ & BP on midsize fast cruisers and sooner than later, larger DDs basically forgoing BBs and ACs.

25+kts commerce raiders can only do that job. An adequatly protected convoy- and that is another lesson learned from the Pacific war, is nothing to be attacked with a ship that has legs and endurance, but not the stamina to take punches.

Fleet scouting force

You need some excess speed to be able to scout for the battleline, about 5kts (look at the speed difference between BBs and BCs). So you either slow down your battleline by 2kts or accept worse situation awareness. Big gun is needed to engage the opponent scouting force to deny him the information of one's position. After the enemy fleet is located, the own battleline could maneuver into advantageous position, bringing the full force against the end of the opposing battlelines.

A 23kts cruiser would have the additional disadvantage of not being able to engage 27kts light cruisers.
