I'm also curious why a cruiser is called the "South Carolina class". State names were reserved for battleships, cruisers received city names.
This design is also a bit incoherent -- why are you shipping a bunch of fancy ship's boats, a decidedly pre-war feature, yet at the same time you've got the radar fit of the post-war Oregon City or Fargo classes? Minus of course any surface search capability which you seem to have ignored!
The ship seems to be stuck between years. For pre-war features, you have .50-caliber machine guns, a large boat complement, an enclosed bridge, and a large spotting top. For mid-war features, you have the Kingfisher floatplane, a scattering of heavy AA in the form of twin Bofors, and the Mk.34/8 GFCS combination. For late-war features, you have the extremely modern (for WWII) SK-2 and SP mix, albeit without any form of surface search capability.
The first thing you will need to do is pick a year for this ship to be displayed in, and then do some research as to what components should be present.
This is the evolution I would imagine:
1939:
- 8-10 .50-caliber machine guns, IN TUBS and not along the rails like you have, this is a distinctly modern USN feature
- No machine cannon (delete all 40mm Bofors)
- Enclosed bridge like you have
- No radar fit
- Mast tops have crow's nests and yardarms, complicated rigging system some of which are HF radio wire antennas
- SOC Seagull float plane or earlier
- Armored conning tower ahead of the bridge
- Fancy spotting top like you have
1942:
- Start reducing the size of the bridge
- Remove armored conning tower
- Reduce the spotting top, add 20mm Oerlikons in tubs where the spotting tower used to be
- Add 1 or 2 Bofors mounts
- SC air search radar on foremast, SG on stub mount above the bridge
1944:
- Delete the bridge and replace it with an open bridge a la Fargo or Oregon City
- Cram as much 20mm and 40mm AA as possible
- Mk.51 directors for 40mm fire control
- SK air search radar on foremast, SG on topmast above it, backup SG on mainmast
1945:
- Add ECM gear
- SP height finder on mainmast, relocate aft SG to topmast
This ship has no secondary battery?
