I have done three different designs on the South Carolina as a full sized dreadnought battleship, instead of her real-life design, which was a pre-dreadnought posing as a dreadnought. Seriously, though, the South Carolina class was 138 meters long, compared to the 155m of the Dreadnought. My fourth design for an "alternate" design for the South Carolina is a semi-dreadnought design. It keeps the overall size of the original real design, but switches around the arnament. She now has only four 12 inch guns, but has four turrets amidships with 10 inch guns from the Tennessee class armored cruisers. She also has the six inch casemated guns mounted in the hull.

It's not a good looking ship, but certainly a well done drawing. Keep it up!

I highly approve of this concept, the more demented a ship the better.

I have a bonus joker card idea. Make another version with 'uniform' battery of 10in guns, but with EVERY turret being two story with 7in guns above the 10in battery, and upgrade the casemates to 7in too.

I love this stubby industrial little monster, good job! The elevated platforms for the 3" guns to clear the secondary turrets is specially interesting.

Those platforms are on top of the turrets. As for stubby, it's the same size as the real life South Carolina. The super structure is longer because I removed the superfiring turrets.
