Reflecting on comments made elsewhere, I think that the ship's beam is far too narrow to successfully carry a quad 15cm turret. The Roanoke class with twin 6-in turrets were 70.75 feet abeam, and the Des Moines class, with triple 8-in turrets, were 76.5 feet in the beam. I can't envision a quad 6in turret taking less width than a triple 8in, so I think you'd need more beam to the design.

You have Automatics specified for the Quad-cruiser. Bruce's comparison to Des Moines and Worchester classes is far more relevant, in that case, their weapons being of the larger, automatic variety than Baltimore or Witchita.

I know, I know! Most people don't like Tromp-ish ships I can draw it, since It's one of my favoriet cruisers! Would be great if you can use it as never were too!
