Here is a slightly modified Northampton class. What is different you may ask. To save you the time and effort, she has the overall measurement of the Portland class. That means the Northampton is 3 meters longer, for a total of 186 meters long. The armor belt extend all the way to the magazine of the number 2 turret, it only extended to the aft portion of the bridge in real life. The armor belt has been increased from 3.5 inches to 5, giving it adequate armor against 8 inch shells. Apart from that, she is he same as real life, only more effective as a heavy cruiser.
And a wip of what would eventually become the Alaska class; the biggest of all the large cruiser design study. The heavy cruiser CA-2D. At 261 meters long, 30 meters wide and 9,525 metes deep, she would have been a mini-battleship with her standard displacement of 38700 tons. With 212000 shp she could have achieved a speed of 33,6 knots. Her arnament was 12x12"/50 guns, and 16"5"/38 in 8 twin turrets.
