The USN had concluded that the armored cruiser as a concept had reached its last legs, and the class either had to evolve or be phased out. Two choices stood before them, either uparmor and upgun the ships (as they wanted irl, but the challenge won't permit 12" guns and battleship-grade armor,) or make the future cruisers more relevant by increasing firepower by adding a larger number of smaller primary guns. My entry goes this direction by using the 8"/45 Mk.6 gun in twin mounts with two mounts fore and aft, and four mounts amidships in a hexagonal layout. The secondary battery consists of 14x5"/50 Mk.5 guns in casemate mounts and the tertiary battery consists of 18x3"/50 Mk.4 guns in casemate mounts and 22x47mm Hotchkiss guns up in the superstructure. Due to their added size, the armor is thicker than the previous Tennessee class, and on par with the Pennsylvania class, and the ship retains the same top speed of 22kts. Overall the ship retains the same lines and appearance with the previous classes (lots of sheer on the bow and stern for added seakeeping, two military masts and four funnels.) As commissioned in 1908 she sports the white and buff peacetime colors and she's among the first ships to use the newly developed Norfolk 65-A anti-fouling paint, instead of the more vibrant commercial red paint used on previous ships.
