With the Mecca class finished, I thought about other non-Roman ships. I started drawing and come up with a ship for Scandinavia. It was built as a response to the Roman Devestatio class, and other battleships built to counter it. Being much bigger, give or take 25 meters longer, it also had more guns for a total of 10 16 inch guns in 4 turrets. Armor belt is 14 inches thick. Top speed is 25 kts. The armor is thicker than most other ships because of steel of sub-par quality compared to other nations. The ship is smaller, but has more guns and thicker armor than the Neptunus class commisioned in 1919, but is heavier at standard displacement and 1000 tons lighter at full load.
As usual, a wip. I mostly have details left to add before I can call it finished.
