USS Arkansas built 1899-1903, would this ship even be leagal? This ship looks like a cheat not a OP cheat but effectively with almost no way to shoot out the sides unless the opposing ship gets in close...
Is it the year the keel was layed? Or just the fact that is is considered a one of the last monitor type ships? I really cant imagine this ship being see worthy other then coastal or river usage.
I could not see those particular ships ever being built in Big Gun *or* Fast Gun. Leaving aside the issue of construction dates, It's just too small to effectively fit all the necessary gear. In scale, this thing is 21 inches long with a maximum draft of 1 inch. In order to build it, you would likely need to add extra depth to gain the space and displacement necessary. You could get similar performance from later WWI-era monitors like Erebus, Roberts, etc. without needing to add depth or otherwise compromise the design. I absolutely adore the style of early-period ships. But I also appreciate a ship that is practical to build and maintain, which is why I focus more on large predreadnoughts. You can get the same aesthetics and maneuverability, while getting a much more practical and maintainable platform.
