Stuff for 1902

Something I am toying with. I think 1902 is a bit early to lay down a proper Dreadnaught, but since I have the tech I wanted to take advantage of it. Tan gave me this idea. Its effectively a Rhode Island with a Superfiring 12" turret in place of the 7" battery. I'm not thrilled with it, would rather finish some infrastructure upgrades to give me more Type 1 slips.
