Altered version of RFS Markgraf Posadofski, altering the hull form to be much simpler, adding superfiring to the main and secondary battery gun turrets, increasing the amount of ammunition available to more realistic levels, and acknowledging that miscellanious weights are a thing. It also adjusts the trim of the ship to improve seakeeping and gunnery characteristics.
