( I'm sorry, but I can't tell if your thinking I'm joking or not, because I am. I know a ship can't be that big, it's more of a dig at Prussia as they seem to use super tech in their role playing. I'm sorry if I mislead you. However, do you reckon a normal ship could be made a mile long?
[Technically speaking, yes, a surface ship could be. Although it would be entirely impractical and most likely have structural issues.]
