Basically, it's Coalition produced to provide a sturdier and cheaper alternative to the Libertonian made Enterprise class liner, while being less specialized and able to be a modular design that can be refit when needed, if you need a prison liner, it can be refit for that purpose, need it for diplomatic duties such as an ambassador's ship, or as a luxory liner, etc etc. This is to allow a more broad range of possible RP than I feel the smaller ships allow.
Turrets on the model aren't going to stay, they are merely there for show. The ship would be about the length of a Rheinland battleship.
