Sorry to be negative, but Battle Stations doesn't simulate anything.
Call me a hater, but it imho doesn't have a whole lot to offer/master, which is probably why you never see anyone playing online. Eveyone just blasted through SP and shelved it, which is what I did with Midway (apart from playing through SP, I was too horrified to even complete 1 mission

).
Most naval-simmers aren't looking for arcade action.
