I have to applaud Ironclads decision to make effective weapon ranges of 20+ kilometers on capital ships. I just want to say that the longer the weapon ranges, the happier I will be. Of course, these ranges are no where near those of real life weapons. Still, it beats the point blank ranges found in most space combat games. Also, I get that Ironclad needed to have fleets close enough to make battles fun and look good.
As for Spinal Mounted Weapons, I believe that I've read that the TEC Dreadnought is so equipped. There may be others.
