I randomly discovered a Lucky Ranger, basically a Large hull with a lot of advanced tech I don't have yet. Even buggy, it's still an incredably dangerous battleship. Of course, it should be worse:
The detailed description of the ship claims it has positronic torpedos and droid sentries in addition to heavy duty mass drivers and armor. The problem is that the ship doesn't seem to have the torps and anti-missile defenses, at least according to it's stats. It should have something like 16 missile attack and 12 defense, but it displays 0/0. In combat, it fires missiles, but it's hard to tell if they do the right damage (havn't taken it up against anything large enough to make a difference yet...).
Problem persists across saves, if you want one of the save files, TG.
