It would be interesting if you could have a database of known enemy ships and their attack/defense at least... but I suppose you could just write them down yourself...
Interestingly, Space Empires IV allowed you to run simulated battles pitting your ships against each other or against known enemy ships in mock combat. I didn't like that game as much as Galactic Civilizations II, but it was a handy feature... maybe in GalCiv III?
