Last Sunday I ran a massive fight between a Jem’Hadar battle cruiser, a Klingon battlecruiser, a starbase, and the PC’s ship, and I KNOW I missed a ton of rules when I did it.
That prompted me to pull together the rules for starship combat together into a concentrated document. Currently, lots of cogent bits are buried in ship creation, ship stats, and starship combat sections of the ship.
I actually think the rules feel very Star Trek, they just are scattered across the book. So if you play STA, and want to remember more of the starship combat rules, I hope this reference helps.
