In my short time in this forum, I've noticed one thing everyone agrees on; the Kilrathi war was a fighter based war, with ships launching waves of fighters to attack attack enemy ships. Carriers were key in this war and cruisers were used as light carriers/ strike and escort ships, destroyers were escort ships with the occasional assault duty, and frigates seemed more like recon ships. All of this being the reason for the lack of Endor-style battles, be that the case, then what is the purpose of the battleships (mentioned in the books) and dreadnoughts (Sivar, Concordia etc.)? Battleships are meant for ship to ship combat, as are dreadnoughts with the big gun that makes up the keel.
