Also, Gunboats might be designed to take out fighters/bombers but they really are useless unless it's 1v1 or you have rediculously more GBs than Bombers/Fighters. xD
My suggestion to all capital ship owners is to only mobilize your capital ships if there is a threat or objective that requires capital ship support. There's far too many capital ships that just sit idle, I call them bomber meat, because they're just waiting to die.
