To use this as an actual fleet you would also have to build 500 Escort Carriers to carry them though. Whats the resource cost for that? What good is 3000 fighters if they are grounded. You should also build an Intridictor as well so that the Enemy fleet doesn't just run away and stay clear of the planet. 3000 fighters is very intimidating, don't get me wrong, but it's not very mobile. OK Thats right I understand that point, so look 180 Imperial escort carrier 1080 TIE Bomber That are costs about 6120 for Carrier and 3240 for Bomber Suma 9360, lesser then Katana Maint : 8640, more then Katana Result: 1080 TIE Bomber + 180 Carrier VS. Katana Fleet No chance for Katana
