I don't have anything fancy to upgrade, level 3 shields and armour, hangar bay cruisers with level 2 strike craft and disruptors. nothing too fancy, none of this should require strategic resources right? that's the only thing i can think of because it's just 8 cruisers, i have plenty of alloys, and in the middle of a war i can easily win if my carriers can just get up to date and leave port.
