i have some questions about ship design.first of all can i design ships with more than one mass driver cannon, or missile launcher or beam cannon? for example can i build a gunship with 4-5 beam cannons?every cannon u add is cumulative to the final attack (1 beam cannon attack 6, 6 beam cannon =36 beam attack)?it is possible to design superships with all 3 types of attack and all types of defense maximized( designing a ship without weak points) or i have to choose between what defense or what attack weapons put in?
