Boiled_Cabbage A few things: the fighters only need 1 reactor, not 3. The cannon modules only need 1 reactor, not 2. And the thruster modules only need 1 reactor for the 6 huge thrusters and the engine room, they won't always be powered, and the reactor will almost always be running out of power but that doesn't matter too much compared to how much it will cut the price. And one more, I have never used ammo storage, and have yet to give a use for it. So it would probably be better to move the ammo factories to where the storages are.
