[Strategia_In_Ultima]

Make lots of sats and form them into groups spread randomly throughout the system. Only a few sats per group need to have a sensor, the rest are just "barrage balloons" to soak up damage. If you're really rich and you have a healthy cashflow, park cloaked bases under the sat groups for extra defense. If you're constructing one per group, give it ~50% of its space devoted to fighterbays and cargo storage. If you make multiple, I suggest making four or five - three normal defense bases with good shielding and armor and many weapons, and one or two crammed full with fighter bays and cargo storage.

Alternatively, you could just lay a massive minefield under the sats....

(or a minefield AND bases)
