Fighters also resupply by being in a fleet with other ships that have an on-board supply source (solar panels, quantum reactor). In one game, I created system defense forces by fitting my old frigates with quantum reactors and putting them in a fleet with a wad of fighter. Your "fighter group" then has unlimited range within the system. If you put all the planets in a system building fighter, you can accumulate an aweful lot of them...
