Adding some supply ships to your fleets always helps. Adding some now means you'll reduce your current supply woes and you won't need to add as many later on when your fleet gets bigger.

Launching fighters does not cost any supplies.
Fighters have full supply when launched.
Its when you have the fighters in the same fleet as ships, that you lose supply.
Use shift-click to make the fighters move with the fleet when you need them to.

To control the grouping of fighters, you can use the strategies to launch in groups of 5,8,10, etc in combat.
Outside of combat, you'll have to launch one group, move them away, then launch your next group. Otherwise they'll all bunch up into one huge stack.

Any fighters launched (outside of combat) while there is a fighter group in the sector will be added to the existing fighter group.
