In the next session of my campaign the PCs will rendezvous with a Gozanti-class (secretly affilated with Black Sun) above Mustafar to deliver an important datacard. However they may be tracked to the system by Nagai raiders who want the datacard. The Gozanti will engage the enemy starship, while they ask the PCs to engage the fighter craft (the Gozanti may or may not also have a complement of fighters, possibly Dagger-class). The PCs are piloting an unmodified YT-1300, so we have their vessel and possibly four allied fighters vs some alien fighters. So any suggestions of how many fighters and what stats to use (these will be fighters of Nagai manufacture, but might be use the stats of existing fighters, but reskinned)?

I like TIEs as templates for basic enemy fighters.... They don't have shields or missiles and tend to blow up at nice round numbers of 5 HT damage each...

If your players aren't all that familiar with the various pros and cons of the fighters (or even if they are), fighters with the following make excellent minions to blow up: 5 HT, 2 armor, twin light laser cannons (5 base damage), no shields. Since speed doesn't really matter in space combat - per RAW and for most things - it doesn't really matter what speed they are.

If you want them to be tougher, increase the HT and armor slightly. If you want them to be a serious threat, add missiles -- concussion are dangerous to pretty much anything and proton torpedoes can take down capital ships.

If you want cannonical examples, try the following: Cloakshape, Dunelizard, Starhopper or Scyk.
