well IF you keep "Naboo" not making it "Alderaan" (which is to what Leia tells us a pacifistic society), they haven't got any planetary shields or ion cannons like we see on Hoth or Endor ...
so they could have those "fighters" more as escort (like Bespin) or for recon, if people gone missing in the woods or something ;-)
Naboo isn't the battle ready/worn world, as the others we know - so is it how I observed this
