I don't know, haven't tried it yet. Fighters can't have shields, though, which buggers me much more right now
... and they also can't operate alone without a carrier around. No wing of Shivan fighters suddenly appearing out of nowhere then, I guess. However, I managed to at least get the visual appearance of a subspace jump-in for fighters by adjusting the default undocking/docking animations. Undocking fighters now seem to appear out of subspace, so cruisers can now be accompanied by fighter wings without needing a proper hangar bay. Only drawback is fighters only being able to jump in/jump out next to their "carrier". Still better than nothing, I suppose.
After fiddling around with all these fighters I may need to add an engine trail to them, unlike Freespace... otherwise they're just very hard to see when being zoomed out. It would be great, if Nexus automatically placed icons on top of these squadrons when they're getting too small to see (much like Supreme Commander), but sadly it doesn't and there's no way a mod could change that.
