3 minutes ago, UnitOmega said:I believe the technical definition of the X-Wing is a "Strike Fighter", that is a multirole fighter/bomber or attack "plane" which puts as much emphasis if not more on the ability to engage in space superiority as to engage hardened targets. The Y-Wing is a more traditional fighter/bomber. Multirole vehicles are pretty brill in SW, which is why the X-Wing is such a big deal. That, and canonically the empire has yet to produce a proper multirole spaceframe.
The TIE Defender is about as multi-role as you can get. Its lasers alone make it a threat to ships as large as the Ghost (oh, spoiler alert), and they traditionally had a missile bank to take out larger targets. They also have the speed and heavy shielding to take fire from capital ships and survive. They were multi-role, but too expensive for widespread use.
