The RZ-1 A-Wing Interceptor (aka A-Wing) was a kind of touchy little craft, and required great skill to pilot. A-Wings did not use astromech droids. Like the TIE fighter, the A-Wing left little chance of survival after a collision.
A-Wings are found in Episode VI. The most notable A-Wing is the one which crashed into the bridge of the Empire's super star destroyer, which in turn crashed tip-first into the second Death Star.
