TIE Advanced x1

The TIE Advanced x1, also known as TIE/x1 or TIE Interceptor prototype, was an advanced prototype starfighter touted as a replacement for the standard TIE Fighter tested by Darth Vader and X1 at the battles of Yavin and Mustafar respectively. While it never made it into production, many of its best design features were later incorporated into the TIE/sa bomber and TIE/IN interceptor. Further development of the Advanced continued, eventually leading to the TIE Avenger and TIE Defender.
