The TIE/ad starfighter or TIE Advanced was the culmination of a series of starfighter designs first explored with Darth Vader's TIE Advanced x1. To avoid confusion with Lord Vader's personal craft, it was known better by its nickname TIE Avenger. Incorporating the previous successes of the TIE Series starfighters, along with those of the Rebel Alliance, the TIE Avenger was one of the first production starfighters to break away from the Imperial doctrine of quantity over quality. Incorporating deflector shields, a hyperdrive, and warhead launchers, it was also significantly faster and more maneuverable than any existing Imperial or Rebel starfighter, so enemy pilots nicknamed them "brights".
