A program that never became a standard craft, the TIE/ad series is no less impressive despite it's low numbers. Intended to replace the TIE/ln in many roles, it was the first group of TIEs to carry shields and a hyperdrive. Using a long set of solar panels, similar to those that would later be used on the TIE Bomber, it is not as maneuverable as the /ln. Many pilots feel that the higher speed more than counteracts the loss of nimbleness (these apparently include Lord Vader, who supposedly had a personal hand in the design of the TIE/ad), as a good pilot can make up for poor performance, but only the Emperor can help you eek out more speed from a slow engine. They use advanced targeting systems and stronger laser cannons, but the boosted power chambers experience greater erosion than the standard models, thus requiring higher level of maintenance. This seems to be the running theme of the TIE/ad series, as all of the systems require a higher degree of caretaking for reliable function.

After the TIE Advanced x1, there would be three notable variations. The first was a custom made craft, the TIE Advanced x1.2, which was given as a gift to Lord Vader by the President of Santhe/Sienar, which he used in the Battle of Yavin. It is believed that he used this craft until it was destroyed during the Battle of Endor, resting in it's launch cradle on the Executor.
