The Eta-3 Jadis-class light TIE starfighter was an experimental fighter used by the elite Storm commandos, developed for use in missions that would likely result in many casualties of unshielded craft such as the TIE starfighter and the TIE/in fighter. The Eta-3 managed a temporary collaboration between the most potent developers of Sienar Fleet Systems and Kuat Systems Engineering. It was supposedly the predecessor of the TIE Hunter project, which became the main fighter of the Storm commando fleet. Some very important figures used these vehicles as a faster, better shielded, and more heavily armed alternative to the TIE fighter, including Darth Vader prior to his test run of the TIE Advanced x1.
