The TIE Defender is a three-winged version of the TIE fighter with improved speed and weaponry, as well as shields and a hyperdrive. It is the most powerful high-production fighter made by the Empire. They are one of two Empire bomber units in Forces of Corruption, available when the space station is at Level 3.

Similar to the Y-Wing produced by the Rebellion, TIE Defenders have an ion overload shot, but they also have the ability to boost power to weapons, making them a somewhat unique squadron. Defenders are extremely powerful bombers, mixing a proton torpedo payload with the ion shot ability. They are still vulnerable to Corellian Corvettes and other anti-fighter craft, and so should be wielded carefully.
