The TIE/gt starfighter was based on the standard TIE Fighter design but with the main pod elongated to accommodate a bomb bay. It was designed to be dependent on the TIE/fc starfighter, which provided precise targeting information; however, many larger structures could be destroyed even without the TIE/fc's assistance.
After the introduction of the TIE bomber, the Imperial Navy transferred the TIE/gt to outlying posts, lower-priority assignments, and the Imperial Army as quickly as the datawork could be filed; however, Army resistance and legitimate lack of demand slowed down the process considerably.
