The TIE/gt fighter was part of the TIE Series of starfighters manufactured by Sienar Fleet Systems. Physically similar to the standard TIE/LN starfighter with a ball cockpit and hexagonal solar power panels, the TIE/gt had an enlarged and reinforced hull, as well as an elongated cockpit to accommodate the starfighter's ordnance bay.
The TIE/gt was armed with a single laser cannon, and a concussion missile launcher which was designed to be modular to handle variable mission payloads. Standard TIE/gt fighter payloads consisted of twelve concussion missiles, but the launcher could handle other speciality payloads, including six proton torpedoes, eighteen air-deployed mines, two cluster bombs, or 20,000 plastic leaflets for use during propaganda campaigns.
TIE/gt fighters achieved precise targeting by operating alongside TIE/fc starfighters, which provided the bombers with pinpoint target information. Larger targets, such as buildings or capital ships could be hit without external assistance.
