Imperator class Flight Group complement, commanded by a Group Captain, consisted of an Attack Wing of 6 TIE Squadrons, a Support Wing of various craft, and an Assualt Wing for Stormtrooper support.
The standard Wing included four TIE Fighter Squadrons (one Squadron often referred to be a reconnaissance Squadron of TIE/rc Starfighters), one Squadron of TIE Interceptors, one Squadron of TIE Bombers (lower priority ships had to make do with TIE/gt Starfighter-Bombers). Often one or two Flights in a Fighter Squadron were TIE/fc Starfighters. Sometimes one of the Fighter Squadrons was used for training purposes. By the Battle of Endor, one of these Fighter Squadrons had been phased out in favor of a second Squadron of TIE Interceptors.

Flight Group Headquarters
The Flight Group is commanded by a O-5 Captain, who functioned as a department head, they are on par with the Destroyers Executive officer, and the Stormtrooper commander, all of who reported to the Star Destroyers commanding officer, a Line Captain O-5a.
In matters concerning flight department functions, the Group Captain acts under the direction of the air deparment officer. In matter concering the operations department functions, the Group Captain acts under the direction of the operation officer.
The Flight Group has a small command staff consisting of 16–20 officers and approximately 20 enlisted personnel.
Second in command is the deputy commander, also a Captain O-5, also on the staff are an operations officer (typically a Commander O-4), a number of warfare specialists (typically lieutenant commanders or lieutenants), two wing landing signal officers, an intelligence officer, a weapons officer and a maintenance officer. The Flight Group staff is often supplemented with squadron personnel, such as the squadron intelligence officers.

The attack hangar was located on the underside on the ship and was guarded by a set of armored doors. TIE fighter service and refueling bays, and TIE launch hangars surrounded the main hangar. TIEs were launched from cycling racks and pilots boarded from overhead gantries and were released into space as they disengaged from the front position in the racks. Returning fighters landed in separate hangars and then were guided by small tractor beams into receiver-carriers. The receivers carried the TIE to a debarkation station where the pilot would exit. Once moved through the transfer tunnels to a launch hangar, the fighter could be serviced and refueled in a separate bay. In the hangar, the TIEs were cycled through a launch rack and ready for the next launch. The small forward hangar was for shuttle craft carrying high-ranking officials. The forward hangar was also used as a back-up to the main hangar.
