Indigo Squadron was a fleet of the Rebel Alliance that saw action during the Galactic Civil War. Airen Cracken, a General and the Chief of Intelligence within the intelligence gathering branch, had his base of operations on one of the starships within this fleet.
Not long after departing from Trading Post Sh'ung-tesk, Doctor Chelli Aphra encountered Indigo Squadron and General Cracken. The Galactic Empire had tracked her down to Arbiflux. Aphra had previously declined to assist Cracken with using the Farkiller in a scheme to assassinate Emperor Palpatine. Although she stated she was there to help, Aphra's real intention was to recover the Farkiller and sabotage the assassination plot. She hoped this would make the Empire view her favorably and reverse their decision to execute her.
This fleet was composed of an MC80A Home One Type Heavy Star Cruiser, a trio of CR90 corvettes, a pair of EF76 Nebulon-B escort frigates, and three GR-75 medium transports. T-65B X-wing starfighters and RZ-1 A-wing interceptors were utilized by the fleet.
