Shuttle TY992 was acquired by the rebellion during the Age of the Empire. In 2 BBY, the rebels Kanan Jarrus and Rex used the shuttle as part of the secondary phase of a mission to rescue the rogue Imperial Security Bureau Agent Kallus. While their initial plan was to rescue Kallus from Lieutenant Yogar Lyste's Arquitens-class command cruiser, Kanan and Rex were forced to change their plans after Lyste brought Ezra Bridger aboard Grand Admiral Thrawn's Star Destroyer Chimaera.
After Chopper obtained the necessary clearance codes, Rex and Kanan were able to land in the Chimaera's hangar bay. Following a brief fight involving Governor Arihnda Pryce and Lieutenant Lyste, Rex and Kanan managed to reunite with Ezra and the droids Chopper and AP-5. However, Kallus elected to stay behind to continue helping the rebels from behind Imperial lines.
