Shuttle TYA77, a Sentinel-class landing craft, served as transport for Ezra Bridger to the Chimaera, along with Agent Kallus and Lieutenant Yogar Lyste.
The Shuttle TYA77, being a Sentinel-class landing craft, was designed with a tri-wing configuration. It was assigned to Lieutenant Yogar Lyste's Arquitens-class command cruiser and its purpose was to transport personnel.
During 2 BBY, Agent Kallus and Lieutenant Yogar Lyste were transported via Shuttle TYA77 from Lyste's light cruiser to the Chimaera, Grand Admiral Thrawn's Imperial Star Destroyer. Accompanying them were the captured bounty hunter Ezra Bridger along with the droids Chopper and AP-5. Lyste intended to display Ezra as a trophy, demonstrating his victory, while Chopper and AP-5 were ostensibly there to present evidence against Ezra for his alleged theft of a Star Commuter 2000 shuttle from the Capital City spaceport on Lothal. The reality, however, was that Ezra and the droids were involved in a rebel scheme to rescue Kallus, who was secretly the rebel informant known as Fulcrum.
The initial appearance of Shuttle TYA77 occurred in the Star Wars Rebels Season Three episode titled "Through Imperial Eyes," which was initially broadcast on February 25, 2017.
