TT4475 was one of three Delta-class DX-9 stormtrooper transports employed by the Rebel Alliance, along with a Corellian corvette Hart, to extract officers from the frigate Anvil which had been severely damaged while trying to receive supplies and needed to be abandoned. 3 X-wings, one of which piloted by Keyan Farlander, provided support and cover against Imperial forces so that the convoy of ships could escape to Hyperspace. Farlander then scuttled the frigate to prevent its capture.
