Imperial Transport Pilots were Imperial combat drivers specifically trained to control transport skiffs located on the planet of Mustafar. Their uniform consisted of white armor adorned with blue symbols, similar in appearance to Imperial stormtrooper armor, but they used helmets like those of Imperial combat assault tank pilots. These Transport Pilots were stationed at an Imperial base that was situated close to Mustafar's Fortress Vader. During 1 BBY, Rebel Alliance spies, who had infiltrated the base by posing as stormtroopers, compromised the base; one of these spies, Athex, was disguised as an Imperial Transport Pilot.
The concept and design of Imperial Transport Pilots originated with the virtual reality experience Star Wars: Secrets of the Empire. The 2018 LEGO Star Wars Darth Vader's Castle 75251 set officially identified their designation as "Imperial Transport Pilot."
