The ship had two tractor beam projectors on the front to help starships dock at space stations, like the Ord Cestus medical station. The tugs were piloted by two clone pilots.
This type of vessel was first seen at the Ord Cestus medical station, where it helped Pelta-class frigates and other ships to dock at the station. Two of these tugs helped the brain worm-infected frigate TB-73 dock at the medical station. The infected clone troopers had taken over the vessel and Padawans Ahsoka Tano and Barriss Offee were trying to gain control back.
Tano had started the ship's cooling system, because the brain worms couldn't handle the freezing temperatures. Offee was infected too and there was a lightsaber battle between the Padawans on the main bridge. With no one at the controls, the ship was set on a high-speed collision course at the medical station. The two tugs had to use their tractor beam projectors at full power to prevent the frigate from crashing into the station.
Tugs were also used to move the Kaliida Shoals Medical Center to the vicinity of the Kaliida Nebula after its refurbishing by the Republic.
