TB-73 was a Republic Pelta-class frigate deployed at the Second Battle of Geonosis during the Clone Wars. It was sent to a medical station at Ord Cestus with supplies intended for Jedi General Mace Windu's forces on Dantooine. However, the ship was infested by Geonosian brain worms, which Ahsoka Tano stopped by rupturing the ship's coolant tanks. The ship arrived at Ord Cestus, preventing the crew from freezing to death.
