Truncheon, a Lambda-class shuttle, was part of the starship contingent of the Imperial Star Destroyer Ultimatum. In 11 BBY, this vessel was under the temporary authority of Imperial captain Rae Sloane. This shuttle was the transport used by Count Denetrius Vidian while he conducted an inspection of the planet Gorse. Sloane and Vidian utilized Truncheon for their visit to the Moonglow Polychemical facility. The craft met its end when it was destroyed by the rebel Skelly. Skelly sought retribution for the grievous wounds Vidian had inflicted upon him when Skelly attempted to alert Vidian to the structural risks that thorilide mining posed to Gorse's moon, Cynda. Consequently, Vidian and Sloane were compelled to travel to the Imperial spaceport in Highground to acquire a replacement shuttle.
