The Exterminator-class vessel was a type of starship used by the Dalek Empire. The class of vessel was built in the 26th century during a conflict between humanity and the Daleks. Considered the ultimate Dalek space craft, it was armed to the teeth and carried a crew of 500. The first vessel of this class was the Exterminator, which was the flagship of the Dalek fleet and used as the personal ship of the Dalek Inquisitor General, Dalek X. The ship was destroyed by the Tenth Doctor, who detonated the fuel residue in a silo. (PROSE: Prisoner of the Daleks)
