The Exterminator class was a type of starship that was used by the Dalek Empire.
It was created in the future during a conflict between Humanity and the Dalek race. Considered the ultimate Dalek space craft, it was armed to the teeth and contained five hundred crew members. 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 The Doctor who detonated the fuel residue in a silo. (NSA: Prisoner of the Daleks)
