Sontaran command ship (The Sontaran Stratagem)

A Sontaran command ship of the Tenth Sontaran Battle Fleet was commanded by General Staal. The ship arrived in orbit of Earth to spearhead an invasion that would turn the planet into a cloning world. It was linked to the surface via teleport pods between the ship, the ATMOS factory and the Rattigan Academy. The ship was destroyed by Luke Rattigan, when he activated his atmospheric converter on the bridge.
