War-Wheel

The War-Wheel was a massive battlecruiser used by the Sontarans. The ship looked like an axle with two wheels on its ends. It was armed with a space cannons, carried Sontaran shuttlecraft and was captained by an Admiral.

One War-Wheel was used in the pursuit of a Rutan spy. It moved to every intersecion point where the Rutan might be. (RP: Shakedown: Return of the Sontarans)

Sontaran Commander Steg intended to open a wormhole above Sentarion and send a War-Wheel through it to Ruta III, where it would kill the Rutan Queen. The Doctor closed the wormhole and trapped the War-Wheel inside. (NA: Shakedown)

A War-Wheel was seen in the sky above Stonehenge DW: The Pandorica Opens.
