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. (HOMEVID: 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 Seventh Doctor closed the wormhole and trapped the War-Wheel inside. (PROSE: Shakedown)

Behind the scenes

 * The War-Wheel resembles the ships of the Cyberman fleet seen in TV: The Invasion, of which a homage design appeared in TV: The Pandorica Opens and A Good Man Goes to War, with the former appearance being alongside a Sontaran flagship.
