Dreadnought-class ship

A Dreadnoughtclass ship was a class of ships used to front a Cyberman invasion.

It was a massive Cyberman-shaped giant capable of walking. It contained an energy weapon in its left hand and a missile launcher in its right. Inside its chest was a factory for Cyber-conversion. The mouthpiece also acted as an observation deck where the controlling Cyber unit would be stationed. One such vessel was the CyberKing. (TV: The Next Doctor)

At least three Dreadnoughts led a full-scale Cyberman invasion of Sontar, their firepower overwhelming even the Sontarans' defences. (COMIC: Supremacy of the Cybermen)
