A Cyber-ship was a type of wheel-shaped starship used by the Cybermen. When the Cybermen made an alliance with the Borg, several Cyber-ships were part of a fleet which also included Borg cubes and spheres. (TNG - Assimilation² comic: "Issue 2")
Within the Doctor Who universe, this type of Cyber-ship first appeared in the 2010 episode The Pandorica Opens and later seen at the beginning of A Good Man Goes to War in 2011. These wheel-shaped ships were based on the Cyberman ships seen in 1968's The Invasion.
