- You may be looking for Cyber Ships which made up the Twelfth Cyber Legion.
A Cyber-ship was a craft used by Cybermen. A group of Cybermen used one such craft when they journeyed to Nerva Beacon. While in flight, they maintained contact with their human agent, Kellman, through radio communications.
After setting the beacon on a collision course with Voga, the Cybermen left in the ship. Commander Stevenson, following the Fourth Doctor's directions, redirected the rocket Skystriker into the craft, destroying it. (TV: Revenge of the Cybermen)
