The ship's reactor housing was shattered but the reactor itself shut down.

The ship deactivated after all the Cybermen were destroyed. (PROSE: Plague of the Cybermen)

Several Cyber Ships took part in the Siege of Trenzalore in an attempt to break through the force field put around the planet by the Papal Mainframe. The Cybermen made their own attempt to break the Siege including sending in a low-tech wooden Cyberman to Trenzalore but the Doctor stopped them. When the Daleks attacked the Mainframe and learned how to break the force field, the Cybermen followed in their wake and took part in the fighting that followed. They either all died or retreated in their ships over the course of the battle. (TV: The Time of the Doctor)
