Skystriker

Skystriker was a rocket developed by Vorus to destroy the Cybermen. It was built on Voga and Vorus hoped that the victory it brought would free the Vogans from the genocidal threat of the Cybermen.

In order to achieve this, Vorus paid Kellman to lure the Cybermen to Nerva Beacon which he planned to destroy with the rocket.

However, when the Cybermen attacked prematurely, the rocket was not ready and when the final preparations were finished, the Fourth Doctor asked the Chief Councillor Tyrum to delay the launch while he rescued Sarah Jane Smith from the beacom.

When Vorus saw that Nerva Beacon was on a collision course with Voga, he launched the rocket, despite having been shot by Tyrum. His dying words were: "my Skystriker, my glory". Following directions from the Doctor, Captain Stevenson was able to redirect the rocket into the cyber-ship. (DW: Revenge of the Cybermen)
