Skystriker

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

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

The Cybermen attacked before the rocket was ready, however. When the preparations were finished, the Fourth Doctor asked Chief Councillor Tyrum to delay the launch while he rescued Sarah Jane Smith from the beacon.

When Vorus saw 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 redirected the rocket into the Cyber-ship. (TV: Revenge of the Cybermen)
