Gallifreyan Cyber Fleet

The Gallifreyan Cyber Fleet was the fleet of dozens of Cyber-ships formed by the alliance between Rassilon and the Cybermen near the end of the universe. After Rassilon was overthrown as Lord President, he encountered the Cybermen, powerful but without a leader, and joined with the Cyberiad. Together, the fleet returned on Gallifrey and gained jurisdiction over the planet. (COMIC: Supremacy of the Cybermen)
