Cyber-Fleet

The Cyber-Fleet, or Cyber-Armada, (COMIC: Assimilation²) was the space armada of the Cyber-Empire.

A typical Fleet was composed of at least twenty cyber-ships. (AUDIO: Hour of the Cybermen) Fleets were led by Cyber-Flagships commanded by Cyber-Leaders. (COMIC: The Bidding War)

20th century
A fleet of Cyber-ships planned an invasion of Earth in the 1970s, but was destroyed by missiles coordinated with the help of Zoe Heriot. (TV: The Invasion)

In 1988, though it may have done so through time travel, a Cyber-Fleet consisting of thousands of Cyber-Warships came to Earth seeking the Statue of Nemesis. With it, the Cyber-Leader planned to conquer the Earth and make it their base planet as the New Mondas, turning all humans into slaves.

When confronted by the Cybermen, the Seventh Doctor surrendered the Nemesis to them and launched the statue on the rocket-sled to meet with the Fleet as the Leader instructed. When the Nemesis reached the fleet in orbit of the Moon, having understood the Cyber-Leader's instructions and disobeying them, it exploded, destroying the entire Cyber-Fleet. (TV: Silver Nemesis)

In 1992, a fleet hid beneath the Atlantic Ocean and attempted to conquer Earth, but were destroyed by the Sixth Doctor turning the Cybermen's dehydration weapons against them. (AUDIO: Hour of the Cybermen)

Later history
In the 21st century a cyber-invasion fleet composed of smaller ships held in a larger one planned to invade Earth again, the smaller ships homing in on a radio beam. (TV: The Wheel in Space)

Crossing over to the 24th century of a parallel universe, the Cybermen joined their Cyber-Armada with the Borg, forming the Borg-Cyberman Fleet. (COMIC: Assimilation²)

In 2526, the Main Cyber-Fleet stayed far away from Earth as the Cyber-Leader plotted to destroy the planet. After the plot was foiled, (TV: Earthshock) the Cyber-Fleet dispersed. (TV: Time-Flight)

The fleet was possibly destroyed during the Cyber-Wars, with the remnant Cyberman groups scattered across the Mutter's Spiral, forced to use ancient cyber-ships for travel. (TV: Revenge of the Cybermen)
