Fleet

Fleet was a word often used to describe a group of ships working or travelling together. Fleets were often used in war. Throughout history, fleets had been prevalent on planets as well as in space.

Fleets on planets
In the history of Earth, fleets were used for many purposes, such as war. Since these conflicts took place on a planet, they involved naval ships as opposed to starships. (PROSE: H.M.S. Tardis)

Fleets in space
A star fleet or space fleet was a fleet of starships or other spacecraft. Many space-faring factions, operated in fleets such as the Daleks, (TV: Resurrection of the Daleks) the Cybermen, (TV: Silver Nemesis) and the Sontarans operated in fleets. (TV: The Sontaran Stratagem)

One Dalek, buried on Earth in three parts since the 9th century, sought to contact its fleet when it was brought back to life on 1 January 2019. It knocked out all power across the UK to send its message from the Government Communications Headquarters, but was eventually defeated by the Thirteenth Doctor and her friends. (TV: Resolution)
