Spacefleet
The Spacefleet was a human based organisation which existed from the early 26th century until (and most likely after) the Earth Empire's fall in the 30th century. (NA: Love and War, Original Sin)
The Spacefleet's most notable presence was combating the Daleks during the Second Dalek War.
The Spacefleet operated a number of facilities including boarding schools for children of members of the Spacefleet, one such school was operated on Mal Oreille (BFBS:Missing Adventures: Biology Lesson on Mal Oreille).
In 2547 Admiral Isaac Summerfield and a fleet of ships encountered a Dalek fleet and fought at Bellatrix, in destroying the Daleks the Admiral's ship the Tisiphone fell into a sacio-temporal rift, taking it back to 1963, Earth. (NA: Return of the Living Dad)
Following her father's apparent disappearance (and death) and escaping foster families, Bernice Summerfield was placed within the Spacefleet military academy. Where she showed an aptitude for the life of a soldier within the Spacefleet, and might have made Section Leader, had it not been for her disciplinary record. (NA: Love and War, BFBS: Missing Adventures: The Tunnels to Heaven) She escaped from the Spacefleet by bailing out of a troop ship in an escape pod on route to Capella.
