The XK-5 space freighter towers above the Space Defence Station. (TV: The Android Invasion)

The Space Defence Station was a British military base in Devesham. It had offices for UNIT staff such as Brigadier Lethbridge-Stewart. Devesham Control was based out of the station and the first test of the XK-5 space freighter was performed there. Sarah Jane Smith came to Devesham to investigate the death of its pilot, Guy Crayford.

The Kraals created a replica of the Defence Station and the rest of Devesham on Oseidon to rehearse their invasion of Earth and other planets by testing the Kraal androids in an alien environment. It was destroyed when Styggron activated a matter dissolving bomb.

The androids, Styggron travelled aboard the XK-5 to Earth. Guy Crayford, who had not died, but was loyal to Styggron, communicated with the Defence Station as he made his descent and landed there. Several of the station's occupants, including Harry Sullivan, John Benton and Colonel Faraday were replaced with androids. The Fourth Doctor had Grierson, who worked at Devesham Control, realign the station's radar dishes and used them to deactivate the androids. Styggron was killed by his own virus. (TV: The Android Invasion)

Sometime in the early to mid 21st century, the former Defence Station was bought by space tourism billionaire Campbell Irons, who made it the base of operations for the British Rocket Group. (AUDIO: The Feast of Axos)
