The Tisiphone was a Spacefleet Fury-class fighter. It was an elderly and under-powered ship when it was sent to fight the Daleks at the Battle of Bellatrix in 2547 or 2548. It was badly damaged during the battle; two of its six crew members died and were absorbed by a transdimensional rift that transported it to 1963 Earth. Admiral Isaac Summerfield II, the Tisiphone's commanding officer, took the ship's homing device with him as he and the surviving crew members fled to England. They placed the damaged and anachronistic ship on a collision course with the sun, where it was destroyed. (PROSE: Return of the Living Dad [+]Loading...["Return of the Living Dad (novel)"])
