Valiant (aircraft carrier)
The Valiant was a large flying aircraft carrier used by UNIT during the early 21st century. It contained various rooms including a conference room and many engine corridors.
History
Every detail of it was designed by "Harold Saxon", and it was used for the first Human contact with the Toclafane. (DW: The Sound of Drums)
In the following year in an erased timeline, the Valiant formed the base of operations for the Master. The Jones family (with the exception of Martha Jones, who had escaped) and Captain Jack Harkness were imprisoned on the ship, as was the Doctor. It also held the paradox machine inside the Doctor's TARDIS. When the timeline was erased, the Valiant was the only point in space and time not to revert, instead moving directly through time, due to it being the "eye of the storm", that is, of the paradox machine. (DW: Last of the Time Lords)
During the Sontaran invasion of Earth in 2009, UNIT used the Valiant's turbines to clear the gas created by ATMOS and to shoot the ATMOS factory in order to allow UNIT's troops to enter and fight the Sontarans. (DW: The Poison Sky)
Behind the Scenes
The weapons system used by the Valiant had a similar appearance to the superweapon from the Jathaa sunglider and the Death Star's planetkiller from Star Wars.
