Valiant (aircraft carrier)
Valiant was a name given to at least two Human military fighter carriers. One was a large Earthbound flying aircraft carrier used by UNIT during the early 21st century. (DW: The Sound of Drums, The Poison Sky, and others) The other was a space-based fighter carrier from the very late 2190s that patrolled the reaches of the Solar System to prevent incursions by Endosian pirates and other non-Human threats. (BFA: The Nowhere Place)
21st century
Every detail of the 21st century Valiant was designed by "Harold Saxon", and it was used for the first Human contact with the Toclafane. (DW: The Sound of Drums) The Doctor, Martha Jones and Jack Harkness teleported onboard using Jack's Vortex manipulator at the co- ordinates 58.2 North 10.2 East.
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 Leo Jones) 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)
The Valiant was fitted with a mounted energy weapon almost identical to the gun used to destory the Sycorax meaning the technology could have been salvaged from the remains of the Torchwood institute. During the Sontaran invasion of Earth in 2009 Colonel Mace called in the Valiant which was referred to as Hawk Major. The powerful turbines were used to clear the Sontaran's fog away from the ATMOS factory and the energy weapon was used to blast apart the factory, killing many Sontarans. It is unknown if the weapon was installed after the Master's defeat or if Harry Saxon himself had it incorporated into the initial design.
The Valiant was eventually destroyed when the New Dalek Empire attacked Earth following its transportation to the Medusa Cascade. A massive invasion force of Daleks swarmed the ship, destroying it with their laser guns. (DW: The Stolen Earth)
- Over the comms system Jack Harkness heard a soldier reporting that the shields were down which could mean that the Valiant also had some kind of protective force-shield.
Propulsion
The Valiant used what appeared to be large Turbofan engines.
The Valiant seems to be able to rotate these engines to lower itself toward the ground as seen in (DW: The Poison Sky) As it was designed by the Master, it was more advanced than any current Earth vehicle due to the fact that it has been previously mentioned to have had the reverse-engineered Jathaa sunglider technology built into it. As a back-up it could have some alternative form of travel, like Anti-gravity propulsion. All of which allow it to not only hover high in up in the Earth's atmosphere but to move across the globe to any destination deemed necessary.
Weapons
It is unknown what sort of weapons the Valiant utilises, Apart from the reverse-engineered Jathaa Sunglider weapon. It could possibly feature a series of CIWS turrets and short range missiles, but as a United Nations ship it might not as it is stated to be neutral territory (DW: The Sound of Drums)
Behind the scenes
- The Valiant's design was very similar to that of Cloudbase, the headquarters of Spectrum from Captain Scarlet and the Mysterons and to Helicarriers used by the fictional Marvel Comics organization SHIELD. The Valiant's weapon system looks like the one that was salvaged from a Jathaa sunglider and the Death Star's planetkilling weapon system from Star Wars. A similar-looking vessel, commanded by an elite British air corps, also appears in the fantasy film Sky Captain and the World of Tomorrow.
22nd century
Little was known of the design history of the space fighter carrier Valiant. On 16th January 2197, the Doctor and Evelyn Smythe materialized on Valiant. There, they discovered that some of its crewmembers were hearing a mysterious bell, just as they had in the TARDIS. They quickly ran foul of Valiant's captain, Tanya Oswin in trying to investigate the mystery.
