Valiant (aircraft carrier)
From Tardis Wiki, the free Doctor Who reference
The Valiant is a flying aircraft carrier used by UNIT. It is very large and contains various rooms including a conference room and many engine corridors. It is kept secret from public knowledge but officials such as the President of the USA and the Prime Minister know of it. It may have been built using alien technology. It is unknown how old it is or how many similar craft there are.
It was used for the first human contact with the Toclafane. (DW: The Sound of Drums)
