The Vickers VC.1 Viking was a British twin-engine short-range airliner derived from the Vickers Wellington bomber and built by Vickers-Armstrongs Limited at Brooklands near Weybridge in Surrey. After the Second World War, the Viking was an important airliner with British airlines, pending the development of turboprop aircraft like the Viscount. The Valetta was a military derivative of the Viking developed in transport and training variants for the Royal Air Force, while the Varsity was a versatile twin piston-engined aircraft developed from the Viking and Valetta but with a tricycle undercarriage and ventral pannier for bomb-aimer training, among other changes. It was brought into RAF service in 1951 for crew training as a replacement for the Wellington T.10.
