Waddington's current runways were put down between 1953 (when the airfield closed) and 1955. The airfield then received two Canberra Squadrons (21 & 27) - the Ops block and other supporting infrastructure went in at the same time as the runway was lengthened. The Vulcan OCU, 230, arrived at Waddington in May 1955 with the first Vulcan landing for contractor's trials work in March 1956. 230 OCU received its first Vulcans proper in January 1957 with 83 Sqn standing up in May 57. The final Canberra Sqn disbanded in June 57.
