1976 to 1977, who flew Supermarine Spitfires with 266 Squadron). Post-war use Bomber Command Immediately after the war RAF Wittering, once again, transferred back to Fighter Command in 1946 providing a home to a variety of squadrons operating Spitfires, Mosquitos and Hornets. In 1948, the Station transferred back to Training Command for 2 years before Maintenance Command took responsibility to undertake some significant redevelopment between 1950 and 1952 as the Cold War saw RAF Wittering become a vital part of the United Kingdom's strategic nuclear deterrent under the control of Bomber Command in 1953. The current airfield was created by the merging of RAF Wittering and nearby Collyweston Relief Landing Ground, by the construction of a 1.7-mile runway between them in 1941. Conversion to a Bomber airfield saw the construction of a new concrete runway (slightly to the south of the 1941 runway), taxiways and dispersals (with further H-dispersals and QRA dispersals being added later) that still form the majority of the Station's aircraft operating surfaces. A wide-span Gaydon hangar for the Canberra B2 bombers was constructed along with a new control tower, avionics building and nuclear storage and maintenance facilities. In its new guise as a bomber station, RAF Wittering initially operated Avro Lincolns from 1953 although these were replaced by English Electric Canberras later that year. The first British operational atomic bomb, the Blue Danube, was deployed to RAF Wittering in November 1953. The first V-bombers (the Vickers Valiant, the Handley Page Victor and the Avro Vulcan) were delivered in July 1955. In 1957–58 tests were carried out on the first British hydrogen bomb. This was fitted into the existing Blue Danube casing, and four Valiant bombers flew out of Wittering to Christmas Island in the Pacific, one of them dropping the first device on 15 May 1957 on Operation Grapple. Until January 1969 two squadrons (100 and 139) of Victor B.2 bombers equipped with Blue Steel stand-off missiles were part of the QRA (Quick Reaction Alert) force of the RAF. Two nuclear armed aircraft were permanently on 15 minutes readiness to take off. They were parked within of the westerly runway threshold. In times of higher tension, four bombers could be stationed beside the runway on the ORP (Operational Readiness Platform). If the aircraft were manned they could all be airborne within 30 seconds, a feat often demonstrated at V force stations across the country. Since the
