The Avro Vulcan was a British delta-wing military bomber and one of the RAF’s three V-bomber types. Developed for the nuclear deterrent, it later served in conventional bombing roles and participated in the 1982 Falklands campaign.[1]
Delta-wing development
Avro investigated the delta-wing concept with the smaller 707 research aircraft before the Vulcan prototype flew on 30 August 1952. The large wing supported a combination of load carrying, high-subsonic speed and long-range flight. The first production Vulcan flew in February 1955, and the type entered service with No. 230 Operational Conversion Unit at Waddington in 1956.[2]
The larger B.2
The improved B.2 entered service in July 1960 and had a larger wing than the original B.1. Its increased performance supported adaptation to carry Blue Steel, a nuclear stand-off weapon intended to permit release outside a target’s immediate missile defences. This represented a change from relying entirely on flying over the target with a free-fall weapon.[2][1]
Changing operational roles
Improved Soviet missile defences prompted a switch from high-altitude penetration to low-level operations during the 1960s. The Royal Navy’s Polaris submarines assumed the strategic deterrent responsibility in 1969. Vulcans retained a tactical nuclear role with WE177 bombs alongside their conventional bombing duties supporting NATO forces in Europe.[3][1]
Falklands service and retirement
In-flight refuelling enabled Vulcans to operate from Ascension Island against targets in the Falklands in 1982. The missions required extensive tanker support over a long ocean route. Aircraft XM598 was the primary bomber for Black Buck 1 but turned back after a cockpit window failed to seal, preventing pressurisation. A reserve aircraft continued the mission. Operational Vulcan service ended in 1984.[4][1]
