Avro Vulcan RAF strategic ,bomber airplane model. The Avro Vulcan is a jet-powered tailless delta wing high-altitude strategic bomber, which was operated by the Royal Air Force from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced and hence the riskiest option. Several reduced-scale aircraft, designated Avro 707, were produced to test and refine the delta wing design principles.
