Note: This is a sub-section of Avro.
The Avro Vulcan (officially Hawker Siddeley Vulcan from July 1963) is a jet-powered delta wing strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. 
Aircraft manufacturer A.V. Roe and Company (Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the riskiest option.
