The Avro Vulcan is a jet-powered, tailless, delta-wing, high-altitude, 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 most technically advanced, hence the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles.

Comparison of Vulcan wing designs
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ).
The Dassault Mirage 2000 is among the most successful delta-winged fighter jets, being used by many countries to this day.
Convair made several supersonic deltas. This is an F-106 Delta Dart, a development of their earlier F-102 Delta Dagger
