"Thunderball" is a 1965 British spy film and the fourth in the James Bond series produced by Eon Productions, starring Sean Connery as the fictional MI6 agent James Bond. It is an adaptation of the 1961 novel of the same name by Ian Fleming, which in turn was based on an original story by Kevin McClory, Jack Whittingham, and Fleming. It was the third and final Bond film to be directed by Terence Young, with its screenplay by Richard Maibaum and John Hopkins.

The film follows Bond's mission to find two NATO atomic bombs stolen by SPECTRE operative Emilio Largo after hijacking the two atomic bombs from a Royal Air Force (RAF) Avro Vulcan strategic jet bomber during a training exercise. They then hold the world for ransom of £100 million in diamonds under its threat to destroy an unspecified metropolis in either the United Kingdom or the United States (later revealed to be Miami).

The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) 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.
