In the short time between 1935 and 1945, the RAF progressed from being equipped with biplanes similar to those used in the First World War to flying near transonic piston-engined machines and the first generation of jets. In this well illustrated book, the author examines the designs which were submitted by various manufacturers, both those which succeeded and those which never left the drawing board, with particular emphasis on changes in engines and armament.
