During 1926, in which year Gloucestershire Aircraft changed its name to Gloster Aircraft, the company was approached by the Japanese Nakajima, which (together with Aichi and Mitsubishi) had been asked to submit a design for a new shipboard fighter for the Imperial Japanese Navy. At this time, H P Folland was designing a shipboard fighter as a company venture. Named Gambet, the prototype was of wooden construction and powered by a 420hp Bristol Jupiter VI nine-cylinder radial, armament consisting of two 7.7rnm Vickers guns mounted in troughs in the fuselage sides. This prototype was acquired by Nakajima in July 1927, together with manufacturing rights. After modification by a team led by Takao Yoshida and installation of a 520hp Nakajima built Jupiter VI engine, the Gambet competed against prototypes of indigenous design and was ordered into production in April 1929 as the Navy Type 3 Carrier Fighter (A1N1).
