Nakajima A2N

The A2N was originally developed as a private venture by Nakajima for the Imperial Japanese Navy. It was based loosely on the Boeing Model 69 and Boeing Model 100, examples of both having been imported in 1928 and 1929 respectively. Takao Yoshida led the design team, and two prototypes, designated Navy Type 90 Carrier Fighter in anticipation of Navy acceptance, were ready by December 1929. Powered by Bristol Jupiter VI engines, these were rejected as not being regarded as offering a significant improvement over the Nakajima A1N. Jingo Kurihara carried out a major redesign, and another prototype, the A2N1, powered by a Nakajima Kotobuki 2, was completed in May 1931. The type was adopted by the Navy in April 1932. ==Operational history==

In 1932, Minoru Genda formed a flight demonstration team known as "Genda's Flying Circus" to promote naval aviation and flew this type. The Navy Type 90 Carrier-based fighter flew from the , and . On what would become the first air battles of the Second Sino-Japanese War-Second World War for the air-combat units of these aircraft carriers, A2N fighter pilot Akio Matsuba from Kaga, flying air-cover in support of Japanese troop-landings in the Battle of Shanghai on 16 August 1937, shot-down a Chinese Air Force Douglas O-2M on an attack mission against Japanese forces in Shanghai. A2Ns were soon completely superseded by the A4Ns and A5Ms fighters. ==Variants==
