Mitsubishi Experimental Taka-type Carrier Fighter (1MF9)

The Mitsubishi Experimental Taka-type Carrier Fighter (1MF9) was the first carrier fighter to be designed by a Japanese engineer, but failed to gain a production order.

In April 1926 the Japanese Navy asked Aichi, Mitsubishi and Nakajima to design a new fighter to replace the Mitsubishi Type 10 Carrier Fighter. The new aircraft had to have a watertight fuselage, a boat-shaped lower hull and a watertight tight lower wing, improving its ability to float if it was forced to land on the water.

The 1MF9 was designed by Joji Hattori, a designer who had worked under Herbert Smith on the Type 10. He produced a single-span biplane with a fabric covered wooden structure. It was powered by a Mitsubishi Type Hi twelve-cylinder vee water cooled engine and was armed with two fixed forward firing machine guns. The undercarriage could be jettisoned as could the fuel, both features that were intended to improve the aircraft's ability to ditch. The first prototype had flaps, and the 1MF9 was the first Japanese fighter to use split flaps.

The 1MF9 came up against the Aichi HD 23 (designed by Heinkel) while Nakajima submitted a modified version of the light-weight Gloster Gamecock Gambet. This last aircraft didn't have any of the special ditching features requested by the navy, but it was 1,000lb lighter and more manoeuvrable. The Nakajima aircraft was accepted for production as the A1N1 Navy Type 3 Carrier Fighter.
