Watanabe K3M3 Type 90-2 ("Pine")

The Mitsubishi K3M2 was a trainer built by Mitsubishi which was used widely in the Imperial Japanese Navy from World War I through the end of World War II in an extremely wide variety of roles, including light transport, liaison aircraft, utility aircraft and occasionally light bomber. The prototype, designated Mitsubishi 4MS1, made its maiden flight in 1930. The aircraft was strut-braced high-wing cabin monoplane, with fixed wide-track landing gear, and was powered by a single 300 hp (220 kW) water-cooled radial piston engine. Pilot and gunner were located in separate open cockpits, with an instructor and two pupils in the enclosed cabin in the fuselage. Later passenger variants seated five passengers in the cabin. The Navy Type 90 Crew Trainer was primarily a land-based aircraft; however, a few were converted with floats for use as seaplanes. The Imperial Japanese Army Air Force had an interest in the aircraft as part of its modernization program, and as a potential supplement to the Nakajima Ki-6. Two examples were acquired and tested, and the airframe was given the designation of Ki-7. One prototype used a 475 hp (350 kW) Mitsubishi Type 92 nine-cylinder air-cooled radial engine and the other a 450 hp (340 kW) Nakajima Kotobuki nine-cylinder air-cooled radial engine. However, the IJAAF opted not to go into production with either version. Production of the K3M for the Navy continued until 1941, and total production of all versions was around 625 aircraft. Its Allied code name was "Pine".
