The was a light bomber built by Mitsubishi for the Imperial Japanese Army in the 1930s. Its Allied nickname was "Louise". Despite its antiquated appearance, the Ki-2 was successfully used in Manchukuo and in north China during the early stages of the Second Sino-Japanese War, in areas where danger from enemy fighter aircraft was minimal. It was later used in a training role. ==Design and development== The Ki-2 was a low-wing cantilever monoplane with corrugated metal alloy decking and twin fins and rudders, and had fixed divided landing gear. It was powered by two Nakajima Kotobuki radial engines. Maximum speed was , normal range and maximum take-off weight . Single 7.7 mm (.303 in) machine guns were mounted in a semi-enclosed nose gun turret and a dorsal position, and maximum bomb load was . The Ki-2 was, like its stable mate the Mitsubishi Ki-1, an adaptation of the Junkers S36 first flown in 1927. Militarized into the Junkers K37 by Junker's Swedish subsidiary AB Flygindustri at Limhamn near Malmö in Sweden, it was able to reach altitudes not reachable for the fighter aircraft of 1927. However, as soon as 1930 this advantage was lost due to British developments such as the Bristol Bulldog fighter, and Junkers was not successful in selling the design. However, in 1931, representatives of the Mitsubishi Nainenki K.K. in Japan visited the Limhamn facilities to study some of the military conversions of Junkers aircraft, and purchased the sole K37 prototype S-AABP (ex D-1252 S36-prototype) as well as all development papers and a signed a contract for licensed production. The K37 prototype was brought to Japan and tested in combat in the Manchurian Incident of 1931, following which the Imperial Japanese Army Air Force authorized Mitsubishi to produce both heavy and light bomber variations. The heavy bomber version, the Ki-1, was much larger than the original Junkers K37 and first flew in August 1932. The light bomber version, the Mitsubishi Ki-2, was about the same size and weight as the K37 prototype. It flew for the first time in May 1933. While the fuselage was redesigned by Mitsubishi, the wings were kept largely unchanged, except for additional ailerons. Mitsubishi built total of 113 aircraft and an additional 13 aircraft built by Kawasaki Kōkūki Kōgyō KK from 1933-1936. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mitsubishi Ki-2」の詳細全文を読む スポンサード リンク
