The was a Japanese light bomber aircraft of World War II. It was a single-engine, two-seat, mid-wing, cantilever monoplane with a fixed tailwheel undercarriage. An internal bomb bay accommodated a 661 lb (300 kg) offensive load, supplemented by 350 lb (150 kg) of bombs on external racks. During the war, it was known by the Allies by the name Mary. ==Design and development== The Ki-32 was developed in response to a May 1936 Imperial Japanese Army specification to replace the Kawasaki Ki-3 light bomber with a completely indigenously designed and built aircraft. Mitsubishi and Kawasaki were requested to build two prototypes each by December 1936. The specification called for a top speed of at 9,800 ft (3,000 meters); normal operating altitude from 6,500 ft to 13,000 ft (2,000 to 4,000 meters), the ability to climb to 9,800 ft (3,000 meters) within 8 minutes and an engine to be selected from the Mitsubishi Ha-6 radial, Nakajima Ha-5 radial, or Kawasaki Ha-9-IIb liquid-cooled inline engines, a normal bomb load of and a maximum of , one forward-firing machine gun and one flexible rearward-firing machine gun, the ability to perform 60-degree dives for dive bombing, and a loaded weight less than . The first Kawasaki prototype flew in March 1937; seven more prototypes were produced. Being very similar in layout and performance, main difference between the Kawasaki Ki-32 and its Mitsubishi Ki-30 rival was in the choice of an engine. The Mitsubishi design used the Nakajima Ha-5 14-cylinder air-cooled radial engine, whereas Kawasaki opted for their own Kawasaki Ha-9-II inline V12 engine. Problems were encountered with the Kawasaki design, particularly with engine cooling, and the Mitsubishi Ki-30 received the production order. In spite of this, the pressing need for more aircraft in the Second Sino-Japanese War, which had started at full scale in July 1937, resulted in the Ki-32's entry into production as well, 12 months behind its rival. Ironically, the number of Ki-32s built was much higher than that of the successful Ki-30. The Ki-32 entered production in 1938, designated Army Type 98 Single-engine Light Bomber, Kawasaki manufactured 854 Ki-32s before production ceased in May 1940.〔 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「Kawasaki Ki-32」の詳細全文を読む スポンサード リンク
