“The Mitsubishi Ki-1 was a bomber built by Mitsubishi for the Imperial Japanese Army in the 1930s. The Mitsubishi Ki-1 flew for the first time in 1933. Despite its antiquated appearance, the Ki-1 was used in Manchukuo and in north China during the early stages of the Second Sino-Japanese War. The Mitsubishi Ki-1 was initially designated Army Type 93-1 Heavy Bomber under the former aircraft nomenclature system used by the Japanese military. Already obsolete by the time of its introduction, it found use during the counterinsurgency operations of the Pacification of Manchukuo, and as well as limited use during the Second Sino-Japanese War.

“The Mitsubishi Ki-1 was a low-wing, cantilever monoplane with fixed landing gear, twin fins and rudders. The pilot and co-pilot were seated in tandem under an enclosed canopy, while gunners sat in semi-enclosed nose and dorsal gun turrets. The Ki-1 shared a similar configuration with the Junkers S36/K37 first flown in 1927, but the Ki-1 itself shared nothing whatsoever with the German design other than a similar appearance. A total of 118 aircraft were built in two versions between March 1933 and April 1936.

“Eventually Italian-made Fiat BR.20 bombers were procured as a stopgap until the Mitsubishi Ki-21 could be produced in sufficient numbers to replace the Ki-1. By 1938 the type had been withdrawn entirely from front line service.”
