The Mitsubishi Ki-1, also known as Mitsubishi Army Type 93 Heavy Bomber, was a bomber for the Imperial Japanese Army in the 1930s.
The Ki-1 design was heavily based on the Junkers K 37 and a mockup was ready in August 1932, with the first prototype being finished in March 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, in areas where danger from enemy fighter aircraft was minimal.
