KI-1

The Mitsubishi Ki-1, also known as Mitsubishi Army Type 93 Heavy Bomber, was a bomber built by Mitsubishi for the Imperial Japanese Army in the 1930s. The Ki-1 design was heavily based on the Junkers K 37, and the prototype flew in the early 1930s. 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.
