Mitsubishi Ki-1

The Mitsubishi Ki-1, also known as the Army Type 93 Heavy Bomber, was a twin-engine monoplane bomber built by Mitsubishi for the Imperial Japanese Army in the 1930s. Its design drew heavily on the Junkers K 37, a military conversion of the Junkers S 36 that Mitsubishi representatives studied in Sweden in 1931 and whose sole prototype was bought partly with donations raised in Japan. The Ki-1 first flew in August 1932, and 118 were built in two versions between March 1933 and April 1936. It had a low wing, fixed landing gear, twin fins and rudders, and gunners in semi-enclosed nose and dorsal turrets. Already antiquated when it entered service, it flew in Manchukuo and North China during the early stage of the Second Sino-Japanese War, where fighter opposition was light, and it was replaced in 1937 by the Fiat BR.20.
