Mitsubishi Ki-30

The Mitsubishi Ki-30, the Army Type 97 Light Bomber code-named Ann by the Allies, was a single-engine mid-wing light bomber of the Imperial Japanese Army with stressed-skin construction and a fixed tailwheel undercarriage. It answered a May 1936 specification to replace the Kawasaki Ki-3 with a wholly Japanese design, and was the first Japanese aircraft powered by a modern two-row radial engine. The first prototype flew on 28 February 1937. It fought in China and in the Philippines, was reliable on rough fields, but suffered once unescorted against Allied fighters and became a trainer by the end of 1942. Production totalled 704 including prototypes, and Thailand also flew it.
