The was a prototype low-wing monoplane fighter developed for the Imperial Japanese Army Air Force. Its maiden flight took place in February 1934, but it never proceeded to mass production. This model marked the final Japanese project overseen by Richard Vogt prior to his departure back to Germany.
Design and development
Kawasaki Kōkūki Kōgyō K.K. engineered the Ki-5 in response to the Japanese army’s demand for a high-performance fighter to succeed the Type 92. Notably, it was Japan’s inaugural all-metal cantilever monoplane fighter. The aircraft’s design was built around the Kawasaki Ha-9 engine, a domestically produced version of the BMW IX engine, delivering . Its inverted gull wing configuration aimed to improve pilot sightlines and permitted a compact, straightforward landing gear arrangement.
During flight trials, the Ki-5 exhibited major stability and handling deficiencies. Pilots experienced difficulty controlling the aircraft, and the powerplant did not achieve the anticipated maximum speed of .
After manufacturing four prototypes, the program was terminated on 9 September 1934. Despite its flaws, insights gained from the Ki-5 contributed to the development of subsequent Kawasaki fighters such as the Ki-28, Ki-60, and Ki-61.
