The KDA-5 was designed by Richard Vogt to meet a Japanese Army requirement for a fighter biplane.
[1] The aircraft had unequal-span sesquiplane wings and fixed tailwheel landing gear and was powered by a 470 kW (630 hp) BMW VI engine.
After 180 aircraft were built, production continued with a structurally strengthened and more powerful Type 92 Model 2.
[1] Both versions saw action with the Imperial Japanese Army Air Force in Manchukuo (Manchuria), although it proved unpopular owing to its unstable take-off and landing behaviour and being difficult to maintain, particularly in cold weather.
