Kawasaki Ki-32

Kawasaki proposed a 708kW / 950-hp Ha-9-IIb water-cooled engine of its own design in 1936 for the new Ki-32 light bomber, a mid-wing all-metal cantilever monoplane. A wooden mock-up was constructed in the summer of 1936, followed by eight prototypes, the first of which flew in March 1937. There were problems with the engine, and development was protracted, but the Kawasaki design team of Imashi and Ota was rewarded in July 1938 with a production contract.


Its wide-track fixed cantilever undercarriage featured open-sided wheel fairings. Wing and tail surfaces were finely tapered. The two-man crew were accommodated beneath a long raised canopy. Armament comprised one fixed cowling 7.7mm Type 89 machine-gun and another of the same type on a flexible mounting operated by the observer. An internal bomb bay accommodated a 300kg offensive load, supplemented by 150kg of bombs on external racks.


Designated Army Type 98 Light Bomber, the Ki-32 entered service late in 1938 to supplement the Mitsubishi Ki-30.


Apart from prototypes, Kawasaki delivered 846 Ki-32s up to May 1940. They flew with considerable success with seven operational Sentais (groups) in China, where they made many low-level sorties, particularly in the campaigns to capture the cities of Hangchow and Wuchang during 1938-39. They equipped two operational Sen-tais during the fierce fighting over the Khalkin Gol and Nomonhan on the border of Manchuria and Outer Mongolia against Soviet ground and air units in 1939.
Ki-32s were still in the army's first-line inventory when Japan attacked Pearl Harbor, and were prominent in the heavy attacks on Hong Kong which preceded the British surrender of Hong Kong in December 1941, but during 1942 they were nearly all relegated to training duties. The type received the Allied codename Mary. Armament and bombload were identical with that of Ki-30. Like its Mitsubishi contemporary the Ki-32 carried its normal bombload inter-nally in a fuselage bomb bay.
