The Kawasaki Ki-32 (Army Type 98 Single-engined Light Bomber) was the
Japanese
Army’s primary light
bomber from 1938 to 1940, having demonstrated better flying
characteristics than
the rival Ki-30,
and it was produced in
larger numbers. The design dated from May 1936, when the Japanese Army
instructed Kawasaki to design a replacement for the Ki-3 light bomber,
and the first prototype flew in March 1937. There were serious teething
difficulties with the liquid-cooled Ha-9 engine, but the Japanese Army
was now fully engaged in China and
needed all the aircraft it could get, and "Mary" went into production
in July 1938. At that time its performance was the equal of its
counterparts in the West and helped bring the Japanese Army Air Force
into parity with the Western powers.
"Mary" was the last Army bomber to use a
liquid-cooled engine, which proved vulnerable to battle damage, and
its performance was limited somewhat by its fixed undercarriage. Bombs
were carried in an internal bay. "Mary's" last major
combat action was at Hong
Kong in 1941, where fighter
opposition and antiaircraft
defenses were almost
nonexistent. Thereafter it was used for training.
