In the summer of 1936, the IJN called for a design of carrier-borne
bomber which was to succeed the obsolescent type 96 Carrier Bomber.
In answer to the IJN specification, design proposals were submitted
by Mitsubishi, Nakajima and Aichi. The first prototype of Aichi was
a monoplane with elliptical wings inspired by the Heinkek He 70. It
was all metal construction low-winged monoplane with fixed under-
carriage, and was completed in December 1937. The intent of adoption
of the fixed undercarriage was to increase the strength of main wing
on which the dive-brake to restrain the diving speed are fitted.

The first prototype was suffered seriously from instability in the
maneuver, mainly due to excessive performance of speed, climb
and range. The second prototype was extensively modified to
correct these deficiencies. Aproximately, two years after in the
end of 1939, Aichi succedded in getting a contract for the aircraft,
and was named Kyuukyuu Kanbaku, type 99 Carrier Bomber,
Model 11.

Kyuukyuu Kanbaku took part in almost all major IJN carrier
operations in about first one year of the Pacific war. She had
contributed to the IJN military gain in the Indian Ocean when
she could place 85 percent of her bombs on the target.

In the autumn of 1942, an improved version of Kyuukyuu Kanbaku,
model 22 made its debut and began to replace the model 11 in front
-line units. When much advanced fighter, Suisei D4Y1-5 (a comet),
appeared in the combat arena in 1943, the Kyuukyuu Kanbaku was
relegated to land-based units. However, during the last part of
the war, the Kyuukyuu Kanbaku were brought back into the combat
arena for Kamikaze sorties.
