Tachikawa Ki-17

The Ki-9 was originally planned to be manufactured in two versions using the same basic airframe but with different engines for service as either a primary or intermediate trainer. However, when the lower-powered form proved to be unsuitable due a center of gravity issue, design of a new airframe was ordered for the basic trainer version, and it was given the new designation of Ki-17. Compared to the Ki-9, the Ki-17 had equal-span wings, a slimmer fuselage, and a revised tailplane. It was powered by a Hitachi Ha-13a radial engine. The first prototype flew in July 1935. ==Operational history==

The Ki-17 was introduced to service as the Army Type 95-3 Basic Grade Trainer Model A under the former aircraft naming nomenclature system. Tachikawa manufactured 560 Ki-17s between 1936 and 1943, and the type saw service with the Army Air Academy and flight training schools. ==Operators==
