The Kawasaki KDA-3 was a single-engine, parasol wing, single seat experimental fighter aircraft designed by Dornier engineer Dr. Richard Vogt and built by Kawasaki for the Japanese Imperial Army, first flying in 1928.

In March 1927, the Rikugun Koku Hombu, or the Technical Branch of the Imperial Army Air Headquarters, ordered Kawasaki, Nakajima, and Mitsubishi to investigate design of a single-seat fighter on a competitive basis to replace the aging Ko-4 (Nieuport-Delage NiD 29).

He and his assistant engineer and primary student, Kawasaki's Takeo Doi, used the high-wing German Dornier Do H as the starting point for the KDA-3 design.

The Rikugun Koku Hombu suspended evaluation of the contending types, canceled the program and began testing the other prototypes to destruction.

The Imperial Japanese Army began turning to nationalism the same year, and before long, a decision was made at the highest level to no longer purchase aircraft that were not designed and built in Japan, and to no longer hire foreign engineers or designers.
