The Rikugun Kogiken Plan III Light Bomber was a Japanese military aircraft project during World War II. Developed under the Imperial Japanese Army Air Service, this light bomber was part of an effort to enhance Japan's aerial capabilities. The design aimed to balance speed, maneuverability, and payload capacity, enabling it to perform bombing missions with greater efficiency. Despite the advanced planning and engineering efforts, the aircraft did not reach mass production, largely due to the shifting priorities and resource constraints experienced by Japan in the later stages of the war. The Rikugun Kogiken Plan III remains a notable example of Japan's ambitious military aviation projects during this era.
