Mitsubishi Ki-46

The Mitsubishi Ki-46 was a twin-engined reconnaissance plane used by the Japanese Imperial Army in World War II. Its Army designation was "Type 100 Command Reconnaissance Aircraft" (百式司令部偵察機); the Allied code name was "Dinah". This aircraft was first used by the Japanese Army in Manchuria and China, where seven units were equipped with it, and also at times by the Japanese Imperial Navy in certain reconnaissance missions over the north coasts of Australia and New Guinea. Mitsubishi factories made a total of 1,742 examples of all versions (types I-IV) during 1941-44.

The Japanese Army used this aircraft for the same type of missions (which were not authorized) over present-day Malaysia, during the months before the Pacific War. Later it was used over Burma, Indochina and Thailand; and in operations over the Indian Ocean area too.

In 1944-45, during the last days of the war, it was modified as a high altitude interceptor, with two 20 mm cannons in the nose and one 37 mm cannon in an "upwards-and-forwards" position, almost like the Luftwaffe's Schrage Musik night fighter cannon emplacements, for fighting against the USAAF B-29 over the metropolitan Japanese islands. It lacked stability for sustained shooting of the 37 mm weapon, was weak in its armour, and slow to climb.

The Ki-46 was also assigned to two whole Sentai (wings/groups), as well as individual Chutaicho (junior operational commanders) in the Imperial Japanese Army Air Service, during the Pacific War.

The United States captured some examples during conflict for evaluations.
