The Mitsubishi Army Type 92 Reconnaissance Aircraft (九二式偵察機) (company designation 2MR8) was a Japanese short-range reconnaissance aircraft of the 1930s designed by Mitsubishi for the Imperial Japanese Army Air Force. A total of 230 were built, serving between 1933 and 1936. A parasol monoplane, the Type 92 was the first military aircraft powered by an engine both designed and manufactured in Japan to enter service.
Development and design
[edit]In 1930, Mitsubishi developed two designs to meet a Japanese Army requirement for a short-range reconnaissance aircraft to supplement the larger, long-range Kawasaki Type 88, the 2MR7, a biplane based on its earlier 2MR reconnaissance aircraft and B2M torpedo bomber developed for the Imperial Japanese Navy, and the 2MR8, a high-wing parasol monoplane.[1]
The first of four prototypes flew on 28 March 1931, powered by a 239 kW (320 hp) Mitsubishi A2 radial engine. Successive prototypes were modified with more powerful engines, reduced wing area and a shorter fuselage until the fourth prototype was accepted by the Japanese Army, and ordered into service as the Type 92 Reconnaissance Aircraft.[2]
The production Type 92 had fixed wide-track divided landing gear, and was powered by a 354 kW (450 hp) Mitsubishi Type 92 radial engine. It carried a crew of two in open cockpits, with an armament of two synchronised, forward-firing 7.7 mm (.303 in) machine guns and one or two flexibly-mounted guns on the observer's cockpit. Production completed in 1934 after a total of 230 aircraft were built.[2]
To meet the requirements of the Japanese Ministry of Railways for a survey aircraft, Mitsubishi developed a civilian version of the Type 92, the Hato survey aircraft. A single aircraft was ordered in 1935, together with a Fokker Super Universal built by Nakajima. Powered by a 298 kW (400 hp) Mitsubishi A5 engine, it differed from the military version in having a glazed canopy over the rear cockpit (which accommodated a crew of two), an open forward pilot's cockpit, and spat-type main wheel fairings. It was delivered in March 1936 and registered J-AARA.[3]
Operational history
[edit]The Type 92 saw active service in Manchuria with the air battalions (later expanded to air wings) of the Kwantung Army Air Corps between 1933 and 1936.[4] The Mitsubishi Type 92 was also used by the Chinese Air Force in the early stages of the Second Sino-Japanese War.[5]
Operators
[edit]
- Kwangsi Air Force purchased two Type 92s in September 1934, with a few more being purchased in 1935.[5]
