Variants

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.

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.
