Mitsubishi 2MR

Another Herbert Smith design, the first example of the Mitsubishi 2MR two-seat carried-based reconnaissance biplane flew in January 1922. The type entered service as the Type 10 Carrier Reconnaissance Biplane and was built in a number of versions. The 2MR1 had a frontal radiator for its 224kW Hispano-Suiza 8 engine, while the 2MR2 had twin underslung Lamblin radiators and redesigned tail surfaces. The 2MR4, which was the main production version, had some further revisions of the wing and tail unit, and other variants with minor changes were the 2MRT1, 2MRT2, 2MRT2A, 2MRT3 and 2MRT3A. Total production of all versions was 159, the last machine leaving the workshops in 1930. After long carrier service, the 2MR was used as a trainer in the late 1930s.

The 2MR4 version spanned 12.04m, had a maximum take-off weight of 1320kg, and was armed with two fixed forward-firing 7.7mm machine-guns, with twin guns of the same calibre mounted over the observer's cockpit, and could carry three 30kg bombs.

The R-2.2 and R-4 civil conversions had an enclosed cabin for two passengers replacing the rear cockpit, and a number of ex-army surplus 2MRs were sold on the civil market in the 1930s.
