to design these aircraft. Smith's design for a reconnaissance aircraft, designated by Mitsubishi the 2MR, first flew on 12 January 1922. The 2MR was of similar layout to the contemporary 1MF fighter (i.e. a single-bay wooden biplane), but scaled up to accommodate a two-man crew, and was powered by a similar license-built Hispano-Suiza engine. After successful testing, the 2MR was adopted by the Japanese Navy as the Navy Type 10 Carrier Reconnaissance Aircraft (Type 10 referring to the year of ordering of 1921, the tenth year of the Taishō period), with production continuing until 1930, a total of 159 being built.

Operational history

The biplane series of the 2MR continued in service aboard Japan's aircraft carriers through the 1920s and into the 1930s, with versions being used as intermediate trainers until the late-1930s. Many were converted to civil use, being used both as trainers and for communications purposes for newspaper companies. Some remained in civilian service until 1938.
