Built between 1927 and 1929, this two-seat twin-float sesquiplane was powered by a 224kW Hispano-Suiza engine and could attain a maximum speed of 166km/h. It was intended for shipboard reconnaissance and served with the Japanese navy as the Type 15 Reconnaissance Floatplane (Nakajima E2N1 and E2N2). A totalof 80 was built, many being relegated to training or sold to civil users during the 1930s. Two machines were bought at the outset for civil fishery patrol duties.
