The Yokosuka Ro-go Ko-gata(YokoSho-shiki Ro-go Ko-gata) was a Japanese reconnaissance floatplane developed during the First World War by the Japanese Navy Arsenal at Yokosuka, and one of the first indigenous Japanese aircraft to enter production. There were 218 of these aircraft built for the Imperial Japanese Navy, which remained in use until 1928. Development and designThe Japanese Navy Arsenal at Yokosuka became involved in aircraft production in 1913, when an aeroplane factory was set up, with its first work being to build several Maurice Farman and Curtiss Seaplanes.[1] It continued to build aircraft under license, including more Farman aircraft and several Short 184 seaplanes, as well as prototypes of several of its own designs.[2] In 1917, Chikuhei Nakajima, chief designer of the Yokosuka Arsenal aircraft factory designed a new reconnaissance floatplane, with a prototype of the new design, powered by a 140 hp (104 kW) Salmson water-cooled radial engine, making its maiden flight early in 1918. Test results were good, and the type was ordered into production as the Ro-go Ko-gata.{{ref label|Note1|a|a}}[3] The Ro-go Ko-gata was a three-bay biplane of wood and fabric construction, with twin main floats and wings that folded backwards for storage. Its crew of two sat in separate, closely spaced cockpits. Initial production aircraft were powered by 200 hp (149 kW) Salmson engines, but the majority of production aircraft were fitted with 200–220 hp (149–164 kW) Mitsubishi-built Hispano-Suiza 8 V-8 engines.[3] A total of 218 aircraft were built in total,[4] 32 by the Yokosuka arsenal, 80 by Aichi and 106 by the Nakajima Aircraft Company, with production continuing until 1924.[5] It was the first locally designed aircraft to be built in large numbers for the Japanese Navy.[3] Operational historyThree of the early aircraft were modified in 1919 for making long-range flights, with one of the cockpits replaced by additional fuel storage, allowing a record flight of 1,300 km (808 mi) to be flown in 11 hours, 35 min on 20 April 1919.[3] The Ro-go Ko-gata, along with licensed built Hansa-Brandenburg W.29s, replaced the obsolete pusher Farmans in Japanese Navy service, remaining in large scale service until 1926, being re-designated Yokosho-Type Reconnaissance Seaplane in 1923.{{ref label|Note2|b|b}} Several were sold for civilian use, and were used to carry air-mail until 1928.[3][6] Units using this aircraft- {{JPN}}
