Designed by Short as the KF.1, the prototype was built by Short and delivered to the Japanese Naval Air Force.
Five were built in Japan and at least one saw service in World War II as the Kawanishi H3K1 Type 90-2, a troop and supply transport assigned the code name Belle.
Later models produced by Kawanishi versions had enclosed cockpits and remained active until replaced by H6K2 Type 97 flying boats in 1938-39.
