Design and development
Following licensed production of the Felixstowe F.5 for the Imperial Japanese Navy the company developed an improved version known as the H1H or Navy Type 15. The aircraft was built with three different engine types fitted, the Navy Type 15-I had longer span upper wings and the Navy Type 15-II had four-bladed propellers. The H1H remained in front line naval service through the 1930s.[1]
