Development
After the Far Eastern-Japanese war, the Imperial Navy begun massive fleet reconstruction program which was drafted after extensive studies of the war experience. One of the new emphasis in the building program was construction of submarines. To accompany the smaller coastal-submarines (LPL 1911 g), plans were made to introduce a proper ocean-going submarine as well. As with the coastal type, Far Eastern Empire turned for the help of the American company Electric boat co. for the development of the new submarine. Unlike with the coastal submarine, all units of the ocean-going submarine were to be build in Far Eastern shipyards. The boat were based on the Holland 31A design and it became the standard submarine type of the Far Eastern Imperial Navy.
Characteristics
Double-hull design with the hull separated by flat bulkheads into several compartments. Very similar to contemporary Russian "Narval"-class also based on the Holland-design. Initially these boats were to be powered by two large diesel engines, one per shaft but the lack of suitable engines forced to adopt 4 smaller domestic diesel engines. This led the boats to have somewhat low performance regarding surface speed particularly.
