The Kaichu type submarines were double-hulled medium sized submarines of the Imperial Japanese Navy during World War II. They were derived from the Kaigun-shiki Tyuugata (海軍式中型?) submarine (KT).
Several variants existed. From 1934 to 1944, the K6 type (RO-33 Class) and the K7 type (Sentyuu, RO-35 Class) were built. They were equipped with a 3.25 inch (80 mm) gun and 4 x 53cm Type 95 Long Lance torpedoes.
Most of these submarines were destroyed in combat, suffering from Allied Anti-Submarine Warfare measures, and only RO-50 survived the war.
