Kaichu type submarine

The Kaichu type submarines were double-hulled medium sized submarines of the Imperial Japanese Navy during World War II. They were derived from the nihongo|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 four 53 cm torpedo tubes for ten 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.
