Japanese Kaidai-class (Type 4) Submarine

The Kaidai IV, or KD4, boats were Japanese fleet submarines developed between the world wars. They formed part of the navy’s effort to build submarines able to operate with a long-range oceanic strategy rather than remain confined to local coastal defense. The boats served into the Second World War, when submarine roles and Allied countermeasures changed rapidly. Three KD4 boats were built, and their identities changed under Japan’s wartime submarine renumbering. They belonged to a sequence of Kaidai designs emphasizing surface endurance and fleet operations. Older boats eventually faced increasing difficulty surviving Allied radar, aircraft, escort vessels, and coordinated anti-submarine searches.
