Harushio-class Patrol Submarine

The Harushio-class patrol submarine is a Japanese diesel-electric submarine class operated by the JMSDF. The design is an evolution from the Yūshio-class being slightly larger and with better noise reduction. The Asashio, has been modified to test Air-independent propulsion (AIP). They are succeeded by the Oyashio and Souryuu-class submarines.
