The Asashio-class submarine is a submarine class of Japanese Maritime Self-Defense Force comprising four boats. This class is the successor of Ōshio. The class were the first fleet submarines constructed for post-war Japan. The first submarine was authorized as part of the 1963 shipbuilding programme. Their design improved on previous Japanese classes by being larger to obtain better seaworthiness with greater torpedo stowage. The class entered service in the late 1960s and remained as such until the mid-1980s when they were taken out of service.
