Note
1. Conway’s All the world’s Fighting Ships 1922-1946 mentioned the launching in 1936 of the Sinsamudar-class consting of the Blajunpol, Machanu, Sinsamudar and the Vilun all launched in 1936 at the Japanese shipyard of Mitsubuishi, Kobe, Japan and which served until 1950. These were however not the submarines mentioned in the note but the four small coastal submarines built in 1938.
