Usio's S-Boot. S15 was a 1934 S Boot commissioned early 1937. Only four boats of this type were built, and because of their bad stability and light armament, they were not used as active fast attack boats, but as fast submarine hunters from autumn 1940. S15 was taken over by the USA after the war, given to Denmark in July 1947 where it was broken up.
