Former Latvian Ronis and Spidola. Ordered in France under design of Simoneaut. Single-hulled submarines with traditional for French submarines arrangement of TTs: 2 fixed in a bow of a pressure hull and 2 twin trained on deck, out of a pressure hull (thanks to protective boards they entered into light hull lines). Trained deck TTs can be reloaded only in base.     With occurrence of Latvia into the USSR 19.8.1940 both entered Red Navy, but at once have been put into repair and never been maintained by Soviet crews.
