The Ronis class submarines were built for the Latvian Navy in France in 1925. They were acquired by the Soviets in 1940 following the annexation of Latvia by the Soviet Union. They were scuttled in Liepaja in June 1941 as the Nazis were about to capture the port. The hulls were raised in 1942 and scrapped
Design
The boats were small coastal submarines built to a French design. Ronis means Seal in the Latvian language, Spidola is a character from the Latvian language poem Lāčplēsis
