Ships of the class
S1
ex-Ryaniy (Рьяный = eager) and ex-Sova (Сова = owl); shipyard number: 112) was a Russian torpedo boat destroyer (officially was classified as a torpedo boat at first and later a squadron torpedo boat), which was taken over by the Finns after the Finnish Civil War in 1918. She was sunk as a training target in 1930.
S2
ex-Prozorlivij (Прозорливый = sharp) and ex-Gagara (Gagara = loon) in Russian service. Taken over by the Finns after the Finnish Civil War in 1918. Lost in a storm on 4 October 1925, with the loss of all hands.
S3
ex-Poslushniy (Послушный = obedient) and ex-Korshun (Коршун = Kite) in Russian service; shipyard number: 101) was taken over by the Finns after the Finnish Civil War in 1918. The ship was returned to Soviet Russia in 1922 in accordance to the Tartu peace treaty of 1920. She was scrapped in 1925.
S4
ex-Rezviy (Резвый = frisky) and ex-Voron (Ворон = raven) in Russian service; shipyard number: 109) was taken over by the Finns after the Finnish Civil War in 1918. The ship was returned to Soviet Russia in 1922 in accordance to the Tartu peace treaty of 1920. She was scrapped in 1925.
S5
ex-Podvishniy (Подвижный = mobile) and ex-Albatros (Альбатрос = albatros; shipyard number: 99) was taken over by the Finns after the Finnish Civil War in 1918. She was used as a decoy target during the Continuation War and was anchored at Pellinge. She was scuttled in shallow water (so that the deck still was above the surface) and a large number of anti-aircraft guns were scattered on the nearby islands. In this manner the Finns hoped to lure the Soviet Air Forces to attack the Finnish coastal defence ship Väinämöinen. No aircraft were however sent there.
S6
ex-Torpedo boat № 212 (Миноносец No. 212) was a Russian seagoing torpedo boat (officially was classified as a torpedo boat), which acted as a minesweeper during World War I. She was taken over by the Finns after the Finnish Civil War in 1918 and returned to Soviet Russia in 1922 in accordance to the Tartu peace treaty of 1920. The S6 was not of the same class as the other S-boats, but of the smaller Modified Ussuri class.
