Naval service: Only Som ('Sheath fish') and Shchuka were delivered by rail to Vladivostok in time and became operational in April and November 1905 respectively. The former boat was the most active submarine of the Siberian Flotilla as she covered over 1300 miles during her war patrols. Losos and Sudak transferred to the Black Sea in 1907, the others remained on the Baltic.
Som 23.5.1916 was rammed by Swedish s/s Ingermanland off Olandshaf (Alands) and lost with all hands. Shchuka, Peskar', Sterlyad' and Beluga were under repair at Revel in 1918 where they were sized by Germans 25.2.1918. Losos' and Sudak were captured at Sevastopol by Germans 1.5.1918, later re-captured by British-French troops and scuttled by them in 1919.
