Project history: The first combat submarine ordered by the Imperial Russian Navy in July 1901 to the design of the engineer Bubnov. A single hull type with saddle tanks, the outer plating was covered with teak to prevent damage when grounding. When completed in 1904 she carried a number instead of a name, being officially rated as a torpedo-boat. The first trials discovered faulty venting in the ballast tanks and diving took 12 minutes.
Modernizations: 1910s: superstructure was reconstructed; - 2 - 381 TC; + 1 x 1 - 7.6/94, 2 - 450 TC
Naval service: While doing a practice dive she sank accidentally in the Neva on 29 June 1904 (21 lives lost, 11 survivors) but was raised four days later and transferred to Valdivostok in November 1904, becoming operational in February 1905. Once again sunk by an explosion of petrol vapours in May 1905 she was recommissioned after the conclusion of hostilities against Japan. Transferred to the Arctic in October 1916 but proved unsuitable for modern warfare and was deleted in September 1917.
