The Bars class were a group of submarines built for the Imperial Russian Navy during World War I. A total of 24 boats were built between 1914 and 1917.

These boats were designed by Ivan Bubnov and based on the preceding Morzh class. The Morzh design was enlarged with more powerful engines and a larger torpedo armament. They were single hulled boats with four internal 18 inch torpedo tubes and 8 external torpedoes in drop collars.

The design had numerous shortcomings, including a lack of internal bulkheads and a slow diving time. Surviving boats were modernized after the Russian Civil War by installing bulkheads, new diesels, pumps and extra torpedo tubes (the external drop collars were removed).

Wreck location is in the Swedish territorial waters to the north-east of Gotska Sandö island, found 10 September 2009.

Wreck found on 28 May 2009 by the Estonian Maritime Museum in the northern part of the Gulf of Finland.
