The Narval class were a group of submarines built for the Imperial Russian Navy. They were designed by the Electric Boat Company and ordered in the 1911 programme as the "Holland 31A" design. The Narval class had advanced features including watertight bulkheads, a crash diving tank and gravitationally filled ballast tanks which did not feature in contemporary Russian-designed boats. The boats were well regarded by the Russian Navy and served in the Black Sea Fleet during World War I, during which they sank 8 merchant ships and 74 coastal vessels.

In 1918 the submarines were subsumed into the Ukrainian State Navy.


Three submarines were built by Nikolayev Dockyard.
