Komintern was a Soviet light cruiser originally named "Pamiat' Merkuria" ("Memory of Mercury"), a protected cruiser built for the Imperial Russian Navy. She saw service during World War I in the Black Sea and survived the Russian Civil War, although heavily damaged. She was repaired by the Soviet Navy and put into service as a training ship. In 1941 she was reclassified as a minelayer and provided naval gunfire support and transported troops during the sieges of Odessa, Sevastopol, and the Kerch–Feodosiya operation in the winter of 1941–1942. She was damaged beyond repair at Poti by a German air attack on 16 July 1942. Afterwards she was disarmed and hulked. At some point she was towed to the mouth of the Khobi river and sunk there as a breakwater on 10 October 1942.
