Smetlivy () was one of 29 s (officially known as Project 7) built for the Soviet Navy during the late 1930s. Completed in 1938, she was assigned to the Baltic Fleet and played a minor role in the 1939–1940 Winter War against Finland. After the start of the German invasion of the Soviet Union (Operation Barbarossa) in June 1941, the ship participated in the Gulf of Riga Campaign before withdrawing to Tallinn, Estonia. "Smetlivy" supported Soviet forces during the defense of Tallinn in August and covered the subsequent evacuation to Leningrad. The ship provided naval gunfire support to the defenders of Leningrad over the next several months before she was assigned to evacuate Soviet troops from their enclave in Hanko, Finland, in November. "Smetlivy" struck several mines returning from Hanko and sank with heavy loss of life.
