Sovershenny (Совершенный) was one of 18 Storozhevoy-class destroyer (officially known as Project 7U) built for the Soviet Navy during the late 1930s. Although she began construction as a Project 7 Gnevny-class destroyer, Sovershenny was completed in 1941 to the modified Project 7U design. The ship struck a mine while running her acceptance trials in September. While under repair in November, she was hit by two bombs that virtually wrecked her; the Soviets subsequently disarmed her. Repairs resumed in early 1942 until Sovershenny was sunk by an artillery shell in June. Her wreck was scrapped in late 1945.
