The Opytny was a Soviet Project 45-class destroyer. She was the only Project 45 ship built, and the first indigenously designed Soviet destroyer. Opytny was laid down on 26th June 1935 and commissioned on 11th September 1941. Originally she was named Sergo Ordzhonikidze, but was subsequently renamed Opytny in 1940. Due to issues with her boilers, she was not suited for fleet operations, but the German attack on the Soviet Union caused her to be accepted into service. She was assigned to the Baltic Fleet and saw a limited career as a floating battery during the Siege of Leningrad. She was taken out of service in March 1944 and scrapped in 1953.

Opytny was introduced in Update "Kings of Battle". As the main armament is manually driven, the turrets suffer from poor traverse speed rendering these difficult when switching targets. The guns itself are also protected only by 13 mm thick antifragmentation armour covering sides, front and top side. As with most destroyers from other navies as well, Opytny features unarmoured magazines above waterline, which will lead to fatal explosion when hit. Unlike the Project 7 class, the propulsion elements are split in pairs, so a single hit cannot completely immobilize the ship.
