The Orfey-class destroyers were built for the Baltic Fleet of the Imperial Russian Navy. They were modified versions of the earlier destroyer Novik and the Derzky-class destroyers. These ships were larger, had triple torpedo tubes and an extra 102 mm (4 in) gun. One ship, Engels, was fitted with a 305 mm (12 in) recoilless rifle for testing in 1934. Eight ships were completed during World War I, one of which was sunk during the Battle of Kassar Wiek. One ship fought against the Allied intervention in the Russian Civil War.

Two ships were scrapped after the Russian Civil War; the five survivors participated in World War II.
