The Izyaslav class were a class of destroyers built for the Baltic Fleet of the Imperial Russian Navy. They were modified versions of the Orfey class built in Russia with the assistance of the French company Augustin Normand. These ships fought in World War I, the Russian Civil War, the Estonian War of Independence, and World War II.

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. Fourteen ships were completed in 1914–1917 and fought in World War I and during the Allied intervention in the Russian Civil War. The survivors fought in World War II.
