Turya-class (Project 206M Shtorm)

The Turya class, designated Project 206M Shtorm by the Soviet Union, is a class of hydrofoil torpedo boats developed as a derivative of the Shershen class. Construction took place between 1972 and 1976 at shipyards in Kolpino and the Ulis yard in Vladivostok.

The design features a forward hydroplane intended to improve performance and maintain speed in various sea states. The armament configuration includes a twin aft gun turret, which was integrated into the design to counter NATO fast attack craft. For underwater detection, the vessels are equipped with a helicopter-type dipping sonar located at the stern, although this system was omitted from export variants. The installed torpedo tubes are capable of launching both anti-ship and anti-submarine torpedoes.

Approximately 51 vessels were completed. The Soviet Navy was the primary operator, receiving the majority of the production run. Following the dissolution of the Soviet Union, three boats remained in service with the Russian Navy’s Caspian Flotilla, and two units were transferred to the Latvian Navy. The class was exported to several Soviet allies between 1979 and 1986. The Cuban Navy acquired nine vessels, and the Vietnamese People's Navy received five. Other international operators have included Cambodia, Ethiopia, and the Seychelles.
