"Turya class" is the NATO reporting name for a class of hydrofoil torpedo boats built for the Soviet Navy and Soviet allies. The Soviet designation was Project 206M.

Design

The Turya class is a derivative of the Shershen-class torpedo boat. A hydroplane was added forward to increase speed. These boats can operate at 40 knots at sea state 4 and 35 knots at sea state 5. A heavier twin 57 mm gun was added aft in response to NATO fast attack craft being fitted with the 76 mm OTO Melara gun. The boats are fitted with a helicopter type dipping sonar aft. The 533mm (21 inch) torpedo tubes can fire either anti-ship or anti-submarine torpedoes. Export boats were not fitted with dipping sonar.
