The Project 206M Shtorm is a late Cold War era large torpedo boat of Soviet origin. It was one of the last torpedo boats designed. In the West the Project 206M is known by NATO reproting name Turya class.

The Project 206M is a further development of the Project 206 (Shershen) class. The Project 206M improves on maneuverability by adding a hydrofoil, firepower is increased by adding a radar operated 57mm gun turret and its size improves its seagoing capability. The large gun turret is located at the rear in order to keep the bow as light as possible. Two torpedo tubes are fitted on either side of the superstructure.

The primary armament consists of four 533mm torpedo tubes without reloads. The four torpedoes that are carried are either a combination of two 53-56V or VA and two 53-65K, or four USET-80 multipurpose wire guided torpedoes. Air and surface targets can be engaged by the manually operated 25mm 2M-3M gun turret on the bow or the 57mm AK-725 dual purpose gun on the stern. Additionally 10 depth charges are carried.

The Project 206M features a limited sensor suite that consists of the MG-329 Sheksna sonar, MR-103 Bars fire control radar for the 57mm gun and a surfrace search and navigation radar.

As required by its role the Project 206M emphisizes on speed. The three diesel engines provide up to 15.000 hp. This is enough to reach a speed of 44 kt. At 37 kt the range 600 nm, while at lower speeds increases significantly. The Project 206M is meant for green water operations, but has adequate sea going capacities and a 5 day endurance.

The first 24 units that were produced were adopted by the USSR, the following 16 were exported to nations with close ties to the USSR. When the USSR dissolved in 1991 the remaining ships were inherited by Russia.
