The Sarancha class is the NATO reporting name for a hydrofoil missile boat built for the Soviet Navy. The Soviet designation was Project 1240 Uragan (Серия 1240 Ураган- Hurricane).

The boat was a very complex design. Unlike previous Soviet hydrofoil boats the Project 1240 had fully submerged foils with propellers mounted on the after set of foils. The boat achieved a speed of 58 knots (107 km/h) and had a heavy armament. It was deemed too large, complex and expensive for series production and only a prototype boat was built.

The MRK-5 (МРК-5) was laid down at the Petrovski plant in Leningrad in 1973 and was on trials until 1977. In 1979, she was transferred to the Black Sea Fleet via Russian inland waterways. She was based in Sevastopol until 1990, when she was decommissioned. In 1992, she was damaged by fire and sunk in shallow water. The wreck was raised and scrapped.
