The Mukha class, Soviet designation Project 11451 Sokol (falcon), was a class of hydrofoil patrol corvettes built for the Soviet Navy. Designated with the NATO reporting name Mukha class, it consisted of anti-submarine hydrofoils, used primarily for experimental purposes.[1]
From a technical point of view, it is a modified version of the previous Babochka class (Project 1141), with which it shares the same hull and propulsion system. In particular, propulsion with the hull out of the water (foilborne) is ensured by two M-10 (NK-12M) gas turbines of 36,000 shp + 2 M-16 GTU, which allow a maximum speed of 50 knots, while propulsion with the hull in the water (hullborne) is ensured by two M-401 diesel engines of 2,200 shp (12.2 knots maximum speed). At the time of construction, no missile armament was carried, even if these units later received systems of various types. In detail, both SA-N-8 anti-aircraft missiles and SS-N-29anti-ship missile mounted. Sources also diverge on the shipyard where the construction took place.
Service
The two vessels entered service in the second half of the 1980s with the Black Sea Fleet. Future production was canceled, and the ships were used only for experimental purposes. In particular, one vessel was used for testing the SS-N-29 anti-ship missile, which lasted from 1993 to 1997.
Only one unit, designated MPK-220 Vladimirets, was still in service with the Russian Navy as of October 2001, decommissioned in 2014.
Ships
A total of 4 boats were planned for the Soviet Navy, but only two were completed.
