Ukrainian Corvette Kahovka

The Matka class is the NATO reporting name for a group of hydrofoil missile boats built for the Soviet Navy. The Soviet designation is Project 206MR Vikhr.
These boats are the descendants of the Osa-class missile boat and are a heavily modified version of the Turya-class torpedo boat. There is only a single foil, the aft part of the hull hydroplanes at high speeds. They are air-conditioned and NBC-sealed. The SS-N-2 launchers are the same type as carried on the Project 61MR (“Mod-Kashin“)-class destroyers. Despite initial reports that they were good seaboats, later information revealed that the Soviets regarded them as cramped inside and top-heavy. Of thirteen planned ships, one was cancelled and another started but never completed. All were built in Leningrad.
After the breakup of the USSR, Russia discarded many and five went to Ukraine, one of which was later transferred to Georgia after a complete refurbishment.
