The Mirka class was the NATO reporting name for a class of light frigates built for the Soviet Navy in the mid to late 1960s. The Soviet designation was Storozhevoi Korabl (escort ship) Project 35 (Mirka I) and Project 35M (Mirka II).

The role of these ships was anti-submarine warfare in shallow waters and they were similar to the Petya-class frigates but had a modified machinery suite. The machinery consisted of two shafts with diesels and gas turbines (CODAG). The propellers were in tunnels (similar to water jets). The machinery proved noisy and not very reliable.^{[citation needed]}

A total of 18 ships were built by Yantar shipyard, Kaliningrad, for the Soviet Navy. All ships were decommissioned between 1989 and 1992.^{[citation needed]}
