The Poti class was the NATO reporting name for a group of anti-submarine warfare (ASW) corvettes built for the Soviet Navy. The Soviet designation was Project 204 small anti-submarine ships. These ships were the first Soviet warships powered by gas turbine engines; two propellers were mounted in tunnels to give a very shallow draught. A twin 57 mm (2 in) gun mounting provided self-defence. Three ships of the class were exported to Romania and six to Bulgaria during the Cold War. By 2008, all ships of the class were no longer extant.
