The Yurka class were a group of minesweepers built for the Soviet Navy and export customers between 1963 and 1970. The Soviet designation was Project 266 Aquamarine. A new seagoing minesweeper design was requested in 1957 to follow the T43 class minesweeper into the Soviet Navy. The design was approved in 1959 and entered service in 1963. Major improvements in mine detection and anti mine explosion protection were implemented. Magnetic, acoustic and electric signatures were reduced.

The hull was built of low magnetic steel, and was divided into nine water-tight compartments. The artillery weapons of the ship consisted of two 30-mm AK-230 guns. The power plant of the ship consisted of 2 diesel engines of 500 hp and two adjustable pitch screws. The minesweeper's full speed was 16 knots and up to 14 knots with one sweep. From 1964 to 1970 there were built more then 40 minesweepers.
