The Petya class was the NATO reporting name for a class of light frigates designed in the 1950s and built for the Soviet Navy in the 1960s.

They were the first gas turbine-powered ships in the Soviet navy. The role of these ships was anti-submarine warfare in shallow waters. The specification was issued in 1955 and design approved in 1956. The second series of these ships, which received the number Project 159A, was built from 1966 to 1972 and amounted to 29 ships. They replaced the RBU-2500 with the more powerful RBU-6000, installed a second torpedo tube and upgraded the radar system. A total of 56 ships were built in four shipyards.

Displacement was 970 tons under standard load and 1110 tons under full load. The ship's profile saw the mass of the superstructure contained forward of midships with low-profile funnels aft of this. A main mast was set along the aft section of the superstructure. Power was from a CODAG (COmbined Diesel And Gas) arrangement which paired 2 Gas turbines of 30000 horsepower with 1 Diesel unit of 6000 horsepower - providing speeds reaching 32 knots and ranges out to 2000 nautical miles. A three shaft machinery layout was chosen with the central shaft powered by diesel engines for economical cruising and the two wing shafts powered by gas turbines for speed. Gun armament was two twin 76 mm gun turrets which were controlled by a single radar director. Anti-submarine armament consisted of two RBU-6000 anti-submarine rocket launchers and a two launchers for 400 mm anti-submarine torpedoes.

Frigate SKR-94 laid down 25 March 1968 at the Shipyard No.820, Kaliningrad (yard No.197), launched 22 October 1969, commissioned 30 December 1969 and was assigned to the Black Sea Fleet.

12 October 1972 the ship was renamed to Krasnodarsky komsomolets.

Frigate SKR-94 was excluded from the lists of the Black Sea Fleet on 21 July 1983 and transferred to Ethiopia.
