Petya class Frigates (1960)

Project 159 class, Strozhevoi Korabl (light escort) Frigates
soviet cold war navy 8 General Purpose Frigates 1948-1970: 54 completed.

One aspect of the Soviet Navy of the cold war, especially early phase in the 1950-60s was the emphasis on mass production, just as in interwar years. Famous examples of the time were the Project 613 Whiskey class submarines, and the Petya class ASW frigates. With 53 built, after the Skoriy class destroyers (70 ships), and Riga (68), they were the third most numerous surface ships in the Sovietsky Flot inventory. The Petya class were rather small and cheaper than the previous Project 42 Sokol (Kola class) Frigates as ASW escorts. With it also came international success, with the first of many escort, leading this old design to be still around today, notably with Vietnam, whereas most in Soviet services were discarded in the late 1980s and 1990s.

Context of Design

Petya I/IA
During the Second World War, Soviet sub-hunters of various designs were widely used in coastal waters of for inland convoy escort. Construction of the 122-bis project, which started in wartime continued during the first post-war ten-year military shipbuilding program of 1945-1955. This was a fairly successful project but also had a number of disadvantages: Low top speed, weak air defense, even for the 1950s. Therefore, research to develop of a new, more powerful, and largee submarine-hunter started, soon receiving the project number 159. However, constant requirements changes in combat capabilities led to a significant increase in displacement. For this new hull, a new, powerful but lightweight power plant in order to reach the high speed was also necessary, especially from 1957 when the US started a new submarine race, entering the nuclear age with USS Nautilus. In the end, some technical advisors well in tune with recent developments in powerplants in the west, suggeted a combined diesel-gas turbine unit as main power plant.

Requirements-based innovations

Gas Turbine to hunt down US SSNs:
The tactical and technical specifications for Project 159 were completed in 1955 and further development entrusted to the Zelenodolsk Design Bureau which chief designer was A.V. Kunakhovich, chief navy observer Captain 2nd Rank N.D. Kondratenko. Its main purpose was solely to fight submarines beyond all other priorities. Work was completed in 1956.
By this time, standard displacement exceeded 900 tons, and due to this, above classification as “large submarine hunter”, but now “patrol ship”. During the design process, for the first time in the world a workable M-2 afterburning gas turbine engine for a ship, rated for 15,000 hp, was successfully tested at YuTZ. This powerplant was adopted but split on a three-shaft arrangement, with the middle one linked to a diesel engine and variable pitch propeller for cruising flexibility, and side shafts to the gas turbine engines, to fixed pitch propellers. At full speed, all three worked together.

Thrusters for agility:
In cruise and harbor, only the middle shaft was in action, while decoupled outer shafts were freely rotating. However this single-shaft caused agility concerns in the confines of harbour and rivers, or when mooring, and it was decided, also for the first time, to install thrusters based on plans for late R-Boote WW2 designs from the East German company Plager. Later, domestically produced systems were installed for serial production. These VR-159 systems were rated for 6000 hp, studied by A.L. Luchansky, and it was presented as a triumph of domestic mechanical engineering at the time.

The first ASW light torpedoes

For the armament, self-defence was entrusted to two twin 76.2-mm AK-726 autocannons, guided by the Fut-B radar. But the innovation came from a bank firing a brand new type of anti-submarine small-sized torpedoes. There was a single five-tube bank of 400-mm torpedo tube installed admidship. More on that below. This was rounded by two pairs of RBU-2500 ASW rocket launchers installed fore and aft.

Construction program

Proyekt 159/159A
The lead ship, Project 159, numbered SKR-1, was built in 1961 at the Yantar shipyard (No. 820) in Kaliningrad. By 1965, the first series of these ships was built, N°19 and went on in Yantar Shipyard in Kaliningrad and Khabarovsk Shipyard (No. 368). Later the design was altered to project 159-A but until May 1966 they were classified as anti-submarine ships.
They were not easy to built due to a number of innovations, as the first gas turbine-powered ships in the Soviet Navy. The role of these ships was anti-submarine warfare in shallow waters and they were similar to the Mirka-class frigates. Some of the ships designed for export replaced the 406 mm torpedo tubes with anti-ship 533 mm (21 in) torpedo tubes. They had above all a comprehensive sonar suite including VDS, also a first. The 54 ships were built in Kaliningrad Yantar shipyard (22, including exports) and Khabarovsk (32 ships, including exports). They were decommissioned in 1989-1992, but export vessels went on in service for much longer.

Hull and general design

The final design displaced 950 tons standard and 1,150 tons full load, and the hull measured 81.8 m (268 ft 4 in) in lenght, 9.2 m (30 ft 2 in) in beam, 2.9 m (9 ft 6 in) draught. The Crew comprised 90 officers and ratings, meaning she was commanded by a Lieutenant. The general layout of the ship was distinguished by exceptional rationalism and thoughtfulness with living quarters more comfortable tan on the Mirka class for example, or even the larger Kola. The GAS antenna was located in a “torpedo-shaped” stationary fairing located under the keel of the ship, made of titanium, another “first” in shipbuilding.

Modifications & variants

On some ships of Project 159, during modernization upgrades, the Turel control radar was installed instead of the outdated Fut-B starting in 1977-79. The lead ship was converted into a test vessel for the anti-ship missile system “Vikhr” (RPK-1). For this, the whole forward armament was removed and a double canister for guided MS-18 launchers and loading system for eight missiles installed. This system was controlled by a special “Sprut” system received target designation for the main sonar or VDS, but also an external source. The 82-R anti-submarine missile weighed 1800 kg, equipped with various payloads, and with a firing range from 10 to 24 km, damage over 1.5 km (up to 500 m per warhead). Subsequently, it was later installed on Project 1123 and Project 1143 ships.

Already during the construction, decision was made to build ships of a second series with the same armament as Project 35 ships, as Project 159-A, were built from 1966 to 1972 in the amount of 23 units. In the west they received the designation Petya-II class. SKR pr.159-A were exported to various countries (7 units), and in addition, a special export project 159-AE (Petya-III class) was developed, which was supplied to India, Syria and Vietnam.
In order to increase the capabilities in detection of underwater targets, it was decided to modernize the ships (Prokect 159-M) by the Zelenodolsk Design Bureau in 1969-71. The nw design aded the towed VDS “Vega” towed array at the stern. In total from 1973 to 1980, 9 Modified Petya-I class were modernized.

Proyekt 159 (Petya I)

Original design introduced in 1961, 19 built 1958-1965. Older open style superstructure, four RBU-2500 ASW-RL prow and stern.

Proyekt 159A (Petya II)

Updated Project 159, 1966. 23 built 1964-1972. Updated engines, same output, improved search radar, variable depth sonar (VDS) inside the hull stern with redesigned bridge superstructure, two RBU-6000 launchers with Burya fire control system, second quintuple torpedo tube at the stern.

Proyekt 159EA (Petya III)

Export variant for Project 159A introduced, 1968. 13 built 1967-1978. Engine output reduced, single triple tube launcher 533mm heavyweight torpedoes. India vessels had four RBU-2500, Vietnam two RBU-6000.

Proyekt 159M (NATO Petya I(mod))

Update program which concerned 9 Project 159 in 1973-1980. New MG-325 Vega sonar system installed aft (new structure at the stern) no stern RBU-2500, MR-302 Rubka radar instead of Fut-M.

Project 159 ship underway in 1973


Despite its modest size, Project 159 ships had good seaworthiness and could operate in rough seas up to force 4. To reduce rocking and rolling, they had pitch stabilizers installed. But their greater avhievement was their long cruising range at economic speed, more than 2000 miles. On trials they also reached with ease 33 knots at full speed knots using the afterburning gas turbine engines alone. However issues were noted with the three-shaft arrangement in economical mode or searching for submarines, the large outer shaft propellers created resistance, caused ribrations, noises and reduced general efficiency. Issues were also found with the titanium-built sonar fairing, protruding a bit too much and thus, damaged when running aground.

In the Sino-Soviet standdown of 1968-69 some of the Petya ships sent in the Amur River area was marred by their overall draft only caused by the fairing, greater than for the Project 56 (Skory) class destroyers. Navigation in the shallows, mouths of rivers was impossible. But overall they received favourable reviews as being superior to equivalent 1,000 to 2,000 tons ships in any navy at the time.

The last of them were withdrawn from the fleet in 1994. The Black Sea SKR-27, while on combat service in the war zone in the Mediterranean, carried out a combat mission to assist the Egyptian armed forces in June 1967 and throughout 1968. The Pacific SKR-23, while on combat service in war zone in the Arabian and Red Seas, carried out a combat mission to assist the Ethiopian armed forces in 1977-78. As of 2023, Vietnam and Azerbaijan still operate the type, with Vietnam operating five ships and Azerbaijan operating a single ship.
