Krivak class frigates (1970)

The Krivak class were born under the Soviet designation Project 1135 Burevestnik (“storm petrel”) as replacement for the Riga class, the last of the cold war. These Frigates and guard ships appeared from the mid-1970 and 40 were built in several batches and evolutions. Sub-branches, like the Nerey class were designed for coastal patrol and used by the KGB Border guards. Until 1977, they were considered as traditional anti-submarine warfare vessels but this changd as armament was diversified. For NATO they were known as the Krivak, divided into four sub classes classes.

Development

Designed as Kresta class cruisers in reduction

The Krivak class frigates were designed as successors to the 1950s Riga class and thus, the very early designs emerged in the late 1950s already, matured as larger missile-armed anti-submarine ships in the sixties. In the end, some 42 ships were planned to be built before the collapse of the Soviet Union.
Project 1135 was developed in 1964-1966 at the Northern Design Bureau. The naval staff wanted a large anti-submarine ship, second class and ocean-going, based on projects 1134-A and 1134-B (Kresta class cruisers), but with a significantly reduced displacement. This program was supposed to take on a wide range of tasks, mosty around ASW defence air defense of ship formations, or escorting convoys through combat areas.

The reduction in displacement led to the deletion of an helicopter while the hydroacoustic of the 1134-B project was retaken. However the radar suite was too light to guide the main antiship missiles at full range, so ships were supposed to operate in search-and-strike pairs.
Initially, the main armament was to be the “Metel” missile-torpedo system, but during modernizations it was replaced by the more capable Rastrub-B, and doubled against surface targets.

Construction

Project 1135M Pytlivyy in 2009
Construction was carried out at three shipyards: A. A. Zhdanov in Leningrad, “Yantar” at Kaliningrad and “Zaliv” in Kerch. The serie was so long it was declined into three main variants:
Project 1135 21 ships built 1968-1981, NATO Krivak I
Project 1135M 11 ships 1973-1981, NATO Krivak II
Project 1135.1 7 ships 1973-1981 (NATO Krivak III) 7 built 1981-1990 differing in displacement and armament for the Border Guards.
Project 1135.2 Modified versions of the same, four Krivak I ships modified as Krivak IV.
Project 1135.5 Nerei 10 ships 1973-1981 (NATO Krivak III) for the Navy.

A total of 32 ships were built, 48 in absolute total including 40 for the Soviet Navy alone. 21 Krivak I until 1981 and another one was planned, but was not laid down. From 1975, in parallel were developed a modernization, Project 1135M were built with 11 built and the class was rounded by the border patrol ship “Nerei”, including three not given to the border guards, one was assigned to the Navy and two others to Ukraine.
In 1999-2013, under Project 1135.6, six ships were built as Talwar-class frigates, delivered for the Indian Navy.
From 2010, a program was setup to build six Project 1135.6R frigates for the Russian Navy. Main differences between with the export variant are the new weapons and updated hull using stealth technology.
Eventually after Bditelnyy commissioned in 1970, 40 ships were commissioned, including those of the Navt (Krivak I, II, IV) and eight Krivak III for the KGB Maritime Border Guard.
Their unique feature which distinguished themselves from all past designs was their their large bow missile box, stack and angled mast. US sailors seeing their well known silhouette since they used to be shadowed by them in the late 70s and 1980s used to sing “Hot dog pack, Smokestack, Knife in the Back, two Guns in the Back — Krivak.”

Post Cold War constructions:

The Indian Navy ordered six upgraded Krivak III ships, they became known as the Talwar class delivered in two batches, in 2003–2004 and 2011–2012. On 12 October 2010, also Yantar Shipyard, Kaliningrad announced being contracted for construction three new warships of the same type as India frigates and built in parrallel as those for the Indian Navy.

Design of the class

Hull and general design

All these ships, whatever the version, shared the same hull, and powerplant. In Standard they displaced 3,300 tons, and fully loaded, 3,575 tons. Compared to a Kresta II hull it was of course way shorter, more compact, but still relatively wide, with an overll lenght of 405.3 ft (123.5 m), a beam of 46.3 ft (14.1 m) and a draught of 15.1 ft (4.6 m). The hull was beamy all the way to the rounded transom stern. The prow was edgy and ended underwater with the sonar bulge. There were counterkeels and stepped sides, as well as a lower stern deck (or 4/5 long forecastle) ensuring some livability. However these ships had the reputation of being cramped. The Krivak I had 200 men for crew. This went down with more recent derivatives. This was indeed improved on recent Russian sub-projects, thanks largely to automation.
By dimensions and tonnage they had nothing to do with the small previous ASW frigates and more, for example, with semi-contemporary like the East German Parchim or simply the USN OH Perry, which were larger and bulkier.
The profile is balanced, with a low armament, guns at the rear, central bridge and structure supporting the lattice mainmast, small aft mast and blocky funnel. These ships had a low profile and they armed “to the brim”, notably when looking at their massive quad missile launcher formward, reminiscent of the old Kynda class missile cruisers.

Powerplant

These Frigates were not the first with Gas Turbines (The Petya class inaugurated this), but they had a much more powerful system: On two shafts they combined two M-8k, 40,000 shp (30,000 kW) or DK59 13.5 MW or DT59 16.9 MW gas-turbines and two M-62 7.4 MW or DS71 13.4 gas-turbines (for cruising) rated for 14,950 shp (11,150 kW total.)
Top speed was 32 knots (59 km/h) and range 4,995 nmi (9,251 km) at 14 knots (26 km/h).

Armament

ASW Missiles

Quad URK-5 (SS-N-14 ‘Silex’) SSM/ASW missiles: The Metel Anti-Ship Complex (“Snowstorm”) were anti-submarine missiles designed in the 1960s for the Kresta class cruisers, entering sevrice in 1969 and here in the Frigate variant, with later Krivak class given the the shaped charge (‘Rastrub’) usable now against shipping as well as submarines.
Like the ASROC, the missile carries an underslung anti-submarine torpedo drops above the suspected position, launched homing search. The 85RU/URPK-5 carries the UGMT-1 torpedo, multi-purpose for subs and surface ships. In later versions of the Krivaks, it was supposed to be replaced by the RPK-2 Viyuga (SS-N-15 ‘Starfish’) but the upgrade program was cancelled in 1991.

Variants

Project 1135 Burevestnik (Krivak I) 1975:

Design process started in 1956, role changed to ASW ships powered by gas turbines, with four SS-N-14 missile. Built at Zhdanov Yard (now Northern Shipyard), Leningrad, Yantar, Kaliningrad, Kamysh Burun Yard, in Kerch, Crimea with 21 ships built until 1981.

Bditelny before and after modernization 1971-1990

Project 1135M Burevestnik M (Krivak II) 1980:

They were fitted with single 100 mm AK-100 guns instead of two twin 76 mm AK-726, and fitted with a Variable Depth Sonar (VDS). All eleven built in Kaliningrad.

Project 11351 Nerey (Krivak III) 1990:

These ships lacked the SS-N-14 missile system replaced by a helicopter and its hangar, one 100 mm gun at the bow. All were built in Kerch for Soviet Border Guards (KGB). Two are now kept with the Russian FSB Coast Guard, and since 1990, one joined the Ukrainian Navy until scuttled in 2022 to avoid capture. An incomplete Krivak III, Ukrainian Hetman Bayda Vyshnevetsky by 1995 was retransferred to Russia and resold to the Korean People’s Navy. 8 ships were built.

Project 11352/11353 (Krivak IV) 2000:

Project 11353

Project 11352
This was a modernization of the the Krivak I: These were the Leningradski Komsomolets (renamed Legkiy in 1992), Letuchiy, Pylkiy and Zharkiy of the Krivak I group.
-RBU-6000 by SS-N-25 anti-ship missiles
-New radar, sonar, EW equipment.
Refits completed in 1990–1992, programme not extended to others, but cancelled with the collapse of the Soviet Union.

Project 11356 (Talwar class):

Advanced derivative built for the Indian Navy from 1999 to 2012. Three improved “Nerey” frigates were also ordered by the Indian Navy on 17 November 1997, also assimilated to the Talwar-class frigates. Three more were fitted in India with the new BrahMos missile. They were ordered by July 2006.

Project 11356R/M (Admiral Grigorovich class) 2011:

Derivative of the Talwar class intended for the Russian Navy. Six ordered for the Russian Black Sea Fleet under two contracts, signed in 2010–2011. First laid down on 18 December 2010. As the Ukrainian built gas-turbines were not delivered after the start of the war in Donbass by 2014, construction of Admiral Butakov and Admiral Istomin was suspended in the spring 2015. By October 2018, it was announced that Butakov and Istomin were to sold to India for $950 million, and completed there. The last frigate Admiral Kornilov is still to find a customer. sold abroad. Only three ships were built for the Russian Navy so far.

Career of the Krivak class ships

With 40 ships operational, there’s a lot to cover so i will go essential facts as reported from Russian sources. Full records, translated on ww2.dk
In 1975, a riot took place at the Storozhevoy, calling for a new communist revolution. This mutiny/defection inspired Tom Clancy for his “hunt for the red october” novel.
In 1988, one of these frigates, Bezzavetny, “bumped” aggressively the Ticonderoga class cruiser USS Yorktown, ousted from alleged territorial waters in the black sea. White house protests were about the differences between the Soviet limit and internationally recoignised limits.
As of 2012, several ships Pr.1135 and 1135M remained in the Russian Navy. A further evolution of the Project 1135 patrol ships, the Talvar-class were ordered to the Baltic Shipyard OJSC and PSZ Yantar OJSC. In 2013, the program to build three ships Project 1135.7 (improved Talwar) for the Black Sea Fleet commenced, as long as two additional for the Baltic Fleet but Project 11357 was later unified with the Project 22350 frigates in equipment and senors, to reduce differences to a minimum and simplify maintenance. Ten Admiral Gorshkov class are planned, most being built from 2006, but only three completed as now, the remainder planned until 2029.

“Watchful” was laid down at Yantar, Kaliningrad on 21 July 1968, launched 28 March 1970 and completed in 31 December 1970, she served with the Baltic, Decommissioned in 1996.
She was accepted into the Baltic Fleet 20.2.71 (with the 128th Brigade) and from June 1971 to October she was in qualifications and weapons tests, mainly in the Black Sea, fring the URPK-4 (SS-N-14) and Osa-M (SA-N-4). By 4 August 1971 she was visited by General Secretary L.Brezhnev and Navy Commander Gorshkov in Feodosiya. She stopped at Gdynia in Poland from 5.10 to 9.10.71 on her return trip. From 14 june to 29 november 1972 she operated in the Mediterranean with Task Force KUG-1 together with the cruiser “Oktyabrskaya Revolutsiya” and the frigates “Speshnyy”, “Slavnyy” “Bodryy” in ASW training, and supporting Egypt and Syria during their war with Israel. She visited Dubrovnik on her way back, in Yugoslavia and from 5-9 October 1973 visited Gdynia in Poland with “Silnyy” and escorting the cruiser Sverdlov, flagship of the Baltic Fleet. On 28 March to 18 april 1974 she operated in the North Sea and stopped again on 20-24 july in Gdynia. In October 1974 she was again in operations, the North Sea.

On 14-24 March 1977 she took part in the major Sever-77 Atlantic fleet exercise. From August 1977 to February 1978 she made a Mediterranean TOD, also pushing to the Atlantic and Carribean, visiting Cuba twice and tracking along the way NATO submarines and warship. Later she took part in “Baltika-78” exercise. In September 1978 she visited Copenhagen and by 2-6 October was back tracking NATO Baltic exercises. In January 1979 she visited Rostock in East Germany and on 3-10 October, Warnemünde. She made another major deployment between the Atlantic and Mediterranean, from 18 March to 27 June 1980 and too, part in Atlantika-80 exercise (27-30 June 1980 with the frigates Druzhnyy directly under Commander Gorshkov.

She visited Annaba in Algeria in June, and on her way back, Stettin in Poland in July, escorting in September-October the Hybrid Carrier Kiev with Slavnyy from the Baltic Straits to the Norwegian Sea. She crossed the Atlantic and by April-May 1981 she visited Havana and Cienfuegos with “Nikolayev”, “Svirepyy” and followed by the tanker Olekma for the “Khiron-20” exercise with the Cuban Navy. In May-July she was back in the Mediterranean, escorting the SSN K-503 through the Gibraltar strait for a visit to Annaba. In July-August 1983 she escorted Kiev from the Mediterranean to the Baltic.

From February 1984 to January 1986 she had a major overhaul and modernization at Yantar, Kaliningrad. She received the new URK-5 (SS-N-14B) missiles notably, had a new networks, overhauled electronics, machinery, etc. On 24 April 1986 she separted for a major exercizes of the of combined Warsaw Pact fleet under Commander N.I. Khovrin and in June 1987 took part in OBESK-87. From July 1987 to April 1988 she visited Stettin and by August-September 1988 she took part in Baltic tactical exercise, in December she escorted the cruiser Kalinin for her transit to the Northern Fleet. In May-June 1989 she took part to the OBESK-89 exercise and in October visited Rostock. In January-July 1990 she made a ong cruise to the Central and southern Atlantic and later was based at Luanda, Angola for a time, then when back she stopped at Antwerp in Belgium for the first time, in June 1991, as well as Amsterdam. In November-December she returned in the Mediterranean, scorting the Admiral Kuznetsov from Gibraltar to 64 degrees North. In June 1993 she took part in joint NATO exercise “Baltops-93” but soon after her crew was reduced, she as placed in reserve, and she was decommissioned on 31 July 1996, disarmed in December, sold for BU in late 1997, to a Virgin Islands company.

Built in Yantar, Kaliningrad she was accepted into the Baltic Fleet on 7 December 1974 with the 128th Brigade. In October she visited Rostock and for five months in January-May 1975 she operated in the Central Atlantic and Caribbean with Svirepyy. The famous mutiny took place on 8 November 1975 led by the deputy political commander, with the intent of sailing to Sweden (officially). The mutiny was ended by air attacks. Back to port, the entire crew was disbanded, replaced by the crew of Druzhnyy. In Januar-March 1976 she operated from Baltiysk and sailed around Africa as well as to Petropavlovsk-Kamchatka.

She was transferred to the Pacific Fleet on 6 november 1976 to the 173rd Brigade. In 1977 she operated off the Kuriles and Sea of Okhotsk, together with Razumnyy?
