The patrol ships of project 11661 are designed to perform complex tasks in the search and elimination of underwater, surface and air targets, in carrying out combat service, in escorting, as well as in protecting maritime economic zones. They are equipped with artillery, anti-ship, anti-aircraft and anti-submarine weapons.
A little from the history of the creation of ships of the project 11661
Patrol ships (corvettes) and rocket ships began to be developed in the early eighties. The development was carried out by the Zelenodolsk Design Bureau. The development of anti-submarine ships for coastal zones was carried out as the development of another project 1124M - a small anti-submarine ship, with "Livn" - an anti-submarine missile cruiser... Then they developed two versions of tactical and technical assignments, and a year later they proposed both versions of draft designs - an anti-submarine ship with a PLRK in accordance with project 1124M and an anti-submarine ship with a displacement of up to two thousand tons with more significant efficiency.
In the same year, following changes in claims by Navy to the project, the second project was assigned the number 11660 (and the export version - 11660E) and reclassified into a patrol ship. The analysis of research in the projects showed that it was possible to hand over the "watchdog" in the export version as early as 1990, while the Soviet version could have been handed over no earlier than two years later.
Back in the mid-eighties, a requirement was put forward to equip patrol ships (TFR) with Uranus anti-ship missile complexes, which were planned to be developed in 1987. According to the December Decree of the Council of Ministers of the USSR in 1984, it was decided to develop patrol ships according to project 11661. Draft projects 11661 with CODOG propulsion systems were completed a year later.
By the beginning of 1986, the technical design of patrol ships under project 11661 was completed. Later, it was decided to unify the ships of projects 11660 and 11661 by eighty-five percent, start work and rearrange them in a single structural platform with various weapons, differences in engines and equipment.
In September 1986, they began to defend project 11661. Following the modifications for Uranus and Zarya and other equipment, they formulated the concept of the Basic Platform for Ship Families in the final version. To test the shape of the hulls and the effect of the radomes of the antennas to determine the seaworthiness, a ship model was created and tested. The technical project of the 11661 project was approved a year later.
Then they set the task to unify projects 11660 and 11661. Using the concept of the "Basic platform" Zelenodolsk Design Bureau began to produce working design documentation for project 11661, as well as develop technical projects for project 11660.
After all the agreements and approvals, the ships were laid. And already in 1993, the lead ship of Project 11661 was destined to go down to the water with the beginning of its completion. At the beginning of 1995, a crew appeared in Zelenodolsk to master the patrol ship. In the same year, several ships were refused from a foreign customer (according to some Indian sources), and all work on their construction was stopped.
In addition, in the same year, the construction of the ship was stopped with ninety-three percent readiness. The crew was disbanded, the ship was mothballed due to underfunding, as well as due to the fact that the customer himself (the Russian Navy) was not fully determined on different types patrol ships.
However, in the period 1995-1998 Zelenodolsk Design Bureau developed export projects "Gepard" and "Gepard-3.9" for a foreign customer.
In 2001, the leadership of the Navy decided to complete the construction of one of the ships under the project 11661K, which was supposed to enter the Caspian flotilla with the name "Tatarstan". The ship lost its anti-submarine weapons. On it, the project was adjusted to meet all the requirements. In April 2002, a crew appeared in Zelenodolsk to take possession of the new ship.
At the same time, they carried out inclining with the ship and found out that the displacement deviated from the calculations by up to one ton. In July 2002, "Tatarstan" managed to successfully leave Zelenodolsk Shipyard in order to go to the Makhachkala region to carry out test activities. The sea test passed with a five-point excitement. As a result, the ship was adopted by the Russian Navy, and the Caspian Flotilla acquired its own flagship in August 2003.
The predecessors of the "Cheetahs"
The predecessors of the Cheetahs were the Albatrosses, which turned out to be small anti-submarine ships under the project 1124 with the NATO code designation - "Grisha class corvette". They were built in 1970-1980 for the Soviet Naval Forces, which include two main series of projects 1124 and 1124M.
Samples of project 11661 - "Tatarstan" and "Dagestan"
The firstborn in Project 11661K was the ship already known as Tatarstan, which entered service in August 2003. He was subsequently sent to the Caspian Flotilla as its flagship.
The second patrol ship happened to be "Dagestan". Its delivery to the Navy was originally planned for the first half of 2012. However, it was postponed due to the seriousness of the damage received back in January of the same year during the Black Sea mooring tests near the city of Novorossiysk. After restoration and repair measures, "Dagestan" managed to reach the Caspian Sea to participate in the second stage in the state tests for the implementation of missile firing at coastal targets "Kalibrom-NK".
Participation in the shooting at a distance of one hundred nautical miles was carried out safely. The patrol ship "Dagestan" also had to take part in the parade on the Day of the Russian Navy in the city of Astrakhan. In the autumn of the same year, he was involved in the Kavkaz-2012 maneuvers, in their naval unit.
However, three years later the whole world learned about "Dagestan". So, in October 2019, at night, a naval strike group in the Caspian Sea carried out a massive strike using cruise missiles. The strike was inflicted by the "Caliber NK" complex sea-based on the infrastructure of ISIS in Syria. The Dagestan was also composed of six ships.
Housings
Ship hulls are ten watertight compartments. The material for their execution was low-alloy steel, and for the superstructure blocks - aluminum-magnesium alloy, resistant to marine environments. In the event of flooding of two adjacent compartments, the ship will remain afloat, having a course with the preservation of combat effectiveness.
Power plant and running properties
The main power plant is the twin-shaft CODOG. With a medium-speed diesel engine 61D with a power of 8000 horsepower, using a complex gearbox, it is provided with all cruising modes, and with the help of two gas turbines with a total power of 29000 horsepower, the ship's full speed up to 28 knots is provided. The electrical installation consists of three diesel generators, 600 kW each.
The crew of the patrol ship is 121 military personnel, of which 15 are officers.
Armament of the ships "Tatarstan" and "Dagestan"
The ships under the project 11661 have powerful missile, anti-aircraft missile and artillery weapons. The main weapon of "Tatarstan" is "Uranus". This is a strike complex with Kh-35 anti-ship cruise missiles, with a firing range of up to one hundred and thirty kilometers.
The "Dagestan" is armed with a universal missile system- "Caliber-NK", which can use high-precision cruise missiles of several types. They hit surface and coastal targets with a range of up to three hundred kilometers. From artillery weapons - 76.2-mm artillery complex AK-176M and 30-mm automated twin artillery mount AK-630M, which ensure the defeat of sea, ground and low-flying air targets.
Frigates "Gepard-3.9" - ships of a new generation
Frigates of the "Gepard-3.9" class are ships of a new generation. They were developed by Zelenodolsk Design Bureau with an existing universal base platform. The prototype for "Gepardov -3.9" was a missile ship named "Tatarstan" from project 11611, and "Dagestan" is the second such built domestic missile ship, a version corrected at the insistence of the customer in the project 11611K.
The construction of frigates for the Vietnamese customer is still carried out according to established requirements The Naval Forces of this state. With a total displacement of up to 2,100 tons, they have a length of 102 meters, a width of just over 13 meters, and a draft of just over 5 meters. The ships have a combined diesel-gas turbine power plant (in accordance with the CODOG scheme).
With this power plant, ships develop a speed at full speed of up to 28 knots, and an economic ten-knot speed allows frigates to sail at ranges of up to 5,000 nautical miles. Autonomous sailing is twenty days. Well placed residential and office space, the presence of a system that conditions the air and maintains the necessary conditions microclimate will contribute to good conditions habitability, which is simply vital in tropical climates.
"Cheetah-3.9" are multipurpose ships designed for patrolling in territorial waters and exclusive economic zones, striking enemy surface targets, providing fire support for airborne units, to provide anti-aircraft and anti-submarine defense in convoy activities.
As a result, their weapons are diverse and well balanced. These include the Urany-E anti-ship missile systems, the AK-176M universal 76.2-mm artillery mounts, and the small-caliber anti-aircraft system. Control over the control of all these weapons is carried out by the responsible high standards of our time, the combat information and control system "Sigma-E". The stern of the ship has a helipad for takeoff and landing. In addition, the helicopter has a special shelter - a hangar, which will protect it from sea winds and waves.
Soon "Cheetahs" will make the transition to the Baltic Sea, where they will be tested. Implementation of the contractual part for the construction of patrol ships for a Vietnamese customer can change the correlation of the ships produced by the enterprise. So, about forty percent will go to the military and sixty percent to civilian products(before, 30% went to military products and 70% to civilian products).
In the presence of the base platform "Cheetah", you can not be limited to the construction of only multipurpose ships, but you can also build ships with reinforced shock, anti-submarine and anti-aircraft missiles, with a wide variety of power plants and electronic equipment. With the help of the same platform, ZPKB developed a modification of ships for patrolling on the high seas, which have a greater autonomy of navigation. It should be especially noted that the family of "Cheetah" is relatively inexpensive in relation to similar ships of foreign buildings.

Patrol ships of the project 11661 (code "Gepard", according to NATO codification - Gepard)- a type of patrol ships of the Russian and Vietnamese fleets. Ships of the series are being built at the Zelenodolsk plant named after A.M. Gorky since 1990.
In the early 1980s, it became necessary to develop a new coastal patrol ship. It was supposed to replace the ships of Project 1124. This was due to the change in the purpose of the patrol ships of Project 11540, which in the final version were supposed to replace the larger patrol ships of Project 1135. The Zelenodolsk Design Bureau headed by chief designer Yu.A. Nikolsky, and then V.N. Kashkin.
Due to the requirements of the Navy for the placement of a powerful sonar station, the ship's displacement increased to 2000 tons, which became close to the ships of the competing project 12441. Those were more powerful anti-ship missiles and the presence of a helipad.
At the end of 1990, the lead ship of Project 11660 was laid down, which was named Burevestnik, but after a while its construction was stopped. In 1995, its construction was discontinued and the ship was mothballed. The ship was later dismantled.
The second ship was laid down in 1993 under the export project 11661 for the Indian Navy, but in 1995, when it was almost ready, funding stopped. Later, it was completed according to the project 11661K, adjusted for the Russian Navy, and launched under the name "Tatarstan"; it entered service on August 31, 2003 and became the flagship of the Caspian Flotilla.
The third TFR was also founded according to the 11661K project in 1991 and was named "Dagestan". Its delivery to the fleet was originally planned for the first half of 2012, but was postponed due to damage received in January 2012 during mooring trials on the Black Sea near Novorossiysk.
In July 2012, after restoration and repair work, "Dagestan" entered the Caspian Sea as part of the second stage of state tests for the implementation of missile firing at a coastal target from the "Caliber-NK" missile system. Shooting at a distance of 100 nautical miles was successful and on November 28, 2012, "Dagestan" became part of the Russian Navy.
They have a traditional flush-deck architecture with 10 watertight compartments. The ship's superstructure is made of aluminum-magnesium alloys to ensure low visibility(the so-called stealth technology).
The patrol ships of the project 11661 "Gepard" have powerful missile, anti-aircraft missile and artillery weapons. The main weapon of Project 11661E ships and the RK Tatarstan is the Uran (Uran-E) anti-ship missile system with Kh-35 (E) cruise missiles, which has a firing range of up to 130 km (up to 260 km for Uran-U) with Kh-35U missiles).
Project 11661K ship, Dagestan, is the first Russian Navy ship armed with the Kalibr-NK universal missile system, which can use several types of high-precision cruise missiles capable of striking surface, underwater and coastal targets at a distance of up to 300 km.
Artillery armament includes a 76.2 mm bow artillery mount AK-176M (ammunition - 152 rounds) and two 30 mm automated ones with ammunition of 2000 + 1000 rounds each, which ensures the fight against sea, ground and air targets. The rocket ship "Dagestan" also has two 14.5 mm naval pedestal machine gun mounts.
For air defense on the ships of projects 11660 and 11661, as well as on the Tatarstan missile complex, the Osa-MA-2 anti-aircraft missile system with an ammunition of 20 missiles is used. On the Dagestan ship, instead of the Osa-MA-2 air defense system and two AK-630s, it is installed, and on the ships of the 11661E project, its export modification, the Palma, is installed on the forecastle, with both AK-630s being installed in the stern of the superstructure side by side.
As anti-submarine weapons on the ships of pr. 11660 and 11661, two twin-tube 533 mm torpedo tubes were provided. On the ships of the 11661E project, one is used as anti-submarine and anti-torpedo weapons. It is possible to equip ships with other weapon options, including the Ka-27 ship-based anti-submarine helicopter.
V different time the ships were equipped with various radar and electronic equipment. So, the ships were installed radar complex 34K1 "Monolith", radar station general detection MR-352 "Positive", navigation radar MR-212 "Vaygach", artillery fire control system MR-123 "Vympel" and GAS "Zarnitsa". The anti-sabotage OGAS MG-757 Anapa-M is installed on the Tatarstan ship.
To control the firing of RBU on ships of pr. 11660 and 11661, PUSB "Tempest" was used, on ships of pr. 11661E, PUSB "Purga-ME" was used. Electronic warfare complex consisted of two KL-101 launchers of the REP PK-16 system or of four KT-216 launchers of the PK-10 "Brave" complex.
On the RK "Dagestan", the "Monolit" radar was replaced by "Mineral-M", and the general detection radar was replaced by "Positive-M1". Also installed hydroacoustic complex (GAK) type MGK-335, electronic warfare system TK-25 and BIUS "Sigma". Ships of the project 11661E are equipped with equipment similar to those installed on the "Dagestan" in the export version with some differences in its composition.
The main power plant is two-shaft, type CODOG. Medium-speed diesel type 61D with a capacity of 8000 hp through a complex gearbox provides all cruising modes, and two gas turbines with a total capacity of 29,000 liters. with. (one for each shaft) provide the full speed of the ship up to 28 knots. The power plant includes three diesel generators of 600 kW each.
Patrol ship / corvette / rocket ship. Development started in 1982 by Zelenodolsk Design Bureau (Zelenodolsk), chief designer - MM Nesterenko, since 1986 - VN Kashkin. The development of the anti-submarine ship of the coastal zone was carried out as a development the IPC project Project 1124M with PLRK "" since February 1982 Two variants of the tactical and technical assignment were developed and in 1983 two variants of the draft design were proposed - an anti-submarine ship with PLRK "" significantly higher efficiency. In April 1983, after changing the requirements of the Navy for the project, the second project received the number 11660 (export version - 11660E) and was reclassified in the TFR. An analysis of the development of the projects showed that the delivery of the export version of the TFR could be planned for 1990, while the readiness for the delivery of the version for the Soviet Navy in terms of weapons systems could not be earlier than 1992.

In 1984, 1 Central Research Institute of the USSR Ministry of Defense put forward a requirement to equip the TFR with the Uranium anti-ship missile complex, the development of which was planned to begin in 1987. In December 1984, the USSR Council of Ministers adopted a Decree on the development of an export TFR pr.11661, TFR for the USSR Navy, pr. 11660 and PSKR pr.11662. The chief designer was appointed M.M. Nesterenko, the deputies were G.A. Zolotarev and V.V. Ivanov. Draft pr.11661 with a CODOG-type propulsion system (diesel + two gas turbine engines) was completed in early 1985. At the end of 1985, the preliminary design of the SKR pr.11660 was completed. At the beginning of 1986, the technical design of the SKR pr.11661 was completed, and during the year an addition to the draft pr.11660 was developed for the PSKR pr.11662. The USSR SMEs set the task of unifying the ships of Project 11660 and Project 1161 by 85% and began work on re-assembling projects under a single constructive platform with different weapons systems, differences in propulsion systems and equipment. In 1986, the chief designer of the project, M.M. Nesterenko, for health reasons, asked to be relieved of his post and V.N.Kashkin was appointed instead.
At the beginning of September 1986, the defense of projects 11660, 11661 and 11662 began. After modifications for the Uran missile complex, the Zarya spacecraft and other equipment, the concept of the "Basic platform for a family of ships" was finally formulated. To test the hull shape and the effect of the GAS antenna fairing on seaworthiness, a model of the SM-22 ship was created and tested (tests were carried out by V.G. Pasechnik and V.N. Aleshin). The technical project of pr.11661 and the preliminary design of pr.11660 were approved at the beginning of 1987. The task was set when developing the technical project of pr.11660 to ensure unification with pr.11661 by 80%. Using the concept of "Basic Platform" Zelenodolsk Design Bureau began to produce a working design documentation on pr.11661 and development of technical projects pr.11660 and pr.11662. At the same time, there was a release of working design documentation for Project 11540.
Model SM-22 on testing (Zelenodolsk Design Bureau. Checked by sea. 60 years 1949-2009, Kazan, Helicopter, 2009).
The creation of a reserve for the head ICR pr.11661 at Zelenodolsk Shipyard began at the end of 1987. In 1988, the technical project of pr.11661 was approved, the development of working design documentation was started, and pr.11662 is being adjusted taking into account the wishes of the USSR Border Troops. The head ICR project 1161 (factory # 951) was laid down at Zelenodolsk Shipyard in May 1990 (October 20, 1988, Project 11660 - according to other data). The following were laid down works # 952 and 953, Project 1161, and the lead ship, Project 11660 (factory # 901). The development of working design documentation for Project 11662 has begun.
In 1991, an initiative study was presented, and later an abbreviated technical project of the multipurpose SKR pr.11663 - a variant of the SKR pr.11660 with a helicopter, URO, air defense, PLO and with BIUS. When choosing the TFR for the construction of the Navy, he preferred pr.12441 TsMKB "Almaz" (which was never built), and the development of the TFR projects pr.11660 and pr.11663 were closed in 1992 by the Resolution of the Council of Ministers of Russia. Work on Project 11662 has been continued so far.
In July 1993, the lead ship, project 1161, factory # 951, was launched and its completion began. In February 1995, a crew arrived in Zelenodolsk to master the TFR. During 1995, a foreign customer (presumably, India) abandoned the ships No. 952 and 953 and their construction was stopped. At the end of 1995, the construction of the ship No. 951 was discontinued with 93% readiness, the crew was disbanded, the ship was mothballed due to lack of funding and due to the uncertainty of the customer (Russian Navy) between different types TFR.
Finishing construction afloat SKR pr.11661 serial number 951, Zelenodolsk Shipyard, presumably 1995 (Zelenodolsk Design Bureau. Checked by sea. 60 years 1949-2009 Kazan, Helicopter, 2009).
Between 1995 and 1998 Zelenodolsk Design Bureau developed a family of export projects "Gepard", completed a technical project "Gepard-3.9" for a foreign customer. In 1998, Project 11662 was closed and work on the laid down ship of the project was stopped when the ship was 11% ready.
In 2001, the leadership of the Navy made a decision to complete the construction of the ship No.951 for Project 11661K (the first with this project number) for the Caspian Flotilla under the name "Tatarstan". The submarine armament was removed from the ship, the project was corrected. In early April 2002, a crew arrived in Zelenodolsk to master the ship. In July 2002 the ship was inclined - the deviation from the calculated displacement was 1 ton. On July 12, 2002 "Tatarstan" left the water area of the Zelenodolsk Shipyard and went to Makhachkala for testing. In May 2003, the SKR passed seaworthy tests at sea waves of 5 points. The ship was accepted by the Russian Navy as the flagship of the Caspian Flotilla on August 31, 2003.
According to unconfirmed reports, the last ship of the project for the Russian Navy was the Dagestan TFR. The construction of other ships of the project 1161K for the Russian Navy is apparently not planned. The conclusion was made, incl. based on the fact that the production of an artillery installation for the Russian Navy has been discontinued. Although, this may mean equipping new ships of modernized projects with a 100 mm installation or.
Design- the case consists of 10 waterproof compartments, the case material is low-alloy steel. The superstructure is made of corrosion-resistant aluminum-magnesium alloy. The ship retains its buoyancy and combat capabilities when any two adjacent compartments are flooded. The ship is equipped with an air conditioning system. There are active stabilizers.
During the construction of corvettes pr.11661E for the Vietnamese Navy, the Cherepovets Matellurgical Plant supplied two types of steel ():
- structural sheet of grade 10ХСНД;
- high-strength ship steel D40S.

Project 11661E "Cheetah-3.9"- TFR / coastal corvette. Two ships were built for the Vietnamese Navy. The contract was signed in 2006. The head ship # 954 was laid down on July 10, 2007, launched on December 12, 2009, sent to the customer by the carrier from Baltiysk, probably on December 10, 2010. The lead ship successfully passed mooring and sea trials, performed test firing of the Uran anti-ship missile system in the Baltic. On March 5, 2011 the flag of the Vietnamese Navy was raised on the ship and the ship was named "Dinh Tien Hoang". It is unlikely, but it is possible that during the construction of the ships the backlog of the ships of Project 11660 and Project 11662 was used, the construction of which was discontinued in 1992-1998.
Project 11661TO- TFR / corvette for the Caspian Sea / missile ship, modification of Project 1161 / 11661K (first) with modified armament. The lead ship, No. 952, was laid down in 1990 as the ship of Project 1161, was completed according to the modified Project 1161K as "Dagestan" since 2002. It should have been launched according to plan in 2010, later - in March 2011, actually launched on April 4, 2011. Commissioning is planned for 2011 (plans for 2010). The second serial ship, probably No. 953 Burevestnik, is in the shops of Zelenodolsk Shipyard. On September 13, 2011, the Dagestan TFR left Zelenodolsk for Novorossiysk to undergo tests, which should begin on October 1, 2011. In 2012, the ship is planned to be accepted into the Navy. 2002 August 09 - during the visit of the Minister of Defense of Russia S.B. Ivanov to the Zelenodolsk Shipyard, a decision was made to build the second ship, project 1161K. Probably, work on completion of project 1161K of the Dagestan missile ship began in 2005 or earlier. 2003 September - the rocket ship "Tatarstan" successfully carried out an operation to rescue the ship "Russia" in a storm in the Caspian Sea.

Project 11661 (code "Gepard", according to NATO codification - Gepard) is a type of patrol ships of the Russian and Vietnamese fleets. Ships of the series have been built at the Zelenodolsk plant named after A.M. Gorky since 1990.
In the early 1980s, it became necessary to develop a new coastal patrol ship. It was supposed to replace the ships of Project 1124. This was due to the change in the purpose of the patrol ships of Project 11540, which in the final version were supposed to replace the larger patrol ships of Project 1135. The Zelenodolsk Design Bureau headed by chief designer Yu. A. Nikolsky, and then V.N.Kashkin.
Due to the requirements of the Navy for the placement of a powerful sonar station, the ship's displacement increased to 2000 tons, which became close to the ships of the competing project 12441. Those were distinguished by more powerful anti-ship missiles and the presence of a helipad.
At the end of 1990, the lead ship of Project 11660 was laid down, which was named Burevestnik, but after a while its construction was stopped. In 1995, its construction was discontinued and the ship was mothballed. The ship was later dismantled.
The second ship was laid down in 1993 under the export project 11661 for the Indian Navy, but in 1995, when it was almost ready, funding stopped. Later, it was completed according to the project 11661K, adjusted for the Russian Navy, and launched under the name "Tatarstan"; it entered service on August 31, 2003 and became the flagship of the Caspian Flotilla.
The third TFR was also founded according to the 11661K project in 1991 and was named "Dagestan". Its delivery to the fleet was originally planned for the first half of 2012, but was postponed due to damage received in January 2012 during mooring trials on the Black Sea near Novorossiysk. In July 2012, after restoration and repair work, "Dagestan" entered the Caspian Sea as part of the second stage of state tests for the implementation of missile firing at a coastal target from the "Caliber-NK" missile system. Shooting at a distance of 100 nautical miles was successful and on November 28, 2012, "Dagestan" became part of the Russian Navy.
The patrol ships of the project 11661 "Cheetah" have a traditional flat-deck architecture with 10 watertight compartments. The ship's superstructure is made of aluminum-magnesium alloys to ensure low visibility (the so-called stealth technology).
The patrol ships of the project 11661 "Gepard" have powerful missile, anti-aircraft missile and artillery weapons. The main ships of Project 11661E and the RK Tatarstan are the Uran (Uran-E) anti-ship missile system with Kh-35 (E) cruise missiles, having a firing range of up to 130 km (up to 260 km for Uran-U with missiles Kh-35U). Project 11661K ship, Dagestan, is the first Russian Navy ship armed with the Kalibr-NK universal missile system, which can use several types of high-precision cruise missiles capable of striking surface, underwater and coastal targets at a distance of up to 300 km.
Artillery armament includes a 76.2 mm bow artillery mount AK-176M (ammunition - 152 rounds) and two 30 mm automated artillery mounts AK-630M with an ammunition load of 2000 + 1000 rounds each, which ensures the fight against sea, ground and air targets. The rocket ship "Dagestan" also has two 14.5 mm naval pedestal machine gun mounts.
For air defense on ships of projects 11660 and 11661, as well as on the RK "Tatarstan" the anti-aircraft missile system "Osa-MA-2" with ammunition of 20 missiles is used. On the ship "Dagestan" instead of the OSA-MA-2 air defense system and two AK-630s, the ZRAK "Broadsword" is installed), and on the ships of the project 11661E, its export modification - "Palma" is installed on the forecastle, while both AK-630s are installed in aft superstructure side by side.
As anti-submarine weapons on the ships of pr. 11660 and 11661, two twin-tube 533 mm torpedo tubes were provided. On the ships of Project 11661E, one RBU-6000 rocket launcher is used as anti-submarine and anti-torpedo weapons. It is possible to equip ships with other weapon options, including the Ka-27 ship-based anti-submarine helicopter.
At different times, the ships were equipped with various radar and radio-electronic means.
