Patrol ships of the project 11661 cheetah. Strike missile armament
Ships of the coastal or near sea zone in the Russian Navy today are represented by a whole cohort of modern combat vessels, which have powerful and powerful weapons. Watchmen today not only adequately represent the St. The patrol ships Project 11661 "Tatarstan" and "Dagestan" are today the basis of the combat power of the Caspian military flotilla, being the most powerful combat units in the Caspian.
This type of ships was created for a long time and was only realized in metal at the beginning of the new millennium. Accordingly, the new patrol boats have absorbed all the best that the domestic shipbuilding had at its disposal. SKR, according to the new classification - corvette, project 11661 on full grounds can be considered the most modern and combat-ready ships in the Russian Navy.
The concept of creating modern patrol ships
The class of patrol ships was most developed in the Soviet Union. Unlike their foreign counterparts, in the USSR, patrol boats turned into full-fledged combat ships capable of performing a huge amount of work. In terms of the number and variety of weapons, technical equipment and seaworthiness, Soviet patrol boats were almost equal to destroyers. Due to their versatility, patrol ships were considered the most massive ships of the Soviet Navy, carrying combat service in all maritime theaters.
Soviet shipbuilders managed to achieve a high technological level in the design and construction of ships of this class. Which, accordingly, affected their number and combat capabilities. However, the tendency towards the construction of large-sized watchdogs that emerged in the mid-70s and early 80s, the desire for gigantomania, were revised. Finally, it was decided to start designing patrol ships in their traditional form. These were supposed to be vessels of small displacement, possessing good seaworthiness and equipped with the most modern means weapons.
The first step in this direction was the 11611 project, on which work began back in 1985. The concept of building patrol boats specially designed to operate in the near sea zone in closed maritime theaters prevailed. The project 1124 small anti-submarine ships, which were massively built in the 70s, were chosen as the base point. In this context, the desire to re-create a universal ship, which will combine a variety of functions, can be traced. V terms of reference for the new project, the goals and objectives were spelled out that will be solved by the new ships. Patrol ships will have to perform the following functions:
- providing patrolling of the coastal water area, including the 200 mile economic zone;
- protection of coastal sea communications and coastal infrastructure facilities from opposition from the forces of the fleet and aviation of a potential enemy;
- search and fight against submarines of a potential enemy;
- ensuring the convoy of sea transport.
To perform the corresponding functions, the ship must have high seaworthiness, sufficient navigation autonomy and the necessary set of weapons. Navigation and radar equipment, concentrated on board the ship, must ensure the fulfillment of the assigned combat mission in full.
As a result, the shipbuilders were tasked with creating a powerful warship. In other words, on a small seaworthy platform, the entire existing complex of weapons should be installed, including artillery mounts, missile and anti-submarine weapons, and air defense equipment.
The story with the project 11611
One of the conditions, which was set by the naval sailors, was to build the ship at the shipyards located on the Volga. It was assumed that with the successful completion of the design work, the newly built ships could be transferred along the Volga to the Baltic or to the Black Sea region. In addition, the Zelenodolsk Design Bureau (Republic of Tatarstan) had production facilities and rich experience in designing small warships.
Design work began in 1982 on the basis of Project 1124M anti-submarine ships with a more stable power-to-weight ratio and increased seaworthiness. In the technical description for the project, the new ship was now called a near sea zone patrol ship. Initially, the project received the code 11660. It was envisaged to create and export version of the new patrol boat 11660E. In the future, the project has undergone changes. The patrol ship was to be equipped with the Uranus anti-ship missile system, the development of which was at the final stage by that time.
In this regard, it was necessary to begin work on a more powerful and more advanced ship in combat equipment. After a sketch of a new patrol ship was presented to the high naval leadership, in December 1984, by the Resolution of the Council of Ministers, design work on the creation of a new TFR was started. In 1986, the first ship was 80% completed and, after unification with Project 11660, was chosen as the base platform for a new family of ships.
Finally, the project, ready in all technical details, was approved in 1987, after which the development of production and design documentation began at the Zelenodolsk Design Bureau. At the same time, preparations for the laying of the lead ship of the project were carried out at the production facilities of the shipyard. All bureaucratic measures and delays took 2.5 years. Only in the late spring of 1990 was the official laying ceremony for the lead ship. The firstborn received the serial number 953. The technical documentation included the data - the patrol ship of the project 11661 under the code "Gepard".
It should be noted that initially the ship of the project 11660 was laid down, which was named "Burevestnik". In fact, I will fight the laying down of the second ship, only already within the framework of the export project 11611E, which India ordered for its Navy. The third patrol was laid down in 1991, using the created constructive and technical groundwork obtained during the design of the first two ships.
The construction of the TFR "Burevestnik" was planned to be completed in 1993. The fate of two other vessels of this project should have developed in a similar way, but the collapse Soviet Union made significant adjustments to subsequent construction plans. Due to a lack of funding, the construction of the ships was suspended. In heavy economic conditions building new ships for the young Russian navy was a burdensome task. In 1993, it was decided to complete work within the framework of project 11660, reorient all technical documentation and production in order to build a ship of project 11611.
The ships were half-and-half lowered into the water with grief. The construction of ships was either resumed or suspended. In 1995, the lead ship "Burevestnik" was dismantled. The remaining two ships began to be completed as part of the 11611K project already for the needs of the domestic fleet. The second ship, which had already been launched, received a new name in 1996, becoming the TFR "Tatarstan". In accordance with the NATO classification, the new Russian patrol ship of the project 11661K "Gepard" was classified as a corvette. As for the foreign contract, at the end of the 90s a new project of patrol ships "Gepard - 3.9" was specially developed. However, nothing significant in the further fate of the ships of Project 11611 happened. Ships in varying degrees of readiness continued to remain on the stocks of the Zelenodolsk shipyard. It was only in 2001 that the ship with the serial number 951 under the name "Tatarstan" was decided to be completed. The watchman was supposed to be part of the Caspian military flotilla.
The following year, the last dock work was completed, and the development of the ship by the crew began. In the summer of 2002, the new TFR "Tatarstan" was transferred to the Caspian Sea, where complex tests began. A year later, in August 2003, the patrol ship was enlisted in the Caspian Naval Flotilla, becoming the flagship of the naval formation.
The second ship, serial number 952, finally waited for the moment to be noticed. They also decided to finish building the ship to replenish the ship's composition of the Caspian Naval Flotilla. Accordingly to the place of service and the name that the ship received - "Dagestan".
In 2012, the new ship went to the Caspian Sea to undergo a complex of tests. Unlike its older brother TFR "Tatarstan", the new ship received shock weapons. Instead of the Uranium anti-ship missile system, the Kalibr-NK tactical anti-ship missile system was installed on it. In the fall of 2012, the ship was enlisted in the Caspian military flotilla. Due to the fact that the complex of weapons on the second ship has changed, its purpose has changed. It was no longer a patrol ship, it was the Dagestan missile ship. In order to unify the crew of the Caspian military flotilla, the flagship Tatarstan was also transferred to the category of rocket ships.
Design features of project 11661 missile ships
After the launching of the rocket ship "Dagestan", the further construction of other ships within the framework of the project 11661K was recognized as inexpedient. As for the built ships, their design has a number of curious and interesting features. In tactical terms, the characteristics of the ships are as follows:
- displacement standard 1500 tons;
- the length of the ship is 102 m with a width of 13.2 m;
- draft of the ship 3.6 m;
- the total capacity of the two gas turbine power plants is 29 thousand l / s;
- maximum speed of 28 knots;
- the maximum cruising range with an economical course of 14 knots is 3500 miles;
- the ship's crew consists of 93 sailors and officers;
- sailing autonomy is 15-20 days.
With such relatively modest parameters, the ships have high seaworthiness and powerful armament. On a platform with a displacement of 1,500 tons, the shipbuilders installed the Uran and Caliber-NK missile systems. These systems are the main armament of ships. Rocket ship of project 11661K "Gepard" "Tatarstan" remained with the original set of weapons. Its main weapon is the Uranium anti-ship missile system. The younger brother of "Tatarstan" is already equipped with the universal anti-ship missile "Caliber-NK", whose cruise missiles can hit any ground and surface targets.
The presence on board of perfect anti-submarine weapons and air defense systems makes these ships serious and formidable combat units. The air defense of the ships is provided by the AK-630M artillery system and the Osa-MA-2 air defense missile system. The newer ship is already equipped with a stationary artillery-missile system "Broadsword". In addition to them, there are portable air defense systems "Igla-M".
On the ships of the project 11661K there are no anti-submarine weapons. Both ships are equipped with modern navigation and radar equipment. For the first time on the ships of the Caspian military flotilla, the Ka-27 search and rescue helicopter, based on an open takeoff and landing site, was included in the technical equipment.
The design of the ship can be called successful. The main body is made of steel. The superstructure of the ship is made of a special aluminum-magnesium alloy, thanks to which the main part of the above-deck part of the ship is resistant to corrosion.
The set of ship hulls was built taking into account technical innovations. When two adjacent compartments are flooded, the new Russian ships can not only retain their buoyancy, but also remain combat-ready units of the fleet.
Corvettes of project 11661 today
In 2017, the place of the flagship of the Caspian military flotilla was taken by the newer and more advanced ship "Dagestan". In terms of its tactical and technical characteristics, this ship fully complies with the requirements for ships of this class. A reference to your past, in which ships were planned to be built by ordinary patrol boats, will not be appropriate today. The complex of weapons makes these ships full-fledged combat ships capable of withstanding any enemy at sea. In the Caspian Sea, the new Russian corvettes of Project 11661K "Gepard" have no equal, both in terms of displacement and firepower.
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 coastal zone anti-submarine ship was carried out as a development of the project MPK pr.1124M with PLRK "" "from February 1982. Two variants of the tactical and technical assignment were developed and in 1983 two variants of the preliminary design were proposed - an anti-submarine ship with PLRK" "in the dimensions of the MPK pr .1124M and anti-submarine ship with a displacement of up to 2000 tons with 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, the 1st 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 Resolution on the development of the export TFR pr. 1161, the TFR for the USSR Navy, pr. 11660 and PSKR pr.11662. The chief designer was appointed M.M. Nesterenko, deputies - G.A. Zolotarev and V.V. Ivanov. Draft pr.11661 with a CODOG-type propulsion system (diesel + two gas turbine engines) was completed at the beginning of 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 project 1161 and the preliminary design of project 11660 were approved at the beginning of 1987. The task was set when developing the technical project of project 11660 to ensure unification with project 1161 by 80%. Using the concept "Basic Platform" Zelenodolsk Design Bureau began to issue working design documentation for pr.11661 and the 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 the works # 952 and 953 of the project 1161 and the lead ship of the project 11660 (the factory # 901). The development of working design documentation for pr. 11662 has begun.
In 1991, an initiative study was presented, and later an abbreviated technical project multipurpose SKR pr.11663 - a variant of SKR pr.11660 with a helicopter, URO, air defense, PLO and 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 of 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 of 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 on 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.

"Cheetah-1"- a variant of the export TFR based on pr.11660 - instead of a towed GAS - a helipad, without a hangar for a helicopter, the Osa-M air defense missile system. Developed in the late 1990s. "Cheetah-2"- a variant of the export TFR based on the project 11660 - instead of a towed GAS - a helipad with a hangar for storing a helicopter, there is no Osa-M air defense system. Developed in the late 1990s. "Cheetah-3"- a variant of the export TFR on the basis of pr.11660 - instead of the air defense missile system and the ZAK, the installation of the aft and bow combat modules of the ZRAK "Kortik" was proposed. The length of the hull is increased by 13.8 m. The displacement is up to 2100 tons. ZRAK "Kortik" (according to the original project), a helipad above the compartment of the towed GAS. Developed in the late 1990s. "Cheetah-4"- a variant of the export TFR based on the project 11660 - a platform ship for the installation of weapons and equipment of the customer or a search and rescue vessel. Developed in the late 1990s. "Cheetah-5"- a variant of the export frontier TFR based on pr.11660 - a helipad without a hangar, the composition of weapons systems has been changed. range increased to 6,000 miles (at 10 knots). Maximum speed reduced to 23 knots. GTEs in the propulsion system were replaced by diesels with a total power of 28,000 hp. Developed in the late 1990s. 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 a 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 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.

Ships of project 11661 belong to the category of patrol ships (Russian classification), or frigates (international classification). The code name is "Gepard", according to NATO classification - Gepard. They are designed to combat air, ground, surface and underwater adversaries in the near sea zone while performing combat missions related to patrolling, protecting the country's maritime economic zone and its state border, escorting convoys, single ships, ships, etc.
The Gepard project in Russian shipbuilding is the basis for the creation of a whole series of ships belonging to the frigate and OPV (defender) classes.
Peculiarities.
Project 11661K Gepard 3.9-class frigates, currently being commissioned into the fleet, differ significantly from the first ships of the series in terms of their protection and firepower. Starting from the third ship, a modern universal RK is installed, capable of performing a combat mission to destroy coastal and surface targets located at distances of up to 300 km using several types of high-precision missiles. During the construction of the ships of the project, the latest stealth technologies are used, which significantly reduce the likelihood of detecting a frigate by means of radar observation of a potential enemy.
Design.
All ships of the project have a flat-deck architecture. To increase the survivability of the ship, its hull is divided into ten watertight compartments. Even when two compartments located next to each other are flooded, "Cheetahs" remain afloat, can maneuver and almost completely retain their combat effectiveness.
A two-shaft installation of the CODOG type is mounted on them as the main power plant (GEM). Full speed of the ship is ensured gas turbines, each of them works on its own shaft. All cruising modes are served by a 61D medium-speed diesel engine with a power of 5884 kW. Power supply to all ship consumers is carried out from the (GEM), which consists of three diesel generators (DG) (power of each - 600 kW).
All rooms are equipped with air conditioning systems. The use of the latest technologies allowed:
- significantly reduce the levels of secondary fields, thermal and radar;
- to achieve a decrease in the levels of the ship's fields, electromagnetic and magnetic.
The ships of the project 11661 are equipped with means of ensuring survivability and fire protection. An original solution to the issue of placing a deck-based helicopter of the Ka-28 or Ka-31 type on such frigates has been found. After completing the combat mission, it is placed in the free space between the walls of the aft part of the superstructure. If necessary, the helicopter is covered with a tarpaulin awning. it technical solution allowed not to mount a hangar on the ship. The next stage of modernization of the project, "Gepard 5.3", provides for the placement of a deck helicopter in a stationary hangar.
The electronic equipment consists of the Sigma-E combat information and control system, the Horizon-253 navigation radar, the Positiv-M31 three-coordinate target detection and targeting radar, the MGK-335EM-03 sonar system and many other complexes and systems.
Frigates of the type "Cheetah 3.9" were originally created as a flexible base platform, completed according to a modular principle, which allows us to speak of a significant modernization resource included in the project.
Armament.
Currently, the options for the models of the 11661 project have been worked out, providing:
- the armament of the medium-range air defense missile system "Shtil-1" (missile launchers are placed vertically);
- missile systems "Club-N" and "Caliber-NKE" (vertical placement of launchers and equipment with French-made electronic weapons).
The armament of ships can also be of foreign production. For example, SAM "Dart" (Umkhonto) South African production in versions of radar and infrared guidance with a range of targets up to 12 km. These missiles have already been adopted by the South African and Finnish navies. There is a possibility of strengthening the anti-submarine weapons of frigates at the request of the customer.
The main weapon of the Cheetah 3.9 in the configuration supplied by the Russian Navy is the Kalibr-NK SCRC with two packaged launchers (four containers in each). In front of the ship is a turret gun with a universal gun. Air defense tasks are solved by two paired AUs, instead of which can be used ZRAK "Palma" or its version ZRAK 3R98 with missiles "Sosna-R". The Igla-MK or Osa-MA complexes are used as additional air defense systems. The ship can lay minefields (ammunition - 20 minutes). All naval weapons are capable of performing combat missions in rough seas with a force of up to 5 points.
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 the changes in the claims from the 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 re-arrange 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 impact of the radomes of the antennas to determine the seaworthiness, they created and tested ship model... 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 personnel of the crew were disbanded, the ship was mothballed due to underfunding, and also due to the fact that the customer himself (the Russian Navy) was not completely determined on the various types of 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 according to the project 1124 with the NATO code designation - "Grisha class corvette". They were built in 1970-1980 for the Soviet Naval Forces, which included 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 trials 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.
"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 the established requirements of the Navy 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 living conditions, 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 Sigma-E combat information and control system, which meets all the highest standards of our time. 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).
With the Gepardov base platform, you can go beyond building only multipurpose ships, but you can also build ships with reinforced shock, anti-submarine and anti-aircraft missile weapons, 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.

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 laid under the project 11661K 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 tests 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). The 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.
