Submarines of project 667bdrm dolphin. Nuclear submarines of the USSR. way to create submarine missile carriers

The construction of a series of boats was carried out in Severodvinsk by the Sevmash Production Association. The lead boat K-51 (serial number 379) was laid down on February 23, 1981, launched on March 7, 1984 and accepted by the Navy on December 29, 1984.


Design double-hull - based on the design of SSBN pr.667BDR - the height of the missile silo fencing has been increased, a long slotted scupper is placed along the missile compartment, the length of the bow and stern ends has been increased, the sonar fairing is plastic without fins, the diameter of the durable hull has been increased, the contours of the light hull have been “filled up” in the area 1 -3 compartments.

The material of construction of the durable body is steel produced by electroslag remelting with increased ductility.

To level the incoming water flow in front of the propellers, a special hydrodynamic device is installed on the light hull of the boat.

The design of the boat includes measures to significantly reduce noise - local sound absorbers are installed in the compartments with power plant units, the durable and lightweight hull is equipped with a new anti-hydroacoustic coating. In terms of noise level, the boat is close to that of the Ohio-class SSBN (USA).

To improve living conditions, the ship has a solarium, sauna and gym. The system of electrochemical air regeneration has been improved by electrolysis of water and absorption of carbon dioxide by a solid regenerating absorber. The system ensures that the air content of oxygen in the pods is 25% and carbon dioxide is not higher than 0.8%.

Based on the design features of the light hull (at a minimum), the boats can be divided into early and late versions of the project (see the register below). The main visual difference is in the size and location of the slotted scupper in the light hull of the boat.

The last ship of the "667 family", as well as the last Soviet submarine missile carrier of the 2nd generation (in fact, "smoothly transitioned" into the 3rd generation) was the strategic missile submarine cruiser of Project 667.BRDM (code "Dolphin"), as well as its predecessors, created by the Rubin Central Design Bureau for Mechanical Engineering under the leadership of the general designer, academician S.N. Kovalev. The government decree on the development of a new nuclear submarine was issued on September 10, 1975.

The main weapon of the ship was to be the new D-9RM missile system with 16 R-29RM intercontinental liquid-propellant missiles (RSM-54, SS-N-24), which had an increased firing range, accuracy and warhead spread radius. The development of the missile system began at KBM in 1979. Its creators were focused on achieving the highest possible technical level and performance characteristics with limited changes to the submarine design. The assigned tasks were successfully solved through the implementation of original layout solutions (combined tanks of the last sustainment and combat stages), the use of engines with extreme characteristics, the use of new structural materials, improving production technology, as well as increasing the dimensions of the rocket due to volumes “borrowed” from the launcher installations. In terms of their combat capabilities, the new ballistic missiles were superior to all modifications of the most powerful American naval missile system, Trident, while having less weight and dimensions. Depending on the number of warheads and their mass, the firing range of ICBMs could significantly exceed 8300 km.

The R-29RM was the last missile developed under the leadership of V.P. Makeev, as well as the last domestic liquid-fueled ICBM. In a certain sense, it was the “swan song” of liquid-propellant ballistic missiles for submarines. All subsequent domestic ballistic missiles were designed with solid fuel.

The design of the new ship was a further development of boats of the 667 family. Due to the increased dimensions of the missiles, as well as the need to introduce new design solutions to reduce hydroacoustic visibility, the height of the missile silo fencing on the boat had to be increased again. The length of the bow and stern ends of the ship was also increased, the diameter of the strong hull also increased, and the contours of the light hull in the area of ​​the 1st - 3rd compartments were somewhat “filled up”.

In the design of the durable hull, as well as the end and intercompartment bulkheads of the boat, steel was used, obtained by electroslag remelting and having increased ductility.

When creating the submarine, measures were taken to significantly reduce its noise, as well as reduce interference with the operation of on-board hydroacoustic equipment. The principle of aggregating mechanisms and equipment, which is placed on a common frame, shock-absorbed relative to the strong hull of the ship, is widely used. Local sound absorbers have been installed in the area of ​​the energy compartments, and the efficiency of the acoustic coatings of the lightweight and durable hulls has been increased. As a result, in terms of hydroacoustic signature characteristics, the nuclear-powered submarine has approached the level of the American 3rd generation SSBN Ohio.

The main power plant of the submarine includes two VM-4SG water-water reactors (90 MW each) and two OK-700A steam turbines. The rated power of the power plant is 60,000 hp. With. On board the ship there are two TG-3000 turbogenerators, two DG-460 diesel generators, and two economical electric motors.

The SSBN has low-noise five-blade propellers with improved hydroacoustic characteristics. To provide the propellers with the most favorable operating conditions, a special hydrodynamic device is installed on the lightweight body to equalize the oncoming water flow.

Project 667.BDRM implemented measures to further improve living conditions. The ship's crew had a solarium, sauna, gym, etc. at their disposal. An improved system of electrochemical air regeneration by electrolysis of water and absorption of carbon dioxide by a solid regenerating absorber reliably provided oxygen concentrations within 25% and carbon dioxide concentrations not exceeding 0.8%.

For centralized control of all types of combat activities, the boat is equipped with the Omnibus-BRDM combat information management system, which collects and processes information, solves problems of tactical maneuvering and combat use of torpedo and missile-torpedo weapons.

The SSBN is equipped with a new sonar system "SKAT-BDRM", which is not inferior in its characteristics to its American counterparts. It has a large antenna with a diameter of 8.1 m and a height of 4.5 m. For the first time in the practice of domestic shipbuilding, Project 667.BDRM used a fiberglass antenna radome with a ribless design (this made it possible to reduce hydroacoustic interference affecting the antenna device of the complex). There is also a towed hydroacoustic antenna, which retracts into the body when not in use.

The navigation complex "Sluice" provides the necessary accuracy in the use of missile weapons. Clarification of the ship's position by means of astrocorrection is carried out with a subsurface to the periscope depth at intervals of once every two days.

The Project 667.BDRM submarine cruiser is equipped with the Molniya-N radio communication system. There are two pop-up buoy-type antennas that allow you to receive radio messages, target designations and signals from the space navigation system at great depths.

The D-9RM missile system, adopted for service in 1986 (after the death of its creator, Viktor Petrovich Makeev), is a further development of the D-9R complex. It consists of 16 three-stage liquid-fueled ampuled missiles R-29RM (ZM37, RSM-54) with a maximum firing range of 9300 km.

The R-29RM rocket today has the highest energy and mass perfection in the world. Its length is 14.8 m, its body diameter is 1.9 m, it has a launch mass of 40.3 tons and a throw mass of 2.8 tons (equal to the throw mass of the much heavier American Trident II missile). The R-29RM has a multiple warhead designed for four or 10 warheads (power: 100 kg). Currently, missiles with warheads equipped with four warheads are deployed on SSBNs.

High accuracy (COE - 250 m), comparable to the accuracy of the American Trident 0-5 missile (according to various estimates - 170-250 m), provides the D-9RM complex with the ability to destroy small-sized highly protected targets (silo launchers of intercontinental ballistic missiles, command points and other “heavy-duty” objects). The entire ammunition load of a missile cruiser can be launched in a single salvo. The maximum launch depth is 55 m; there are no restrictions on weather conditions in the launch area.

In 1988, the missile system was modernized: the warheads were replaced with more advanced ones, the navigation system was supplemented with space navigation equipment (GLONASS system), the ability to launch missiles along flat trajectories (including from high latitudes) was provided, which makes it possible to more reliably overcome promising missile defense systems potential enemy. The missile's resistance to the damaging effects of a nuclear explosion has also been increased.

According to a number of experts, the modernized D-9RM complex is superior to the American analogue Trident 0-5 in such important indicators as the accuracy of hitting targets and the ability to overcome enemy missile defense systems.

The new torpedo-missile system, installed on the Project 667.BDRM submarine, consists of four 533-mm torpedo tubes with a fast loading system, ensuring the use of almost all types of modern torpedoes, anti-submarine missile-torpedoes and hydroacoustic countermeasures.

The construction of Project 667.BDRM boats began in Severodvinsk in 1981. The fleet received a total of seven nuclear-powered ships of this type. Captain 1st Rank Yu.K. Rusakov was appointed the first commander of the lead boat - K-51.

In 1990, special tests were carried out on one of the Project 667.BDRM cruisers with the preparation and launch of the entire ammunition load of 16 missiles in one salvo (as in real combat firing). Such an experience was unique both for our country and in the world.

Currently, Project 667.BDRM SSBNs (known in the West under the “nickname” Delta IV) are the basis of the naval component of Russia’s strategic nuclear triad. All of them are part of the 3rd flotilla of strategic submarines of the Northern Fleet and are based in Yagelnaya Bay. To accommodate individual boats, there are also special shelter bases, which are reliably protected underground structures designed for parking, as well as for repairing and recharging reactors with nuclear fuel.

Project 667.BDRM submarines became one of the first domestic nuclear-powered submarines to be almost completely invulnerable in their combat duty areas. Carrying out patrols in the Arctic seas immediately adjacent to the Russian coast (including under ice cover), they, even in the most favorable hydrological conditions for the enemy (complete calm, which is observed in the Barents Sea in only 8% of “natural situations”), can be detected by the latest American nuclear attack submarines of the Improved Los Angeles class at distances of less than 30 km. However, in conditions typical for the remaining 92% of the year, in the presence of waves and wind with a speed of more than 10-15 m/s, the Project 667.BDRM SSBNs are not detected by the enemy at all or can be detected by BQQ-5 type sonar (installed on the Los Angeles ") at ranges of less than 10 km, when further underwater tracking causes an increased risk of boat collision and is equally dangerous for both the “hunter” and the “game”. Moreover, in the northern polar seas there are vast shallow water areas where, even in complete calm, the detection range of Project 667.BDRM boats is reduced to less than 10 km (i.e., almost absolute survivability of submarine missile carriers is ensured). At the same time, one should keep in mind the fact that Russian missile submarines are on combat duty actually in the country’s internal waters, which are quite well (even in current conditions) covered by the fleet’s anti-submarine weapons, which further reduces the real effectiveness of NATO boats.

For almost 30 years, Soviet nuclear missile carriers successfully resisted the nuclear potential of Western countries, playing the role of a reliable element of deterrence. A nuclear submarine armed with ballistic missiles was, is and will be the most powerful weapon in the modern era. Thanks to their great destructive power and advanced equipment, missile submarines are the most advanced warships that have ever left the stocks. The Soviet Union could be proud of its achievements in the field of nuclear submarine construction. Today, the rich traditions of Soviet submariners, all the vast accumulated experience in the construction of ships of this class, are successfully used in practice by Russian submariners. The combat service of Project 667BDRM Dolphin-class submarines is clear proof of this. The missile submarine cruisers “Novomoskovsk”, “Ekaterinburg” and “Verkhoturye” continue to regularly perform combat duty as part of the Northern Fleet.

Seven Dolphin-class nuclear submarines are the basis of the maritime component of Russia's nuclear triad at the moment. These ships are direct descendants of Project 667 nuclear-powered submarines, which were the most popular in the Soviet fleet.

Old, new project 667BRDM "Dolphin" type

The collapse of the Soviet Union left the Russian Navy a rich legacy. A huge nuclear submarine fleet was stationed in bays in the Northern Fleet and was based in the Far East. Soviet nuclear submarines were of different ages and were differently prepared for further service. Of all the types and classes of submarines, the Project 667BRDM nuclear-powered submarines of the Dolphin type are the best preserved. It was on these ships that the bet was placed on the future maintenance of the combat readiness of the Russian naval nuclear forces.

It should be said right away that this project was a hodgepodge, which included the best design developments in the process of building ships of Project 667. As before, the development of the improved project was carried out by the Rubin Central Design Bureau, the flagship of the domestic nuclear submarine shipbuilding.

The Dolphin-class ships were supposed to be the final version of Project 667, marking the transition from 2nd generation nuclear submarines to 3rd generation submarines. According to the Soviet classification, boats of this type belonged to the class of missile submarine cruisers, and accordingly the type of ship was designated as SSBN (strategic missile submarine cruiser). The development of an improved project began back in 1975, when the US Navy began to develop the design of a new Ohio-class nuclear submarine. The new American submarine was planned to carry 24 Trident II ballistic missiles.

The nuclear-powered missile carriers that were part of the USSR Navy at that time were armed with fewer strategic missiles. In view of the current situation and in order to create parity with the Americans in terms of the number of nuclear carriers, it was decided to create a more powerful ship for the fleet. The basic basis for the new Soviet submarines was the Project 667BDR Kalmar submarines. In the design of the new submarine, it was decided to increase everything and significantly improve the navigation characteristics of the underwater vessel. The ships were designed to install the new Soviet R-29RM strategic missiles, so it was necessary to increase the size of the ship. The bow and stern ends of the submarine have increased accordingly.

During the design process, attempts were made to reduce the noise of the ship and make the hydroacoustic image of the submarine less noticeable. Many systems on the Project 667BDRM submarine were used for the first time, including new sonar equipment. The result of the designers' work was an almost new project, which marked the beginning of a new final series of Soviet nuclear-powered missile carriers, consisting of 7 ships.

Design of the Project 667 BDRM nuclear submarine

The lead ship of the series, the nuclear submarine B-51 Verkhoturye, was laid down on the holiday, February 23, 1981. The main enterprise of Soviet nuclear shipbuilding, the Severodvinsk Machine-Building Plant Sevmash, was chosen to build the ships of this project. Over the course of 9 years, from 1981 to 1990, the enterprise launched and commissioned 7 ships of Project 667BDRM. The last ship in this series was the K-407 Novomoskovsk SSBN.

The submarine missile carrier Verkhoturye received a pronounced hump, which housed 16 ballistic missiles. In the NATO classification, the ship received the code "Delta-IV", continuing the series of combat ships under the code Delta. The size of the submarine was impressive. The length of the boat's hull was 167 m, and the displacement increased to 11,740 tons. The nuclear submarine had a double-hull design, which became traditional for ships of previous series. The ship's robust main hull and bulkheads were made of durable steel that can withstand long-term intense loads and has anti-corrosion properties. The design of the ship and the strength characteristics of the materials allowed the boat to descend to a depth of up to 600 m.

The main components and assemblies of the submarine were placed on special shock-absorbing platforms that reduce vibration and acoustic noise. The compartments with the power plant had local sound absorbers. The lightweight hull was covered with a camouflage material specially developed for this purpose, providing a lower hydroacoustic background of the ship. A distinctive feature of the Project 667BDRM submarines were the propellers, which had five blades and had an improved hydroacoustic picture.

Such measures and innovations significantly increased the stealth of the ship, bringing the hydroacoustic parameters of the Soviet submarine closer to those of the American Ohio-class missile carrier.

During combat cruises, the Soviet missile submarine cruisers Ekaterinburg and Podmoskovye managed to remain at sea undetected by NATO ships for more than a week. This was the reason that American submarines were forced to approach the permanent bases of Soviet submarines, exposing themselves to a great risk of being detected.

All ships of the project received an automated weapons control system "Omnibus-BDRM", with the help of which incoming information was analyzed and the parameters of the combat use of tactical weapons were determined. In addition, the boats were equipped with new hydroacoustic equipment “Scat”, which has two antennas. One antenna was located in the nose fairing, the second was used in a towed version. The missile armament had an improved “Gateway” navigation system, which made it possible to accurately determine the location of the boat during missile launch.

The main power plant for all submarines was the VM-4SG nuclear reactor, which provided steam for two OK-700A turbine units. The total power of the propulsion system was 60 thousand liters. With. 225 hp electric motors were used as backup engines on the ships. every. The nuclear installation provided the ships with underwater speed at a speed of 24 knots.

In contrast to the ships of the earlier series, the conditions of the personnel on the Dolphins have significantly improved, ensuring comfortable service during long and long-distance military campaigns. The submarine's crew numbered 140 people.

Firepower of Project 667BDRM missile carriers

The ships were originally designed for the R-29RM ballistic missile. The D-9RM missile system installed on submarines was a launch pad for 16 strategic intercontinental missiles. The Soviet rocket had a significant technological advantage over its American counterparts. In terms of firing range and accuracy of hits with warheads, the R-29RM had no equal. Having smaller dimensions and take-off weight, the Soviet missile could deliver nuclear charges over a distance of over 8 thousand km.

This type of rocket was the last to use liquid rocket engines. Further, all types of missile weapons installed on domestic submarines operated on solid fuel. Over the course of five years, from 1996 to 2001, all ballistic missiles in service with Project 667BDRM submarines were replaced with a modernized version, the R-29RMU2 missile. Subsequently, Russian missile carriers of the Dolphin type were re-equipped to launch R-29RMU2.1 Liner missiles. In 2011, the first underwater launch of a new modernized missile was carried out from the Ekaterinburg SSBN. Following these tests in the same year, the second intercontinental missile of this type was launched from the K-114 Tula nuclear submarine. Project 667BDRM boats could fire a missile salvo while at a working depth of 55 m.

The tactical armament of the Dolphin-class nuclear submarines was represented by four 533 mm torpedo tubes and the Vodopad anti-submarine torpedo-missile system.

Project 667BDRM nuclear-powered missile submarines in the Russian fleet

All seven ships of this project were put into operation in the Soviet Union. At the time of the collapse of the USSR, these submarines remained the most modern and formed the backbone of the nuclear forces of the Russian Navy. All ships were assigned to the Northern Fleet and were based at the Gadzhievo naval base. In the early 90s, a government decision was made to maintain Project 667BDRM missile carriers in combat condition, and with sufficient funding to carry out planned repairs and modernization. The lead boat of the first series underwent scheduled repairs and modernization in 1993, once again entering service with the Northern Fleet. On the remaining ships, starting in 1996, scheduled repairs and modernization were carried out one by one.

The nuclear submarine K-64 Podmoskovye was decommissioned in 1999. The modernization of the ship continued for 16 long years. As a result, the boat was converted into a test ship capable of delivering ultra-small submarines. The ship received a new number BS-64. The ship was commissioned in the Northern Fleet in 2019. On the former missile carrier Podmoskovye, the missile silos were removed and a new compartment for transporting ultra-small submarines was installed.

To date, all ships are in service. A new stage in restoring the technical readiness of all ships is expected to begin. The K-117 Bryansk submarine was the first ship of its class to launch an intercontinental missile over a short distance. In recent years, the ship has repeatedly carried out training and combat launches of ballistic missiles in the Barents Sea.

A strategic missile submarine, the K-18 submarine surfaced at the North Pole, planting the state flag of Russia and the Navy. In 1996, by decision of the Commander-in-Chief of the Navy, the submarine received a new name “Karelia”.

Eventually

All Project 667BDRM ships currently remain in the Northern Fleet and represent the most modern and combat-ready ships of the Russian fleet. Ships of this class have the necessary combat power, being an important component of the Russian nuclear triad. Six missile carriers take turns on combat duty, while the Podmoskovye boat is involved in research programs and projects.

While on combat duty, Russian missile carriers create a lot of problems for search teams of NATO countries. Good stealth and great autonomy provide these submarines with convenient starting positions in the world's oceans. Project 667BDRM missile carriers operate mainly in polar latitudes, where Russian submarines pose a constant real threat to a potential enemy.

Project 667BDRM, like its predecessors, was created within the walls of the Rubin Central Design Bureau under the leadership of general designer S.N. Kovalev.

The design of the new submarine is a further development of the 667 family. It is distinguished from the previous project 667BDR by: the increased height of the “hump” (fencing of missile silos) due to the increased size of the missiles; increased length of the ship's bow and stern limbs; the contours of the light hull in the area of ​​the 1st-3rd compartments were “filled up”. Measures were taken to significantly reduce noise and reduce interference during the operation of on-board sonar equipment. Local sound absorbers have been installed in the area of ​​the energy compartments, and the efficiency of the acoustic coatings of the lightweight and durable hulls has been increased.

The main power plant of the submarine includes two water-water reactors VM-4SG (90 MW each) and two OK-700A steam turbines. The rated power of the power plant is 60,000 hp. On board the ship there are two TG-3000 turbogenerators, two DG-460 diesel generators, and two economical electric motors with a power of 225 hp each.

3.

Project 667BDRM submarines are equipped with low-noise five-bladed propellers with improved hydroacoustic characteristics. To provide the propellers with the most favorable operating conditions, a special device is installed on the lightweight body that equalizes the incoming water flow.

The crew habitats on the submarines of this project have been significantly improved. Submariners had a gym, solarium, sauna, etc. at their disposal. The electrochemical air regeneration and carbon dioxide absorption system has been improved.

New systems:
To centralize the control of all types of weapons, the Omnibus-BDRM combat information and control system was installed. It collects and processes information on solving problems of tactical maneuvering and combat use of torpedo and missile-torpedo weapons.

A new hydroacoustic complex MGK-520 "Skat-BDRM" was installed. In the bow of the ship there is its antenna, the fairing of which is made of fiberglass, which has significantly reduced the level of hydroacoustic interference. There is also a second, towed antenna, which is located at the rear of the ship and is retracted into the hull when not in use.

The Gateway navigation system has been installed, which ensures the required accuracy in the use of missile weapons.

Weapons:
The submarines received new weapons - 16 R-29RM ballistic missiles, which were subsequently replaced by their modification R-29RMU2 "Sineva" during modernization at the Zvezdochka enterprise in 1996-2001. The launch - single and salvo - can be carried out at a depth of up to 55 meters and at a speed of 7-8 knots. In the future, it is planned to re-equip it with the R-29RMU2.1 “Liner”.

Four bow 533 mm torpedo tubes and an ammunition load of 12 torpedoes (533 mm torpedoes SAET-60M, 53-65M, PLUR “Waterfall”).

Project 667BDR submarines are the most successful SSBNs in our fleet and one of the most important parts of Russia’s nuclear triad. Almost all ships are in excellent technical condition, for which each submarine is in average repair. After the repair of the K-407 Novomoskovsk, VTG began.

Currently, the Severodvinsk enterprise “Zvezdochka” has two submarines of Project 667BDRM: K-114 “Tula” - scheduled factory repairs, BS-64 “Podmoskovye” - re-equipment according to Project 09787.
