pr.09851 "Kalitka-SMP" "Khabarovsk"

"Khabarovsk" No. 09851 nuclear submarine is a new type of special nuclear submarine developed by Russia according to future combat needs. The Belgorod multipurpose nuclear submarine belongs to Antey project 949A (Kursk analogue), which was specially converted to project 09852 specifically for the Poseidon system. The Poseidon full-time carrier is the nuclear submarine of project 098531 Khabarovsk.

A special submarine is a submarine that is different from general-purpose submarines and is used to perform special tasks and has multi-purpose capabilities, such as deep-sea operations, underwater transportation, marine surveys, seabed surveys, hydrological surveys, and special operations. The former Soviet navy and the Russian navy have always attached great importance to special submarines, and have built various types of special nuclear submarines, which are regarded as an important part of underwater power construction and an asymmetric means of occupying underwater advantages.

The 09851 nuclear submarine "Khabarovsk" is an improved design of the 885-type sub-class multi-purpose nuclear-powered submarine that the Russian Navy is building in batches. The Yasen-class nuclear submarine has a displacement of about 10,000 tons, a maximum underwater speed of about 31 knots, an autonomous navigation capacity of nearly 120 days, a dive depth of about 600 meters, 8 torpedo launch tubes arranged at multiple angles, and 8 3-unit vertical launch devices It can launch a variety of cruise missiles with powerful firepower. At the same time, the submarine adopts a variety of noise reduction and sound reduction measures. The noise level is said by some to be equivalent to that of the US Navy Sea Wolf class, with low noise and good concealment.

The basic performance of the "Khabarovsk" is not much different from the Yasen-class nuclear submarine, but as a special nuclear submarine, it pays more attention to multi-purpose capabilities and combat capabilities, has a higher degree of automation, and is equipped with richer equipment, including the Arctic. Unmanned submarines and "Poseidon" nuclear torpedoes operating under the ice.

Usually, new types of special nuclear submarines are cruising in the safe waters, using various unmanned submarines and equipment to carry out various tasks, such as ocean investigation, underwater infrastructure construction, seabed exploration, etc.; in wartime, if it is just a small-scale war The new type of special submarine can use ordinary torpedoes and cruise missiles, which can not only defend itself, but also attack a variety of targets on the surface, underwater and land, and perform a very wide range of campaign and tactical offensive missions.

The project 09851 Khabarovsk and Project 09852 were being followed and talked of as probable launch platforms for the new Status-6 (‘KANYON’) strategic nuclear torpedo. The numbers of the Khabarovsk (09851) and Belgorod (09852) projects differ by only one digit. The main launching platform of KANYON [if any] may be be the new Project 09851 'Khabarovsk' (pr.09851 Kalitka SMP) submarine. The design of this boat is similar to but somewhat smaller than the Project 955 'BOREI' SSBN with was also designed by the famous Rubin design bureau.

The available fragmentary information about the project 09851 says that it is: a large nuclear submarine, a "strategic boat" (the official reference is a reference ). The Internet also refers to the allegedly existing silhouette of Khabarovsk on a small series of souvenir pens officially released to its bookmark ( link ). Add to this the information that the developer of the submarine is supposedly the SPBMM "Malakhit" and the laying of the main submarine was held on July 27, 2014 in shop # 50 of the "Sevmash" (Severodvinsk).

Contract # 120-14 of 03.06.2014 was concluded between OAO "PO" Sevmash "and JSC" CDB "MT" Rubin "to perform part of the ROC "gate-SMP" for the construction of submarines pr.09851 (source). Accordingly, the developer of the PLA is CDB ME "Rubin". Bookmark the head of PLA held July 27, 2014 in the workshop #50 by "Sevmash" (Severodvinsk).

The kalitka, a gate or wicket, is a small door in the fence, intended to enter a fenced area (garden, cottage, warehouse, building, etc.). Most often made of metal and wood, it is widespread in rural areas. Design features of wickets are: simple structure, a minimum of structural materials.

The new Project 09851 'KHABAROVSK' (pr.09851 "Kalitka-SMP") submarine is similar to but smaller than the Project 955 'BOREI' SSBN with was as designed by the famous Rubin design bureau. Certain design features allow estimation of the dimensions of the boat. Working off a similar hull diameter to the BOERI we can estimate the submarine's length as 120m versus 160m for the BOREI. This makes sense as the KHABAROVSK does not require the missile section behind the sail. And it is even possible that it shares many components and even hull sections with the SSBN. The stated displacement of 10,000 tons makes it massive, but is much lighter than the 13,000 ton BOREI.

The television report on NTV, broadcast before President Vladimir Putin's meeting on the development of the defense industry, 'accidentally' showed visual material on the underwater Multipurpose System "Status-6". The top left showed the nuclear submarine being built, codename "Belgorod" Project 09852. To the right, a nuclear submarine being built with codename "Khabarovsk" Project 09851.

Certain design features allow estimating the dimensions of the boat. Assuming a similar hull diameter to the Borei, it may be estimated that the submarine's length is 120m versus 160m for the Borei. This makes sense as the Khabarovsk does not require the missile section behind the sail. And it is even possible that it shares many components and even hull sections with the SSBN. The stated displacement of 10,000 tons is substantial, but rather less than the 13,000 ton Borei.

President Putin’s press secretary, Dmitry Peskov, confirmed that the programs on several Russian TV channels, on the eve of the meeting devoted to the president on defense subjects, showed still- classified weapons systems. "We hope that this will not happen again," - said Peskov, reports "Interfax".

In the structure of the Ministry of Defense, the General Directorate operates a top-secret deep-sea research operation. It is engaged in the training of specialists in the field of deep-sea activities, carrying out research in the field of diving, monitoring the oceans and the search and rescue of wrecks. These submarines are contained in this jurisdiction.

The Khabarovsk was laid down at Russia’s Sevmash shipyards in 2014, and is a heavily modified variant of the Borei-class of ballistic missile subs, altered to be smaller and to carry different armaments. Little other information about the sub has been made available, except that the Navy plans to build four of them.

"Khabarovsk" is scheduled to be launched in June 2020 and will continue to be tested for more than two years to ensure the integration of submarines and unmanned submarines.

H.I.Sutton calls the Khabarovsk-class strategic missile sub “the most enigmatic submarine.” The analyst points out that apart from its ability to carry six Poseidon strategic torpedoes, other details on the vessel or its capabilities “is sorely lacking.” In any event, he suggests that the Khabarovsk “could be the defining submarine of 2020.”

The project 09851 submarine may have nothing to do with the GUGI - most likely, this is a fundamentally new nuclear submarine with the unique GEM and the Feniks PPU. It will become, if not the first submarine of a new generation, then at least a transitional solution between the fourth and fifth. While nothing is known about the development of modular weapon designs for nuclear submarines, work on underwater drones-drones in Russia is in full swing, moreover, testing of these products has begun at least since 2008. With a high degree of probability it can be argued that they will be armed with Khabarovsk. This is a certain combination of “academician Sakharov torpedoes” and modern uninhabited underwater vehicles with different types of payload.

Deputy Director General of Design Bureau Malachite Nikolai Novoselov was the first to mention the development of the so-called underwater drones. These are combat robotic means, which equips a submarine, such as submarine drones. After releasing from it, they can be offline, and then activate at the right time by command. The boat has already gone far for this time, and the drone will remain and, for example, will create the appearance of its presence.

Experts of the operative line telegram channel, considering options for equipping Poseidons with future “intermediate” submarines built on the basis of the Khabarovsk submarine (project 098531) and Belgorod (project 09852), point to such technical characteristics as average dimensions Project 949a hull (length 155 m, width 18 m, height 24 meters, draft 9.2 m), as well as the declared weight and size characteristics of “Doomsday torpedoes” (length 24 m, diameter 1.6 m, weight about 60 tons).

In this regard, Russian experts note that additional radiation protection is necessary due to the radiation-nuclear nature of the electrical installation, space for technological corridors for access to each product and current monitoring of their technical parameters. Additional ballast tanks / conformal tanks are needed to compensate for the “exhaust”. Attention is also paid to reinforcing the hull and armor protection in order to avoid destruction at launch, since under its own power a product with such a mass will not be able to leave the submarine, which means that it needs either a starting engine or the presence of a substantial supply of explosive mixture. And last, according to observers, the total number of products "with the current name" Poseidon "on board each of these submarines is possible in the amount of four, which, "most likely, will be so." However, as of 2020 there was no indication of a second unit having beenlaid down.

“Considering further options for the development of this complex and, based on real impact needs, we can assume that for complete happiness it is necessary to build four more hulls of submarines of a separate special project, but already, taking into account the improvement of the technological base and acquired practical experience, designed to carry 6 products each . Of these carriers, two should be in the Pacific Fleet and two in the Northern Fleet to cover a possible aggressor from “both sides”, ”experts explain. “Thus, we believe that the optimal, based on current tasks and about a 20-year-long prospect, will be the presence of 6 Poseidon carrier boats, three on each ocean fleet in the 1X4 and 2 × 6 variants, that is, in total armed contain 32 combat-ready items, 16 for each fleet, ”they conclude.

The scenario that is more suitable for unmanned nuclear submarines is long-term global surveillance and surveillance. Since there is no one on the submarine, there is no need to worry about the health of the crew. As long as the system reliability and global satellite communication problems are solved, it can be operated in the sea for several years.

EADaily adds that in April 2020, the Sevmash plant in Severodvinsk hosted an official launch ceremony for the first experimental multi-purpose nuclear submarine Belgorod, which carries the Poseidon submarine nuclear drones. The boat belongs to Project 949A Antey (an analogue of Kursk), which was specially redesigned for such drones.

The performance characteristics of the project submarine 09851 Khabarovsk have not been officially disclosed. According to data from open sources, the displacement of nuclear submarines is about 10 thousand tons, speed - 30-32 knots, depth of immersion - 500 meters, autonomy - up to 120 days, crew - at least 100 people.

By 2020 it was reported that the development of “Status-6”, called “Poseidon”, will be put on combat alert in the amount of 32 units, for this purpose it is specially planned to build 8 submarines.
