PLAKR K-410 “Smolensk” pr.949A in floating dock PD-1 (captured German floating dock divided into 2 PDs)

Nuclear submarine with anti-ship cruise missiles (SSGN).  The project was developed by the LMPB “Rubin” under the leadership of the chief designer P.P. Pustyntsev, the chief designer for the Granit missile system – V.N. Chelomey.  In August 1977, after the death of Pustyntsev, I.L. Baranov became the chief designer.  Deputy Chief Designer – O.A.Gladkov (1983).  The 949A project was a development of the 949 project with an additional hard case compartment and an updated layout.  The initial plans provided for the construction of a large series of 20 SSGNs of project 949 – taking into account the two built SSGNs of project 949, it is likely that a series of 18 SSGNs of project 949 was being built.

On December 30, 1980, the head SSGN pr.949 K-525 was accepted into the USSR Navy, and the Granit missile system was adopted by the USSR Navy by the Decree of the USSR Council of Ministers of March 12, 1983. The head SSGN of the new pr.949A – K-148 –  laid down in workshop No. 55 of the Production Association “Sevmash” on July 22, 1982. The boat was withdrawn from the workshop and launched on March 3, 1985 and became part of the Fleet on September 30, 1986.

The boats of the project in the Navy have the unofficial name “Baton” – for the shape of the hull and the impressive size.

The fencing of retractable devices has a length of 29 m. It contains a pop-up rescue chamber (designed for the entire crew of the submarine).  Also in the fence are 2 VIPS devices for firing sonar countermeasures and containers with missiles for the Igla-1 MANPADS.  The light hull of the boat is covered with an anti-hydroacoustic coating.  A degaussing device is located along the light body.

The SSGN pr.949A differs from the SSGN pr.949 in an additional compartment of a strong hull, as well as a swept keel with an antenna container of a towed sonar of the “Pelamida” type.  The length of the strong hull of the project boats is 10 m longer than the length of the strong hull of the SSGN project 949.  The dimensions of the submarine rudders are larger than those of Project 949.

Means of rescue – a pop-up rescue chamber is installed in the cabin fence, accommodating the entire crew of the SSGN.

The propulsion system is unified with the remote control SSBN project 941 and is completely identical to the remote control SSBN project 949, has a block design, is made with a two-stage damping.

As of 2009, the possibility of using a special launch cup-liner in the SM-225A launcher for two 533 or 650 mm caliber missiles (Onyx, Caliber, etc.) was also discussed (in specialized media).  Presumably, the liner glass could be installed in the Granit missile launcher without altering the launch container, with the electrical connectors matching.

The SSGN is equipped with a system for routine and launch maintenance of the missile system with tanks for replacing the negative buoyancy of fired missiles and the corresponding drainage and air systems.  The system of compensation tanks ensures that the boat is in a given depth corridor when launching missiles, as well as in an emergency when filling the annular gap of four anti-ship missile containers from both sides.  Replacement tanks for negative buoyancy (CZOP) and lost positive buoyancy (CZPP) are located under the strong hull of the boat in the double-board space.  The underwater launch of the missiles was carried out after filling the annular gap in the containers with outboard water with the displacement of air from the annular gap into the compartment.  For the entire period of operation of the SSGN pr.949 / 949A, a full salvo in 24 Granit anti-ship missiles was never fired.

Shipborne automated control system (KACS) 3R45 “Granit” – provides the use of missiles of the 3K45 “Granit” complex – was installed on all SSGN pr.949A.  In 1991, at the Belgorod SSGN (plant No. 664, project 949AM), a decision was made to install KAFU 3R13.9 “Hornbeam” / “Granit-B” / “Granit-Bolid” – ensures the use of the 3K45 “Granit” complex as missiles  “and missiles” Bolid “.  In 2007, it was decided at the Belgorod SSGN (serial No. 664) to bring the KAFU 3R13.9 to an improved modification 3R13.9U to ensure the use of the Granit, Otvet, Caliber, Onyx and Turquoise missiles  , with the possibility of using Bolid missiles in the future.  As of 2009, the possibility of using KAFU 3R14P-949 – a modification of KAFU pr.  .949AM with the installation of this KAFU.

The torpedo-missile weapon system is completely identical to the SSGN pr.949:
2 x 650 mm torpedo tubes
4 x 533 mm torpedo tubes
The torpedo tubes are equipped with an automated quick loader and a mechanized loading device with longitudinal and transverse feed racks.  Control system “Grinda”, designed for centralized automatic control of torpedo tubes, fast loaders.  Fire control system “Leningrad-949”, system of pre-launch preparation and control of missiles, equipment for pre-launch preparation and control of warhead missiles.  Remote control system for torpedoes “Signal-M”.  Code-blocking devices for ammunition with nuclear warheads.  Shooting with torpedoes is possible up to the working depth of immersion at speeds up to 13-18 knots.

Ammunition:
– option 1 – 28 missile torpedoes 83R (10 pcs), 84R (8 pcs), 86R (6 pcs) and 88R (4 pcs).
– option 2 – 28 USET-80 torpedoes (18 pcs), 65-76A (10 pcs).
– option 3 – USET-80 torpedoes (12 / 16 pcs), 86R torpedo missiles (4 / 2 pcs), 83R (10 pcs).

Torpedo tubes with air-hydraulic firing of ammunition of a new design, allowing for salvo firing.  The ammunition storage system uses a fundamentally new automatic adjustment of the position of ammunition on the racks relative to the axes of the torpedo tubes to compensate for the deformation of the strong hull of the submarine when the depth of immersion changes.  With the air-hydraulic method of firing into the breech of the TA from an impulse tank located outside the strong hull of the boat in front of the bow spherical bulkhead, sea water is supplied under excess pressure.  Excessive pressure in the tank is created by the piston of the hydraulic cylinder of the power plant located on a spherical bulkhead inside the first compartment of the pressure hull.  With this method of firing, the magnitude of the excess pressure does not depend on the depth of the submersion of the boat.

2 launchers for MANPADS “Strela-3” / “Igla-1” / “Igla”, ammunition load 10 missiles.  Ammunition is stored in the fence of retractable devices.  According to other sources, the ammunition load is 16 SAM 9M39 SAM 9K38 “Igla” on the K-148 SSGN (serial No. 617), K-173 (serial No. 618), K-141 (serial No. 662), K-150 (serial  .No. 663).
