    ballistic missile submarines p-29R (SS-N-50) In the early 70-ies in KB Academician Vladimir Makeev in response to the deployment of U.S. sea-launched ballistic missiles with multiple warheads ( HSR) was launched experimental development of two offshore missiles with intercontinental range Accuracy: RSM-50 liquid and solid-RSM-52. In the RSM-50 (R-29R, 3M40), its control system and missile system used schematics, design and technological solutions, and verification testing of the past on the R-29 (SS-N-40).

    complex with D-9P missile R-29R was created in a very short time, less than four years, which allowed the Navy to begin deployment of missiles with intercontinental range and MIRV for two or three years earlier than abroad. Subsequently complex with RSM-50 missile repeatedly modernized, resulting warheads were replaced by more advanced and extended terms of their operational use. First a new missile system provided for the formation of any number of missile volley that was very important operational and tactical circumstance.

    missile RSM-50 was intended for weapons SSBN project 667BDR (NATO classification - "Delta-III", under START-1 - "Squid"). Head Boat K-441 went into service in December 1976. Between 1976 and 1984 the Northern and Pacific fleets received 14 submarines of this type with a set of D-9R. Nine of them are in the Pacific Fleet, and five of "squid" one of the Northern Fleet was decommissioned in 1994

    joint flight test R-29R conducted from November 1976 to October 1978 in the White and Barents seas to the head boat K-441. Total was launched 22 rockets, four of them in monoblock six in triblock and 12 semiblochnom equipment. Positive test results allowed to adopt a missile with MIRV missile as part of the D-9R in 1979.

    Based BR R-29 was created three versions: P-29R (triblock), R-29RL (close coupled), P-29RK (semiblochnaya). Later variants of semizaryadnogo refused, mainly because of the imperfect system of breeding warheads. At the moment the missile is in service with the Navy in the optimal configuration for her triblock.

    On the basis of the R-29R created booster "Wave".

    the west range was designated SS-N-18 "Stingray".

    Composition

    ballistic missile submarines p-29R (SS-N-50) Launch located on nuclear submarines of Project 667BDR gun with 16 missiles. New technical solutions implemented in the rocket:

    creating MIRV individually guided warheads to targets;

    the possibility of equipping missiles different models of warheads;

    use system complete celestial and a significant increase in precision shooting;

    creation of high-speed small warheads with small dispersion endo.

    Start

    missiles can be made from the provisions of the submarine and surface submarine.

    two-stage rocket R-29R is based on "sealed" scheme "recessed" fuel propulsion. Housing first and second stages consist of tank shells waffle design made of aluminum-magnesium alloy, double-layer and single-layer intermediate front and back of the bottoms. As the first stage of the power plant used diblock engine, consisting of a stationary base unit and two placed in gimbals, cameras steering unit. In the second stage applied housed in single chamber engine gimbals. Efforts to control pitch and yaw channels are provided in the respective engine swing plane and via heel - the redistribution of exhaust gases through the turbopump assembly roll control nozzle.

    stage rocket separated energy gas pressurization of the first stage, rigid links between steps removed elongated detonating charge. Engines run on both stages unsymmetrical dimethyl hydrazine (UDMH) and nitrogen tetrakside (AT). Top end of the fuel tank of the second stage is in the form of the cone, which houses the military level. Fuel tanks are charged with the factory, and then rocket ampuliziruetsya. Missiles can be launched from a submerged position as well as a surface position.

    Autonomous inertial control system with equipment celestial flight path configured in the nose of the rocket in a sealed instrument compartment Resettable flight astrodome. Application complete rocket systems celestial, and taking into account the compensating errors submarine navigation system in determining the course and location shoots submarine, provided a significant increase in accuracy. At the first stage of the missile to the target separates the first stage, followed by a celestial session, then there is a separation of the second stage, target separation of warheads and their entry into the atmosphere.

    Instrument compartment structurally divided into two compartments sealed bottom. In the first compartment placed triaxial gyrostabilizer with astroviziruyuschim device. Equipment management system is mounted on the frame without the use of individual items of equipment depreciation, and the frame is attached to a frame of the instrument compartment on the shock absorbers. Such a method of installation of devices allowed to increase the density of their arrangement in the instrument compartment.

    The structure includes combat stage liquid propulsion system, payload bay with warheads and instrumentation compartment, which houses the equipment management system, providing individual guidance units for various purposes. To overcome missile defense opponents combat step can be completed with decoys. In the combat missile compartment can be placed three nuclear warheads with a capacity of 200 kt or seven warheads capacity of 100 kilotons each capable of reliably hitting area targets at ranges up to 6,500 km. One missile is capable of striking at the same time on 112 goals.

    Engine compartment

    combat stage includes four-chamber liquid-propellant engine, fuel tanks, body and provides guidance on each block individually target located in the area of considerable radius. On the outside of the casing installed in the stabilization planes of the nozzle and combustion chamber of the engine, and with an internal - combustion cans manufactured in the form of a torus portions. Control elements of the engine and steering gear arranged in the central part of the bay. The engine is made by an open circuit with turbopump fuel feed system. Office for pitch and yaw channels provided redistribution rods camera pairs lie in respective planes stabilization.

    In the combat compartment

    placed warheads, frame, cable network device mounting and separating warheads, and he is in the volume defined by a concave upper bottom of the fuel tank of the second stage. Warheads mounted on the frame and separated by a command from the flight control system. Instrument compartment management system - interchangeable. Replacement warheads and instrument compartment provided if necessary and without unloading rockets from the mine.

    tests and operation

    1 October 1999 missile submarine of the Northern Fleet project 667 BDR under Captain 2 rank Tagira Kayaev from the Barents Sea produced launch RSM-50. The aim was to study the possibilities start extending the service life of missiles of that type. According to the press service of the Navy, the RSM-50 has been undermined by the estimated height, however, according to experts, was caused by a rocket blasting technical problems. From the Sea of Okhotsk fungible submarine of the Pacific Fleet (PF) under the command of Captain 1st Rank Vladimir Bobkov launched missile RSM-50, the head of which is the estimated time to hit the target range Kanin. October 2 missile PAC "Petropavlovsk" the same project 667 BDR under Captain 2 rank Nikolai Evmenova launched missile RSM-50, the head of which has also been successfully achieved landfill Kanin. According to the Navy Commander "defeats the purpose of accuracy in 2 times higher than the standards set for the" excellent ". Such massive ballistic missile tests - an unprecedented event in the history of Russian strategic nuclear forces.
