    ballistic missile submarines R-29 (SS-N-40) The world's first sea-based intercontinental ballistic missile became BR R-29 (SS-N-40, 4K-75). Its development began in KB V. Makeev by Council of Ministers Resolution № 808-33 of September 28, 1964. Since the range of the new missile was about 8000 km, there was no need patrol SSBN directly off potential enemy, in its effective range of the ASW. Envisaged the possibility and surface-launch, launch missiles could theoretically be produced directly from the pier without departing boats at sea.

    first phase of testing took place with complex floating stand on the Black Sea Navy pilot basis. Was made 7 starts, six of them successful. Subsequently, trials were transferred to the State Central Marine testing ground for developing missile launches from the ground stand. During one of the triggers explosion rocket test had to be interrupted to restore mine and launcher. During the period from March 1969 to November 1971 was made 20 starts from the ground stand.

    third phase of testing consisted of missile launches from the submarine. September 22, 1964 the Council of Ministers issued a decree according to which the project should be developed in the modernization of the submarine submarine pr.658 pr.701 proovedeniya for missile tests and the project of modernization of all submarines pr.658 with the aim of location of the D-9. Conversion at the end of 1964 was allocated PLRB pr.658 K-145. The modernization of her six launchers mounted 4C-75-1. Despite the fact that by the end of March 1971 the boat has been factory tested, rockets are not utilized as ground tests were completed only in November of the same year. First start with a boat on 25 December 1971. Since the White Sea was covered by ice, produced starting from a surface position. During the fifth launch rocket exploded at the exit from the mine. The boat was damaged left for repair at Sevmash, where he remained until August 3, 1972. August 21 of the same year was done six starts. He and all subsequent including salvo was successful. This phase of testing was completed November 28, 1972, was made just 13 starts. December 19, 1976 K-145 upgraded to pr.701 joined the Navy. The remaining submarines pr.658 it was decided not to upgrade. In parallel, according to the same resolution CM CB "Malachite" went DPLRB pr.601 design. The project involved upgrading submarine pr.629. D-9 complex. This project has been converted only one submarine K-118, put her six missiles R-29. K-118 upgraded project 601 joined the Navy December 28, 1978. On December 27, the Navy became the first SSBN pr.667B K-279. During flight tests of these boats was zapushchenno 19 missiles (13 missiles with K-118 and K-6 279), 18 runs were considered successful. K-279 performed two volleys. Four - and dvuhraketny. Including three rockets were launched at full range. Start is from the Barents Sea. The aim was ground in the central Pacific Ocean.

    According to test results, based on the decision of the Council of Ministers № 177-67, March 12, 1974 missile complex D-9 was adopted for use. Supposed to be equipped with missiles submarines Project 667B (NATO classification - "Delta-I"). The boat was carrying 12 missiles pr.667B against 16 per SSBN pr.667A. But despite the decrease in the number of missiles, combat effektivnostpo experts risen 2.5 times. Prior to 1977, was built 18 SSBN 667B project.


    complex D-9, in order to increase the firing range has been upgraded. In 1978 we created the D-9D with rockets P-29D . Firing range was 9100 km. This complex was mounted on the portion 667B and PL projects 667BD.

    On the basis of the RSM-40 missile launcher created "Height", capable of outputting to a circular orbit a payload of up to 115 kg.

    the west range was designated SS-N-8 "Sawfly" mod 1 and mod 2 for D-9 and D-9D, respectively.


    ballistic missile submarines R-29 (SS-N-40) The R-29 with two levels, close coupled.

    Among the many problems that have arisen in the development of the D-9 were the most difficult: the achievement of acceptable size rockets with significant growth performance characteristics, the creation of new small launchers and qualitatively new propulsion systems, substantial progress in combat units , airborne and shipboard control systems, automation services, training and launch missile salvo firing of ammunition, missiles implementation factory filling fuel tanks with ampulizatsiey, operation fleets tucked missiles, providing all-weather combat use and ready for use at any time, anywhere in the world's oceans and etc.

    main decision to drastically reduce the size rocket, was the introduction of "recessed scheme" propulsion system - the location engine fuel fuel or oxidizer. It led to a reduction in the dimensions of the rocket, a rocket elimination dry compartment for accommodation propulsion engines have been created new class: no maintenance after manufacture, without any detachable joints and at the same time having a higher level energomassovyh characteristics. Significant gain given solutions welded hull multistage rockets, placement steering gear component fuel use "wafer" shells, creating one-piece adapter from steel elements of the engine to the aluminum body rocket, as well as addressing swing combustion chambers located in the fuel component.

    Separation was carried out rocket stages break elongated body detonating charge.

    upper bottom of the tank had conical recess, which housed the warhead with a charge capacity of 1 Mt. YABCH was as if turned to the direction of flight. As a measure to counter missile defense systems in the bottom of the tank of the second stage, special cylinders were decoys had effective surface scattering (RCS) is comparable to the EPR warhead. This decision on the sea-based BR applied for the first time. Release decoys separation occurred at the head portion.

    In developing fundamentally new compact housing missiles capable of withstanding elevated overload and excessive external pressure, set the stage for the design of new missile-launching systems in a joint arrangement and rocket launcher.

    The design of the launcher were put innovative solutions:

    instead of hard mounting missile silos it relatively freely in the mine was suspended by elastic links with non-linear power characteristics, with respect to fluctuations allowed the operation of the mine;

    instead of passing on the rocket as point loads through special forces unit was requested to distribute these forces on several annular zones located at different levels along the length of the rocket, with rubber shock absorbers;

    instead of sending the rocket during loading and start with a pair of yoke-guide was used for these purposes or the inner wall of the shaft, either directly rocket shell.

    total effect was very high. Annular gap and the mass launcher decreased by order, and accordingly rocket had risen to the sizes of the silo; huge tank annulus fell many times, and filling the annular gap is no longer limit the prelaunch time, resulting in reduced poslestartovy imbalance submarine and its influence on the rate.

    principal marine missiles were high precision shooting and training flight mission when shooting in any direction, at any time, from anywhere in the ocean within reach of missiles. The peculiarity of this problem - specific requirements for management systems for marine complexes launch rockets with movable base with nonzero initial conditions under very adverse dynamic characteristics of the missile as a control object. When this complex must have all-weather and invariance properties to the start, as well as within certain limits, to the knowledge of the azimuth direction exactly. Control equipment must also provide virtually automatic execution of routine inspections, prelaunch and launch all the missiles, designed for launch (to complete ammunition boats).

    In 60 years, attempts to solve assigned to the control system functions and tasks using analog equipment, as well as the level of development of navigational support submarines leaves no hope for a successful implementation and realization of acceptable precision shooting for intermediate, and even more intercontinental-range shooting. The solution was found.

    successful solution of technological and production problems which allowed us to develop and implement a factory charge and ampulizatsiyu missiles, advanced methods of forming and machining "waffle" skins and other body parts of missiles, TIG and electron beam welding, durable, tight junctions of dissimilar metal, high-performance composite materials, contributed close interaction with developers Zlatoust Machine-Building Plant (Director VN Konovalov and VH Doguzhiev), Krasnoyarsk Machine-Building Plant (Director VP Kotelnikov and VK Gupalov), Omsk Aviation Plant (Director SS Bovkun).
