    submarine 667AM

    Although all domestic first-generation SSBNs were equipped exclusively liquid rockets (which corresponds to the actual level of the Soviet rocket), fleet and industry experts were well aware of all operational deficiencies such missiles. BR with expander is highly toxic and fire explosion hazard. Specificity of their application required in the implementation of underwater launch prefill seawater annulus mines, which created a complex system of pipes and pumps. As a result of pumping large volumes of water during prelaunch increased noise level, unmasking submarine. All these shortcomings were absent in missiles with solid-fuel missiles. Therefore, in parallel with the creation of liquid marine BR in our country in the late '50s and began work on the first solid-fuel missiles to equip submarines.

    In accordance with the Government Order dated September 9, 1958 Leningrad KB "Arsenal" has begun to develop missile complex D-6 with a solid propellant missile, designed to equip prospective missile. Work was carried out on two parallel tracks - the creation of BR with the engine ballistnyh gunpowder, as well as more promising composite propellant. The disadvantage of the first option is the need for cumbersome cords of four engines, which led to excessive growth of the dimensions of the rocket, and the creation of mixed fuel engine solutions require a number of complex scientific, engineering and technological problems, which in the 50s - 60s. were still "not equal to" domestic rocket. Originated and some purely organizational difficulties. As a result, in accordance with the Decree of 4 April 1961 on the program of the D-6 were discontinued.

    The same government decree OKB V. VP Makeev was instructed to begin work on a new solid-fuel "outboard" of the D-7 missile RT-15M (4K-22), focused on new submarine 667-year project. The entire technical documentation developed "arsenaltsev" program D-6, was transferred to the SKB-385.

    RT-15M missile was to have a launch weight of about 50 tons (more than three times the mass of the American BR Polaris A1 and launch range of 2,400 km. Work on complex D-7 were brought to the stage throwing tests, however in 1962, when the customer demanded a sharp increase in ammunition missile (and therefore reduce the size of missiles), interest in the program began to gradually fade away, and in 1964 it was completely stopped due to the inability of developers to meet the scope of the new requirements. At the same time, KB "Arsenal" continued work on the land-based strategic missiles, led to the adoption service in 1972 BR medium range 8K98P. accumulated experience in creating composite propellant motors allowed "Arsenal" to come up with a proposal to develop for the upgraded project SSBN Navaga 667A solid-fuel missile, which could be placed in the mines created for BR R-27. This new missile launch range was 1.5 times higher than the range of its predecessor, approaching features the latest U.S. missile Poseidon C3.


    modernized ship differed from SSBN project 667A Navaga aft superstructure having a slightly smaller length and greater heights. Increased slightly and total displacement of the submarine. The launch was carried out by powder battery from a depth of 50 m, without filling the mine water (which increased stealth combat use, since the flow of water into the annular space ship unmasked during prelaunch). Start was possible at sea to 8 points. All ammunition fired into the one minute one gulp. Prelaunch time was 3.5 min.

    To convert the project "667AM" was singled submarine K-140 - the second ship of Project 667A Navaga. Work to modernize the nuclear submarine began at the shipyard "asterisk" in Severodvinsk in 1973 The first launch of P-31 on board the K-140 was held December 26, 1976 from the White Sea. During the test boat were two firing at maximum range (over 4000 km). To do this, the boat had to go to the northern tip of Novaya Zemlya and thence the parallel of 77 ° north latitude to shoot in combat field "Kura" in Kamchatka.
