    In 1958, CDB-18 under the leadership of A. Kassatsiera began work on creating nuclear submarine of the second generation of the project "667A Navaga." The boat was supposed to equip the complex D-4 and D-5 later.

    When creating project boats "667A Navaga" considerable attention was paid to its hydrodynamic perfection. By designing a form, ship industry professionals involved research centers, as well as the hydrodynamics of TsAGI. Carefully worked out the contours of the bow and aft ends, steering gear, steering plumage. Technical design of the boat was approved in 1962

    Increase rocket ammunition required to solve a number of new challenges. In the first place it is necessary to dramatically increase the rate of fire to make it in time to make missile salvo and start to leave the area before it will arrive antisubmarine forces of the enemy. This determined holding simultaneous prelaunch rocket scored a volley. Problem could be solved only by automating all the countdown. In accordance with these requirements for ships project "667A Navaga" under the leadership of RR Belsky turned work on the creation of the first national automated information management system "Cloud". First firing data were generated specialized computers. Navigation equipment of the new submarine was to ensure normal navigation and missile launch in the polar regions.

    front hydroplanes located on the fence cutting. Such a solution, borrowed from U.S. ALL, created the possibility bezdifferentnogo transition to a greater depth at low speeds the boat, as well as simplified retention ship at a given depth in a missile salvo. Stern plumage was made Phillips.

    To reduce the electric field of the ship was first used system of active compensation of the field generated by galvanic couple "screw-housing." Two propellers had low noise level. To reduce the sonar signature foundations for main and auxiliary machinery covered vibrodempfiruyuschey rubber. Durable submarine hull was lined with sound absorbing rubber, and lightweight body was applied nonresonant protivogidrolokatsionnoe and acoustic insulating rubber coating. On the boat project "667A Navaga" was applied AC power system (voltage - 380V), feeding only on stand-alone generators. This increases the reliability of the electricity system, increased the duration of work without repair and maintenance, as well as give an opportunity to transform the voltage to provide a variety of ship consumers.

    The rocket carried

    from flooded mine only submerged boat at sea to 5 points. Originally made four consecutive shooting chetyrehraketnymi volleys. Interval between starts in the volley was 8: calculations showed that as shooting missiles boat should gradually emerge, and after the start of the fourth rocket volley out of the possible "corridor" starting depths. After each volley took about three minutes to return the ship to its original depth. Between the second and the third was necessary volleys 20-35-minute interval for pumping water from the tank into the annular gap missile silos and for trimming the ship. However, the real shooting revealed the possibility of the first eight-rocket volley. The world's first such volley was made December 19, 1969

    new missile in the Navy were called missile submarine strategic (SSBN), which emphasized their difference otPLARB project 658/658M. Its size and power they made a huge impression on the sailors, who had previously dealt with significantly less "solid" nuclear-powered ship 1st generation and "dizelyuhami».

    SSBNs, as well as their predecessors - boats 658/658M project carried on combat duty on the eastern coast of North America, which made them more vulnerable to the rising powers of anti U.S. funds, including sonar system underwater observation, specialized submarines, ships on the water, as well as aircraft and helicopters of the ship and shore-based. Gradually, with the increasing number of ships "667A Navaga" project, started their patrols and the Pacific coast of the United States.

    For its time, this submarine was quite successful in the period from 1966 to 1974 it was built on two major shipyards series (34 units) for the Northern and Pacific fleets. Large underwater speed allowed to move away from the enemy. However, the noise of the boat remained high despite the use of multiblade propellers. It is known that with increasing number of blades the pressure on them is more evenly distributed, making considerable noise appears only at very high speeds.

    significant drawback of this type of missile remained insufficient range of their ballistic missiles. It made choosing patrol areas near likely targets, and thus in front of the coast, which greatly complicates the solution to ensure the sustainability of combat Soviet submarines.

    submarine was under repair in Severodvinsk. August 27, 1968 after modernization works reactor left side due to the spontaneous rise compensating grating on the upper limit switches, power came on, superior rated 18 times. Pressure and temperature in the reactor to exceed the rated values by 4 times. Cause unintended start were incorrect wiring the power supply and human error. The accident resulted in the active zone and the reactor had been destroyed and replaced. Official data on contaminant levels in a submarine environment and personnel exposure levels no.

    subsequently modified project 667AM.

    31 August 1971 missile submarine "K-411", the first time equipped with a special experimental detection equipment polynyas and leads in the ice, reached the North Pole. Within a few hours the ship maneuvered in search of open water, but the two found none was suitable for the ascent, and the boat was forced to return to the ice edge were waiting for a meeting with her icebreaker. Report on the task due to poor permeability of radio waves failed to transmit to the General Staff only after loitering over the point ascent Tu-95RTs (when returning from a mission the plane crashed, performing an aerodrome Kipelovo in conditions of thick fog, the entire crew of the machine, consisting of 12 people died).

    October 3 boat commits patrolling 480 miles northeast of Bermuda submerged, there was an explosion of one of the missiles because in missile silos rapidly began receiving seawater, which crushed the body of the rocket. Ignition of the fuel components led to an explosion. Crew and ship from instant death, probably saved the rugged design of the ship and the fact that a significant proportion of the explosion energy is gone up. Sailors managed to get the submarine to surface, but she sank on October 6. Killed four submariner.
