Delta I (Project 667B Murena)

History of Delta I (Item 667B Murena)

The Soviet Navy expanded significantly after the end of World War II (1939-1945), developing from a relatively limited shallow-water force to a global deep-sea naval force that could compete with Britain, France, and the United States. Delta I class from the early 1970s to It entered service with the Soviet Navy in the early 1990s as a group of 18 ballistic missile submarines.

Their ballistic missiles have a long range, which could prove important in a full-scale war with the West. Construction of the group, which began in Severodvinsk and ended in Komsomolsk in the Soviet Far East, is the successor to the outgoing Yankee I-class ships.

The Soviet government approved the construction of a new ballistic missile submarine (Project 667B "Murena") in 1965, after which work began, before the "K-279" was the first submarine launched in December 1972 and 10,000 tons of soaking. She has a length of 456 feet, a beam of 39.3 feet, and a draft of up to 29.5 feet.

Power is provided by the nuclear installation through 2 pressurized water-cooled reactors, which fire 2 steam turbines, which in turn drive a pair of shafts rated at 52,000 hp aft. Surface speeds reach 12 knots, while underwater speeds exceed 25 knots. The diving depth reaches 390 meters. Due to the use of nuclear fuel, the range is essentially unlimited, limited mainly by on-board food supplies and crew fatigue. The crew size is 120 employees.

Her external configuration is mostly traditional, although her sails are well placed forward on her spine and her dive plane is mounted on the tower.

The Delta I class is capable of launching 12 x R-29 "Vysota" (NATO: SS-N-8 "Sawfly") Submarine Launched Ballistic Missiles (SLBM) through D-supplied launch tubes. The 9 Series deploys the ship's spine, Located at the rear of the control tower.

In addition, the class is equipped with 4 x 533 mm (21 in) torpedo tubes on the bow. Missile weapons give the Delta-I the ability to engage land-based enemy targets at long range, allowing the ship to operate enemy sonar traps beyond known ranges. In addition, these ships can fire missiles while moving, albeit at a slow speed of about 5 knots, and still move, adding a "shoot and glide" capability, and tracking is provided by a more advanced navigation system.

Half of the 18 Delta I ships that were eventually built were discontinued in 1991. The remaining ships began decommissioning in 1994, were all out of service by the end of 1998, and faced a crippling torch for the next decade.

Delta I-class submarines were eventually replaced by four-man Delta II-class submarines, which were more or less makeshift ships based on Delta Is - their hulls were lengthened, four missile tubes were added, and their crew strength rose to 130 . The boat is heavier and the diving depth is 450 meters deeper. Work on these new submarines ran from 1972 to 1975, and the line was active until decommissioning in 1996.

The design of the 667B Murena project ship was not exported to Soviet-allied customers.
