An important place in the system of strategic deterrence of the most probable enemy is occupied by nuclear submarines carrying ballistic missiles on board, each of which, individually, is capable of wiping out an entire densely populated city from the face of the earth. Today Russia is among the countries with the largest and most modern fleet of nuclear submarines. The submarine of Project 941 "Akula" has been and remains the absolute record holder among them for a number of parameters.
It was the 1970s in the courtyard of the year in the United States, thinking about the creation of third-generation nuclear submarines. In 1976, the Ohio series was developed. The Americans laid the first submarine at the shipyard in 1980. Until now, these submarines form the backbone of the American offensive nuclear fleet. In total, overseas partners acquired 18 such submarines: 14 carry nuclear weapons, and 4 more - cruise missiles. In the USSR, the project "Ohio" was answered with the project 941 "Shark".
It was decided to create fewer submarines than the Americans, while the Akula submarines were to become noticeably larger and carry more nuclear missiles at a time. If the displacement of "Ohio" was 16.7 thousand tons. That Soviet "Shark" had a displacement of 23.2 thousand tons. The latter makes these submarines the largest in the world to this day. A total of 6 submarines were created. The collapse of the Soviet Union prevented the project in many ways. In this case, one of the submarines is a prototype. In the 1990s and 2000s, 3 unique submarines were scrapped. Another 2 remain in reserve to this day.
The well-known Soviet nuclear-powered submarine designer Sergei Nikitich Kovalev supervised the creation of the "Sharks". The work was carried out within the walls of TsKBMT "Rubin". The created submarine operated on two water-moderated nuclear reactors OK-650VV with a total output of 380 MW. The reactors set in motion 2 turbines with a capacity of 50 thousand hp each, and they, in turn, rotated two propeller shafts with 7 propellers 5.5 meters in diameter each. On the water the nuclear submarine "Akula" accelerates to 12 knots, and under water it reaches a speed of 25 knots (43 km / h). The maximum immersion depth is 500 meters. The submarine is operated by a crew of 108 sailors and 52 officers.
The Akula submarine is armed with six 533 mm torpedo tubes. The ammunition load is 22 torpedoes. The air defense system is provided by 8 Igla MANPADS. But the most important thing at Akula is, of course, nuclear weapons. The old Soviet submarine can simultaneously carry 20 R-39 or R-30 Bulava ballistic missiles.
