Why can a crew member predict the sinking of the nuclear submarine Kursk?

Every time the submarine dives, the crew will pray. There is a small launcher in the escape capsule. As long as something happens to the submarine, it will automatically launch. It's full of suicide notes The safety of submarines is worse than that of airplanes, which can skydive. The former are all dead after an accident, so it is not what the crew can expect, but that they have already prepared psychologically, and maybe their lives will be in danger.

Nuclear submarine, referred to as nuclear submarine, is a submarine powered by nuclear reactor. Due to the production and operation cost of this submarine, plus the volume and weight of related equipment, only military submarines use this power source. The first nuclear submarine in the world was the Nautilus of the United States, which began its trial voyage from June 65438 +0957 65438+10/October 65438 +07, announcing the birth of nuclear-powered submarine. At present, there are six countries in the world that openly claim to own nuclear submarines, namely the United States, Russian Federation, China, Britain, French and Indian. Among them, the United States and Russia have the most nuclear submarines. The emergence of nuclear submarines and the application of nuclear strategic missiles have brought the development of submarines into a new stage.

According to different tasks and weapons and equipment, nuclear submarines can be divided into the following categories:

1, attack nuclear submarine, which is a kind of nuclear submarine with torpedo as the main weapon, used to attack enemy surface ships and underwater submarines;

2. Ballistic missile nuclear submarines, with ballistic missiles as the main weapons and torpedoes, are used to attack strategic targets in self-defense;

3, cruise missile nuclear submarines, cruise missiles as the main weapon, used to carry out campaigns and tactical attacks.

4. The experimental purpose is the same as submarine, as a platform for special operations and equipment experiments.

Countries with nuclear submarines in the world: the United States, Britain, Russia, France, China and India. Among them, India just built a nuclear submarine in 2009. There are two kinds of nuclear submarines: one is a strategic nuclear submarine equipped with strategic ballistic missiles, which is used to combat nuclear war and is a strategic deterrent. One is to attack nuclear submarines, which can be used in various operations. The main tasks are anti-submarine, anti-ship and conventional precision strikes on land. Due to the powerful power of nuclear weapons, the countries that originally possessed weapons (that is, the United Nations, which was formed after five victories in World War II) restricted other countries from manufacturing and exporting nuclear weapons technology. Japan, Germany, Italy, Sweden and so on. It was absolutely capable of building a nuclear submarine, but it was abandoned because of World War II or because the United States undertook a defense mission. So they won't develop nuclear submarines. At present, the most advanced technology for attacking nuclear submarines and strategic nuclear submarines is the United States, that is, Ohio-class nuclear submarines (silent, with bomb load, carrying the Trident 2 missiles with the highest range, power and accuracy in the world, and 24 Trident 2 missiles, each of which can carry a 12 missile head at most) and attacking nuclear submarines are famous Wolff-class and Virginia-class, which are ultra-quiet (even lower than the marine background noise) and well-equipped. Britain's nuclear submarine technology is also the top in the world, and the avant-garde strategic nuclear submarine is not as big as the famous Russian typhoon-class strategic nuclear submarine (the avant-garde is 16 missile and the typhoon is 20 missile). However, the missile equipped by the vanguard is the American Trident 2 D5 missile, which has a range of nearly 4,000 kilometers over the typhoon SS-N-20 missile, reaching12,000 kilometers, with higher accuracy. Of course, in terms of overall power, the typhoon level is greater because Russia is equipped with more nuclear warheads. There are also the world's top British attack nuclear submarines, such as the top alert level and ultra-quiet nuclear submarines (even lower than the ocean background noise). In addition, most British attack nuclear submarines are equipped with Tomahawk conventional long-range cruise missiles, which can accurately strike land targets. At present, it is Tomahawk 4, with a range of 2,800 kilometers. It can hover over the target area for about 2 hours (460 kilometers), with two-way communication and fast mission planning. British military technology is very strong, especially the special relationship with the United States, which makes British military enterprises participate in the development of high-tech armaments in the United States. For example, BAE Systems, the world's largest defense company, also participated in the development of F22 and F35. This year, BAE Systems has defeated Boeing and Lockheed Martin to become the largest military enterprise in the world. Russian nuclear submarines mainly win by quantity, which is technically worse than the West. The failure of the latest missile, the round hammer missile, makes the God of the North Wind, the latest Russian strategic nuclear submarine, an empty shelf, which has not been built and put into use so far, and so does the latest attack nuclear submarine, the North Devinsk.
