Why do submarines use nuclear What is the role of nuclear submarines?

Submarines work under water, and if with conventional fuel it is necessary to solve the problem of oxygen **, nuclear reactions do not require the participation of oxygen. The working environment of aircraft and aircraft carriers is in direct contact with the air

Aircraft carriers also use nuclear !! It is not necessary to worry about the aircraft because the space on the aircraft is too small and there are many safety considerations, so this technology has not yet been implemented. The reason for using nuclear power is that it can provide power uninterruptedly, unlike conventional power, which needs to be replenished, and there is something as big as an aircraft carrier, if you use conventional power, how much energy will it consume!

The daily electricity consumption of an aircraft carrier can last a medium-sized city for about a year.

First of all, to correct one place, aircraft carriers also have nuclear-powered ones, such as the "Nimitz" class nuclear-powered aircraft carriers.

Secondly, it will tell you why the aircraft is not nuclear-powered, because nuclear-powered devices are very bulky and need to overcome greater gravity to do work.

The use of nuclear power can greatly enhance the concealment ability of submarines, and submarines can avoid the need to float within a certain period of time to recharge the batteries that keep them moving, as is the case with conventional submarines. At the same time, it is possible to sail for a long time at higher speeds.

There are also many nuclear-powered aircraft carriers, such as the Nimitz-class of the United States. Cruisers are also nuclear-powered, such as Russia's USS Peter the Great (Kirov class), which the United States once built and sailed around the world with the nuclear-powered aircraft carrier Enterprise.

There were countries that tried to give aircraft nuclear power, but the attempt was unsuccessful and abandoned.

Nuclear submarines can be divided into the following categories according to the difference in tasks and equipment:

1. Attack nuclear submarine, which is a kind of nuclear submarine with torpedoes as the main one, which is used to attack enemy surface ships and underwater submarines;

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

3. Cruise missile nuclear submarines, with cruise missiles as the main one, are used to carry out campaign and tactical attacks.

4. Nuclear submarines for experimental purposes are used as platforms for special operations and instrument and equipment experiments.

The role of nuclear submarines is military.

A nuclear submarine is a type of submarine that refers to a submarine designed to be powered by a nuclear reaction. Due to the cost of production and operation of such submarines, as well as the size and weight of related equipment, only military submarines use this power**.

1. The underwater endurance of the nuclear submarine can reach 200,000 nautical miles, and the self-sustaining power can reach 60-90 days. The world's first nuclear submarine was the USS Nautilus, which began its first sea trials on January 24, 1954, announcing the birth of a nuclear-powered submarine. There are 6 countries in the world that openly claim to have nuclear submarines, namely:

United States, Russia, United Kingdom, France, China.

2. The nuclear submarine can sail underwater for a long time, has good concealment, can suddenly attack the target, and the speed of navigation is fast (more than twice the speed of ordinary submarines), so it can track and pursue enemy submarines in time.

3. After the nuclear submarine is equipped with missiles and torpedoes, its attack capability will be greatly enhanced, and it can not only display its prestige underwater and carry out anti-submarine warfare, but also be used to attack the enemy's strategic targets on land, such as transportation hubs, airports, and industrial centers.

4. Among them, the United States and Russia have the most nuclear submarines. The emergence of nuclear submarines and the use of nuclear strategic missiles have brought submarine development to a new stage. A nuclear submarine with a nuclear strategic missile is a nuclear force of underwater deterrence.

The distinction between nuclear and conventional submarines is as follows:

Nuclear submarines refer to nuclear-powered submarines, and conventional submarines refer to conventionally powered submarines, and the two are indeed distinguished by different powers, nuclear submarines use nuclear reactors as power to drive steam engines and generators, and conventional submarines are driven by diesel engines (including diesel generators).

2. The difference in displacement:

Nuclear submarines usually have a larger displacement, and nuclear submarines are generally more than five or six thousand tons, while conventional submarines are usually less than three thousand tons.

3. The difference in power:

Advantages: long endurance, high power, high speed, can carry out a variety of different tasks;

Disadvantages: high noise, large displacement, limited activities, high cost (especially high cost of decommissioning and dismantling), and complex maintenance.

Compared with traditional conventionally powered submarines, nuclear-powered submarines have large power output, high power endurance, and can operate for more than 10 years with nuclear fuel at a time, which is greatly increased compared with conventionally powered submarines of only a few weeks or months, so they are also usually regarded as unlimited endurance forces.

At the same time, nuclear submarines have the advantage of high underwater speed. However, nuclear-powered submarines also have disadvantages, such as technical difficulty, poor stability, high construction costs, high noise and high maintenance requirements.
