What is the depth of the submarine How many meters can a submarine dive at its deepest depth

The ultimate depth of submarine diving, also known as the maximum depth of diving, is the maximum depth of the submarine that can be allowed by the compressive strength of the hull, and the submarine can only stay at this depth for a limited number of short periods.

In addition, the depth at which the strength of the hull is calculated when designing a submarine is called the design depth. It is usually a multiple of the limit depth to ensure that it still has a certain survivability in the water ** near the submarine ** or when the submarine exceeds the limit depth. The maximum depth of the submarine in the First World War.

The period is about 60 to 70 meters; Second world war.

increased to 200 meters during the period; After the war, it was generally 300 400 meters, and some reached more than 900 meters. Ordinary conventionally powered submarines are generally 250-350 meters deep.

There are parts of the double-hull nuclear submarines that can dive to a depth of 500. The main measures to increase the depth of the submarine are the use of high-strength steel and titanium alloys.

In fact, no matter how deep it is, it doesn't make much sense to use new welding technology and pressure-resistant structural forms suitable for deep diving. Every 1 meter of deepening may require several tons of steel, which is more than worth the loss. Because the submarine noise at this depth has already made the vast majority of sonar in service.

No trace of the submarine was detected.

Nuclear power

Nuclear power is another power developed after diesel-electric power. The principle of nuclear power is to make a steam engine through the high temperature generated by the nuclear reactor.

The steam turbine is driven to drive the propeller.

Or a generator that generates power.

The first to successfully install a nuclear reactor on a submarine was the USS Nautilus submarine of the US Navy.

There are five countries in the world that openly claim to have nuclear power, with the United States and Russia using the highest proportions. The United States even announced in 1958 that it would no longer build non-nuclear-powered submarines.

The United States even announced in 1958 that it would no longer build non-nuclear-powered submarines.

Compared with traditional diesel-electric submarines, nuclear-powered submarines have the advantages of large power output, high power endurance (because the fuel replenishment and replacement of nuclear-powered submarines is usually more than 10 years, compared with diesel-electric submarines of only a few weeks or months, it is greatly increased, so it is usually regarded as unlimited endurance), fast speed and so on.

However, nuclear-powered submarines have the disadvantages of high technical difficulty, poor stability, high construction costs, high noise and high maintenance requirements. The advent of nuclear batteries solves these problems and means that submarines with superior performance can be manufactured in batches.

The submarine diving depth is the vertical distance between the surface of the submarine and its ** cabin depth gauge after diving underwater.

The unit of measurement is meters. It is usually divided into periscope depth, danger depth, working depth, limit depth and design depth, etc.

Periscope depth is the depth at which the submarine can use the periscope to observe and work with other lifting devices, usually between 8 and 15 meters; Dangerous depth is the depth range between the periscope depth and the upper limit of the working depth, generally between 10 and 30 meters, this depth is the draft of surface ships, and it is difficult for submarines to observe the sea surface and there is a danger of colliding with other ships; The working depth is the depth between the lower limit of the danger depth and the maximum working depth, and its range is 80%-90% of the limit depth; The ultimate depth is the maximum allowable depth of the submarine hull compressive strength; The design depth is the depth set for designing the strength of the submarine's pressure-resistant hull.

The average conventional submarine is from 200 to 300 meters, and the nuclear submarine can be below 400. The deepest nuclear submarine recorded is the Russian Akula attack nuclear submarine. A total of 5 ships were built.

The deepest dive was 1200 meters. In addition, there are deep-diving robots, which can generally dive below 600 meters. The deepest record is in Japan.

It also dived to more than 1,000 meters.

As of 2021, the maximum depth of the submarine is 10,975 meters (data statistics in 2020).

At present, the deepest submarine known in the world is the Japanese submarine Kaiko, which dives at a depth of 10,975 meters at the bottom of the world's deepest trench "Mariana Trench".

The world's first nuclear submarine was the USS Nautilus, which began its first sea trials on January 24, 1954, and announced the birth of a nuclear-powered submarine. There are six countries in the world that openly claim to have nuclear submarines: the United States, Russia, the United Kingdom, France, China, and India (India's nuclear submarine USS Enemy Destroyer is under construction).

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 limit depth of the submarine is 900 meters.

There are many types of submarines and different shapes, ranging from small civilian submersible probes that are fully automatic or operated by one or two people and operate for several hours, to Russian Typhoon-class nuclear submarines that can carry hundreds of people and dive continuously for 3-6 months.

According to the volume, it can be divided into large (mainly military), medium or small (pocket submarines, submersibles) and underwater automatic mechanical devices.

Large submarines are mostly cylindrical, and a vertical structure (bridge) is usually set up in the middle of the ship, which was called the "control tower and command platform" in the early days, and contained communications, sensors, and periscopes.

and control equipment, etc. Today's deep-sea submarines or specialized submarines are often no longer designed to do so.

Summary. Hello, the submarine dives to a maximum depth of 1250 meters. According to the 2021 query, the maximum depth of the submarine is 1250 meters, and the data is counted in 2020.

The deepest nuclear submarine came from the hands of the Soviet Union, which was the Type 685 attack nuclear submarine developed by the Soviet Union in 1966, and has a relatively long history.

Hello, the submarine dived and cautious to the maximum depth of 1250 meters. In 2021, the maximum depth of the submarine was 1,250 meters, and the data statistics were hidden in 2020. The deepest nuclear submarine came from the hands of the Soviet Union, which was the Type 685 attack nuclear submarine developed by the Soviet Union in 1966, and has a relatively long history.

The Type 685 attack nuclear submarine adopts a droplet line type, a spherical head, and a drop-shaped pointed tail, but it is slightly different from the drop-type boat type, and the middle part of the boat is a very long foil parallel to the middle body, so it is more like a torpedo line type. The command station enclosure is 13 meters long, 6 meters high, and the width of the tan car, which is relatively long mainly for the installation of a floating rescue cabin. At the end of the aft rudder, there are also two submerged propulsion motors and auxiliary propellers. Ashi Yu.

For a coastal country, the navy is a military force that must be properly developed. If a country does not have a strong navy, it is likely to be targeted by other countries or forces at every turn when developing its own country. So what should the Navy develop?

A lot of people think of aircraft carriers. It is true that aircraft carriers have an irreplaceable position in modern maritime operations, but there are not many countries that can study modern aircraft carriers.

Therefore, most coastal countries will choose to start with the development of submarines when developing their own maritime forces. Submarines are naturally very restrained, and no matter how powerful they are, they can't withstand a few torpedo strikes from underwater submarines. During World War II, the pretentious British Navy was caught off guard by German submarines and doubted life several times.

Depth of dive has always been a very important performance parameter for submarine production technology. Let's compare the diving depths of the nuclear submarines of China, the United States and Russia, and see how the nuclear submarines of these three countries have performed.

The United States is a well-deserved military power, holding the most powerful military in the world at its disposal. However, the United States focused the development of its navy on the development of naval combat units, and did not care too much about the development of nuclear submarines, so the performance of the United States' nuclear submarines in the depth of diving is relatively weak, and the most outstanding Virginia-class nuclear submarine has a diving depth of 600 meters, which can be regarded as an upper-middle level in the whole world.

However, the first country in the world to produce a nuclear-powered submarine is the United States, so the United States' nuclear submarine technology is actually not weak, but there is no focus on development.

Unlike the United States, Russia is focusing on the development of underwater combat units. Although there is only one old Kuznetsov aircraft carrier in the Russian sea, the United States does not dare to provoke Russia easily even though it has 11 nuclear-powered aircraft carriers, because Russia has a very excellent submarine fleet.

The Project 685 attack nuclear submarine is one of the most powerful aircraft carriers of the current Soviet era, with a depth of 1250 meters, which is excellent. Moreover, the submarine can also carry a variety of powerful torpedoes, which is a great threat to any water combat unit.

China is also one of the few countries in the world that has nuclear-powered submarines, but because China has been subjected to the technical blockade of Western countries when developing nuclear submarines, the performance of China's nuclear-powered submarines is relatively weak, and the current name of China's main nuclear submarine is called Type 095 nuclear submarine, with a diving depth of 500 meters. It is much inferior to other countries, but China has been blocking the development of nuclear submarines in recent years, and it is very likely that it will give us a big surprise in the future.

It should also be noted here that the current combat range of nuclear submarines is between 300 and 500 meters underwater. Even if it exceeds this value, it only proves that the country's nuclear submarine technology is excellent and does not have much real combat value. Therefore, China's nuclear-powered submarines are not as bad as we think, but the United States and Russia are too advanced in technology.
