What is the maximum limit of the dive of a Chinese submarine?

The deepest dive is the scientific research submarine, which has exceeded 8,000 meters 2-3 years ago.

This depth can already reach 99% of the world's ocean floor.

In fact, you can dive to a depth of 3,000 meters to reach 90% of the world's seabed.

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.

In fact, no matter how deep it is, it doesn't make much sense. 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 made it impossible for the vast majority of sonars in service to detect the submarine.

Nuclear submarines dive at a higher depth than conventional submarines.

The deepest submarine in our country is the 094 Advance Ballistic Missile Nuclear Submarine. The maximum depth of the dive is 400 meters.

The depth of the submarine is one of the top secrets of the Navy, and the public data can only be used for reference. Generally, the diving depth of nuclear submarines in various countries is 300 to 600 meters, which is mainly selected according to the task, and there is no point in increasing the diving depth by one, it will only increase the cost of construction.

The deepest combat submarine in the world was the Soviet Union's M-class attack nuclear submarine "Komsomol", which recorded a dive of 1,027 meters. As for the other submarines, they are all around 300 meters, and 400 meters is already very good. (Personal opinion, for reference only).

This is a high-level military secret, and I can only speculate, I estimate it at around 800 meters.

The maximum depth of the submarine is 1250 meters.

As of 2021, the maximum depth of submarine diving is 1250 meters (data statistics 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 drop-shaped line, with a spherical head and a drop-shaped pointed tail, but it is slightly different from the drop-type boat, and the middle of the boat is a very long parallel body, so it is more like a torpedo line. The command station enclosure is 13 meters long, 6 meters high and wide, and its relatively long length is mainly intended for the installation of a floating rescue capsule. At the end of the aft rudder, there are also two submerged propulsion motors and auxiliary propellers.

Boat-type structure

The basic structure of the Type 685 still adopts the traditional double-hull structure of the Soviet Union, with a diameter of about 9 meters and a 48-t titanium alloy. To this end, the Severodvinsk shipyard has carried out a lot of research and experimental work to solve the problems of titanium alloy processing technology, the manufacture of pressure-resistant hulls and the strength of pressure-resistant hulls, and it is also the third type of Soviet and Russian nuclear submarine made of titanium alloys.

The use of titanium alloy to make submarines can not only effectively increase the depth of submarines, but also reduce the possibility of anti-submarine aircraft using magnetic detectors to detect submarines. Because titanium alloy not only has high strength and light weight, but also has the advantages of low magnetic properties, this is the main reason why the Russian Navy attaches importance to increasing the depth of diving and uses titanium alloy to manufacture submarines.

Summary. According to reports, the Chinese submarine went to a depth of more than 10,000 meters under the seabed, which is one of the deepest in the world.

According to reports, the Chinese submarine went to a depth of more than 10,000 meters under the seabed, which is one of the deepest in the world.

China's Type 091 attack nuclear submarine: the ultimate depth of diving is 300 meters; Chinese Type 092 ballistic missile nuclear submarine: about 300 meters deep; Chinese Type 093 attack nuclear submarines; Dive to a depth of 300 meters; Chinese Type 094 strategic nuclear submarines:

Sneak depth greater than 300 meters; China's Type 095 attack nuclear submarine: foreign media speculate that the maximum depth is 600 meters; China's Type 096 strategic missile nuclear submarine: It is estimated that the depth of the submarine can reach 600 meters.

At present, according to foreign media reports, China has successfully conquered the "super steel" technology, and Ma Weiming, an academician of the Chinese Academy of Sciences, has developed a shaftless all-electric propulsion technology, if it is used on nuclear submarines, it can make the 096 submarine dive to 900 meters, and it is quieter, it can be said that the development of China's submarines is exciting.

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.

Summary. The maximum depth of military submarines is 1250 meters.

The maximum depth of military submarines is 1250 meters.

As of now, the deepest record of a military submarine is the first to create the Soviet 685 attack nuclear submarine "Komsomol Member", on August 5, 1983, this Soviet submarine set a military submarine diving limit of 1,250 meters.

As of 2023, it can dive to about 1300 meters.

Russia, the world's first nuclear submarine power. Based on the foundation laid by the Soviet Union, Russia's nuclear submarines are very powerful in terms of pressure resistance, so their nuclear submarines generally dive deep.

Russia has a nuclear submarine made of titanium alloy all over the body, called the Komsomolskaya nuclear submarine, which is currently the deepest submarine in the world, capable of diving to a depth of 1,300 meters.

The U.S. Navy is the most powerful navy in the world, so whether it is a nuclear submarine or an aircraft carrier, as long as it is built by the United States, it will not be too bad. The creator of the U.S. diving depth record is the Seawolf-class nuclear submarine, which is a high-tech submarine that brings together various black technologies in the United States.

It is the world's quietest submarine, and it can be said to be a veritable deep-sea ghost. Its depth is also second only to Russia's Komsomol nuclear submarine, reaching 800 meters.

The increased depth of the nuclear submarine has the following effects:

First, it can reduce the possibility of being detected by the magnetic detector on the anti-submarine aircraft, and titanium alloy has the advantage of low magnetism, which is a suitable material for building submarines.

Third, it can delay the appearance of propeller cavitation slag tremor, thereby reducing propeller noise.

Fourth, if it is defeated by the enemy's depth charges, it has a longer maneuver time, which reduces the possibility of the submarine being hit by depth charges; Fifth, it is possible to expand the range of submarines sitting on the bottom of the sea, as well as the possibility of passing through the anti-submarine zone.
