Who knows how long that submarine can stay underwater, for how long?

According to well-documented reports, the longest underwater stay was the USS Poseidon, which sailed the world underwater for 83 days and nights and 10 hours in 1960, and only once did it come out of the podium and send the sick out because of a seriously ill number (the hull did not surface). In addition, a Russian nuclear submarine squadron completed an underwater circumnavigation of the world in 1966 (54 days); There are reports that a Los Angeles-class nuclear submarine of the United States sailed around the world for six months in 1980, but it is not credible. Generally, the self-sustaining force under water is 60-90 days.

60 days in France.

China's No. 403 nuclear submarine completed 90 consecutive days and nights of self-sustaining navigation training at sea in 1986, breaking the 83-day sea navigation record of the American Poseidon, however, the Poseidon is all underwater, and China's navigation has a long time on the surface of the water, China's public report is "breaking the highest record of its own submarine going to sea for a total of underwater navigation", the key is the accumulation, that is, there are several times to surface. Therefore, it is more credible that the US nuclear submarine has stayed underwater for the longest time.

The longest record is 90 days and nights.

A nuclear submarine can sail hundreds of thousands of nautical miles at the maximum speed of a single load, and if it is used at an economic speed, it will be even longer, and some nuclear submarines do not need to be refueled until they are decommissioned, so fuel is not a factor that limits the underwater navigation time of nuclear submarines.

The main factors that affect the underwater voyage time of a nuclear submarine are:

1. Food: The space in the nuclear submarine is limited, and the consumption of 100 people is large, but it is impossible to bring a lot of food.

2. Staff's stamina: assuming that food is sufficient. The endurance of the personnel is highlighted.

The US "Poseidon" nuclear submarine sailed around the world underwater for 83 days, and asked a psychiatrist to follow the crew to do a personnel endurance tracking test, and found that the physical strength and energy of the crew began to decline significantly after 40 days of continuous underwater sailing, and the limit was 80 days, which was no longer bearable, depression and anxiety were common, human operation errors had risen greatly, and homesickness ......had skyrocketed, the combat effectiveness of the troops decreased sharply. Therefore, countries limit the underwater "ultimate self-sustaining power" of nuclear submarines for 70-90 days. China's nuclear submarines once made 90 days and nights of continuous sailing, and after public reports, they shocked the world.

3. Mechanical failure: If a major mechanical failure occurs, it may also force the submarine to float or return to sea.

Air is not a factor that affects self-sustaining force, as there is an air regeneration system on the submarine. It is possible to break this record in the near future.

It is China's No. 403, and it is our pride.

Hello dear: about 13 minutes. Jujube allows the average person to dive for a maximum of about 13 minutes.

The longest time recorded for a dive was 13 minutes and seconds, and the record for the deepest distance was 162 meters. In addition, diving is intended to be an activity that goes below the surface of the water with or without professional tools for underwater survey, salvage, repair, and underwater engineering operations. Later, diving has gradually developed into a leisure sport with underwater activities as the main content, so as to achieve the purpose of physical exercise and leisure entertainment, and is widely loved by the public.

Third, the design of the two is different:

1. The design of the Nautilus: The Nautilus's hull is made of steel plates, and the ratio of the density of steel to the density of seawater is ten to seven to eight. The first hull was at least five centimeters thick and weighed 394.96 tons.

The second inner shell, the keel, was fifty centimeters high and twenty-five centimeters wide, and weighed only sixty-two tons. The weight of the machinery, the ship engine, the various ancillary implements and fixtures, the various wall panels and timber inside, and the three hundred and ninety-four .96 tons on them, together with the three hundred and ninety-six tons, are a total weight of 1,492.13 tons.

2. Design of submarines: R&D requires a high degree of and comprehensive industrial capacity, and only a few countries are currently able to design and produce them on their own. In particular, ballistic missile nuclear submarines are a key pole of the nuclear triad.

Submarines were also early stealth vehicles. The noise of a submarine can be "drowned" in the vast ocean background noise when it is reduced to about 90 decibels, which is not detectable by modern sonar.

<> "How Long Can a Submarine Crew Stay Underwater?"

Conventional submarines have a limited amount of time to lurk underwater, and generally need to surface at night to start the diesel engine to recharge the battery. There is no need to consider the question of how long a submarine crew can stay underwater. When the nuclear submarine appeared, the submarine had almost unlimited submarine capability.

Theoretically, you can stay as long as you want below sea level. Then the maximum diving time of the nuclear submarine under water depends on the psychological and physiological endurance of the submarine crew. How long can a nuclear submarine stay underwater?

The record for the longest ultimate voyage time of a US nuclear submarine is 84 days, and China's nuclear submarine once set a record of 90 days of extreme sailing under water.

All of these records were deliberately created under extreme test conditions. Nuclear submarines will not be able to dive for such a long time in actual combat and patrol. In such a confined environment underwater, staying in the artificially created living environment for a long time will cause damage to the physical and mental health of the crew, and directly affect the combat capability of the submarine.

The underwater diving time of the nuclear submarine Hebi Brigade Boat is generally not more than 14 days. Float on the surface of the water to allow each crew member to take turns out of the cabin to get some fresh air, as long as it is as safe as possible. It's a bit like letting off in prison.

With the advancement of technology, some conventional submarines have been able to achieve a maximum underwater diving capacity of nearly 14 days due to the adoption of new technologies such as air-free AIP power units and replacing lead-acid batteries with lithium-ion batteries. It seems that it is reasonable for modern conventional submarines to design their maximum underwater submersible capacity for 14 days as the goal. This takes into account not only the bearing capacity of technical equipment such as batteries and Stirling engines, but also the psychological and physical bearing capacity of the combat personnel on the submarine.

The underwater endurance of the nuclear-powered submarine is 200,000 nautical miles, and the self-sustaining power is 60-90 days.

A nuclear submarine is a type of submarine that refers to a submarine designed with a nuclear reactor as the power source. 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**. 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 to be dismantled was the USS Nautilus, which began its first sea trials on January 24, 1954, announcing the birth of a nuclear-powered submarine.

At present, there are six countries in the world that openly claim to have nuclear submarines, namely: the United States, Russia, the United Kingdom, France, China, and India (India's nuclear submarine USS 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.

Alas, the question you ask should be": The duration of the submarine's underwater stay".This refers to the maximum time that the submarine can continue to stay in the cabin isolated from the atmosphere after it enters the water, which is one of the important tactical performance of the submarine and directly affects the concealment and combat capability of the submarine.

The length of the underwater bean retention time of the submarine mainly depends on the on-board air regeneration equipment and its regeneration method. There are two commonly used air regeneration methods for submarines: one is the electrolysis method, which can continuously supply oxygen, but consumes a lot of electricity, and nuclear submarines generally use this method.

The other is the oxygen regeneration method, which uses the main ingredient of peroxide regeneration medicine board or oxygen candle to absorb carbon dioxide in the air and produce oxygen, which is mostly used by conventional power submarines. According to the oxygen production method, the underwater stay of a nuclear submarine can be indefinitely long, but taking into account the actual endurance of the crew to work and live underwater, it usually does not exceed three months. The amount of air regeneration equipment carried by conventional submarines can ensure that the submarine stays underwater for about 600 hours.

Conventional powered submarines stay underwater for 600h
