submarine differs from other ships in that it is potentially under the sea and will never show up when performing missions. We often see all kinds of submarines in various movies and TV dramas, and it gives people the feeling that they can dive for a long time after diving, and they can never float on the surface of the sea. According to different powers, submarines can be divided into conventional power submarines and nuclear submarines. Nuclear submarines are powered by nuclear reactors and have a very strong endurance. So far since the development of science and technology, how long can a nuclear submarine be underwater? In fact, the key factor is not battery life, but people. The biggest difference between
nuclear-powered submarine and conventionally-powered submarine is that if it uses conventional power, no matter how much energy it carries, there is a certain limit. There will always be the day when it burns out, but nuclear-powered submarines are different. In particular, some nuclear submarines use full-life reactors, which means that they are no longer restricted by fuel, and their endurance has also been greatly improved, reaching 1.5 million nautical miles. But generally speaking, the endurance of nuclear-powered aircraft carriers is about 200,000 nautical miles, and they can stay underwater for 60-90 days.
But generally speaking, what really limits the submarine's underwater time is not its endurance, but the endurance of the soldiers working on the submarine and how long the supply can last. Many large submarines have rich internal facilities, and some facilities for entertainment and leisure are also prepared for the soldiers. However, despite this, this is an isolated place after all. In addition to fellow comrades in the deep sea, I can't hear any sound. After a long time, I will inevitably feel depressed and boring. If the time is too long, people are prone to mental problems. Therefore, even if some nuclear submarines can stay underwater for a long time without restriction, the time for each mission will still not exceed 90 days, and it will be about 90 days at most. This is also to protect the physical and mental health of the soldiers.
is another issue of supply. Generally speaking, a nuclear submarine has a staffing establishment of more than 100 people. During the mission, these 100 people must ensure that they have food and drink, are physically active, and have balanced nutrition. Fruits, vegetables, and meat must be balanced. There are all kinds of seasonings. If you count as full Dangdang for 90 days, you must bring at least 25 tons of food and supplies. If the submarine is not large enough to bring so many supplies, it can only be as long as it takes food and supplies to dive. After all, you can't work with the soldiers hungry. If the supplies are exhausted, you must go up.
Because the working environment of a submarine is rather special, it is not like a warship, it has a relatively wide range of activities, the most important thing is that you can see the light and hear the sound, and it is not like a fighter plane, and generally will not perform tasks outside for a long time. On the submarine, the mission is always in the deep sea, and the conditions are very difficult. Therefore, the soldiers working on the submarine must go through a period of training before officially starting to adapt to that environment before they can officially go to sea to accept the task, otherwise it is easy to go wrong.
