My German Empire

Arctic.

A black guy is sailing in the deep sea.

It is indeed "big guy", this is the second nuclear power submarine for the German Navy just underwater to execute the trial mission. The ship is 98 meters, 10.5 meters wide, and the water is as high as 5,000 tons; it is indeed deep. It is at this time that the depth is 350 meters of the sea; and the speed reaches 28.

The deep depth is 350 meters, and the depth can reach 400 meters; this depth is that the Second World Submarine does not dare to imagine. Although the submarines in the Second World War I have made great progress than a battle, because of the technical limitations, general combat depth is only 100 meters to 150 meters, few dive to 200 meters.

Of course, this 400 meters is not the limit; the Soviet Union's Soviet Union is very obsessed with the depth of the submarine, because the Soviet Navy's surface ship is not as good as the US military, and it is not directly to counter the US fleet, so the Soviet Union is very Pay attention to the development of nuclear submarines, while nuclear submarines are mainly needed to reduce their noise, so they will not be discovered by the enemy's sanctuary, and the nuclear submarine loses, the smaller the noise it produces, so the Soviet Union A batch of submarines were built with expensive titanium alloys, and the pressure resistance of these submarines was much higher than the general submarine, so they can have deeper places.

At present, there is a deepest submarine in the world, which is created by the Soviet 685 attack nuclear submarine. The submarine has a surprising 1250 meters! In addition, there is no country's submarine under this depth.

However, the amazing depth brings better hidden performance that is not fake, but also a few side effects. For example, the price of the Soviet Union, the Soviet Union 600+ depth submarine is created by titanium alloy, so there is an equal gold saying. So the price is terrible. A submarine that can dive 1000 meters deep is absolutely much longer than 3-capable 400-meter-level submarine, but the operational efficiency may even be more than 200 meters of submarines.

Such a deep depth has lost actual combat capabilities, in addition to "in that", it is basically meaningless. This depth means that the enemy's anti-submarine weapon may fail while also means that your attack weapon is invalid - what is even for various temperature change, which may even make your observation resort to fail - to play in the deep sea plays a fleet is very stay……

When you need to attack the enemy, the submarine itself will come to the water in the water. Either your torpedo can take the big angle to climb the big angle, but how do the former plans to waste tonnage design? The latter implements difficulty than you have a large-scale submarine ...

The core of the submarine is hidden, speed, acoustic analysis. Relying on losing deeper to achieve this means of high cost performance.

In fact, the United States has also passed this bun road. When the US Navy develops sea wolf, the sub-depth of the class is 600 meters, intended to increase survivability. But such advanced submarines are naturally inconvenient, each ship is $ 3 billion. There are many people in the United States, as long as the performance is good, I also recognize it. However, actual use has found that high-and-submissive sea level is not much more helpful to anti-detection. The detected distance does not increase due to the increase in the deep capacity, and the enemy's anti-submarine weapon can hit this depth, it seems that the effect is not very big.

Soon Americans realize that it is nothing to entangle the extreme deep potential. Most of the people in the world are not large. Most of the waters of the submarine are not deep sea, and the deeper the submarine is under the depth of the submarines, the more expensive the housing material used by the submarine, this development is not worth the loss, so the US military development Some performance very balanced nuclear submarines.

Until the later Russian navy is considered this point of view, it also reduces the largest submerged deep; the limit of the north wind is 450 meters. It can be said that the submarines in the two countries are biased towards the shallow sea.

"Report, we have arrived at the extreme!" I heard the leader's report,

According to research, human beings have come to the Arctic to explore more than 2,000 years ago. The earliest record can be traced back to the Greeks. He has bravely sailed to the sea of ​​Iceland and northern Norway.

In 870, Scandinavian Ottar from Nier Claus, entered the Beiling House, sailed along the Cola Peninsula and found the white sea. This is the earliest navigation of the text record into the Arctic Ocean.

In 1893, Norway's explorer Nanssen led an expedition to arrive at 86 ° 14 'north latitude, which was the deepest in the 19th century.

On April 6, 1909, Matt Henson and Robert. The two of Pierre met the Arctic.

It reaches the poles on the ice, it is the limit of human challenge, but from no one tried to cross the sea from the sea.

Unlike the Antarctic mainland, it is covered by the ice and snow. It is a real land under the ice and snow; the Arctic is no land, the North Bo Ocean is just a ocean, and the extreme temperatures are frozen into a huge (Arctic glacial area 800 Wan square kilometers, winter is 11 million square kilometers), an average thickness of 3 meters of iceberg.

Ordinary submarines wanted to pass through this area of ​​8 million square kilometers, because conventional submarines need to come to surface ventilation.

The nuclear submarine does not need to float the water ventilation. The biggest advantage of nuclear power is to provide almost unlimited endurance, which contains energy in the atom, released through the cracking situation, which is the same as a boiler, used to heat the water, become steam, push the steam turbine You can output energy. The propeller can be driven directly through the speed reducer, the submarine is moved, and the generator can also be powered to power the entire submarine.

In this way, the nuclear submarine has almost inexhaustible power, and the oxygen that the submarine needs can be used to decompose from the sea water. It is not only oxygen through sea water, and there is hydrogen. Therefore, there is also a place specially stored in hydrogen on the submarine, and the decomposed hydrogen will be stored here, and the decomposed oxygen will pass through the ventilation system, and each cabin is reached on the submarine.

As for fresh water, although the submarine is equipped with seawater dilution equipment, the effect is not ideal, and the fresh water extracted is mainly used to take a shower or dishwash, and the drinking fresh water needs to be brought.

In this way, only sufficient food and fresh water are required when the submarine is sailed, and the air can be prepared, and the maximum satisfaction of the submarine navigation requirements. Specifically, how long is it underwater, it is entirely dependent on the self-sufficiency of the submarine.
