Chapter 2324: Type 971 nuclear submarine

Following President Qin, it was an honor. Now, President Qin is finally here. Everyone is expecting in their hearts that the Navy's nuclear submarine force will have a leap in development.
Qin Guan didn't even know that when he followed Captain Xu to the nuclear submarine construction base, a large number of naval officers also arrived, and the entire inspection team was vast.
The construction of nuclear submarines takes a long time. For example, the last 091 class, from construction to service, took 13 years.
The construction of nuclear submarines is specialized.
On land, there are assembly workshops for nuclear reactors and supporting departments for various systems. Of course, there are also various hydraulic machines required for normal hull construction, and there are also huge slipways for assembling welded hulls.
Now, the slipway is empty, and you can even see a few welded cabins next to the slipway, and those cabins have been abandoned, so now they are stacked here, and it seems that they might even There is a sense of desolation.
"After repeated research, we decided to abandon the construction of the last Class 091 submarine." The commander of the navy who came to Qin Guan accompanied Qin Guan and introduced to Qin Guan: "Class 091 submarine is out of date and cannot afford it. The future mission comes, and at the same time, our navy needs to invest a lot of money in aviation, so it temporarily abandoned the construction of the last ship."
The Navy’s aviation has developed rapidly, and surface ships have also developed rapidly. Therefore, it is obviously wasteful to build outdated nuclear submarines that cost a lot of money. Therefore, the construction of nuclear submarines was terminated.
Now, after hearing the words of the commander of the navy, Qin nodded his head: "Yes, it is not wrong to maintain our large-power navy and focus on the construction of surface ships. I personally still have the development of our new generation of nuclear submarines. Some opinions."
Qin Guan’s eyes looked at Huang Lao in front of him, the old Huang Lao, who was once the designer of the 091 nuclear submarine. Back then, they developed the first-generation nuclear submarine in Han, and their information was scarce. To what extent, someone brought back a model of a nuclear submarine from abroad, and they all brought it and studied it carefully, like a treasure. With their insistence, the first-generation nuclear submarine was finally produced.
But now, they are all old. Behind them, there is the second-generation R&D team of Han. Now, Qin Guan is introducing them.
"The submarine must be fully adapted to underwater navigation, and it must have a beautiful and smooth appearance, Xiang Jing, unfold my drawing for everyone." Qin Guan said.
The Xiucai had left, and Qin Guan was still a little uncomfortable. Now, Qin Guan asked Xiang Jing to unfold the largest sheet of the materials he had brought. It was about three meters long. After unfolding, it looked like a scroll.
Han's submarine, even if it has developed to 093, there is one thing that is criticized, that is, the appearance is not smooth! Especially the connection between the command tower and the hull is too rigid, it looks like the command tower is directly inserted into the hull. This design is too primitive.
Speaking of the design of nuclear submarines, Qin Guan appreciates Xiong Guo's design more. Among their nuclear submarines, Type 705 and Type 971 are very beautiful in appearance. The control tower is perfectly integrated with the hull, just like Underwater sharks are like sharks, and the proportions of the various parts are so coordinated. The command tower is like a shark's dorsal fin, which grows larger from top to bottom, and the back part has a backwards. The entire command tower is not particularly high.
As for how the domestic submarine designers will design in the future, that is their business. What Qin Guan has now brought out is the 971 design drawing, because the nuclear submarine that Qin Guan plans to exchange is the 971.
Xiong Guo's nuclear submarines have developed a variety of models, which makes Qin Guan feel that it is difficult to choose. Which model should I exchange from the weapons graveyard?
Speaking of Xiong's advanced submarine, we must first mention the 705-class nuclear submarine. This nuclear submarine is Xiong's second-generation attack nuclear submarine. It not only uses expensive titanium alloys to build the shell, but also makes it extremely high. The submarine depth is a nuclear reactor with metallic sodium coolant that has been used across the ages, greatly increasing the power of the nuclear reactor, reaching a high underwater speed of 41 knots, and it is definitely a super submarine.
Unfortunately, the performance of this submarine is too unstable, especially the nuclear reactor, which might cause an accident, so Qin Guan can't get this submarine over.
After this, there are Type 685, Type 945 and Type 971, almost all advanced submarines representing the level of Xiong Country in the 1980s.
Among the three types of submarines, the Type 685 is experimental. Only one was built, and it sank in 1989. Therefore, Qin Guan would definitely not go to the seabed to exchange this submarine. The remaining Type 945 , Almost all of them are in service. So, what Qin Guan can exchange is only Type 971. After all, the number of such submarines is huge, and there are a large number of them in the cemetery of Xiong Country’s nuclear submarines. If Qin Guan needed it, he could even exchange four or five ships at once.
The Type 971 attack nuclear submarine was built by the Xiong State Navy after the Type 949 cruise missile nuclear submarine. It is the last conventional attack nuclear submarine developed before the disintegration of the Xiong State, and it is also the most built attack nuclear submarine. One of the main reasons why it can be built in large quantities is that only the inner shell is made of titanium alloy, and the outer shell is made of conventional high-strength steel. Therefore, its construction cost is much cheaper than that of submarines made of all titanium alloys. equipment.
Moreover, the predecessor of the Type 971 nuclear submarine is the Type 671, which is the famous Victor type, and the backbone of the Xiong State Navy's submarine force. Therefore, the advanced nature and practicality of the Type 971 are beyond doubt.
If you want to talk about more advanced, there are of course, such as the Virginia level of the Eagle Nation, the 885 level of the Bear Nation, etc. However, these are the technologies of later generations. After all, it is only the late 1980s. Many technologies are now a bit too advanced. For example, Seawolf and Virginia, only the outer sound-absorbing tiles are cast integrally with polyurethane as the base material. The process inside is very difficult to achieve.
Therefore, Qin Guan took out the drawing of this submarine and explained it to everyone.
"First of all, when looking at a submarine, we must first look at its aspect ratio. These, Huang Lao studied the submarine model back then, also to study these basic data. We now know the best submarine underwater data. The aspect ratio is seven to one, but this will bring about other problems, so when we design, we will adopt a slightly elongated drop shape. Now, this submarine is also like this."
