Nuclear-powered aircraft carriers need to be installed in Shanghai to provide power when the nuclear reactor is not working. Similarly, the same is true for nuclear submarines. In addition to nuclear power, there are also auxiliary diesel engines and battery packs.

Take the famous Akura-class nuclear submarine of the Russians for example. It not only has nuclear reactors, but also two sets of lead-acid batteries and two DG-300 diesel generators. Of course, these systems are all backed up, so they don’t last long, and generally they can only last for more than ten days of navigation.

In the period when there is no electric propulsion, that is, when the steam turbine directly drives the propeller, the submarine will install a low-speed propulsion motor on the spindle. In this way, if the nuclear power fails, the submarine can also be promoted. Now the entire boat uses comprehensive power, whether it is diesel engine or nuclear power, it is all used to generate electricity, which makes it easier to combine.

Since there are these auxiliary powers, there must be a chimney.

Yes, there are indeed chimneys on nuclear submarines, but this chimney is completely different from the chimneys of conventional surface ships. It is a closed flue and is generally set at the back of the command tower enclosure at the highest position.

In this way, when sailing, a black smoke will be dragged at the tail, just like a fire inside a submarine.

There was such a scene in the trial of the British agility level, which was shocking.

Since the chimney is on the command tower, the diesel engine of a nuclear submarine means that it can only be used in the water surface. This is understandable. After all, it is necessary to use a diesel engine, which must be a malfunction and there is no way to submarine. The use of a diesel engine is to prevent the submarine from losing power and can drive it back.

Now, everyone was moved as they watched the submarine start the diesel engine and gradually leave everyone's sight.

"The power of the auxiliary machine system is not low."

"Our military industry has developed so fast over the years, and these power machinery can be produced domestically."

Back then, when manufacturing advanced diesel-electric submarines, they used the diesel engine of MTU. This diesel engine was used on many submarines around the world and is the most representative one.

Therefore, when the East exported submarines, it was threatened by the Germans' supply cutoff. After all, the Germans were also exporting diesel-electric submarines, which led to a conflict of interest between the two sides. However, Mingzhou Group was prepared and immediately took out its own submarine-specific diesel engine: the TBD-620 diesel engine of Mannheim technology.

This type of diesel engine has different structures, L-shaped and V-shaped, and has different cylinder numbers. The 16-cylinder product has a power of more than 2,000 kW, making it the best choice for diesel-electric submarines. At the same time, one can also be used on a nuclear submarine to provide auxiliary power to the nuclear submarine.

"A new era for our navy has arrived." Seeing the submarine leave, Wu Shengli continued to murmur.

The straight-line distance between Zhoushan and Mingzhou is only 67 kilometers. Even if it is a detour on the sea, it is within 100 kilometers. For submarines, a night of navigation is more than enough. Before dawn the next day, the submarine had already started to the cave reservoir of Zhoushan submarine base.

Speaking of domestic nuclear submarine bases, there is one in the north and the south, and the one in Yalong Bay in Qiongzhou will be built into the largest one. However, it is not realistic to drive a submarine that does not have the ability to submarine to go directly to Yalong Bay, so it is more convenient to be in Zhoushan.

Like other bases, there are not only submarine wharfs exposed outside, but also special cave warehouses. Mooring experiments are performed in the cave warehouse, so no one knows.

That morning, after breakfast from the Mingzhou Shipyard, a group of people arrived at the Zhoushan base.

From a distance, you can see several submarines docked on the submarine dock on the helicopter, three of which were wearing hats on the command towers, which looked particularly different.

"At present, our navy has equipped six 039 submarines and is very satisfied with the performance of this submarine." Wu Shengli said: "Compared with the old Kiro-class submarines, the quietness is better, the internal facilities are more complete, and there is also an AIP system that can sail underwater for a long time and can even fight against nuclear submarines."

After all, nuclear submarines are too expensive, and only the United States is rich and willing to eliminate conventional submarines and operate all nuclear submarines.

However, they also felt some of the defects of nuclear submarines, such as the large displacement of nuclear submarines and inconvenient activity in shallow sea areas. The sensitivity of nuclear submarines is too high and there is almost no possibility of export. Otherwise, how could the international submarine market allow German submarines to dominate?

The navy's nuclear submarines are all treasures and are expensive to build. The main mission is to accompany the aircraft carrier to sea. Conventional submarines can patrol everywhere within the territorial waters of the motherland to supervise possible enemies underwater.

Looking at the conventional submarines, Qin Tao nodded silently: "It is the mission of our Mingzhou Group to provide the Navy with the most advanced equipment. We will continue to upgrade submarine technology and make our conventional submarine performance more advanced."

There is no doubt that the conventional submarines in the East are advanced in technology. When the Pyramid Navy and the US Navy were confronting each other, they once sneaked to the side of the US aircraft carrier, which surprised them.

However, the technology upgrade is endless, and the Navy's submarine performance still has room for improvement, stronger Sterling engines, more advanced electronic equipment, some vertical launch cabins, etc.

"In the past, we planned to use this place as an aircraft carrier base." Wu Shengli said: "At that time, we chose two places as aircraft carrier docks."

"before?"

"Yes, that should be 70 years."

The Navy had long had the idea of ​​an aircraft carrier and had an aircraft carrier plan in 70 years. Unfortunately, the country's industry was not strong at that time and could not create that powerful combat machine at all.

But it was studied in depth at that time, and even the aircraft carrier dock was ready.

"At that time, we chose two locations, one of which was in Baitangao, the southern end of Jintang Island, as the docking base, and established a supply and support base for aircraft carriers on the opposite side."

This chapter is not over, please click on the next page to continue reading! Wu Shengli is very familiar with this place, and is obviously also a former witness, so he introduced it to him.

The water surface of this first location is wide and has enough water depth, and can also avoid all kinds of wind and waves. It is a rare shelter. If you want to use it as an aircraft carrier base, you can also use the train.

However, the traffic was still poor at that time, and there were many small boats here, which was not conducive to confidentiality.

"The other location is between Guoju Commune and Xiangyang Commune. This location is also good. Behind the mountains, the hillside is close to the seaside. As long as the stones on the mountains are dug out, you can build a pier. There is a waterway to the south. As long as you leave the shore, the water depth is more than twenty meters."

"It's a pity that the navy did not take action." Qin Tao took a look at the surrounding terrain again, and the helicopter had already begun to land.

"Now, these places have been built with residential buildings. It is impossible for you to continue using the harbor here as an aircraft carrier base."

"Yes, over the years, real estate has developed rapidly, and we didn't expect these places to be attracted by developers and build sea view houses." Wu Shengli said: "But now, the navy's strategy has also been clear that we don't need to deploy aircraft carriers here."

Once upon a time, the fleet here was the strongest among the three major fleets. After all, they had to face too many threats. They obtained a lot of advanced equipment from the Navy, such as the modern class, the glorious class, and the Kilo class submarine. Almost all the equipment they bought from outside were given to them.

For a period of time, the strength here was the strongest, but as the shield ships continued to ground, they were rarely assigned to them, and their strength was constantly declining, and the most important thing was that they did not have an aircraft carrier!

Without an aircraft carrier, you can only use shore-based aviation. Naturally, the flexibility cannot be compared with that of an aircraft carrier. However, when needed, both the north and the south can be driven over. Moreover, more importantly, they will have the opportunity to directly use the airport of Baodao in the future. At that time, their shore-based aviation will be able to penetrate the Pacific Ocean, so there is no need to use an aircraft carrier.

The helicopter landed at the base, and a group of people got off the plane. Many people in the base were already waiting for everyone, one of the old men was particularly eye-catching.

When Wu Shengli saw him, he immediately went up and shook hands warmly.

"Lao Zhang, why are you here?"

"This is my home. After retirement, I lived here. The troops gave me a lot of convenience and allowed me to enter and exit the base at any time. I would walk around and take a look when I had nothing to do. I was happy to see the development and growth of our navy."

Lao Zhang?

Which Lao Zhang?

The old film "Sea Eagle" of the Bayi Factory emerged in Qin Tao's mind.

"This is Mr. Qin, right? You are a hero of the development and growth of our navy. I have wanted to see you for a long time, but you are too busy and I feel embarrassed to disturb you."

Seeing Mr. Zhang talking to him, Qin Tao quickly went up and shook hands: "May I ask, did you lead the 102 boat twice in a day in 55 and use a single boat to sink the enemy gunboats with torpedo tactics?"

Mr. Zhang smiled and his skin had more folds.

"I really didn't expect that there are still people who can remember my results now."

"Heroes will never be forgotten." Qin Tao said: "You are old seniors like you who are worthy of learning and admiration!"

Qin Tao was just talking about Mr. Zhang’s first victory. In fact, Mr. Zhang participated in six naval battles in his life, sinking three enemy ships, and severely damaged one. He made outstanding contributions! Now facing such an old hero, Qin Tao certainly admires him very much.

Seeing the admiration in Qin Tao's eyes, Mr. Zhang's smile became even brighter.

"By the way, our Mingzhou Group is also open to you. You are in Zhoushan and are very close to Mingzhou. As long as you are willing, you are welcome to visit our factory at any time!"

Such old heroes have no other hobbies, they just like to look at naval equipment. Mingzhou Group is the most advanced naval equipment manufacturer. They have many good things there, which are all loved by old heroes.

The old hero is holding it in Zhoushan every day, knowing that there are good things around him, but he can't see it. He is unbearable to think about it.

"Is that so? Then I'm really rude!"

"Of course, you can also live in our Mingzhou. Our guesthouse specially prepares a room for you. You will not charge any fees for you. You will be free of food and accommodation."

After Qin Tao finished speaking, he added: "Of course, what equipment do you need to look at, the Navy must agree in advance."

"The Navy has no objection." Wu Shengli spoke immediately.

Navy veterans and combat heroes want to see advanced equipment, what else can they do? Such an old man will definitely not be a spy.

"I'd better stay in the base first and see our nuclear submarines. We have never had a nuclear submarine in our conventional submarine base. This is the first time a girl gets into the sedan." Mr. Zhang said: "You are also here to see the nuclear submarines, let's go together."

The other leaders in the base came up to greet Wu Shengli and others, and then went to the submarine cave depot together.

There are submarines outside, which are for others to see. The submarines hidden in the cave warehouse are secret people, making the other party not know how many submarines they have and when they will take action.

There is waterway inside the submarine cave repository, and you can enter and exit while you enter, so that the submarine does not need to turn around inside the cave repository. Many submarine bases are designed in this way.

At this time, in the submarine cave warehouse, a huge submarine was docked on the berth, and a lot of equipment had been added next to it, which were used for mooring experiments.

"At the time, our superiors attached great importance to our Zhoushan base and all kinds of equipment were delegated to our command. Later, we planned to hand over the submarine directly to our base, but we rejected it." Zhang Lao said: "At that time, we believed that the submarine detachment was a strategic force, and the submarines needed to be controlled by the superiors or even the highest leaders, so our base could not command it."

In that era, ordinary diesel-electric submarines were considered strategic forces and could complete many strategic tasks by relying on concealment. You can tell by looking at the food that the standard of one or two cents for each meal for ordinary soldiers, while the submarine soldiers were one piece of seven, and each meal was big fish and meat.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! But now, conventional submarines are of course not considered strategic troops, and strategic troops must be nuclear submarines.

"Mr. Zhang, your awareness is so high." Qin Tao sighed.

"We are the People's Navy, and ships and sailors are not our personal ones. Our mission is to do our duty, lead them well, manage them well, and make them an excellent People's Army." Zhang Lao continued: "When there is an enemy invasion, we must lead them to win battles, and we cannot treat them as decorations or vases."

After listening to these words, Qin Tao was deeply moved. This is the enlightenment of the older generation of soldiers! Everything is for the motherland and the people, and his father is also like this.

"Report, the mooring experiment is ready, request begin!"

"Can you start!"

"yes!"

Kwasha and others have already boarded the submarine.

For submarines, mooring experiments are also very important. They are mainly to check the integrity and reliability of the submarine, whether various equipment inside the submarine can work normally, whether the noise and vibration are within the designed range, etc. For nuclear submarines, nuclear reactors must be started and various tests must be carried out. Depending on the progress, it may take several months to six months.

Only by passing the test on the shore first can you test it at sea. After all, a big guy like a submarine is very dangerous. If you are not careful, it may be a tragedy that will kill all the crew members. You must not be neglected.

As an excellent submarine designer, Kwasha is also very proficient in mooring experiments. Now, he has to be present in person to ensure the normal progress of mooring experiments.

For others, they can walk around the submarine during the experiment. Everyone took a quick look and were very satisfied with the submarine.

It was already noon after coming out, and everyone was reluctant to leave and finally took a look at the submarine.

"Dad, when will the 096 submarine be tendered?" Qin Tao asked.

Wu Shengli asked back: "What do you think?"

There is definitely more than one submarine in 095, but it will not take the second one until the sea trial is over. For those who engage in submarines, this is no longer a problem. What they want to tinker with is a bigger guy.
