Great warships

Kvasa thought of the red empire of the past. Only that red empire could build such a powerful submarine. No, the red empire couldn't build it either. After all, the red empire didn't have such a large-diameter bending machine!

Kwasha is grateful to be able to come to the East. Only in the East can he see the miracles one after another!

Not to mention the aircraft carriers outside, they are not in charge of them after all. In terms of submarines, Dongfang has reached a world-class level!

"Kvasa, please introduce it to the leaders." Qin Tao walked to his side with a smile: "What kind of advanced technology is used on this submarine."

"Okay, let's start from the beginning. The sonar on the bow is currently the largest submarine sonar in our country. It mainly uses passive methods and can detect Los Angeles-class submarines a hundred kilometers away." Kvasa knew these indicators well. Immediately he started to introduce it nonstop.

I think back then, the Los Angeles-class submarines were what the East looked up to, but now, the East can finally easily leave the Los Angeles-class submarines behind. Even the most advanced submarines in the West cannot compete with the East's submarines!

"A side sonar array is used on the side of the hull. Since the hull is longer, it can accommodate more arrays. The Los Angeles-class submarine can be found at a distance of two hundred kilometers and can be accurately positioned at a distance of one hundred kilometers. , can launch anti-submarine torpedoes to kill opponents at any time.”

"Can you kill your opponent a hundred kilometers away?" Qin Tao was a little surprised by this. He had never heard of it. The most advanced torpedo in China at present is probably the Yu-10. This torpedo uses HAP three-component propulsion Using agent and long-range fiber optic guidance technology, the maximum range can reach kilometers, which is already incredible. A torpedo with a range of hundreds of kilometers? It seems that I have never heard of it.

Wu Shengli smiled. His son-in-law was a shipbuilder, and he had never been exposed to other subsystems. Moreover, he usually sat in the office and was aloof. He had not looked at many design drawings carefully, so he definitely didn't know.

"We have developed many advanced torpedoes in China. After the Yu-10, there is the Yu-11. This torpedo is an electric torpedo that uses the lithium-ion battery pack with the highest energy density, which is what we use in our Pacific Electric Vehicles. That kind can be equipped with different battery packs according to different targets. If four batteries are used, it can have a range of more than one hundred kilometers."

Torpedoes mainly have two kinds of power: heat engine and battery. The power of the heat engine is relatively direct, but bubbles will be generated during navigation, which is not conducive to concealment. The battery power is very concealable, but the energy density is limited.

The initial torpedoes used lead-acid batteries, which were good if they could travel twenty kilometers. Later torpedoes began to use silver-zinc batteries, with a range of thirty or forty kilometers. If you want to continue to increase the range, you must use more advanced batteries.

What's more advanced? Of course it’s a lithium-ion battery!

The energy density of silver-zinc batteries is about 100 to 150Wh/kg, which is similar to the first generation lithium batteries. However, with the rise of electric vehicles, the energy density of lithium batteries has also been continuously improved, and has now reached 200Wh/kg. Last year, Pacific Electric Vehicles launched a new 4680 battery with a single energy density of 300Wh/kg, which means that the torpedo’s range can be doubled by just changing the battery.

But... Qin Tao frowned: "Is safety guaranteed?"

"Of course there is no problem with safety, and we don't need it to be charged and discharged repeatedly," Kvasa said.

The main problem with lithium batteries lies in charging and discharging. Overcharging or discharging will cause problems. When used on submarines, they are disposable. Under the management of advanced battery control systems, the occurrence of accidents can be greatly reduced.

Qin Tao still frowned: "Don't be afraid of ten thousand, just be afraid of the unexpected. I don't recommend our expensive nuclear submarines to use this kind of torpedo. It is better to use silver-zinc batteries honestly."

When Qin Tao deceived the people on the island, he introduced how useful lithium batteries were and asked their submarines to replace lead-acid batteries with lithium batteries. If they exploded and caught fire underwater, that would be fine. However, his own nuclear submarine would be terrible. Be careful. The tragedy of Lao Maozi's Kursk was right in front of him. He used an easily explosive torpedo and ended up destroying himself.

Silver-zinc batteries are early rechargeable batteries with slow charging speed and low capacity, but they are safe.

"Actually, the development of nuclear-powered torpedoes is the direction." Kvasa said: "Nuclear-powered torpedoes have a strong endurance. Needless to say, one hundred kilometers or ten thousand kilometers is no problem. They can also be concealed. If they are equipped with nuclear warheads... the enemy The fleet was destroyed and you wouldn’t know who did it.”

Lao Maozi has a similar nuclear torpedo, called Poseidon. It uses a liquid metal nuclear reactor and can sail at a depth of one thousand meters. The enemy is not aware of it at all. Lao Maozi considers it a big killer.

However, this thing has not been tested in actual combat, and no one knows its specific performance. Everyone has heard of a lot of accidents involving liquid metal nuclear reactors.

"Okay, let's not talk about this anymore. We are here to see the submarine today, not the torpedoes." Wu Shengli said, looking at the submarine: "Can we go inside and have a look?"

The submarine has been built and is waiting to be launched. However, in order to keep it confidential, the submarine launch will be done at night. There is still a while, so why not go inside the submarine and have a look!

"Of course you can, but because the interior of the submarine is too complicated, you must follow closely and don't look around, otherwise you may be left behind."

"Come on, let's get off the stage."

The submarine's conning tower is too high to get in from there. You can just get in through the hatch in the front of the submarine. There is a platform next to it and you can just climb up.

However, before entering, the logistics staff waiting aside gave each leader a small device with only a small screen and no other information.

"what is this?"

"Radiation meter." Qin Tao introduced: "Although the nuclear reactor will not be started until the nuclear submarine is launched for mooring testing, the nuclear fuel has already been stuffed in, so there may be accidents."

The nuclear fuel of a nuclear submarine is added during construction. If the nuclear reactor and the nuclear submarine do not have the same life span, complex fuel replacement operations will be involved in the process, and it will often need to be overhauled in one or two years.

"Of course, if some leaders are unwell, they should not go in."

Qin Tao's words had the opposite effect. Who can give in at this time? You have to go in and take a look, and this may be your only chance.

So, a group of leaders wore radiation meters, walked up to the stage with their heads held high, and then got into the submarine.

"Leaders, follow me. Let's go forward first. In front is the torpedo room."

The diameter of the pressure-resistant shell is 13.4 meters, and the advantage is that the interior is very spacious! Especially when they came to the torpedo room, everyone was stunned by the spacious space inside.

The width of an ordinary three-bedroom house with one living room in the east-west direction is only 11 to 12 meters, and the width is 13 to 4 meters, which is almost as big as a flat floor!

"It's no problem to have a meeting here. Hey, why are there more beds here?" Immediately, the leader discovered something: in this wide torpedo cabin, there were actually three rows of beds, just like the earliest Datong bunks. The row can sleep about ten people, and each person can be assigned a bed more than one meter wide!

The torpedo room of the submarine is far away from the power cabin and is very quiet, so it is a place that many sailors like to come. In the past, domestic submarines had small space. After going to sea, many sailors hung hammocks in the torpedo room to sleep. But later, as submarines With the increase in intelligence, fewer and fewer sailors are needed, and the space of submarines is getting larger and larger. Everyone has a place to sleep, and there is no need to hang a hammock here.

Why is it now being used as a temporary sleeping place?

"Leader Wu, after the submarine is launched, it will conduct a mooring experiment. After the mooring experiment is completed, it will go to sea. Our technicians will go to sea with the sailors, so the original beds will not be enough, so we set up a folding bed here in advance. "These folding beds are internal equipment of the submarine and can be put away when not in use. If other personnel are carried on the submarine in the future, they can also have a place to sleep," Kvasa said.

One of the beds belongs to Kvasa, and Kvasa will also participate in the sea trials of this submarine! All the leaders stood in the torpedo room, and they still felt that it was relatively spacious inside. It was like having a meeting in a large conference room. Everyone looked at the various fixing racks and imagined what it would be like if it was filled with torpedoes in the future. Looks like.

Since the bow sonar occupies all the space, the torpedo launch tube is designed to the side and is also tilted inside. The big guy looked at the launch tube, studied it some more, and then walked back.

"This is the weapons launch console." Kvasa continued to introduce.

All are vertical cabinets, and the most surprising thing is that these cabinets are actually installed on rubber shock-absorbing supports. I originally thought that it would be enough to install engines and the like on shock-absorbing devices, but I didn't expect that these cabinets also have Shock absorbing device.

Everyone was surprised.

"Going through here, we walked downstairs. Below is the living area. There are sailors' dormitories and a restaurant. In addition to providing food and drink for the sailors, the restaurant can also be used as a place for leisure and entertainment in their free time. You can play chess in it. , reading, and studying. We installed a TV inside, so everyone can watch the programs they want."

After going down, everyone was shocked. This restaurant is really big!

The advantage of increased drainage is that it makes life and entertainment easier, and proper relaxation helps to work better.

Since submarines work in three shifts, the submarine's restaurant only needs to be able to meet the dining needs of one-third of the people, and the restaurant in front of you is enough to satisfy hundreds of people on the submarine dining at the same time!

How many people are there in total on a nuclear submarine? There are only about a hundred people!

Lao Maozi's Typhoon-class nuclear submarine is the largest nuclear submarine in the world and also has the largest number of people, with a staff of 175. The Yankee's Ohio-class nuclear submarine has a staff of about 150. These are submarines from the Cold War era. Now, with the automation With the use of equipment, the number of people required on nuclear submarines is also decreasing. Lao Maozi's Beifengshen nuclear submarine only requires 107 people, one less than Liangshan's 108 generals.

096, a monster with a displacement of tons, only needs about a hundred people. Therefore, this restaurant means that it can hold meetings for all crew members. Of course, this is only in a moored state. If When going to sea, there are always some people who need to stay at their posts, so the restaurant here is definitely sufficient and even redundant.

It can be said that the location of this restaurant can even be fixed. Everyone has their own special place. Whether it is eating or reading and studying, this restaurant is also a place for leisure activities. If it were not for the large drainage volume, it would be impossible to waste it so much. ah.

Looking at the place in front of them, everyone was filled with emotion.

"There is a huge cold storage in the back." Kvasa continued to introduce to everyone: "Within one month of going to sea, the crew can eat a variety of fresh vegetables and fruits. Starting from the second month, they can eat a variety of easy-to-store foods. Food, after three months, you can still eat canned food.”

The food standard for submariners is the same as that of pilots, because the conditions for their survival are the worst. Once they go to sea, they may be underwater forever in the dark. If they do not have enough psychological quality, they may suffer from mental illness. Of course, the diet cannot be shabby.

However, due to limited conditions in the past, after sailors went to sea, all kinds of food would fill up all the space. Even around the beds where they slept, there were things like sausages hanging around. Every unused corner had to be used. When you get up, the first thing to be consumed is fresh things, fruits, vegetables, etc. After these are consumed, you start to eat potatoes and other things. Sometimes, you also have to eat moldy things.

Want to say that there is a special cold storage to store food? That will make people extremely emotional, this condition is great!

A 17,000-ton underwater monster has so much space! It can feed more than a hundred people, and of course there is enough space to store all kinds of grains, vegetables and fruits. With a special cold storage, you can eat fresh vegetables and fruits every month, which is pretty good!

"Because it is a nuclear submarine, it has abundant power, so submariners can have hot meals at any time." Kvasa continued.

In the past, diesel-electric submarines didn't even have to think about it. When the snorkel was deep, the battery had to be fully charged in the shortest possible time. When underwater, the power of the battery had to be conserved. Therefore, when on the submarine, one often needed to eat cold water. Rice, everyone in this situation has a deep understanding of it.

A nuclear submarine is enough, not to mention that this kind of nuclear submarine has two nuclear reactors. Even if it sails at full power, there will be a certain power surplus. Three meals a day, all are hot!

"The dining space is very large, so the accommodation space should also be large, right?" Someone thought of something.

"Yes." Kvasa said: "In terms of accommodation, our submarines not only cancel hot bunks, but also have bunk beds."

In the past, the internal space of submarines was limited, so the sleeping space was also very small. Not only were there three-person bunks in the upper, middle and lower bunks, each person could only get in and could not raise their head. Moreover, this bunk could not be occupied all the time. Each person is assigned a sleeper, and within a day, the three people take turns switching. There is always someone sleeping in the sleeper, so it is also called a hot bunk.

Now, with the increase in displacement, there is a lot of space inside the submarine. Therefore, the berths are all personal, where personal belongings can be placed, and they can also be converted into bunk beds. In this way, the vertical space is large, and people can at least sit up. , the feeling of sleeping will be much better.

"Come on, let's go take a look." Everyone was excited.

The places for eating and sleeping are all next to each other. After everyone entered, they saw the separated "single rooms." The single rooms were separated by vertical iron plates. There were two bunk beds on each side of the iron plate. There is an aisle in the middle of a single room and beds on both sides, thus forming eight-person rooms.

At the end of the partition, there is a foldable desk for the crew to read, write and use a computer. This spacious space is amazing.

"Eat well and sleep well so that submariners can have physical strength." Wu Shengli said with emotion: "On a submarine like ours, even if it stays underwater for three months, the crew can endure it. Under normal circumstances, , just one month of submersible, life is wonderful every day.”

You can eat fresh vegetables within a month, which is enough. After all, under normal circumstances, it only takes about a month for a submarine to go to sea, which is generally not too long. After nuclear submarines were built, all countries wanted to have the most fun. Long submersible record, Lao Maozi couldn't stand it after staying underwater for 45 days. The Americans stayed for 84 days. As for us, in 85, a 092 submarine set a record of 92 days, and the crew members all It was walking down.

At that time, it was used to break records, but now, it can be regarded as a normal mission. It is no big problem to go to sea and stay in such a comfortable environment for three months.

During World War II, German U2 submarines often went to sea for more than 12 weeks at a time, but most of the time they were in a floating state. Sailors could take a few breaths of fresh air in the control tower or on the deck, and feel like they were completely underwater. no the same.

"What's that little cabin over there?" someone asked, pointing to a strange-looking cabin.

These sleeping areas are separated by partitions, but the cabin has a door.

"That's the shower room over there." Kvasa opened the door: "There are six nozzles inside, which can accommodate six people taking a bath at the same time."

bath! You can actually take a shower on a submarine! Although this design has been reported before, now, hearing it with your own ears and seeing it with your own eyes still makes people feel incredible.

Looking inside, the space is not very big, and there is no place to change clothes, which means you have to go in naked and come out naked after washing. However, there are only men on the submarine, so there is no need to be too taboo. Six people at the same time, ten minutes each, can wash more than thirty or a hundred people in one hour, which can be done in three times, which just meets the needs of three shifts. After getting off the job, take a shower, and then With a good night’s sleep, three months of underwater life will pass quickly!
