Chapter 734 052D’s technical upgrade

Only one ammunition elevator is modified, so the change is minimal. Moreover, if an accident occurs, it can easily be replaced by other elevators, which will not affect the combat effectiveness of the aircraft carrier. It can be changed back during the overhaul, and the workload is relatively small. , if the lift of the carrier-based aircraft is modified, it will be a big project.

Hearing Qin Tao's arrangement, Wu Shengli nodded: "Well, in this case, we can give it a try."

Ma Ming knew that this was already the best solution. Although he was looking forward to a comprehensive replacement, other engineers and naval leaders all had concerns, so he could only take one step. Next, when we get to the aircraft carrier, this only electromagnetic ammunition elevator will show its excellent performance, so that other people can give up their concerns and it can be fully adopted by the next aircraft carrier.

 “Horse, what do you think?”

Hearing Qin Tao's question, Ma Ming nodded: "I think it's okay."

“Well, let’s do that. By the way, we have made some progress recently regarding electric vehicles. Next, Secretary Zhao will introduce it to you.”

Ma Ming followed Zhao Ling away, while Qin Tao and Wu Shengli stayed here and continued to watch. Amidst the sparks of the arc, the welding seam kept moving forward at a speed visible to the naked eye. The welding speed was really fast. Got it!

“In the past, we would never have imagined that this welding work could be performed automatically using a robotic arm.” Wu Shengli said with emotion: “The progress of this technology is so fast.”

"Of course. Whether it's shipbuilding or aircraft building, there are mechanical arms, just like riveting. In the past, it was done manually, but now it is slowly replaced by machines. The spacing of the rivets is exactly the same, which is much more accurate than manual work. .”

 This is the progress of science and technology!

"Mr. Qin, Wen Gong is at the destroyer. Next, would you like to go over and take a look?" Xu Zhengyang came over and whispered to Qin Tao.

 Have you heard of Wen Xue? Qin Tao nodded: "Of course, let's go and take a look! Dad, after seeing the aircraft carrier, how about we go on to see the Aegis battleship?"

The third Aegis warship has been produced, and the navy has lost the excitement it once had. However, this kind of warship is still the backbone of the navy. Therefore, when Qin Tao said this, Wu Shengli nodded immediately: "Okay, let's Go over and take a look!”

On the slipway, the hull construction work of the 052C destroyer is at the end, and the hoisting work of the power system is in progress. Wen Xueyou and others are standing there to direct.

“Mr. Wen, when did you come here?” Qin Tao asked Wen Xueyou, “What have you been busy with recently?”

"What else can we be busy with, of course, ship gas turbines." Wen Xueyou said: "We discussed last time that we would develop a 100-megawatt gas turbine. With the funds from Mingzhou Group, we have started pre-research. , but it’s very difficult and there hasn’t been much progress yet.”

Qin Tao nodded: "It is quite difficult to increase from 20 megawatts to 100 megawatts. Now, we have new opportunities."

"What opportunity?" Wen Xueyou was looking forward to it. He had known for a long time that there would always be many surprises when he was with Mr. Qin. Mr. Qin had always been paving the way for them.

"We have contacted Ermao's Motor Sich Company and plan to develop a gas turbine based on their D-18T turbofan engine. The initial power can reach 40 megawatts. After subsequent improvements, the power will be doubled. It’s also possible.”

Wen Xue felt excited for a while: "Really? That's great! Now, the only thing we can get is the GT-25000. The power has been increased to 26.7 megawatts, and it has suddenly transitioned to the 40 megawatt level. A huge improvement.”

"What? You guys have already matured the GT-25000?" Now it was Qin Tao's turn to be surprised.

At present, the Navy's Aegis battleship still uses GT-15000, with a power of only 20 megawatts. In order to allow the battleship to have a speed of 30 knots, the displacement is limited to 6,000 tons. Now, the power has been increased to 26.7 megawatts, which means What?

 The displacement of the battleship can be further increased to more than 7,000 tons!

 An extra thousand tons of displacement can be used to do a lot of things, including carrying more electronic equipment, more weapons, and better living conditions...

"Yes, just before I came, this gas turbine had passed the durability test and could be equipped on the navy's warships at any time." Wen Xueyou said.

“Dad, our Aegis battleship can be improved!” Qin Tao said: “We can make this battleship have stronger performance!”

Wu Shengli nodded: "After the visit here, come back to the capital with me. We need to formally propose it at the naval meeting!"

The third 052C will be launched soon, and the fourth 052C is under construction. For this first batch of Aegis warships, four ships will be enough, and then the second batch of modified warships will come!

"Since we have to report on our work, we can't be in a hurry." Qin Tao said: "I need to go to the 14th Institute to see the progress of radar research and development, and then go to relevant units to see the progress of missiles and launchers. Since we want to make changes, we must Let’s make a big change!”

Originally, according to Qin Tao's suggestion, this kind of construction work required bidding, but now, since this warship is only a modification of the 052C, it can of course be built by the Mingzhou Group, and everyone knows it. , Mingzhou Group is the strongest, and leaving it to them is the most appropriate choice.

Wu Shengli agreed: "Then I'll wait for you in the capital."

  A week later.

  Time flies by so fast, before I know it, it is already the autumn of 1998. Autumn is the harvest season!

In the Huanglou conference room of Gongzhufen, a large number of naval leaders were sitting, and they were all discussing excitedly. Not long after, the door opened outside, and Qin Tao came in with a large group of engineers.

“Everyone, I’m very sorry, there’s a traffic jam on the road.” Qin Tao said, “I’ve kept you waiting for so long.”

“It’s okay, we won’t be late for a good meal. We can afford to wait for this good thing.” A leader said: “Mr. Qin, would you like to sit down and have a cup of tea first, and then introduce it to us?”

Qin Tao shook his head: "No need, I will show our 052D design plan to the leaders now. After the introduction is completed, the engineers of each sub-system will introduce it to everyone in detail."

 The projector lit up, and a beautiful warship design appeared on the projection screen.

“It looks similar to our existing warships.”

"Yes, for simple transformation, we directly increased the displacement by simply enlarging the hull. Our 052C destroyer is 153 meters long and 16.5 meters wide. Now, our 052D destroyer is 155 meters long and 17.5 meters wide. meters, this will increase the full load displacement to 7,000 tons. If you want to improve it later, you can just lengthen the hull slightly."

Compared with the length, the width has increased by a larger proportion. This is also in line with the trend of the times. In the past, warships pursued high-speed performance and had a large aspect ratio. Warships were elongated. Although the speed was high, the space was small and the seakeeping was poor. The swaying in wind and waves is serious. Today's warships are developed horizontally and have a small aspect ratio. This way, the warships have more space and can sail easily in wind and waves. Anyway, if you have enough power, you can build it like this.

"The overall layout is similar to the original one. The bow is the naval gun, and behind the gun is the vertical launch unit. Then there is the bridge, chimney, and auxiliary mast. After these, there is our second set of vertical launch units. And then Helicopter hangar and flight deck." Qin Tao introduced it from the front to the end in one breath: "Okay, my introduction is completed. Now, let us introduce the upgrade project to the leaders from front to back, starting with the ship The cannon starts."

"Dear leaders, the H/PJ-38 single-barreled 130mm naval gun we developed has been installed on the 052C destroyer. With advanced design concepts, it has become the standard equipment of domestic destroyers. Its appearance has been modified for stealth model, and its reliability has been further improved. At present, its biggest change is the addition of a new type of ammunition." Xia Bei, the naval gun manager of the 713 Institute, introduced excitedly.

The 713 Institute is the main research and development unit of domestic naval guns. Many naval guns of the Navy come from their units, such as 37mm naval guns, 57mm naval guns, 76mm naval guns, 100mm naval guns and now 130mm naval guns. A few years ago, the AK630 naval gun they copied was once the main close-in defense gun of the navy, but later it was surpassed by the 730 naval gun of the brother unit. However, they did not admit defeat and kept working hard to make further progress in naval guns.

“A brand new type of ammunition? Are there any other types of artillery shells that we haven’t heard of?” The naval leaders became curious.

"Everyone knows that when our gun fires ordinary shells, its maximum range is less than 30 kilometers, and it can't hit 50 kilometers when it fires bottom volley shells. But now, we have added a new rocket gliding guidance to it. The maximum range of artillery shells is..." Xia Bei glanced at the people present proudly, deliberately paused to attract everyone's attention, and then continued: "One hundred and twenty kilometers!"

What?

 Some naval leaders even stood up: "What did you say, one hundred and twenty kilometers?"

YJ-82 anti-ship missiles have only hit this far. Now, naval guns can actually hit this far? If it were not at a formal meeting, everyone would definitely answer in unison: Impossible, this is absolute nonsense!

"That's right, one hundred and twenty kilometers. You can look at the next slide. The top is the appearance of the artillery shell, and the bottom is the ballistic table." Xia Bei said: "Our artillery shell uses a special rocket engine, and the thrust is more powerful. , if only rockets are used to extend the range, the range can reach 70 kilometers. If a longer range is required, then when the artillery shell flies to the apex of the trajectory, it will unfold the gliding wing at the front of the projectile. With the help of it, it began to fly a gliding trajectory, which greatly increased its range and could easily fly a hundred kilometers away!"

If there are no fins, the cannonball will continue to follow a parabola with air resistance. With the fins, the cannonball can fly farther!

Qin Tao knew that this should be inspired by the gliding aircraft flying Qian Xuesen's ballistic trajectory from the Second Artillery. He was very satisfied. Now, even without his promotion, domestic scientific research forces can start working normally and develop projects one by one. Out!

“It turned out to be floating over, but how can we guarantee that we can hit the target at such a long distance?” someone asked.

Naval guns are installed on warships, so there is no need to worry about movement. Therefore, in the battleship era, naval guns are getting bigger and more powerful. However, the range of naval guns has not been improved. This is of course because of the accuracy of the gun. The problem is, the range is far and the target is directly under the sea level, how can we aim?

I have almost never seen a naval gun with a range of more than 50 kilometers. Now the range has doubled to more than 100 kilometers. How can the accuracy be guaranteed?

"Leader, I just said that we are guided artillery shells!" Xia Bei said: "It not only has canards at the front, but also has four fins at the tail. These four fins are used to control the ballistic trajectory. Yes, as for the guidance system, we already have Beidou navigation, so we can use satellite positioning for guidance, we can also use laser semi-active terminal guidance, etc. In short, we can still achieve a target a hundred kilometers away. One hit will kill him."

 This naval gun is going to take away the job of the missile! Looking at its guidance system, you can know that the most suitable target is a fixed land target, which is good for long-range ground strikes. Even if a guided artillery shell is used, the cost of the artillery shell will definitely be less than that of the missile. If anyone is dissatisfied in the future, Just give him a lesson first!

"Okay, this naval gun has opened our eyes. In the future, our navy will have another big killer weapon when performing missions!" Wu Shengli sighed with emotion: "If the first few ships can be used, it will also be used." It can be modified.”

  If it is an ordinary artillery shell, then just replace it. However, this kind of artillery-launched missile is different. It requires a guidance system, which means that relevant equipment must be added to the warship's command and control system.

 So, it needs to be improved.

"Yes, the two ships built now can be added during outfitting. The previous two ships need to wait until the mid-term overhaul." Qin Tao said.

A small naval gun has so much knowledge. However, this is already the sunset of naval guns. Next, it is time to enter the era of electromagnetic guns. If nothing else happens, the 130mm naval gun will It is the last naval gun of the Navy.

“We have approved this plan. Next, let’s talk about the missiles at the back.” A leader said.

Following the order, behind the naval gun is the vertical launcher, and this vertical launcher was also developed by 713, so Xia Bei did not go down and continued to introduce it.

"According to President Qin's proposal, we have spent about three years studying the hot and cold co-rack technology. Now, this hot and cold co-rack has matured, so we plan to equip this destroyer with a hot and cold co-rack system. Launcher."

This device has been tested on a Navy test ship. Everyone knows that this thing exists. They are not as surprised as the rocket gliding guided artillery shell just now. However, some people still have concerns.

“The caliber of this launcher is too large. Will it reduce the carrying capacity of Hongqi Nine?”

This is also the only thing that the superior leaders are worried about. After all, the diameter of the honeycomb vertical launch system used on the 052C is about 0.6 meters, and the current hot and cold launch device has actually expanded to a diameter of 850 mm. It is so big , it will inevitably reduce the amount of shoelaces on the missile!

"Let me explain this." Qin Tao said: "Our 052C uses a silo layout of 32 in the front and 12 in the back. In this way, the total number of vertical launchers is 48, and it can only carry a single Hongqi-9 missile. This provides greater flexibility in mission execution. Very bad, and now, we are using a 32-inch launcher at the front and a 32-inch rear launcher, so the overall number of vertical launchers has been expanded to 64 units. Although the size of our launcher has become larger, it is said that the size of our warships has also increased!"

The width of the warship is increased by one meter, which greatly helps to increase the width of the launch silo. The front is 4*8, and there are four horizontally. Each increases by 0.25 meters, which increases the width by exactly one meter. Moreover, the original The honeycomb briquette launcher was a serious waste of space. Now it is changed to a cube, and the space utilization efficiency has been improved.

 So, no problem at all.

"Under normal circumstances, in order to achieve the air defense capabilities of the 052C, we can carry 48 long-range air defense missiles. In this case, we have 16 silos left that can be freely matched, eight of which can be used Loading the Hongqi 16 with two bombs in one pit will provide 16 medium-range air defense missiles, and the remaining eight silos can be used to match anti-ship or anti-submarine missiles, or even future anti-ship ballistic missiles."

The leader nodded. In this way, the air defense capability will not be reduced, and the execution of tasks will be more flexible. Anyway, the displacement will be increased. If you want to do this, then let's do it.

"Dear leaders, let me continue the introduction." Xia Bei said: "Our vertical launch system is very flexible. It can be launched hot or cold. At the same time, it can accommodate three missiles. There are three different lengths, including 9 meters, 7 meters and 3.3 meters."

Not only has its diameter increased, but its depth has also increased. Of course, limited by the curvature of the bow, the depth of the four launch units on both sides of the bow cannot reach 9 meters, but the depth of 7 meters Not too young anymore.

You must know that the depth of the previous briquette launcher was only 7 meters, which was enough to launch the Haihongqi 9 missile. This 9-meter launcher was prepared for the big guys in the future.

 For example, the YJ-18 anti-ship missile, the Changjian-10 cruise missile, and even specially developed anti-ship ballistic missiles, extra-atmospheric anti-missile interceptors, etc.

The 7-meter vertical launcher can be loaded with Haihongqi-9, Yu-8 anti-submarine missiles, and Hongqi-16 with one pit and two bombs, etc. It is the most widely used. As for the depth of 3.3 meters, it is reserved for the future. A missile with four bombs in one pit is small in diameter and must be small in length, which is exactly within this range.

“Back then, we envied the Americans’ MK41 vertical launch system. Now, it’s finally their turn to envy us.” A leader present said with emotion.

When the MK41 vertical launch system was gaining traction, our own side only had point-defense missiles like Sea Sidewinder. At that time, they did not dare to leave the radius of activity of land-based aviation. Later, with the imported Rif-M and imitation and improved briquettes, Later, a thermal emitting device was installed on the frigate. Step by step, we finally have a more compatible hair hanging device.

 The quantity is sufficient and the flexibility is enhanced. What else is there to be dissatisfied about? You must have it!

“Next, let’s talk about radar, right?” Wu Shengli asked.

“Not yet, behind the vertical launching device is the close-in defense cannon. Let’s ask our close-in-defense cannon R&D unit to introduce it to you first,” Qin Tao said.

Xia Bei finally went down. If it were in the past, they were also engaged in close-in defense artillery, but now, the performance of their six-barrel close-in defense artillery can no longer meet the needs of the navy. Fortunately, their 130 mm naval gun and vertical launch system are very powerful. He has nothing to regret.

The 847 factory they were bidding for finally had the last laugh.

Factory 847 originally manufactured aerial cannons for aircraft. After entering the missile era, aircraft designers felt that aerial cannons were useless for a long time. Later, although aerial cannons were mounted again, they were just a Spare, just like a car's spare tire, the driver never wants to use the spare tire.

Therefore, they had to transform. They aimed at the close-in defense guns used by the navy. In the mid-1980s, they decided to develop the 730 naval gun. After a comprehensive evaluation by the navy, the project was officially launched and was named Project 857.

However, it is not easy to develop a close-in defense gun from scratch. They encountered many problems during the research and development, and then were intercepted by the 713 Institute. The 713 Institute imitated the AK630 through surveying and mapping, and was recognized by the Navy. The equipment is in On the warships built in the past few years, Factory 847 was not discouraged. After years of polishing, they finally built their close-in defense cannon.

 The 052C currently being built uses the 730 naval gun, so the naval leaders also know it. They are very curious, what else can be said about this close-in defense gun?

The reason why the 730 naval gun is recognized is its high accuracy. The 630 naval gun uses internal energy, that is, it uses the gas of gunpowder to promote rotation and has large vibrations, while the 730 naval gun uses external energy, with small barrel vibration and higher accuracy.

"Dear leaders, we continue to improve on the 730 naval gun. The product currently developed is the 1130 naval gun. You should know from the name that this naval gun is an upgraded version of the 730 naval gun. The number of barrels has been upgraded from 7 to 11. , and the rotation speed is faster. In this way, our close-in defense cannon's firing rate has finally reached the hard target of 10,000 rounds per minute." The person in charge of the close-in defense cannon said to the sky.

 Everyone opened their eyes wide.

 Ten thousand rounds per minute? Hard indicator?

 Do you know what this means?

 One of the leaders present spoke: "In other words, once this kind of gun fires, even if it only fires for a second or two, it will cost hundreds of thousands!"

The navy burns money, not to mention those expensive missiles, which are just naval guns and cannot be used anymore. Although the shells of naval guns are not expensive, they cannot bear the high price.

“What the leaders are talking about is the price of ordinary artillery shells. If we fire our special sabot-piercing projectiles, it will cost about 500,000 yuan per fire.” Xiang Tian was very honest.

Even if you stop firing just after firing and shoot a shuttle, it will still cost you 500,000 yuan!

“Then why are you doing this? Do you want to make the navy pauper?”

"In order to intercept supersonic anti-ship missiles flying at low altitudes and skimming the sea." Xiang Tian said: "The interception capability of our close-in defense artillery is an order of magnitude higher than that of the Phalanx."
