Chapter 152 Old Maozi wants to deal with the rags?

Qin Tao continued to talk there: "We have suffered enough from towing chassis. We can't go on all kinds of bad roads. We don't have real field air defense capabilities at all. The kind of off-road chassis you exported to Eastern Europe is the only one." It’s our best choice. Shouldn’t we just spend more money? No matter how poor we are, we can’t afford national defense, and no matter how miserable we are, we can’t afford the army. We can afford this money!”

 Efimov's face looked a little ugly.

When the delegation that went to the Chinese capital to negotiate sent back the news that the Chinese wanted to purchase S-300 missiles, they were very happy. After all, this would allow them to obtain a large amount of funds, even if it was just barter. , those good things are also what they need most.

However, they also need to be careful. Advanced weapon systems cannot be exported to China. Therefore, they immediately thought of the S-300PT. This initial model, which has been eliminated, is most suitable for selling to the Chinese.

Who would have thought that the person in front of me was so confused that their towed weapon system was not good!

Ben Jing looked at Mr. Wu and said: "My old friend, what do you think? Let me tell you, this kind of trailer chassis is already very good."

Although Qin Tao insisted there, Qin Tao was too young after all, so he could not be the leader of this delegation. Ben Jing already knew that Mr. Wu was the leader, so the real decision-making power rested with Mr. Wu. of.

Mr. Wu glanced at Qin Tao, who was still insisting, and said, "His opinion is my opinion."

Although Mr. Wu still doesn’t know what is going on, he believes that since Qin Tao insists on self-propelled chassis, there must be a reason for him.

 Mr. Wu has great trust in Qin Tao.

At this time, Qin Tao had already walked to the trailer chassis and looked at the flat-panel antenna on it.

 The launch tube is nothing fancy, it is just an ordinary launch tube, and various types of missiles can be stuffed into it.

The weapon system Lao Maozi first developed was the 5V55K (Russian 5В55К) with a range of 47 kilometers. The guidance method was also backward radio command guidance. Later, an extended-range version of the 5V55KD with a range of 90 kilometers was launched (Russian 5В55КД). At the same time, the guidance method has also been changed to more advanced semi-active guidance.

 Anti-aircraft missiles all require the cooperation of radar. When Lao Maozi was developing the S-300 system, he had already decided to use phased array radar.

Ordinary radar scans by changing the direction of the antenna, just like a flashlight. When you turn the flashlight, the beam will follow. For phased array radar, what changes is not the orientation of the radar antenna, but the phase of the radar wave to achieve the scanning effect, so the radar antenna can be fixed.

Early radars all used phase shifters, and the back was still an ordinary radar transmitting tube. The emitted electromagnetic waves passed through the front phase shifters (mostly ferrite) to change the phase of the radar waves. This passive Phased arrays are very bulky. In the later stage, with the development of microelectronics technology, it was possible to make a small component (T/R component) with the ability to transmit and receive electromagnetic waves. By combining these things on a flat panel, an active phased array was created. radar.

Lao Maozi is not capable of making an active phased array radar. Even their MiG-31 has to carry such a big thing. What Qin Tao saw in front of him was a rectangular passive phased array radar antenna.

“Your Excellency Yefimov.” Qin Tao pointed at this radar antenna and said, “Why do I feel that it has a smaller area than the radar installed on the self-propelled chassis?”

When Qin Tao pointed it out, Mr. Wu had already realized that the S-300 system of this kind of trailer chassis must be different models from the system of self-propelled chassis!

"Is it my imagination?" Qin Tao didn't wait for Yefimov to speak. He strode over and wiped a certain position on the side of the trailer with his hand, wiping off the snowflakes on it and revealing a nameplate inside. Come.

"5N63 radar." Qin Tao read out the Russian number on it, and then said: "Is this the same type of radar you export to Eastern Europe? It doesn't seem like it."

Of course it's not like that. This kind of radar was the earliest radar system used by the S-300PT system. It had backward performance and short search range. Therefore, after the development of the S-300PS, the radar was changed to 30D6 and exported to Eastern Europe's S -300PMU also uses this kind of radar system. Looking at the area alone, the latter is larger, has greater power, has a long search distance, and has strong anti-interference ability.

Even the 30D6 is still not powerful enough, so after entering the 1990s, Lao Maozi developed the 64N6 radar. The performance of this radar is very powerful, and it can guide missiles with a range of 400 kilometers.

The Red Empire has not collapsed yet, and the model of Lao Maozi's S-300 weapon system is also confidential. Qin Tao cannot point out that the model used by the other party is wrong, but he can intuitively tell the size of the area!

Yefimov did not speak. He would have polished off all the nameplates before the Chinese delegation came! If the other party went to Bulgaria or Czechoslovakia to inquire, the secret would be exposed.

He couldn't deny Qin Tao's judgment, for fear of being slapped in the face later, but if he admitted it, he would be slapped in the face immediately.

Lao Maozi's embarrassment was seen by everyone. Everyone had already guessed what was going on, and their faces were a little aggrieved. We came all the way, braving the severe cold in Moscow, and in the end, what did Lao Maozi do to us? ? He actually fooled us!

 Thanks to Qin Tao, I saw the trick played by Lao Maozi!

"My old friend, the weather outside is too cold. Let's stop today's inspection for now. Let's go have a drink. How about we continue tomorrow?" Ben Jing said.

Looking at Ben Jing’s face, Mr. Wu nodded: “Okay, we’ll do it tomorrow. However, tomorrow we ask to see the S-300 system on the self-propelled chassis.”

Since you want to buy it, you must not buy an outdated model.

“Let’s talk about this tomorrow, let’s go drink now.”

 Li Daming’s happy time has come again.

The last time I came to Lao Maozi, it was the most prosperous time for Li Daming. When Lao Maozi came to the capital later, he seemed to have learned the lesson and stopped drinking with Li Daming at all. Therefore, Li Daming, the professional bartender, also Became a lonely man seeking defeat.

 The people here didn’t seem to know him, so he was able to drink openly.

Li Daming was very excited as they drank glass after glass of fine wine, while the old men were soon drunk.

"Your Excellency Benjing, you are the designer of the S-300 system. We young technicians all admire you." Qin Tao came to Benjing with a wine glass and looked at Benjing who had drunk too much. Said: "On the way here, Mr. Wu introduced many details of working with you. He misses those passionate days very much."

Mr. Wu was not very good at drinking, so after a few drinks he was helped away, leaving the place to Qin Tao. Anyway, with the **** of wine around, he didn't have to worry about getting these people drunk.

At this time, while he was still drunk, Qin Tao began to talk.

“Yeah, I miss those days too, so when I heard that you were coming, I came over in person.”

 “Come, I hope our friendship will last forever!”

 Another glass of wine.

Qin Tao continued to compliment: "We have noticed that your S-300 missile system is very similar to the American Patriot missile system. However, it seems that the American technology is more advanced. For example, in terms of terminal guidance of the missile, Patriot missiles use TVM technology."

TVM (Trackviamissile), literally translated as "guidance via missile", it is customary to call it "command + homing" guidance.

 Early missiles were guided by radio commands. Similar to model aircraft, the radar station transmitted control signals to the missile and guided the missile to fly to the target. Lao Maozi's 5V55K also used this method.

However, radio commands are susceptible to interference, so semi-active radar guidance later appeared. The rear radar is responsible for illuminating the target. After the radar wave is reflected by the target, it enters the antenna in front of the missile, modifies its trajectory, and continues to fly towards the target. If the missile's own antenna can also emit electromagnetic waves, it is active radar guidance.

With the continuous development of technology, this combined guidance method has emerged. This TVM guidance method combines the advantages of both.

The ground guidance radar emits a radar beam to illuminate the target and guide the missile forward. When the missile approaches the target, the missile's antenna receives the radar illumination signal scattered by the target. At the same time, it measures the precise angle of the target relative to the missile, and then transmits the measured coordinate data through the data link. It is sent back to the radar vehicle, and after processing by the radar vehicle, the missile control instructions are sent to allow the missile to hit the target more accurately.

At present, this technology is only used by Patriot missiles. The S-300 system will not use TVM guidance until 1993, when the fourth 48N6E2 missile with a range of 200 kilometers is launched.

 (Two missiles have been introduced before, and in the middle of this missile is a 5V55U missile with a range of 150 kilometers, which was launched in 1992)

Hearing what Qin Tao said, Ben Jing immediately shook his head: "That technology is too complicated and meaningless. Even if the accuracy is worse, it doesn't matter. We can achieve the same effect by increasing the killing radius of the warhead."

This is the way of thinking of old men. It is difficult for them to rack their brains to improve the accuracy of weapons. Instead of wasting energy on improving accuracy, it is better to simply increase the power of the warhead.

The warhead of the S-300 missile weighs a full 133 kilograms. It can keep up with the warhead weight of some ground attack rockets. It is one-third higher than the warhead of the Patriot missile.

“So, what guidance method does the opponent’s S-300 weapon system use?” Qin Tao asked.

 The previous ones are all foreshadowing, to introduce the content that follows.

At this time, Ben Jing was already quite drunk, so that his words came out directly without going through his brain.

“We used radio command guidance in the first generation, and semi-active guidance in the second generation.”

“Then when you combine the two, does it become the TVM guidance method?”

“Of course not, the internal circuit needs to be modified and adjusted.”

“So, what kind of guidance method were shown to us today? I seem to have seen an antenna on the radar car specially designed to send radio commands.”

Ben Jing suddenly woke up. Oops, I said something I shouldn’t have said just now!

 He ​​did not leak any technical data, but only talked about some technical routes. However, just these things can already reveal different models.

 What they plan to sell to China is the first-generation system, but now, they are using a large number of second-generation systems and are developing third-generation systems!

Ben Jing has sobered up, but after what he said, he can no longer take it back.

 Late night.

After the banquet, everyone returned to the room. As soon as Qin Tao opened the door, he saw Mr. Wu sitting in front of the writing desk.

 Lao Wu didn't sleep, he was still waiting for Qin Tao.

Seeing Qin Tao come back, Mr. Wu put his hand on the record player, turned the record, and a majestic and powerful song came out.

 “How is it?” Mr. Wu asked Qin Tao in a low voice.

"Benjing spoke the truth after drinking." Qin Tao said: "What they showed us today is the first-generation S-300 system. The one exported to Eastern Europe should be the second-generation S-300 system. It is estimated that they still have We are developing a new generation of systems.”

Mr. Wu's face was ugly: "We don't ask them for the latest system, at least they must give us the same system as Eastern Europe. Tomorrow, we will ask for a self-propelled chassis system!"

 Su-27 can be sold by other parties, let alone S-300? As long as you persist, you will definitely gain something.

"Actually, it's okay to sell us the first-generation system, but those are already old rags. It's unethical to sell rags at rags prices. It's not authentic to sell rags to us as good things." Qin Tao said.

Qin Tao does not dislike rags. After all, he has been collecting rags since he came to this world. However, selling rags to him as good things would be a bit unethical, and Qin Tao would never agree with it.

At this time, hearing what Qin Tao said, Mr. Wu's eyes shone with hope: "Qin Gong, can you buy their first-generation system as junk?"

Although Mr. Wu is now here to discuss the introduction of the S-300 with the expectations of the Air Force, it is too expensive after all. The Su-27 has not been negotiated yet. It is probably also a sky-high price. We really can't spend money here. too much.

Besides, they don’t want to buy many sets to protect the sky of the motherland. The more important purpose is to buy them back, disassemble them for research, and then promote the research and development of their own related projects. Therefore, if Qin Tao can get them back at a low price, then he will do it again. It couldn't be better.

“Mr. Wu, I’ll try my best, but it’s very difficult, so we still have to be prepared.”

Even though Lao Maozi has replaced the PT with the S-300PS, after all, the PT only entered service in the army in 1978. It is still a relatively advanced weapon and equipment. It is not easy to get these things.

 Mr. Wu nodded. He also knew that it was very difficult, but he was full of expectations for Qin Tao. Qin Tao is a capable person and will definitely try his best to achieve this goal.
