Great warships

Chapter 151 The old man wants to deal with the broken?

Qin Tao was still eloquent there: "We've had enough of dragging the chassis. We can't go on all kinds of bad roads. We don't have real field air defense capabilities at all. The off-road chassis you exported to Eastern Europe are the only ones that you can use." It is our best choice. Isn’t it just to spend more money? No matter how poor you are, you can’t be poor in national defense, and no matter how hard you are, you can’t suffer from the army. We can afford this money!”

Yefimov looked a little ugly.

When the delegation that went to the Chinese capital to negotiate sent back news that the Chinese wanted to buy S-300 missiles, they were very happy. After all, this would allow them to get a lot of money, even if it was barter , Those good things are also what they need most.

However, they also need to keep a hand. Advanced weapon systems cannot be exported to China. Therefore, they immediately thought of the S-300PT, the original model that has been eliminated, and it is most suitable to sell to the Chinese.

Who would have thought that the person in front of him would be so stubborn, thinking that their towed weapon system is 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 couldn't be the person in charge of the delegation. Benjing already knew that Mr. Wu was the leader of the team, so the real decision-making power was with Mr. Wu. of.

Elder Wu glanced at Qin Tao who was still standing there, and said, "His opinion is my opinion."

Although Mr. Wu still doesn't know what's going on, he believes that since Qin Tao insists on doing the chassis by himself, there must be his reasons.

Mr. Wu trusted Qin Tao very much.

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

The launch tube is nothing fancy, it's just an ordinary launch tube, which can be stuffed with various types of missiles.

老毛子的这套武器系统，最先研制出来的是射程47公里的5V55K （俄语 5В55К），制导方式也是落后的无线电指令引导，后来又推出了射程90公里的增程版5V55KD，（俄语 5В55КД）同时制导方式也改用了更加先进的半主动引导。

Air defense 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 orientation of the antenna, just like a flashlight, turning the flashlight will cause the beam to rotate accordingly.For phased array radar, it is not the orientation of the radar antenna that is changed, but the phase of the radar wave to achieve the scanning effect. Therefore, the radar antenna can be fixed.

Early radars used phase shifters, and the back was still the transmitting tube of ordinary radar. The electromagnetic waves emitted changed the phase of radar waves through the front phase shifters (mostly ferrite). This passive Phased arrays are very bulky.In the later stage, with the development of microelectronics technology, a small component (T/R component) capable of transmitting and receiving electromagnetic waves can be made, and these things can be combined on a flat panel to form an active phased array. radar.

Lao Maozi is incapable of making an active phased array radar. Even their MiG-31 has to carry such a big guy. What Qin Tao saw in front of him was a rectangular passive phased array radar antenna.

"Your Excellency Yefimov." Qin Tao pointed to this radar antenna and said, "How do I feel that it is smaller than the radar installed on the self-propelled chassis?"

When Qin Tao pointed out here, Mr. Wu had already realized that the S-300 system of this kind of trailer chassis must be of different models from the system of self-propelled chassis!
"Could it be my delusion?" Qin Tao didn't wait for Yefimov to speak, he had already strode over, wiped a certain position on the side of the trailer with his hand, and wiped off the snowflakes on it, revealing a nameplate inside Come.

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

Of course not, this kind of radar is the earliest radar system used by the S-300PT system. The -300PMU also uses this kind of radar system. Looking at the area alone, the latter is larger, with higher power, longer search distance and strong anti-interference ability.

Even if it is 30D6, the performance is still not strong enough, so after entering the 90s, Lao Maozi developed the 64N6 radar. The performance of this radar is very powerful, and it is no problem to guide missiles with a range of [-] kilometers.

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

Yefimov didn't open his mouth. He knew that before the Chinese delegation came, he would have polished off all the nameplates!If the other party goes to Bulgaria or Czechoslovakia to inquire, it will be revealed.

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

The old man's embarrassment was seen by everyone, and everyone had already guessed what was going on, with a bit of indignation on his face. We came all the way here, braving the severe cold of Moscow. In the end, how did the old man treat us? ?How dare you fool us!
Thanks to Qin Tao, he saw the old Maozi's tricks!

"My old friend, the weather outside is too cold. Let's stop here for the time being. Let's have a drink. We'll continue tomorrow, how about it?" Ben Jing said.

Looking at Ben Jing's face, Mr. Wu nodded: "Okay, we will do it tomorrow, but tomorrow we ask to see the S-300 system of the self-propelled chassis."

Since you want to buy it, you must not buy a backward model.

"Well, let's talk about it tomorrow, and go drink now."

Li Daming's happy time has come again.

The last time I came to Lao Maozi's place, it was Li Daming's most beautiful time. When Lao Maozi came to the capital later, the other party seemed to have learned how to behave, and he didn't drink with Li Daming at all. It became Dugu Qiubai.

The people here don't seem to know him, so he can open up and drink again.

Li Daming was very excited as he drank one cup after another of fine wine, but the old men were quickly overwhelmed.

"Your Excellency Benjing, you are the designer of the S-300 system. We young technicians admire you very much." Qin Tao came to Benjing with a glass of wine, and looked at Benjing who had drunk too much Said: "On the way here, Mr. Wu introduced a lot of details about working with you. The old man cherished that passionate era very much."

Mr. Wu couldn't drink much, so after a few drinks, he was helped away and handed over the venue to Qin Tao. Anyway, there is Dionysus, so he is not afraid of getting drunk.

At this time, taking advantage of his drunkenness, Qin Tao started to talk.

"Yeah, I also miss those years very much, so when I heard that you were coming, I came here in person."

"Come on, may our friendship 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, but it seems that the American technology is more advanced. For example, in terms of the missile's terminal guidance, The Patriot missile uses TVM technology."

TVM (Track via missile), the literal translation is "guidance via missile", and it is customarily called "command + homing" guidance.

Early missiles were guided by radio commands, similar to model airplanes. The radar station sent control signals to the missile to guide the missile to the target. Lao Maozi's 5V55K also used this method.

However, radio commands are susceptible to interference, so semi-active radar guidance appeared later. 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 to 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 also appeared. This TVM guidance method combines two advantages.

The ground guidance radar emits radar beams to illuminate the target to guide the missile forward. When the missile approaches the target, the antenna of the missile receives the radar irradiation signal scattered by the target, and simultaneously measures the precise angle of the target relative to the missile, and then passes the measured coordinate data through the data link. Send it back to the radar car, and after the radar car processes it, it will send the missile control command to make the missile 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 200N48E6 missile with a range of 2 kilometers is launched.

(Two missiles have been introduced earlier, and in the middle of this missile, there is also a 150V5U missile with a range of 55 kilometers, which was launched in 92)
Hearing what Qin Tao said, Ben Jing immediately shook his head: "That kind of technology is too complicated and meaningless. It doesn't matter if the accuracy is poorer. We can achieve the same effect by increasing the killing radius of the warhead."

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

The weight of the warhead of the S-300 missile is a full 133 kilograms.That's about as heavy as the warhead of some ground-attack rockets.It is one-third higher than the warhead of the Patriot missile.

"So, what kind of guidance method does the opponent's S-300 weapon system use?" Qin Tao asked.

The previous ones are all foreshadowing, which is to lead to the following content.

At this time, Ben Jing was already drinking a little too much, so that his words came out without going through his brain.

"We used radio command guidance for the first generation, and semi-active guidance for the second generation."

"Then you combine the two, is it the TVM guidance method?"

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

"So, what is the guidance method that was shown to us today? I seem to see that there is an antenna on the radar vehicle that is dedicated to sending radio commands."

Ben Jing suddenly woke up, it's too bad, I said something I shouldn't have said just now!

He didn't disclose any technical data, just said some technical routes, but just these things can already reveal different models.

What they plan to sell to China is the first-generation system, but now, they are serving a large number of second-generation systems, and they are developing the third-generation system!
Ben Jing is already sober, but he can't take back what he said.

late at night.

After the banquet, everyone went back to the room. Qin Tao just opened the door when he saw Mr. Wu sitting in front of the desk.

Old 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, the record was spinning, and a majestic and powerful song came out.

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

"Benjing spits out the truth after drinking." Qin Tao said: "What they showed us today is the first-generation S-300 system, and the one exported to Eastern Europe should be the second-generation S-300 system. A new generation of systems is being developed.”

Old Wu's face was ugly: "We don't ask for their latest system, at least give us the same system as Eastern Europe. Tomorrow, we will ask for a system with our own chassis!"

The Su-27 can be sold by the other party, let alone the S-300?As long as one's own side persists, there will be gains.

"Actually, it's okay to sell us the first-generation system, but those are already old men's rags, and they will be sold at rag prices. Selling rags to us as good things is not authentic." Qin Tao said.

Qin Tao doesn't dislike rags. After all, he has been collecting rags since he came to this world. However, selling him rags as good things is a bit unethical, and Qin Tao will never agree.

At this time, after hearing what Qin Tao said, Elder 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 expectation of the Air Force, it is too expensive after all. The Su-27 has not yet negotiated, and it is estimated to be a sky-high price. It is really impossible to 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 and disassemble them for research, and then promote the research and development of their own related projects. It couldn't be better.

"Mr. Wu, I'll try my best, but it's very difficult, we still have to make two preparations."

Even if Lao Maozi has replaced PT with S-300PS, after all, PT began to serve in the army only in 78, and it is still relatively advanced weapons and equipment. It is not easy to get these things.

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