Bright Sword Military System

The test went smoothly. Three missiles entered the air control area of ​​the anti-aircraft gun from different angles and heights, and were shot down by the anti-aircraft gun crew.

Lemon Lokoff is very satisfied with this result, and it can even be said to far exceed his expectations.

However, Lemon Lokoff and the few scientists he brought seem to be more interested in not this result, but the two machines that can calculate the data in an instant and give the parameters of the anti-aircraft gun.

"Comrade Commander!" Lemon Lokoff asked Wang Xuexin in surprise: "What kind of machine is this? Can you tell me how it works? It's amazing, it can calculate the parameters of anti-aircraft guns..."

Of course, Wang Xuexin would not say anything. No mission information in this regard should be disclosed. He could only answer: "Sorry, Comrade Lemon Lokov, I said this is our top military secret, so..."

Lemon Lokov nodded to express his understanding, and then looked at the computer enviously and sighed: "I can't believe it, Comrade Leader, you have developed such an advanced thing. If you didn't see it with your own eyes, I can't even believe it exists in this world!"

As he spoke, he raised his head to a few bear scientists who were looking left and right at the computer, and said, "I'm not afraid of your jokes. On the way here, they thought it was impossible for there to be any radar that could detect them together." Calculate the trajectory within seconds and give it to Zhu Yuan, you have taught them a lesson and let them see how big the world is, Comrade Commander!"

The so-called "the world is so big" should be that there are people outside the mountains and people outside the mountains in Huaxia language. Lemon Lokoff is not very proficient in the use of Chinese idioms.

Wang Xuexin knew that Lemon Lokov was still playing tricks on him... If someone is weak-willed or not smart enough, he will be overwhelmed by such a compliment from Lemon Lokov, and he will return after he relaxes his vigilance. Said: "Of course, our machine uses a unique certain technology..."

This is the case with previous transactions between countries. There may be traps at any time, and if you accidentally fall into it, the other party will take advantage of it.

Wang Xuexin is not that stupid, he just replied: "That's why it only cost 500 million US dollars, Comrade Lemon Lokoff, and our chief always thought that the sale was a loss. He thought we could obviously sell Yingjiang for more money or even Cash, why do you need to..."

"Comrade Commander!" Lemon Lokov hurriedly replied cautiously: "Please tell the chief that it is also beneficial to trade with us. We can transport more equipment and ammunition to you in a timely manner! This is something Yingjiang cannot do. of!"

Wang Xuexin nodded with a reluctant expression, and said, "That's all I can say! But...we can't stop doing business with Yingjiang forever, right?"

"Of course!" Lemon Lokov replied: "We hope that... your army will not sell this radar until at least the victory of the Battle of Stalingrad!"

Lemon Lokoff has his own reasons for saying this. From the perspective of Mao Xiong, of course he doesn’t want Hans to know that there is this radar. This is a strategic deception that can win more for Mao Xiong. time and benefits.

In fact, from Wang Xuexin's point of view, he would not want to do business with Yingjiang or Sunbuluo for a while, and he didn't even want them to know...

Just kidding, both Eagle Sauce and Sun Never Set are countries with computers. Once they know that computers can still be used in this way, they don't need to buy them at all, and they develop them by themselves.

But if Wang Xuexin made a vacuum tube computer and used it in artillery, the situation would be different.

It is said that when Lemon Lokoff reported the test situation to the Supreme Deputy Commander, the Supreme Deputy Commander was in a meeting. After he casually asked the messenger to read the telegram, the entire conference room was aroused.

The top deputy commander said excitedly: "I didn't expect this kind of equipment to exist. Mao Xiong is saved. He once again saved us at a critical moment by himself!"

In fact, the gun detection radar at this time has not yet met the requirements. The most serious thing is that the success rate of interception during the dive phase is low, as Wang Xuexin said before.

Afterwards, Su Xin, Su Liguo and others calculated and found that there was really a problem with the interception at this stage.

This calculation is not difficult, so Lemon Lokov and others came to a conclusion as soon as they left Su Xin. She ran to Wang Xuexin in a little panic and said a series of words:
"Captain, we have calculated that the maximum speed of the missile when it dives can even reach 600 kilometers per hour!"

"Although our radar can detect missiles tens of kilometers away, the range of Maoxiong's anti-aircraft guns is only 10 kilometers!"

"If the missile passes through the anti-aircraft airspace with the maximum path, the reaction time is only 2 minutes, but in actual combat, it is only 1 minute or less!"

……

Wang Xuexin understood what Su Xin meant.

The anti-aircraft artillery control zone is a hemispherical area drawn with the antiaircraft artillery as the center and 10 kilometers effective range as the radius. Only when the missile passes through the center of the sphere from a certain point on the sphere and then passes through another point can it have a 20-kilometer path.

And this is impossible.

In actual combat, the missile crosses a straight line obliquely across the hemispheric surface. Most of the time, this straight line is only about 10 kilometers, which means that the reaction time left for the antiaircraft artillery unit is only 1 minute.

If the computer has calculated the target trajectory in advance and let the antiaircraft artillery unit set the parameters and shooting height, then there is no problem. The antiaircraft artillery unit can already fire many shells within 1 minute.

The problem is...

"What's more serious!" Su Xin said: "Missiles often enter the dive phase about ten kilometers away from the target. At this time, the trajectory of the missile will completely change, that is to say... the trajectory position predicted by the computer before and thus obtained All the elements that are released will be invalid!"

Wang Xuexin nodded, he also thought of this question.

The computer is not a fairy, it can only predict the future trajectory of the missile based on its current flight trajectory, but if the missile suddenly changes from a flight state to a dive state, that is, it changes its trajectory, then all the predicted data will be overturned Do it all over again.

Then the problem becomes serious: everything, including observation, calculation, communication, artillery operation, etc., must be completed within this 1 minute.

Otherwise, there will be a "boom"...

It is basically impossible to complete these within 1 minute.

The gun detection radar may be able to respond quickly, and it only takes five seconds from observation to data.

But for the rest of the time...it takes at least 1 minute for the commander to report the elements to the antiaircraft artillery unit and then for the antiaircraft artillery unit to adjust the elements and shoot height according to the data.

At this time, even if it is adjusted, it is meaningless, because it is too late to shoot the shells out.

Wang Xuexin was a little frustrated. The artillery detection radar for missiles seemed to have entered a dead end.

The irony is that Mao Xiong doesn't know about it yet, and still has great expectations for it and even regards it as a life-saving straw...
