In fact, this is not just a matter of "one second".
This is what Wang Xuexin said to Lemon Lokov: "Your 52K 85MM anti-aircraft gun has an effective range of 10 kilometers, and the anti-aircraft gun is basically not equipped with radar. It depends entirely on the gunner's vision and experience, right?"
"Yes!" Lemon Lokov nodded, then shook his head and said, "Actually, we have a sound wave detector, but the effect is not very good. It can only detect aircraft about eight kilometers away.
!”
Eight kilometers... this distance can be seen by observers equipped with telescopes.
However, this kind of acoustic detector is useful at night and in bad weather, when observers can hardly see anything.
"It is much easier to equip this radar!" Wang Xuexin said: "The detection range of this radar for missiles or aircraft is about 30 kilometers. Once it detects the target, it can immediately calculate the target's flight trajectory. That is to say
You know the airspace of which anti-aircraft gun position the missile will pass through as soon as possible and prepare in advance. Do you know what this means?"
Lemonlokov didn't react at first, but after thinking about it carefully, he exclaimed: "Comrade Commander, you mean... we can use all the time when the target flies over the anti-aircraft artillery position?"
Wang Xuexin nodded.
Without radar or computer-aided calculations, the entire reaction time of the Bear Artillery was three minutes or less.
The Mao Xiong artillerymen have to complete everything within these three minutes, including about one and a half to two minutes of gunnery time. In the remaining minute, they can fire more than a dozen shells... The 52K theoretical rate of fire is 20 rounds per round.
Minutes, the actual rate of fire is only 12 rounds, and this is the data of a well-coordinated gun crew.
(Note: The operation of anti-aircraft guns during World War II was much more difficult than in modern times. The most difficult and time-consuming part was to judge the height of the target and then manually adjust the explosion time of the shell fuse)
But if there is radar and computer assistance, all these actions will not be done within three minutes after the missile enters the range of the anti-aircraft artillery. Instead, the anti-aircraft artillery unit can prepare in advance and even know Zhu Yuan and She Gao... This was done before
It is unimaginable, because there is no time to calculate or know from which angle and height the target will enter the airspace of the anti-aircraft artillery position, so Zhu Yuanhe cannot even calculate the shooting height.
But with computer assistance, all of this would be a piece of cake. All Mao Xiong has to do is input the coordinates of each anti-aircraft gun position into the computer as required, and the computer will do the rest automatically.
In other words, after using the artillery detection radar, all three minutes of the missile entering the range of the anti-aircraft gun will be fully utilized, and the interception time will be changed from the original one minute to three minutes. During these three minutes, an anti-aircraft gun will
Can fire 36 rounds of artillery shells.
36 rounds compared to the previous 12 rounds... Regardless of the accuracy, the number of shells fired is three times the original, which means that the probability of successful interception is tripled.
As soon as these words reached the Supreme Deputy Commander, the Supreme Deputy Commander immediately understood that this kind of radar does not command an anti-aircraft artillery position, but can command an anti-aircraft artillery defense system at the same time. It is actually a command and control center. In principle
Within its detection range, that is, a circle is drawn with it as the center and a radius of 30 kilometers, and all air defense systems within this circle can be commanded by it.
What the deputy supreme commander has to do is to use telephone lines and radios to connect each anti-aircraft artillery position to this radar, so that the data calculated by it can be sent to each anti-aircraft artillery position in a timely manner.
"This will make the air defense battle easier!" the Supreme Deputy Commander said loudly: "This is what we need. Tell Comrade Lemonlokov to find a way to buy it!"
After receiving the order, Lemonlokov said to Wang Xuexin helplessly: "You win, Comrade Commander! If the radar you mentioned does have the performance you said, then we will buy it!"
"Very good!" Wang Xuexin said: "But first, you need to provide the basic data of the 52K anti-aircraft gun, such as the muzzle velocity of the shell, the range, the weight of the warhead, wind resistance, etc. We need to use these data to calculate!"
"no problem!"
"In addition, we also need several 52K anti-aircraft guns and enough artillery shells!" Wang Xuexin added: "You know, we need to use this kind of gun for testing, and you also want to see its calculation results, right?"
"Of course!" replied Lemonlokov.
These requirements put forward by Wang Xuexin are normal.
In fact, it would be strange if these requirements were not mentioned... How could an air defense system developed based on the 52K anti-aircraft gun not need this anti-aircraft gun? Does that mean that any anti-aircraft gun with different muzzle velocities can use the same ones?
Yuanhe shoots high to intercept the target?
This is obviously wrong!
"Finally..." Wang Xuexin said: "Thirty million US dollars... you can transfer it to my account!"
As he said this, Wang Xuexin wrote down his bank account number on the manuscript paper and handed it over.
At this time, Lemon Lokov hesitated, and he said with some embarrassment: "Comrade leader, you know our situation. We are currently fighting Hans, and we are not financially well-off..."
It’s not that Mao Xiong cannot afford the money. Although thirty million U.S. dollars is not a small amount, it is nothing for a big country like Mao Xiong. (Mao Xiong’s GDP during World War II was about 43.3 billion U.S. dollars)
However, during the war, the Bear's budget was small but there were many areas where money needed to be spent. This did not allow him to spend money lavishly, so he had to be frugal in all aspects.
Wang Xuexin put on a troubled look: "Comrade Lemon Lokov, the price I gave you is already quite favorable. If this equipment is sold to Eagle Sauce or Sun Never Sets, I believe they will not have any arrears...
…”
"I know, Comrade Leader!" Lemon Lokov said: "We have another merciless request, that is, we hope you will not sell this radar to Yingjiang, Sun Bu Luo, or other buyers for the time being.
.I mean, can you try not to let others know?"
"This..." Wang Xuexin shook his head helplessly: "Comrade Lemon Lokov, you know our current situation. We also need foreign aid and equipment. On the one hand, you want to default on the payment, and on the other hand, you ask us not to use this
Sold this radar to others... What will happen to China? What will happen to the Eighth Route Army? What will happen to our war..."
"We will provide corresponding compensation!" Lemon Lokov quickly replied: "For example, what equipment you need, as long as we have it, we will try our best to provide it to you at cost price..."
This was what Wang Xuexin was waiting for, which was why he never mentioned the need for the Bear Artillery.
A rule of thumb in doing business is to never let the other person know how much you want something from him!
