Chapter 932: Every time I get fooled, it’s different

The eyes of the army comrades lit up. Gao Zhendong knew his comrades too well. This parameter had a fatal appeal to them.

A 7.5kg machine gun that can fire full-power bullets and can also be used as a heavy machine gun. For them, just give it a try and they will naturally bite the hook. If you don't let them bite, they will definitely be angry with you.

If the technical source of 9kg needs to be considered, then 7.5kg compared to the 11kg of the current light and heavy dual-purpose machine guns can suppress all dissatisfaction.

The Defense Working Committee was obviously aware of the situation. Gao Zhendong's final blow, which made things even better, completely suppressed all opinions. No one could object anymore. Do you have the guts to do the same?

"Okay! Let's do this! We'll go find the Russians to buy samples later. This task will be handed over to you, Beijing University of Technology. As for the light and heavy dual-use... continue to work on it, make some and compare them, and it will also be good for technical reserves."

For things that have already been developed, whether they can be cancelled at will or not also depends on the feelings of various parties. It is also a good thing to reserve more technology. Now the conditions are much better, and it is not a big problem to support the development of one more machine gun.

Gao Zhendong only needs to take out the good goods, but the Defense Work Committee has a lot of things to consider.

As a professor of Beijing University of Technology, Gao Zhendong represents Beijing University of Technology here, so it is "your Beijing University of Technology". Moreover, saying this makes it feel like Gao Zhendong is a member of the Defense Working Committee, which is really cool.

During the whole process, no one doubted whether the improved 7.5 general purpose machine could be made. It seemed that as long as Gao Zhendong said so, it was a done deal, and it was just a matter of choosing whether to do it or not.

"Comrade Zhendong, the matter of the heavy machine gun being lowered to the ground that you mentioned..." The comrade from the army brought up the matter cheerfully.

See what other surprises there are?
"Yes, that's what I was going to say. We all know that with the development of precision-guided munitions and the improvement of air tactics, high-altitude air defense is no longer very reliable."

Gao Zhendong's words reminded his comrades of the aerial strikes in recent operations. At that distance, the anti-aircraft machine guns, which were originally used to defend against dive bombing and ground strafing, were really useless.

Think about the heavy armor on the key parts of the new Gong-5 bomber we modified. It seems that this thing really has a very low cost-effectiveness.

"But with the rise of helicopters, anti-aircraft machine guns still have some role to play, right?" The comrades also did not neglect the study of modern warfare.

"Yes, but firstly, we have portable anti-aircraft missiles. Secondly, the main function is to attack the ground, which does not mean that it cannot attack the air. If the tripod is properly designed, it can still retain the anti-aircraft capability. There is no substantial difference. On the contrary, it is more flexible to use."

Portable anti-aircraft missiles... Thinking of Zang San’s helicopter, the comrades were happy.

And Chief Engineer Gao is right. It is mainly used for ground attack. This is a change in the usage concept, but it does not mean that it cannot be used for air attack. When it is time to attack the air, you can still set it up and shoot fiercely, and the caliber of 12.7mm will not change.

"Well, that makes sense. But the 12.7mm anti-aircraft machine gun is so heavy. Even if it is reduced to 50-60 kg, it is actually very difficult to accompany. Now the 40 kg 7.62 heavy machine gun is already difficult to carry."

"Yes, no matter how much you lose weight, you have to lose 50 kilograms, right?"

"With such a large caliber, it's too light to guarantee accuracy, and it bounces for a long time after firing."

It is not easy to deal with this matter. We need to consider issues such as weight, ease of disassembly and assembly, length and volume.

At this time, the comrades saw that Gao Zhendong had a strange expression on his face, as if he wanted to laugh, and they didn't know what was going on in his mind.

Gao Zhendong certainly did not want to laugh at these comrades, but he was thinking of the bad tricks we fell into decades later. We were fooled every time, but each time was different.

NSV机枪的“总重”25公斤、AIM-120导弹的双脉冲发动机、高超音速导弹的高速机动再入、F-22战斗机的2.0升力系数、朱姆沃尔特的双波段天顶星雷达、NGAD的wiki试飞……甚至传言F-119发动机的推比10也加入了这个行列，真是没地儿说理去。

Except for NSV which was caused by our own translation error, all the others were just the enemy bragging. This is very difficult to accept. These foreign devils are so bad!

But it is hard to say whether it is good or bad. Sometimes when the ability is strong enough, it is hard to say who will suffer the loss.

Gao Zhendong really wants to laugh when he thinks of his predecessors who felt regretful in the 80s because they had no choice but to control the total weight of the 12.7mm heavy machine gun to 26.5 kg.

Oh, that’s not right. It’s the 60s now and I’m the senior. Stop laughing. That’s so unkind.

Seeing Gao Zhendong so happy, the comrades lost their composure. They said, "You, even if you are so capable, you can't laugh like that, right?"

Just when the comrades were becoming increasingly upset, Gao Zhendong calmed everything down with just one sentence.

"If I say that I can control the weight of the gun to 32 kilograms, can I accompany it?"

The whole place was silent and you could hear a pin drop.

How much? Either I'm deaf or you're crazy!
This is what all comrades think.

Many people knew that he was working on materials, but no matter what material it was, the main body of the gun was made of steel, and this could not be changed. As long as it was steel, the density would not be lower than 7.8, and no matter how much you messed with it, it would not change. "Comrade Zhendong, did you... did you say something wrong?" Even the comrades in the army were not calm. This was impossible, and they quickly found a way for Gao Zhendong to save face.

Gao Zhendong had a smile on his face, but his tone was firm and his words were clear.

"Yes, that's 32 kilograms."

Our first generation of heavy machines weighed 88 kg, the second generation weighed 56 kg, the third generation weighed 41.5 kg, and the fourth generation, which was the generation that was deceived, weighed 26.5 kg. The fifth generation increased a little, but there is no essential difference.

Gao Zhendong still didn't want to try something so extreme. After all, 32 kilograms was more than enough and a number that could shock everyone.

He knew the principle and structure of the machine gun, but some details were still unclear to him, so he added 26.5% to the weight of 20 kilograms, to 32 kilograms.

"The gun body is estimated to weigh 18 kilograms, and the gun frame is 14 kilograms. Empty gun, I mean empty gun." Gao Zhendong further clarified the parameters. Compared with 17 and 9.5, they have all increased a bit, especially the gun frame.

Nonsense, of course we know you are talking about an empty gun. If you can still control the weight under 60 kilograms with 32 rounds of bullets, then you are a god.

Fourth-generation heavy machine gun: This matter is actually not beyond discussion.

"Impossible. If the 12.7 is reduced to 18 kilograms, it will fall apart with one shot!"

Gao Zhendong was cheerful and not angry. In fact, these comrades did not stand up and say he was talking nonsense, which was considered that these comrades had good self-cultivation. There were some things that he knew but others did not know: "I am a materials scientist. The new materials I need are not a big problem for me. With some optimization of structure and principle, there is no problem, no problem."

Oh, this guy is good at materials, which is his innate advantage. If you think about it this way, it doesn’t seem impossible that the gun body weighs 18 kilograms. Think about the armor and body of the second-generation tank that is about to be finalized...

It is a good thing that the comrades in the army surrendered immediately on this issue. They should surrender quickly.

That's really surrender. As soon as the thought comes to my mind, I suddenly feel the world is wide. I won't say anything more. Just wait.

32 kilograms, oh my, this is to move 12.7mm to the front-line position, and laugh at the light infantry in the world, who dares to shoot at me.

The comrades in the army who had received countless benefits from Gao Zhendong no longer questioned this matter. They just had to wait.

"Well, that does make some sense, but the gun mount is so light that it will probably be deformed by a single shot." Yes, yes, you are amazing at working with materials.

"The same, the material is strong enough and the structure is optimized enough, it won't change." Gao Zhendong is still the same.

Oh shit, could you please stop talking about materials?

"But the gun frame is too light, so dispersion becomes a problem when shooting, and this can never be changed."

A comrade who deals with firearms has hit the nail on the head. This is the biggest problem.

In fact, the dispersion of the fourth-generation heavy machine can only be said to be adequate, but not outstanding.

But heavy machine guns are not actually designed to be very accurate. Different weapons have different uses. The biggest reason why Gao Zhendong is not worried is that by the fifth generation, the weight has not been increased much. Moreover, the fourth generation of heavy machine guns and its derivative models have been used for a long time. If the accuracy was not enough, it would have been changed long ago with the capabilities at that time.

"Don't worry about that. We have the technology to control the dispersion within the usable range at this weight. Besides, this thing needs a certain amount of natural dispersion. Just ask the comrades in the army and they will tell you."

Heavy machine guns, a weapon used for long-range suppression shooting, actually need to strike a small area centered on a certain point. And within their range, relying on manual control to actively create dispersion is actually not very effective. The dispersion created by the gun's own shaking is, to some extent, more effective.

In an area, dozens of 12.7mm rounds fell left and right. Who dared to rush forward? Who dared to show up? The purpose of suppression is not mainly to kill, but to delay the enemy's actions, prevent the enemy from deploying or laying equipment, and suppress the enemy's firepower.

Is there technical control? Gao Zhendong said this in a mysterious way, without any details, but other comrades could not help but take it to heart. He dared to say so, and even said it under such an outrageous parameter condition, which means he really has it all planned out.

Under normal circumstances, people would never brag to such an extreme. For example, today he said that if he could reduce it to 45, it would be excellent, and reducing it to 40 would be the limit of ordinary people's bragging.

32? Maybe they really have something.

"Is it really necessary to spread this?" Some comrades were still a little puzzled.

Speaking of this, the comrades in the army were no longer sleepy: "Yes, yes, yes, Comrade Zhendong is right, this is indeed necessary, he knows the business."
