And that's just an engine.

And that's not counting the two-way stabilization system of a tank gun, a fire control system and a host of things.

The most important thing is that a lot of the technology of the third generation tank is built on the computer! This is counting on Cao Zhijiang to get the computer done as soon as possible, and then quickly upgrade, the current computer is a bit poor for the advanced tank fire control system with relatively high requirements and fast calculation speed.

"You have a blueprint for a tank?" Li Rui put the lunch box on the stool next to Liu Yijiu, which was occupied by Liu Yijiu's drawings everywhere, and there was not much spare space at all.

"Don't touch those drawings of mine!" Liu Yijiu didn't reply, so he said to Li Rui.

"You're so messy here, like a kennel, you don't know how to clean it up! You stinky men are like this, you don't like to clean ......up" Li Rui ignored Liu Yijiu's words, inside this room, it looks really messy!

Many women have an obsessive-compulsive disorder for the environment.

"I told you, tell you not to touch any of the pieces of paper I have here, get out!" Liu Yijiu saw Li Rui holding a lot of his own information in his hand, and he was immediately furious.

"Get out, get out, who do you think wants to help you clean up your kennel! I just don't know what to do! Li Rui saw that Liu Yijiu's face was distorted, and he didn't dig his ancestral grave, so he was immediately aggrieved, so he directly threw the information in his hand on the bed, and then ran outside with red eyes.

Liu Yijiu didn't care about this matter at all.

He was used to keeping his design manuscripts at hand, and he was able to memorize them.

As long as it is disturbed by others, it is not easy to find these materials. It can become a hassle when you need it.

In the base of the Nine Courtyards, the few apprentices who followed him were all aware of his situation. Sometimes, when the drawings need to be redrawn by several other people, they will also take them and put them somewhere. Otherwise, Liu Yijiu would be very angry.

"What are you doing here? I hear your roar from afar. Who has offended you again? Zheng Hao and Wang Shunyi walked in from the door, and as soon as they saw that there were drawings everywhere on the ground, Wang Shunyi picked one up, and then was immediately attracted by the drawings, and kept picking up other drawings on the ground...... "This is the design drawing of the new tank?" Xiao Liu, you kid is getting more and more powerful, and you want to finish the tank alone? If you do this, what else can the people of the whole system do? ”

"Well, don't I have nothing to do these days? Director Zheng didn't say that our base is ready to start the tank improvement program. I don't think the base has started yet, and I have talked a lot about some ideas about tanks with the Americans during this time, and I have a lot of ideas, so I just took advantage of this time to get the concept map out, and the projects we need to tackle are listed one by one......," Liu Yijiu explained with a depressed face.

"By the way, Director Zheng, how is the situation at Factory 2983?" Liu Yijiu thought that Zheng Hao had been on the side of Factory 2983, which was a gun factory he had hoped for.

There are quite a few factories in the Republic that can produce heavy artillery, but only they belong to their own Ninth Academy. It's the best, at least, it's easier to coordinate various problems and produce research.

"The new 82mm mortar you designed is currently being produced. Trials are underway, and the results are very good. Tian Deming: They are now preparing to improve the 63 type 60 force, and they hope to be able to listen to your expert opinion. Meantime. They also hope to be able to shift their production capacity to research on 122mm howitzers......" Zheng Hao said with a smile on his face.

"That's what you think, right?" Liu Yijiu said with a frown.

Didn't he just mention such a sentence casually at the beginning, Zheng Hao actually began to encourage them to make heavy artillery?

"I can't say it's my idea. It's just that I mentioned it casually. An artillery factory, which can only produce mortars. It doesn't mean much, does it? It's still interesting to produce real cannons. Besides, didn't you also say that if we want to build tanks, we must first have artillery? Lao Maozi's tanks all use 125 smoothbore guns. Why don't we have to get a 152 or 155 one, in this way, the cannon is larger than their caliber, just like they used the T72 to abuse our 59 small tank, one shell, at that time, they were really killed with one shot......" Zheng Hao's face was full of deterrence.

Liu Yijiu was frightened by the brain hole he opened.

155 tanks on 59 guns? With a small body like 59, this must not be overturned by the huge recoil that makes people collapse?

In other words, it was impossible to shoot a few shots, and as a result, the entire tank was scrapped.

"What's wrong? Is there something wrong with that? Isn't the bigger the caliber of the cannon, the better! There is no need to change other places, just add this gun to our tank, and when the time comes, the armor will be thickened a little, and the starting hit rate will be improved, and Lao Maozi will be dumbfounded when he sees it...... "Zheng Hao was stunned when he saw Liu Yijiu's idea put forward, and he immediately felt a sense of accomplishment.

"Director Zheng, have you ever considered how much recoil such a big cannon will have?" Liu Yijiu sighed.

It's terrible for people who don't know how to engage in technology.

"What's wrong with that? Lao Maozi can get the 125 cannon, and our one is only 30 centimeters larger than theirs. Let's figure out their skills and improve them......" Zheng Hao said indifferently. "We don't lack funds, what are we afraid of? Let me tell you, a lot of heavy artillery on the front line also has a lot of quality problems, and many of them have to be replaced......"

In the final analysis, Zheng Hao is still for his political future.

The heads of the republic liked the cannon far more than anything else.

With the 152 or 155 heavy gun, when the time comes, get it on the tank, get it behind the butt of the car, and then, it will directly become a self-propelled howitzer, which is more powerful than the Type 66 152mm howitzer cannon currently used in the Republic, and then the logistics department will have to have a chair to accommodate his ass, right?

Liu Yijiu looked at Wang Shunyi, but got a wry smile and shrugged.

"Don't look at me, it's his idea, he's been instilling in me this stuff since I met him, hoping to get support. I don't know anything about artillery...... "Wang Shunyi directly put aside the relationship between this matter and himself.

Liu Yijiu was petrified in an instant.

The matter of feelings is really Zheng Hao's brain.

Now that they have the two most advanced tanks in their hands, he feels that it is relatively easy to achieve them technically.

For those who don't know how to do it, these seem to be no problem, just put the barrel on the turret, and then install the turret on the chassis of the tank, and you're done.

They simply didn't take into account that it wasn't that easy at all.

Not to mention now, even if you wait another thirty years, there is no country that has put 155 guns on tanks. Most of them are calibers like 122 or 125.

It is because the larger the caliber, the greater the recoil generated when the gun is discharged. Even those 10,000-ton battleships, the final caliber of the main gun is only five or six hundred millimeters! Is it possible to build a tank on land as large as a hundred tons?

How powerful an engine would it take to get these steel fortresses moving?

"Director Zheng, this is not as easy as you think. If we really want to get such a gun on the tank, not to mention anything else, the little money we have on hand is not enough at all......" Liu Yijiu explained to Zheng Hao how difficult it is to put the tank on the 155 gun, and at the same time, he also said all the technical problems encountered in changing the 59 tank.

This was like a basin of cold water splashed on Zheng Hao's head, and the whole person immediately fell down.

"So, this project is scrapped?"

"We can't say that, we can get self-propelled grenade cannons......" Liu Yijiu said comforting Zheng Hao.

In any case, it is impossible for the Republic to give up research in this area of artillery.

There are too many projects to be done, and we must be able to get the maximum harvest with the least investment, so that the republic can stand up in the future situation!

"Okay, let's go back and discuss these technical issues with everyone, at present, the superiors have summoned us all to love this, mainly for the issue of our autonomy, this was raised by Xiao Liu at the beginning, you have also explained to several leaders, they are not very confident in this, if we really get autonomy, a large part of the project is impossible to get the above appropriations......" Wang Shunyi did not want to talk more about this topic.

He was more interested in getting missiles.

Moreover, the bigger the better, and it is best to be able to make a missile that can hit any corner of the world, and this is the goal that national defense science and technology workers should set.

People like Zheng Hao are too short-sighted.

"There's nothing to discuss about this, we'll have to get the tank. There has been no progress from 69 to now, whether it is 541 or 617, their level is like that...... "Zheng Hao didn't dare to take on the topic of self-funding.

They made a lot of money some time ago, but this money can't support some large-scale projects at all.

"Tanks and helicopters have to be built, and only with the cooperation of these two things can we exert greater combat effectiveness. In terms of self-funding, I don't think there's a problem. After all, the third district has been tested, and now many of our businesses are like this. At the same time, many products in the domestic market can be very profitable, because our people are basically all in the four walls, not that they don't want to buy things, but they can't buy ......what they want," Liu Yijiu said through gritted teeth.

It is not easy to convince these two people.

It seems that they had been in contact with the people above before coming to find them. (To be continued......)
