That's what you want!

The second machine factory, always lagging behind the first machine factory, every time the leader goes to the grassland city to inspect, it must be to go to the first machine factory, and then to the second machine factory, and in recent years, the second machine factory is not doing nothing, they have finally found a lot of experience, found a lot of methods.

Just study Qin Zhenhua more!

Now, after some research, Xie Huimin has learned the experience.

This time, the self-propelled anti-tank gun should play the leading role! The 120 mm tank gun has been defeated, but at present, it is still the most powerful tank gun in China, and even more powerful than the current 125 mm tank gun!

After all, the 125 mm tank gun has just begun to be tested, and the charge does not dare to be too much, only reaching the penetration depth of 450 mm, which has completely satisfied Lao Ba, it can be seen that in terms of firepower, its own side has indeed been developed, and has come out of the shadow of the past.

In terms of chamber pressure, the 125 mm tank gun has only reached a stable chamber pressure of 470 megapascals, while its own 120 mm tank gun has stabilized at 560 megapascals, of course, as the 125 mm gun continues to dig deeper into the potential, it will definitely be able to increase to 560 megapascals, or even higher, to 600 megapascals, which should be no problem.

However, that's all for later, and for now, the 120-mm gun is already the most mature.

The armor-piercing ability reaches 500 mm, which is appropriate, but there is still room for improvement in this data!

Now, looking at everyone's surprised expressions, even Qin Zhenhua showed a look of surprise, Xie Huimin's heart at this time was also beautiful, okay, I saw it, this is the effect I want!

Xie Huimin is satisfied.

"Yes, in the past, we tested it up to 500 millimetres, but now, in order to continue to exploit its potential, we are using the latest materials."

"Is it depleted uranium?" Hearing Xie Huimin's words, Qin Zhenhua finally remembered this stubble.

On the road of tungsten alloy armor-piercing bullets in China, we have been tirelessly researching, anyway, the domestic tungsten ore is quite abundant, and we don't care about these consumptions, but the characteristics of tungsten alloy have always been incomparable with depleted uranium.

One of the characteristics of depleted uranium is that it is self-sharpening. In the process of armor piercing, the other bullet cores are getting more and more blunt, only depleted uranium, which is sharpened and sharpened!

So, if nothing else, as long as the material of the bullet core is replaced with depleted uranium, it can be improved by a large margin!

Moreover, this also solves the problem of nuclear waste, after all, nuclear reactors will produce a certain amount of nuclear waste, and how to deal with this waste has always been a problem, and it is of course better if it can be reused.

It's just that if you want to make depleted uranium alloy, it is not easy, just like tungsten alloy, the special process can make it hard and strong, and the current depleted uranium alloy, how to smelt, how to cast, is a problem.

It seems that it is our own material department that has made a breakthrough!

Domestic research on depleted uranium alloy also has a history, and after all these years of research, it has been obscure, and now, it seems that it is finally holding back a big move.

(Check the information, it is said that during the war of the stick country, the 85mm gun on the T-34 tank we used had depleted uranium shells?) also swore that it was on CCTV, but East China felt suspicious, the Soviet Union had just detonated the atomic bomb at that time, and they had the energy to get the depleted uranium bomb out? The Americans also came to maturity in the eighties, right? ）

"It's Special Alloy No. 4." Xie Huimin said, this title, after all, is a bit evasive.

"Okay, let's test it out." He Lao said: "Our army, firepower has been shouting for the king for so many years, and now, we can finally really be the king in firepower." ”

"Yes, test it once, but, Mr. He, this time we want to change the target." Xie Huimin said.

A change of target?

Hearing this, everyone was stunned again.

Okay, this time, the second machine factory has played enough tricks! Qin Zhenhua also sighed that he didn't prepare too much this time, and he didn't plan to steal the limelight of this self-propelled anti-tank gun, but Xie Huimin and they did this, which really made Qin Zhenhua feel a little impressed, and they would play like this!

"Now, gap armor is already in vogue." Xie Huimin said: "Our target, fixed, a group of 100 millimeters thick steel plates, and then half a meter apart behind, and then put a second piece, we have done a good job of this target, as long as it is fixed on our shooting range here, it will be fine." ”

The times are developing, technology is advancing, and the current armor is all composite armor, layer by layer, and now, when you shoot your own target, you have to do the same, layer by layer, between the two layers, with air as a barrier, which forms the lowest level of gap armor.

"Okay, approved." He Lao said.

This is not just a fraud, but an increase in difficulty, and of course He Lao is satisfied with this.

So, another car from the No. 2 Machine Factory drove to the position on the target side and began to set it up.

"Okay, Lao Xie, you will definitely play very well today." Qin Zhenhua said.

"Yes, of course it's beautiful, but if you go to the site and look at it from the side, it's even more spectacular." Xie Huimin said.

In the past, the target was a thick target, either worn or not, although the process of armor piercing was magnificent, but it was all inside and could not be seen, but now, you can finally see the process in the middle, it must be spectacular.

"Okay, that's easy." Qin Zhenhua said: "Drive our wheeled infantry fighting vehicle, stop from the side, and watch from nearby. Hey, can you make sure you aim? ”

With a penetration depth of five hundred and fifty millimeters, dozens of 551 armored vehicles can be strung with sugar gourds side by side, so now Qin Zhenhua has to say it in advance, in case of a mistake, the consequences will be terrible.

"You're still a hundred meters away, upwind." Xie Huimin said.

The accuracy of a 120 mm tank gun is quite high, and if it is a thousand meters, the error is not more than 0.26 meters X 0.26 meters, but if you drive a wheeled infantry fighting vehicle over, there will definitely be various leaders inside, so in order to avoid accidental hits, it is more appropriate to be 100 meters away.

As for Qin Zhenhua's proposal to drive a wheeled infantry fighting vehicle, Xie Huimin can also know why. So, he also reminded that the upper hand position!

"Well, we still have to turn on the overpressure three-proof system." Qin Zhenhua said, opening the back door of his wheeled infantry fighting vehicle: "Leaders, who wants to go over and see it in person?" ”
