The 125mm tank gun, the material belongs to the new gun steel material used in the Type 99 tank gun provided by Xie Kai, and the production process adopts electroslag remelting technology to make the material purer and better strength;

The technology that can be used is basically used.

This is a 125mm tank gun!

And Xie Kai deliberately wanted to sell it to the Iraqis, that is, he went to the M1 tank of the US army, and even if this thing did not use depleted uranium armor, the thickness of the armor exceeded 600 mm of homogeneous armor! If the reactive armor is hung up, the armor thickness is thicker, and with the armor-piercing ability of the current tank gun, it will not be able to impress the main armor of the M1 tank at all.

"Iraqis and Iranians don't think so! As long as they approve and have money, they can study further. Then it won't be a problem!" Wang Guilin said, pointing to the smiling Iraqis and the Iranians.

The two sides are enemies, but at this time, they can live in peace.

For the sake of the tank in front of you.

Xie Kai looked at Wang Guilin and sighed in his heart.

Where do they know what is in their hearts?

The Type 69 tank, in the face of advanced third-generation tanks and aerial bombardment, is completely at the level of cannon fodder.

In the Gulf War, weapons and equipment that performed well will have an extremely huge market.

The M1 performed well in the Gulf War, and the local tyrant Saudi Arabia and Kuwait purchased 315 and 218 M1A2 tanks from the United States respectively. As long as the 359 tank overturns the M1, even if there are only a few, the order will make the 404 happy.

Wang Guilin and others, how did they know that Xie Kai thought so far?

"As long as they're willing to pay for it. At present, how far we can reach can only depend on technological breakthroughs. Zheng Yucheng is also very satisfied with this effect.

Compared with domestic tank guns, the 125mm smoothbore gun jointly developed by 404 and 541 can be said to have given them a surprise.

"Our tank guns have surpassed all tank guns in China. It is very likely that we can all win the third-generation tank gun project of Mr. Zhu!" Qin Jinyuan was also very satisfied with this test firing.

Armor-piercing capacity exceeds their expectations.

After all, there's a lot that could be improved.

Xie Kai looked at Qin Jinyuan and smiled bitterly, he couldn't say anything.

He couldn't tell the other party that I was not stronger than the domestic tank gun, but worried about how such armor-piercing ability would overturn the M1 tank of the US imperialists, right?

"The initial velocity of the muzzle has reached 1650 meters per second, and the material of our armor-piercing shell is not good, if the material is replaced, the armor-piercing ability should be stronger!"

Xie Kai nodded, "Ordinary alloy materials, basically, are like this, either make a fuss about the armor-piercing projectile material, or make a fuss about the armor-piercing projectile design. ”

Depleted uranium alloy, Xie Kai doesn't know anything about this thing.

Even if you've been exposed to it, it's good to know some of the features.

It's a pity that he really doesn't know anything about the production of depleted uranium alloys, let alone the armor bombs made from depleted uranium alloys.

"The current design is already the most optimized design, and there are too many things that cannot be modified in the short term, and the only thing that can be found is the material. Qin Jinyuan shook his head and smiled bitterly.

"Do we have depleted uranium alloy in China?" Xie Kai finally asked the question.

"What is depleted uranium alloy?" Not to mention Qin Jinyuan, even Wang Guilin and others didn't know.

Xie Kai was helpless and asked in vain.

"I don't remember who I heard say, it seems that the Americans have developed a new type of armor-piercing projectile, and the material is the material left after refining enriched uranium, I think, our domestic nuclear industry research system should have such good research......" Xie Kai is also not clear, when exactly did the country come up with depleted uranium alloy.

I've just heard of this thing.

The Americans advertise this alloy, this kind of thing has less radiation...... Xie Kai absolutely does not believe in the propaganda of the Americans.

If that were the case, the battlefields in Iraq and Kosovo would have been dropped by the US imperialists with an unknown amount of depleted uranium shells, resulting in a tenfold increase in cancer mortality rates in these two regions compared to before the war, and children were more affected, with all kinds of deformities abounding.

Even veterans of two wars in the United States ended up suffering from disease and cancer.

Even so, the Americans have not abandoned the use of depleted uranium shells.

There is no greater shamelessness in the whole world than theirs.

China may be studying this thing, whether it is equipped with troops, Xie Kai must not know.

"That kind of material is good?" Qin Jinyuan asked.

"Perhaps, I forgot whether I saw it in a magazine or heard someone say it, it seems that the material after refining U235, which is based on U238 as the theme, is very dense...... "Xie Kai knows this thing, there are really not many."

He once saw two theories, one is that depleted uranium armor is dense and hard.

The density in front is large, Xie Kai knows that after all, the periodic table of chemical elements is there.

As for the high hardness, some people say that the hardness of this substance is not high at all, and it is even very soft, anyway, Xie Kai has never seen this thing, and he doesn't understand the characteristics of this thing.

Even if he had this thing in front of him, he wouldn't touch it.

Radiation!

The Americans are deceiving the whole world when they say that the radiation is small and will not cause harm to the human body.

"I'll ask then, and if there is, maybe we can try to make armor-piercing bullets. Wang Guilin looked at Xie Kai and didn't understand whether he really didn't know or whether he was fake.

"This kind of thing, isn't it supposed to be very soft, but uranium is very easy to oxidize, high-speed flight speed, air and uranium friction is too strong, it will cause combustion, and the high temperature generated during the impact will soften the armor ......strength of the bullet impact point," Zheng Yucheng suddenly spoke.

Several people looked at Zheng Yucheng in surprise.

Especially Xie Kai, who was even more surprised.

Does Zheng Yucheng know the properties of uranium?

This old guy has been engaged in nuclear research before? I haven't heard of it, hasn't he always been a manager?

"Why are you looking at me like this? Our base is powered by a nuclear power plant! Before, the Second Machine Department had a research team on our side. Zheng Yucheng was a little embarrassed by several people.

"It has nothing to do with you. Xie Kai questioned Zheng Yucheng.

The old guy shouldn't be that simple.

"You kid knows about depleted uranium alloy, it should be seen in some information on our base. In the 70s, the team of the Second Machine Department in the base was researching this thing, mainly to make depleted uranium bombs......" Zheng Yucheng's words made Xie Kai even more disbelievable.

Wang Guilin is in charge of the logistics of the base, and he doesn't know that Zheng Yucheng is completely casually pinching.

"Really?" Xie Kai didn't ask Zheng Yucheng, but Wang Guilin.

"It seems that at that time, we were only responsible for logistics, and it was not clear what projects they were working on!" Wang Guilin looked confused.

"That thing is not depleted uranium, but pure uranium, and the uranium-238 left after refining uranium-235......" Zheng Yucheng said triumphantly.

The base did have project teams from various ministries of industry back then, and if anyone knew best, it was definitely only Zheng Yucheng.

He is the top person in charge of the base, and it is impossible for him not to know what the various project teams are responsible for researching.

"Is there any result?" Xie Kai cared about whether there was any result.

With results, it is possible to engage in depleted uranium shells.

Sold to the Iraqis, specifically to clean up the US imperialists.

Forget about the Iranians, anyway, they and US imperialism will not be able to do anything in the next few decades.

"I don't know, I'll have to ask over there. There was nothing to be done on our side at the beginning......" Zheng Yucheng's words made Xie Kai roll his eyes, "That thing really works?"

"Don't you know all the properties of depleted uranium alloys, and ask me if it's useful?" Xie Kai was speechless.

He didn't say anything, Zheng Yucheng told him that the project team of the Second Machine Department in the base was originally engaged in this, but he didn't know if there was something.

"I just knew, and they just told me the theory. Zheng Yucheng was very aggrieved.

Xie Kai has never known whether there is equipment for depleted uranium armor-piercing shells in China, according to his opinion, it is impossible to equip this thing in China, there is research in this area, even if it is finally researched, it is estimated that it will only be an experiment, not equipped.

The combat mission of the PLA is territorial defense, the scope of operations is on the borders of the republic, defending against enemy invasion.

Instead of fanning the flames and bullying people everywhere in the world like US imperialism, anyway, fighting a war on someone else's territory, no matter how serious the environmental damage is, it is no longer suitable for human existence, it has nothing to do with US imperialism, right?

Even if he is blamed by the whole world, the president of the United States can pat his chest and say that it was the previous president who did it, and the responsibility of the previous administration has nothing to do with us.

"This thing, can it really make armor-piercing bullets, does it have such strong performance?" Qin Jinyuan never spoke.

Being able to have stronger armor-piercing ability is the pursuit of every tank gun designer.

"Yes, at the same distance, the armor-piercing ability should be stronger than tungsten alloy. Tungsten alloy armor-piercing bullets are self-blunting, no matter how sharp they are at the beginning, they will continue to be passivated during the armor-piercing process, and even shatter because they are too hard and lack toughness...... Depleted uranium alloys are different, because of the characteristics of the material, they are constantly sharpening themselves in the process ......of armor piercing," Zheng Yucheng spoke again.

Xie Kai's eyes lit up when he heard the old guy's introduction.

It's a shame that the old guy said he didn't know.

There are definitely yes, and experiments have been done, otherwise he would not have known this property of depleted uranium alloys.

"Don't look at me like that. This thing has a lot of radiation, and it is not harmful to the environment, and when it was first studied, depleted uranium was too soft to be used to make depleted uranium bombs......" Zheng Yucheng finally told the truth.

The project team of the second machine department of the base has studied this thing and achieved certain results, but it has not yet reached the practical stage.

"Lao Zheng, you ask this thing over there, if there is, use this to produce armor-piercing shells for experiments, and if the effect is good, provide it to the Iraqis!" Xie Kai said as he licked his lips.

When the time comes, let the US imperialists cry themselves.
