"Don't we use the latest composite armor? We have high defense and enemy can easily kill our tanks?" Zheng Yucheng widened his eyes and asked www..lā

For a moment, Xie Kai and Qin Jinyuan looked at each other and smiled bitterly. How did they answer?

Who knows what the answer is to attack his shield with his spear?

"Okay, the Iraqis are waiting. What's more, they will have to test the gun before they know. The gun was dragged out like this and went to the gun field to shoot the target. How thick can our gun penetrate the homogeneous armor and how thick can the composite armor can penetrate, there will be a conclusion there." Xie Kai sighed.

No matter how ugly a cannon is, it is impossible to install a tank turret during the test firing.

Especially the bases below are all fixed.

I'm afraid that this thing can withstand it, so don't be too recoilable and the base can't bear it.

The Iraqis were waiting to see the test firing of the sample gun, but there was no other preparation. They just dragged the sample gun into the gun yard for test firing.

The base's composite armor model has been developed for a lot of time. Various experiments and theoretical analysis have been conducted these days. Which composite armor has higher defense power, and there is no test.

What is the penetration power of the 105mm rifled gun at the same distance? The high-explosive bombs, armor-piercing bombs, armor-piercing bombs, full-charge anti-destruction blasting grenades and reduce-loading anti-destruction blasting grenades, etc., must be tested to determine.

According to the previous plan, once a live-fire test is carried out, it will continue.

So far, a total of 5 sample guns have been delivered at the 541 tank base. Each sample gun must be fired according to the experimental plan until the barrel is scrapped.

Each shell must measure the initial velocity of the bore, the chamber pressure under different states of charge, and the barrel's ability to withstand the chamber pressure under different states.

After obtaining these data, special improvements are made. Specifically, whether the materials are further improved, the processing technology needs to be improved, or the internal processing accuracy of the barrel needs to be analyzed.

The 125mm tank gun was produced, and five sample guns were not fired yet.

Even the original 120mm tank gun of the z-122 tank project ended up only testing more than 100 guns.

At the beginning, the test injection was forced to end due to material problems, processing technology problems, etc.

Now no one can guarantee that new tank gun steel, body tube self-tightening technology, electroslag remelting technology and other new cast gun technology are adopted, and even the chrome plating technology and processing technology inside the gun barrel are introduced.

No one can guarantee what level it can reach.

"Does it take you a long time to prepare?" The Iraqis were a little dissatisfied with Zheng Yucheng and Xie Kai alone communicating with the artillery experts of the 359 project.

They were worried that the 404 people would cheat them.

"General, we have been conducting extreme environmental tests before. The combat performance of a tank is the most important thing about the attack ability of the tank gun! The best defense is attack. No matter how thick the defensive armor is, it does not have strong attack power, it will eventually be besieged and destroyed by a bunch of tanks with lagging performance. Didn't Germany make the terrifying Tiger tanks and Tiger King tanks in the same time be surrounded and annihilated by the Soviet T34 tanks?" Xie Kai asked Isad, who questioned.

The Iraqis knew about Soviet weapons and equipment.

The Soviet Union's military construction ideas even influenced Iraq. Otherwise, Saddam would not have ordered more than 2,000 Type 69 main battle tanks from China.

Quantity is far better than quality.

The Soviet army was able to defeat the German army that had overwhelmed the entire Europe by number.

Whether it is the number of troops or the number of weapons and equipment.

"That's true." Isad had to admit.

"We don't need to prepare. Whether it is the shells used for firing experiments or the homogeneous armor used to test penetration, they are all ready. Not only do we need to test the tank guns, but we also need to test the defense capabilities of the composite armor!" Qin Jinyuan said to the Iraqis.

He comes from Base 541, not the staff originally found in 404.

The Iraqis did not comment, and there was nothing worth arguing about this matter.

If the Chinese want them to see their attack power and defense power, they naturally need to conduct experiments.

"Just drag the tank gun to the shooting range like this?" Seeing the Chinese install a flatbed cart directly under the tank gun, the Iraqis were a little confused, "Don't they need to install it on the tank for experiments?"

"General, there is no suitable tank in our country that can withstand the recoil of the 125mm tank gun firing full-charge shells! The 359 tank uses new technologies and new materials to solve the recoil problem." Xie Kai explained.

In theory, there is no problem with tank guns.

All five sample guns were pulled out for experiments.

Some guns have muzzle retractors installed, while others are not installed.

"There are few countries' tank guns equipped with muzzle retractors?" Harry Mosan asked Xie Kai. He clearly saw that two guns installed with muzzle retractors. "Although muzzle retractors can absorb a large part of the recoil, it will also cause many difficulties, affecting the shooting accuracy..."

"This is indeed the case, and it will even affect the separation of the armour-piercing projectile and the support..." Qin Jinyuan nodded, "Our current cannon has not yet been finalized, and it needs to be conducted to conduct experiments and obtain various parameters!"

In order to obtain more parameters, each gun has almost some subtle differences.

During the previous extreme temperature experiment, a large amount of data was obtained. These data were subtle differences in the modification of the 125mm tank gun, especially the aluminum alloy air interlayer thermal sheath installed in the middle of the barrel, and the technology used on almost advanced tanks. The 541 helped the 125mm tank gun produced at the 404 base can be seen on it.

When Xie Kai first started this project, he convinced Mr. Zhu Yusheng to receive technical support from the domestic third-generation tank project. The technology of these artillery also paved the way for the domestic third-generation tank project.

Five cannons were transported by Jiefang Automobile and pulled to the cannon field that was originally used for weapon testing.

On the way out, I encountered a construction site where the airport was being built. Dozens of military excavators with 59 chassis leveled a large area of ​​the originally not-so-flat valley floor.

"Aren't these military excavators delivered to the hydropower troops and Iraqis?" Xie Kai looked at the dozens of excavators busy on the construction site and asked Zheng Yucheng in confusion.

"Our infrastructure for the Armed Police Hydropower Force is handed over to them for construction. At the same time, their personnel are training on our side..." Wang Guilin explained.

Xie Kai rarely pays attention to these things.

The airport construction has been underway for so long, but he hasn't come here to see it, and there is nothing to see. It's bare everywhere.

When Wang Guilin talked about training, a hint of inspiration suddenly flashed in Xie Kai's mind. He wanted to catch it, but he couldn't catch it at all.

"What are you thinking? Such cooperation is beneficial to both of us. After all, the performance of our excavator currently requires a lot of use to draw a conclusion." Wang Guilin thought Xie Kai was worried that the relationship with the customer would be affected.

The construction of the airport at 404 is all contracted.

The engineering regiment inside the base had already been evacuated as early as the evacuation of various projects.

"This is pretty good. If you have any problems, you can discover them during the use process." Xie Kai nodded and said.

He didn't say anything else, but considered the test firing of the 125mm tank gun.

For Xie Kai, the effect achieved by this gun test firing seriously affected the progress of the entire tank project.

Any tank is often evaluated from firepower, defense capabilities, maneuverability and the technology used above.

Test firing means whether the tank gun can be finalized. Once the theoretical design data cannot be achieved, these five sample guns will be just test items and need to be improved.

This will seriously affect the progress of the entire project.

"Are you worried about the experimental data of the tank gun?" Zheng Yucheng saw Xie Kai looking at the tank gun sample gun dragged by Jiefang Automobile in front and asked in a low voice.

Xie Kai nodded.

"Don't worry, there is no problem. From the beginning, our design used supercomputers to perform finite element analysis. So far, all experimental parameters exceeded theoretical data." Qin Jinyuan comforted Xie Kai.

He himself was equally nervous.

In the 541 base, they had already become idle because the 541 base had fewer projects after the military and civilian control were transferred to the civilian level. With the 541 tank gun business, the entire 541 base artillery research team became busy again.

The plan is based on the design provided by the 404, and a lot of analysis was carried out at the same time. All the tank gun-related technologies that have just been introduced abroad have been used.

"The attack ability of tank guns is not just guns, but also shells." Xie Kai said quietly.

Iraqis participated in the entire experiment.

When the tank guns were transported to the test range, the shooting experiment was not carried out directly, but instead, the tank guns were lifted to specially prepared positions for installation.

The 125mm tank gun generates a huge recoil when firing, if it is not fixed properly, the entire gun will jump up.

"The artillery is a brand new sample, and the shells are also newly produced!" Xie Kai was not worried, it was fake.

There is no similar artillery in China. The shells of tank guns are all urgently developed by the technical teams of 541 and 404. Of course, the main source of technology is the 105mm rifled gun ammunition related technology sold to China by the British.

The installation work was going very quickly, and several types of shells were placed not far behind the tank guns, from two to four kilometers, with different types of targets placed, and more were homogeneous armor of different thicknesses.

Most of these targets have been installed before.
