"Tell me about it?" Wang Hao asked Xie Kai tentatively.

He is more interested in the modularity that Xie Kai said, especially the design of the basic model by replacing the main weapon and other devices to form a complete series of infantry fighting vehicles that can cope with any form of task.

At this moment, he didn't care about the contradiction between Xie Kai and him.

As Xie Kai said, there was no big deal of contradiction between the two.

Even, it can be said that they have been fighting since childhood, and all kinds of fights are because the base is boring.

"The modular design, just like the blocks we play with in kindergarten, everything is standard. When designing, we will solve the problem of assembly interface of various parts, basic car, chassis, power system and other general, weapon station, armor, etc., which can be designed in accordance with our own standardization, and then install weapons or hang armor according to demand...... "Xie Kai introduced modular design, not only for Wang Hao.

It was even more said to Zhang Huazhong and others.

The benefits of modular design become more obvious the further you go.

In the 21st century, a large number of products are modularly designed, and as long as the design problems of various basic functional modules are solved and the technology is solved, new products will appear faster.

Nowhere is this more evident than in the development of automobiles.

In any type of car, the manufacturer will introduce a base model, and then configure it according to the customer's needs......

"In the transformation of Type 63 armored vehicles, we are ready to use composite armor, but we have always been unable to make a decision because of cost issues and too long production cycle. Zhang Huazhong said.

Armored vehicles have to consider not only firepower, but also protection.

"Composite armor?" Xie Kai asked.

"Yes, hang up composite armor, so that the protection is higher. Wang Hao nodded and said.

Seeing that Xie Kai was puzzled, he turned around and went to the office to get a drawing.

Above the drawings, there is a diagram of the composition of the entire armored vehicle protection system.

"You want to make this thing into armor like a tank?" Xie Kai twitched the corners of his mouth and looked at Wang Hao.

No wonder it can't be satisfying.

This should not only be a matter of cost, but also of the production cycle.

The main reason is that such a thick armor will make the power system and suspension system of the armored vehicle all redesigned, and the structural strength problem also requires a lot of calculations.

In all likelihood, even the chassis of the Type 63 armored transport vehicle will not be able to withstand it.

Whether it was Wang Hao or Zhang Huazhong, their faces were full of embarrassment, but Wang Guilin was watching from the side and did not speak.

"At present, the steel we use to make protective armor is insufficient, and the cost of using the new tungsten-nickel alloy from the base to make armor is too high......," Zhang Huazhong explained.

Wang Hao looked at Xie Kai, but he didn't think so.

The armor material is not good, and if you want to improve the stronger protection ability, you can only make the defensive armor thicker.

"It's not a tank, I personally don't think it's much necessary. Armored vehicles need more flexible operational performance, and not in the direction of tanks. Xie Kai looked at Wang Hao and said.

He knew why Wang Hao was doing this.

The other party wants to use armored vehicles to kill the tank he created.

"You don't have a backache when you stand and talk. Otherwise, how to improve the protection ability?" Wang Hao couldn't help it, looked at Xie Kai, and said angrily.

"It is completely possible to use the structure of matrix steel plate + composite armor, the matrix steel plate belongs to the main components of the hull, and the composite armor is designed in the form of draping...... "Xie Kai is completely talking about the various designs of ZBL-09. "In order to increase speed and make the operation more flexible, it is even possible to use a wheeled design. ”

"Wheeled design is not good in off-road!" Wang Hao immediately retorted.

Wheeled armored vehicles are used more abroad, but they are not good for off-road.

There is no crawler climbing ability and trench crossing ability.

"For the time being, the wheeled type is not considered, the tank itself is not designed for urban combat. Zhang Huazhong also shook his head.

In order to avoid Xie Kai not leading them astray, he naturally would not be willing to study in another direction.

Xie Kai also did not say much, "In terms of defense, it is impossible for armored vehicles to develop in the direction of tanks." The same goes for firepower. Personally, I suggest, it is possible to develop mainly towards air defense. Of course, with advanced anti-armor missiles, it's okay too......"

The Red Arrow-73C anti-armor missile, which is the standard weapon of the ZBL-09 type.

"In fact, there are a lot of domestic studies in this area, and there are a lot of 63-type modifications. "Wang Hao has done a lot of preparatory work, and there are a lot of domestic transformations for tracked armored transport vehicles. "A lot of the renovation is in cooperation with Western countries. ”

"Yes, so many of our plans are duplicative of other people's projects. ”

Zhang Huazhong nodded.

"If you install anti-aircraft missiles and Gaoping dual-purpose machine guns on the armored vehicle to form a weapon station, it is best to be able to carry out automatic ......control," Xie Kai looked at Wang Hao.

Wang Hao's eyes lit up.

"We have this solution, and it is the most technically difficult of all the solutions. The full-size model is ...... in the workshop," Zhang Huazhong told Xie Kai.

Their work these days is not in vain.

For a few months, I thought of a lot of solutions.

Under the leadership of Wang Hao, Xie Kai followed them towards the depths of the workshop, and in the most corner, there was an infantry fighting vehicle that was completely different from other infantry fighting vehicles.

Other infantry vehicles with turrets or machine-gun turrets on them.

But in this car, there is also a turret in the middle, and the turret is low, the barrel on it is small, and on each side of the turret are two missile launch brackets with missile models on them.

"It's a bit similar to the one you proposed. However, such technical difficulties are too high, and the cost will be very high......," Zhang Huazhong said to Xie Kai.

Wang Hao also knows that cost is the biggest problem, "if you want to have stronger combat capabilities, you must be equipped with small air defense radars, advanced vehicle commander observation and sighting systems and other ......"

"To have advanced combat capabilities, you can only use advanced technology. Xie Kai doesn't think there is much limit to cost. "The weapon system, not counting the system of the armored vehicle itself, if you want to install these configurations, you have to pay extra money, right?"

"Isn't this some systematic weapon station?" Wang Hao stared at Xie Kai.

He couldn't understand Xie Kai's thoughts.

"We are engaged in armored vehicles, which are used to transport equipment for infantry to fight in tank clusters...... During the self-defense counterattack against Vietnam, everyone knows how much we suffered without suitable armored vehicles. Xie Kai emphasized.

ZBD-86 infantry fighting vehicle, the design has not yet been finalized.

There is still more than a year to go, and that kind of infantry war was originally the first armored transport vehicle in the real sense of the word after attaching importance to the role of armored transport vehicles in China.

The ZBD-86 infantry combat vehicle project, like most of the projects of the 404 base, did not consider the domestic equipment from the beginning, but exported to the Middle East and North Africa.

Compared with the domestic troops, the countries in the Middle East that are in high demand are the ones who have money, otherwise the domestic military cannot afford to develop them, and the investment will be in vain.

"That's the truth, the problem is ...... in our situation now"

"There is no problem with the funding of the base for the time being. Of course, as long as the Iranians at the base are in demand, the cost of research and development is not a problem. Wang Guilin spoke.

The issue of R&D costs, for the base, can now be temporarily disregarded.

"Iranians, our products don't have a shadow ......" Zhang Huazhong was surprised, and Wang Hao couldn't figure it out.

Nothing came out, counting on the Iranians to pay for it?

Are the Iranians so stupid?

"It's okay, he's good at selling solutions. Wang Guilin pointed at Xie Kai with a smile on his face.

"We'll have to do a good job of it. Xie Kai said. "We had to make the plan better and then bring them to this workshop. ”

Xie Kai didn't understand why the people of the base management committee didn't bring the Iranians to the 363 workshop, so many types of full-scale models, there would be Iranians in need anyway.

"Uncle Wang, why didn't you bring Iranians to this workshop?" Xie Kai asked Wang Guilin when he left.

Wang Guilin turned his head to look at the workshop behind, and then looked at Xie Kai, and had nothing to say for a while.

"Are you worried that I will fight with Wang Hao, or that I don't want to, and I won't be able to pull back on this?"

I'm not that kind of person.

"With this in mind, it's more that they haven't had a complete plan, and a lot of things haven't been fundamentally improved. Wang Guilin said embarrassedly.

It's not that the base doesn't want to sell, but that Wang Hao, Zhang Huazhong and others don't have the ability of Xie Kai.

"What we are looking forward to more is that the northern military side will come up with armored vehicles that can be coordinated. Their armored car project is about to be finalized. Wang Guilin said.

"They are also modifying Type 63, right?" Xie Kai looked at Wang Guilin.

Now the armored car of the Northern Army is definitely the ZBD-86 that is about to be finalized.

This thing was ordered by the Iraqis.

At the end of the Iran-Iraq war, both sides had a small number of ZBD-86s put into use on the battlefield during the counteroffensive phase.

"Yes, with new weapons modules, more efficient armament. The Type 63 was replaced with a 73mm smoothbore gun with a 30mm automatic cannon, equipped with Red Arrow-73 anti-tank missiles, and a number of other weapons. Wang Guilin nodded.

Sure enough, it was the ZBD-86 infantry fighting vehicle.

Xie Kai has a number in his heart, this kind of infantry fighting vehicle, the Iranians should have also seen it.

The scheme of the 363 workshop, which was almost built on such infantry fighting vehicles.

"Xie Kai, didn't you go to school?" The Iranians and the base are now negotiating about the training of the troops, while waiting for Long Yaohua to bring news about the 200-kilometer-range surface-to-surface missile.

The Iranians expressed surprise at Shekai's appearance.

As long as this kid comes, it will make them feel that the money in their pockets is dangerous.

I've always been guarding this kid from taking the money out of their pockets.

"Don't you need armored vehicles? We have new armored vehicles that can work with the 359 tank. Xie Kai said.

Alpha looked at Xie Kai with a smile on his face, "Xie Kai, you want us to reach an agreement, it's not like that, right?" There is no research on armored transport vehicles at your base at all......"

The Iranians have been at this base for a long time.

"yes, you don't have a project like this, it's not just a plan. Ihor also looked at Xie Kai with a smile.

Xie Kai didn't explain much, but told them mysteriously to take them to a place where the base was originally closed to outsiders.

The Iranians were immediately interested.

The base isn't particularly large, but there's a lot of area they've never looked at.

Originally, it belonged to the main body of scientific research, the underground department, and there was no area for them to visit. Not right, at least the underground part of the firearms study has been shown to them, although there is nothing.

"Workshop 363, the same nature as our workshop 359, which mainly studies armored transport vehicles...... All of them are the most advanced armored vehicle research directions in our country......" Xie Kai stood outside the 363 workshop and told the Iranians very proudly.

The Iranians did not take his words seriously at all.

This kid is running a train all over the place.

But after entering the workshop, the entire workshop was neatly placed with more than a dozen armored vehicles of various models, and some even carried tank guns of 100 mm caliber!

"These technologies are readily available?" Alpha is envious of China's capabilities in this regard.

Iran does not have a well-developed industrial system to support such a systematic and large research project.

"Most of them are readily available. This is part of the research projects of our base, many of which are theoretical studies, and as long as there is customer demand, it can be put into prototype manufacturing immediately. Xie Kai fooled the Iranians.

The investment in the manufacture of prototype cars, it must take time, right?

"This one, with perfect defensive performance, is the main weapon is a 30 mm automatic cannon, equipped with avant-garde anti-aircraft missiles, Red Arrow-73 anti-tank missile launch module...... The maximum marching speed is 64 kilometers per hour, and the off-road speed is between 30~40 kilometers per hour, which can fully cooperate with the 359 tank to fight. Xie Kai's boasting made Wang Hao and Zhang Huazhong on the side stunned.

That's not what was discussed before.

Wang Hao wanted to ask Xie Kai, but in the face of a group of Iranians, he couldn't be as indifferent as Xie Kai.

"Xie Kai, your models are all made of wood! they won't be the same as tanks, you sell solutions, right?"

Unexpectedly, Xie Kai nodded in approval.

"This project, if you are interested, you can cooperate with us, and then you can also get the production technology, and have a complete armored vehicle production technology......" Xie Kai said calmly.

"Really?" Alpha was pleasantly surprised.

The other Iranians also looked at Xie Kai, Wang Guilin and others in surprise.

"Definitely not a problem. We can convince the military to follow our higher authorities. Xie Kai said calmly.

Anyway, Xie Kai is determined to take out the money of the Iranians.

"You're not going to make us pay a large threshold fee like the Pakistanis, are you?" Alpha asked Xie Kai after calming down.

They are also aware of the cooperation between the 404 base and Pakistan.

It is absolutely impossible for Xie Kai to let them get the technology without paying any price.
