"Infantry fighting vehicles, the main role is to provide protection for the armored infantry in cooperation with the tank operation, and further provide medium and short-range fire support for the infantry, so that the tank is mainly responsible for the attack of long-range large equipment and fortifications, armored vehicles to attack short-range fortifications and light equipment, infantry is near the ground combat protection armored vehicles and tanks. Form a network of firepower from far, medium and near on the battlefield......" Liu Yijiu explained to everyone.

He had to change their minds.

In some aspects, it is better to be able to integrate and multi-functional, but in some aspects, it must be specialized and segmented.

This is very contradictory, but the development of weapons and equipment is like that. In the past, the development of the military industry in this era took a lot of detours, and Liu Yijiu couldn't even figure out what was the need to equip infantry fighting vehicles with large-caliber guns.

In urban warfare, there are heavy artillery groups in the rear, and there are planes and missiles in the sky that can be supported at any time.

And the combat vehicle, in street battles, is much more advantageous than the tank.

In field warfare, sometimes the role of tanks will not even be as mobile as infantry fighting vehicles, and their combat capabilities will not be too high.

The planes in the sky cannot be guarded against by tanks, and they cannot run at speed, so they must be protected.

In the future, infantry fighting vehicles will replace tanks for anti-aircraft and anti-armor and provide short-range fire support for squad infantry. He wanted to go directly to the armored vehicle, but in the absence of more advanced anti-aircraft and anti-armor missiles, he could not maximize the power of the infantry fighting vehicle.

"Also. In the event of such a war, a network of far, medium and near firepower on the ground will be formed. If the air is equipped with helicopters and fighters for three-dimensional firepower, then in such a state of war. How many more enemies can be resisted? Liu Yijiu's words made everyone fall into deep thought.

"Director Liu, let's just do this?" Jiang Ming didn't know how much of a role the war monster on the drawing in front of him could play after it came down. However, due to the presence of anti-tank and anti-aircraft missiles, this attack force is at least many times more powerful than the 59 tanks currently equipped in China.

At the same time, although the coaxial machine gun is missing, the spawn ability on the battlefield will be much higher.

The anti-aircraft machine gun is mainly for air defense, but in the current situation, this thing will be transformed into a high-level dual-purpose, and it will be mainly used for shooting at infantry on the ground! If equipped with two thousand rounds of ammunition......

"The T72's automatic reloading mechanism is used in it. Reducing the number of operators is a lot more space. In addition, the layout of the magazine and crew compartment needs to be modified so that it ......," Liu Yijiu said, drawing the layout inside on the drawing.

For the internal layout, he directly adopted the XM1's layout of separating the cockpit and ammunition compartment, instead of using the Soviet-style way of directly storing shells under the turret of the tank, and once hit, it is easy to detonate.

Even. He also planned to change the front-wheel drive to rear-wheel drive, and add a pair of steering wheels to the position of the original steering wheels in front, that is, to change the original five pairs of wheels into six pairs, and finally thought that this plan was too difficult to implement. Having to redesign the site is simply unrealistic.

So I had no choice but to give up. Although that would have a very big advantage for the flexibility of the tank, it was also very good for China, which was technologically weak. It's not very easy to implement.

"Director Liu, I still have a question. If we follow the welded turret we are using at present, will the strength and protection be weakened? Shen Wei always felt a little awkward to abandon the tank that had always used a round turret.

Originally, the blueprints were based on the original round turret. But now, when Liu Yijiu was painting the interior layout, he found that the circular turret would make the space smaller.

I simply brushed the floor and changed the round turret to the XM1's design with a large inclination bevel.

"According to our research, an inclined plane with a large inclination seems to have a much higher capacity than a design without an inclined plane...... Cao Feng's eyes lit up when he saw Liu Yijiu's changes

This design makes it easier to retrofit reactive armor.

Only by using welded armor can the entire armor be made easier. According to their design, there are seven layers of composite main armor 180 mm thick on the front of the turret! The thickness of the homogeneous steel armor is only seventy millimeters, mainly to add a layer of carbon fiber with high strength on it...... At the same time, the ceramic balls on it will also be inlaid into the homogeneous steel armor, and there are some ceramic columns interspersed in it at a 45-degree angle, which can effectively increase the horizontal thickness of the armor......

These designs are able to effectively counteract the kinetic energy of armor-piercing bullets. Even, two layers of hollow titanium tubes are arranged inside, mainly because the hollow tubes will have a very big impact on the direction of the jet stream......

The outermost fence shielding device for rockets that have begun to become proliferating in the world and become an anti-tank artifact. Anyway, for some practical, low-cost technology and design of the 59 Demon Reform, Liu Yijiu used all of them. Whether this thing is beautiful in the end, he just doesn't bother to care.

The weapons of war are not used by people to drive their commuting to and from work, but to kill people.

The strongest firepower, the highest defense, the most flexible operation performance, and the most powerful power system have reached a perfect balance on the territory of this 59 tank because of Liu Yijiu, a latecomer.

In the end, it is unknown whether it will be able to become the strongest Five-Nine Demon Reform in the world.

Anyway, he felt that no one would be able to surpass his magic change of Wujiu in the future. Not even for the Soviets, who designed the 54/55 series tanks!

These designs are not very difficult to implement, but are based on a lot of research. Most of the technology originated in the late 20th and early 21st centuries. This kind of tank after the magic change is no longer even 59, except for the chassis, there is no resemblance to anything else.

This is also Liu Yijiu's preparation for the next step of their own independent design of a new generation of Republic main battle tanks that can compete with the XM1 and Leopard 2, the overlords of the third generation of tanks.

"You can test this then, I'm just a suggestion, I don't necessarily say it's going to be like this......" Liu Yijiu said with a smile.

Others also laughed, Liu Yijiu is like this every time, he said, the result is much better than the original conventional, there is no need to waste time and funds to experiment.

"In addition, behind the magazine, a pressure relief plate must be installed, and when the magazine is hit and causes an explosion, the pressure of the explosion can be discharged upwards or backwards to avoid impacting the front crew compartment...... "The research results of the Americans were directly taken out and used.

As for the domestic technology is too poor, whether it can be realized, Liu Yijiu will not care, these big masters will always come up with some solutions.

"There's no need for a skirt on this side, right? It's still twenty millimeters thick, which must be hundreds of kilograms......"

"No, the side and front and back skirts must be there. This effectively protects the suspension system. At the same time, it can also block some dust. Threaded fasteners are used to connect, which will make maintenance more convenient...... "Liu Yijiu firmly disagrees with removing the skirts on both sides of the track.

While discussing, while revising, in the end, if this thing did not have tracks and a 51 caliber 105 rifled gun barrel, no one would have thought that it was a tank.

Even, the 59 tank after the magic reform, according to the current design, has a total height of only 2.23 meters, which is more than ten centimeters shorter than the 2.4 of the American M1!

It's just that not many people who discussed with Liu Yijiu were clear.

"That's basically it, and some other things that everyone needs to improve, let's revise them slowly during the experiment......" When the final discussion was almost over, the outside was already bright.

Another sleepless night.

"Director Xiao Liu, since we are currently focusing on this, should our armored infantry fighting vehicles be put in the back first?" He didn't sleep all night, and there were many things he didn't understand, Qian Dayong's spirit was not as excited as these technicians, and he was very tired.

There is a big difference between a tank and an infantry fighting vehicle.

It's just that they didn't have a chassis scheme at the beginning, so they could only design an infantry fighting vehicle with the 59 tank.

"No, it's not necessary at all right now. The fire control system can be the same on both sides, and as for the gun, since everyone thinks that it is more appropriate to use a 40-mm cannon, there is no problem. Most of the technologies are universal, even the armor, there is no problem, naturally there is no need. Jiang Ming didn't wait for Liu Yijiu to speak, so he spoke out against it.

There will be a lot of new technologies used on this tank, although many of them are very difficult, but Liu Yijiu's explanation makes them feel that these things are not very difficult to achieve for the technical reserves in the Ninth Academy base, as for the electronic system, this directly leaves room for upgrades in the future.

They now need to get a prototype and test it on firepower, defense, and even mobility.

If there is no problem, the tank will be directly put on the southwest battlefield for actual combat testing.

The bigwigs above did not completely end the war in the southwest in order to train their troops, and the monkeys were made such a gang, the three most elite all-Soviet armament divisions were completely wiped out, the equipment was greatly damaged, and the personnel were even more lost, and the Soviet Union gave them the equipment to support five divisions again, how could they swallow this breath? (To be continued......)

PS: Sure enough, I didn't pay attention to it, and I made the millimeters into centimeters......
