Engine, gearbox, these problems have been solved, it can be said that the heart problems of the three generations of tanks can be solved perfectly, and for Zhu Lao, other problems of the three generations of tanks are constantly being solved one by one.

The advanced fire control system is developed by the team led by Cao Jianli, in fact, research and development is nothing, more important is production, the most important thing is the production, the biggest constraint of the trans fire control system is how to produce qualified products, in addition to these, there is naturally the tank gun.

The 125 mm tank gun has come out, and it is equipped with the current 85 tank, and it is being marketed to the outside world, compared with the 105 mm gun, its performance is strong enough, but it is still not enough to meet the standards of the third generation of domestic tanks, it needs greater chamber pressure, more advanced shells, so these also need further research by artillery research and development personnel.

Qin Zhenhua was also clear about this, so he followed up with the matter of the Second Machine Factory.

"Zhu Lao, after visiting our diesel engine ignition, you should also go to the second engine factory to have a look, give them some pressure, save them from knowing about foreign trade projects all day long, and then put the research and development of our tank guns in the back of your mind." Qin Zhenhua said.

In this way, it is naturally a joke, the second machine factory knows the weight, and also knows how important the third-generation tank project is, how can it not do its best, it's just that the improvement of technology needs to be accumulated little by little, and for its own third-generation tank, if it can't be done in one step, then first test the existing barrel, and wait until the new tank gun is developed and then installed, and the new second-phase ammunition and third-phase ammunition will be installed after research and development, and there is no problem.

Hearing Qin Zhenhua's words, Zhu Lao said to Qin Zhenhua with a smile: "Yes, of course I want to go to the Second Machine Factory to have a look, I heard that the Second Machine Factory has been quite busy recently, and there are many production and R&D tasks. Especially that kind of super cannon. ”

Speaking of super cannons, Qin Zhenhua thought of what he saw before he came back from the Second Machine Factory, and couldn't help but say: "Zhu Lao, they have super cannons there, the largest caliber, which has reached 203 mm, but that kind of cannon is too bulky, and if there is no tracked chassis, it is not convenient to operate at all." ”

Tracked chassis? Hearing Qin Zhenhua's words, Zhu Lao thought of something and said: "Crawler chassis, of course it's not difficult, we have it at hand." ”

What, we have it? Hearing Zhu Lao's words, Qin Zhenhua's eyes suddenly lit up: "We have it?" Where is it? ”

What is it called? There is nowhere to find the iron shoes, it takes no effort to get it, you just need such a chassis, and you actually have a ready-made one?

"Captured from the south at the front." Zhu Lao said: "It should be in the hands of the army, and if the Second Machine Factory wants it, then let the Second Machine Factory apply for it." ”

Two days later, when Zhu Lao was still inspecting the second machine factory, the M107 self-propelled howitzer was transported.

"The Americans' large-caliber howitzers, there are 175 mm and 203 mm, these two howitzers, are placed on the same chassis, this chassis is specially designed, aluminum alloy welded, no turret, the whole vehicle is composed of two parts: artillery and chassis. So, there is also a saying that the M110 type 203 mm self-propelled gun mount and the M107 type 175 mm self-propelled gun mount. ”

Looking at this equipment, Zhu Lao explained with a smile.

Before the development of tanks, Zhu Lao was originally studying artillery, and he was naturally very familiar with the Second Machine Factory, and he was also very clear about the artillery of various countries in the world, and now, looking at the M107 self-propelled howitzer in front of him, he also began to explain at this time.

This kind of cannon, if you go on the fully enclosed turret, you can imagine how large and bloated it will be, so now such a structure is very simple, easy to reduce the weight of the whole car, but the combat part has no armor protection is the biggest shortcoming, and it is nicknamed the gun carriage.

Due to the large number of people in the entire gun squad, only 5 crew members, that is, the gun commander, the driver and 3 gunners, were qualified to sit on the M110 car, and the rest were on the M548 tracked ammunition

on the transporter.

Now, the big guy is looking at this monster, and he is very excited, Xie Huimin has a feeling of being a treasure, every time he follows Qin Zhenhua, there is always something good to happen, this kind of big guy, we actually have it, I really didn't expect it, in the past, there was no attention to this, I didn't even know, we have it ourselves.

"Director Xie, this gun carriage, you have to study it carefully, see how they are fixed, how to use them, if they can be sold in the future, let's find a chassis in a machine factory and improve it." Qin Zhenhua said.

Xie Huimin nodded: "Yes, of course, but it's too late to improve now, I think, we can put the 203 mm gun on this chassis first, just to participate in this international defense exhibition." ”

The cannon above is still 175 mm, but the installation method of these two cannons is the same, so your own 203 mm cannon can also be transplanted.

As he spoke, he began to study the fact that these two cannons were mounted on the same model of the M158 gun mount. The artillery uses a screw bolt, an M35 combo firing machine, a variable hydropneumatic re-entry machine and a pneumatic balancing machine. These devices can be fully improved with their own.

The artillery direction machine and the high and low machine are all toothed arc type, which are mainly operated by hydraulic power, and can also be manually operated in case of emergency.

Looking at the back, there is a special loader, consisting of a bomb loser and a loader, which is hydraulically operated. The shells of this big guy are also very large, so there are two bomb throwers in the bomb loser, just like the crane arm, which lifts the shells and sends them to the loading slide; Slide along the slide rail to reach the tail loading position; Using the push lever to push the bullet into the chamber, the whole process is decent and not complicated.

"In my opinion, there are not many things that need to be improved, even if it is directly stuffed into our 59 tank chassis, there is no problem." After reading this, Xie Huimin let out a long breath and said.

There is a sample, you can refer to it, the overall study is completed, this modification, it should not be complicated.

"How to do it, it's your business, but although this matter is important, it is also your responsibility to develop a powerful 125mm gun for our third-generation tank, how are you doing now?" Qin Zhenhua asked Xie Huimin this question with a smile.
