In this way, the time of the day passed quickly, and at four o'clock, the group went home with a few tired little guys, but waiting for them to have homework, and what scared them the most was that Su Ya's sister-in-law assigned them another essay, asking them to write about their feelings about today's spring outing. Li Zhao listened to this homework and almost laughed out loud with a pig cry, this is a bad taste for all adults, right? What a trick to deal with children.

After a day of playing, Li Zhao also quickly returned to work, that night, Li Zhao started his aircraft design career again, this work is a long-term process, but also a very fine work, any problems will cause casualties, not to mention that this is still a relatively backward era of the aviation industry, Li Zhao does not know whether he can design a qualified ejection seat for the aircraft, that accident is unimaginable.

It is also for this reason that Li Zhao is very cautious about the design this time, although he has drawings as a reference, but if he wants to realize the third-generation aircraft in this era, the difficulty is also conceivable, and there are too many problems to consider. In addition to this design giving Li Zhao a headache, several unfinished tasks in the factory also made Li Zhao tired, but there was no way, these jobs must be completed, who let Li Zhao have to do so many projects.

Of course, with the busy, there are still a lot of results, this is not in the middle of April, after a period of processing, the tank production line was built, and now the factory can produce its own tanks, and the most important thing is that after communication with the superiors, the entire tank production is placed in the 998 factory, of course, the turret is still produced by the military factory, but the armor is no longer manufactured in the tank factory, after all, this is too resource-consuming.

You must know that the armor produced by the tank factory, the armor steel in it is produced by the 998 factory, and the steel needs to be sent to the tank factory first, and then processed into armor and then transported back, isn't this looking for trouble? And the factory can also produce glass fiber, there is no way to produce nylon in the factory, in this case, of course, it is the most cost-effective to control the production in their own hands, but this output, that is really small, basically a week to build a car.

There is no way to do this output, after all, there are only so many orders per year, but this is better, the order is less, once the problem is found, the loss will be much smaller, after all, the time for this tank to test is still relatively short, and the number of tank tests is relatively small, so far, a total of ten cars have been produced, which is only this number of two cars that have been manufactured together, and there are not enough test scenes.

At present, only the experiments of the snow fields, deserts, and grasslands have been carried out, and as for the high temperature areas and plateaus in the south, no tests have been carried out, and Li Zhao does not know what problems will occur in these environments, but there are no conditions for the test in these areas at present, and the high temperature areas in the south will mainly involve the problem of leakage, and the superiors feel that there is no guarantee that there will be no leaks after arriving there, so they did not consider the test there at all.

Moreover, in the southern zone, especially in mountainous areas, this kind of heavy tank is not suitable, that kind of terrain, more suitable for medium or light tanks, as long as it can increase the firepower, it may be better than the heavy type. The plains, deserts, and grasslands in the north are very suitable for heavy tanks, and the first to equip these tanks are indeed placed in the direction of the north and northwest, and they are all secret troops.

In the process of transportation in the future, it will all be sealed, and when it leaves the factory, it is equivalent to saying that a large wooden box needs to be built directly on the train, and basically it will not appear in the public's field of vision in the short term. However, regarding the painting, Li Zhao was more satisfied, and after the selection of the superiors, he finally chose two kinds of wilderness camouflage and grassland camouflage, and at the same time, the tank was also equipped with camouflage nets such as snow camouflage, and the net can be changed directly by changing the environment.

Time quickly passed another week, to April 20th, today is the first tank off the production line, today is also a lot of guests here, do not know each other, there are forty or fifty people here, but most of these people are generals in the army, at least are major generals, Li Zhao is also the first time to see so many generals. And what surprised Li Zhao the most was that the generals who came this time, as far as Li Zhao saw, there were six people wearing military uniforms.

This time it's really a big scene, but this tank is worth so many people, although in Li Zhao's opinion, it is still very backward,

After all, the electronic system is really rubbish, and the artillery and armor have reached the standard of the third generation, and the electronic system is at most a little more than the level of the second generation, but in this era it is the most advanced, there is no one, after all, this tank has carried out live firing of 105 mm artillery.

For the tanks of this era, basically except for the tank itself, there is no tank that can penetrate the armor of this tank, and as long as it is hit by this tank, then basically no tank in this era can take a shot without anything. You must know that when this tank is tested for gun, the use of tungsten alloy tail stabilized shelling armor-piercing projectiles can penetrate 800 mm average armor.

Now this tank itself can defend against this artillery, after all, Li Zhao estimated that the thickness of the armor of this gun is equivalent to the average armor of 1.2 meters thick, but the armor of this tank is too thick. However, it should be optimized later, and now the factory can produce its own armor, and the optimal thickness of the armor will definitely be tested later, now the tank is too heavy, the engine is a little smaller, and it is a little too fuel-guzzling.

However, this test takes time, and now the factory has only just begun to produce armor, and the professional armor research group has just been established, and this process takes time.

The assembly line of the tank is relatively simple, mainly some auxiliary installation equipment and driving, and there are not many personnel needed, the real need for personnel is actually the production personnel of each part, but those are separate workshops, not here. And those workshops, to be honest, really don't have anything to look at, either in iron, or machining, it can be said that people who don't understand can only look lonely.

The assembly workshop is different, and it is more interesting to look at here, such as the tank mobile station, which is hoisted around in the sky with a crane, and it looks quite spectacular. And there are a lot of tank parts waiting to be installed here, all of which can be assembled to assemble ten units, but because there are too few orders, there are not many workers.

For the installation of these tanks, the factory is not in a hurry, what is required is to work slowly and carefully, and be sure to ensure that each tank leaving the factory can reach a perfect state, after all, the installation time of each tank is given a week.

In order to let the guests intuitively understand the assembly process of the tank, the factory also let the assembly personnel demonstrate all the assembly processes today, so that everyone can understand the assembly process of the tank more intuitively, but after watching the assembly process, one of the generals asked: "If you produce at the fastest speed, how much can the annual output be achieved under the current conditions?"

Li Zhao didn't expect them to ask this, but this question is simple, in fact, Li Zhao designed the annual output of more than 1,000 tanks for the tank workshop, but obviously the military could not order so much.

In fact, this output is already very low, in terms of the current scale of the 998 factory, if the full production of tanks, the annual output is estimated to be able to do 3,000 vehicles, in fact, this is also very simple, because there are many workshops in the factory to produce tanks with slight changes, just need to be equipped with some auxiliary equipment, after all, when the tank is installed, the large parts are hoisted by cranes, and even the movement of the tank itself is lifted by cranes.

Li Zhao also replied truthfully: "As long as the factory mobilizes production capacity now, it can probably reach an annual output of 1,000 vehicles without affecting other parts of production, and if it mobilizes production capacity, it can produce up to 3,000 vehicles per year."

Listening to Li Zhao's words, the leaders nodded with satisfaction, they are very satisfied with this output, but they obviously have no way to place so many orders, you must know that the factory has now been mass-produced, and the final cost has been calculated, which is similar to Li Zhao's estimate, the cost is about 2.8 million, of course, this price is mainly because the output is too low, if the output can rise, it is estimated that it can be cheaper by three or five hundred thousand.

The time soon came to ten o'clock, and the tank was also hoisted out of the installation line, and now the tank has completed the inspection of the whole vehicle, and only needs to go to the test site for basic inspection, and it can be delivered. And this tank has also been painted with camouflage, using steppe camouflage,

Soon the tank was put into the open field, and when the workers removed the hoisting rope, everyone gathered around, and several generals got into the tank as soon as possible.

Seeing this situation, Li Zhao didn't know what they thought, so he directly arranged for someone to refuel the tank, and Li Zhao also called Brother Su Ya over, this time such a good performance opportunity, of course, he was going to call him over, think about it, the director of the tank factory, the tank is very slippery, isn't it impressive? When it comes to him in the future, there will definitely be people who say, "Are you talking about the factory director who is very slippery at driving tanks?"
