In the production of 203 mm artillery, Mao Yuanshan adopted two methods. One method is to exchange it in the system. The other method also established an artillery factory. The reason why we can now establish an artillery factory is also directly related to the acceptance of Jewish refugees in Europe. During this period, about 300 Jewish refugees from Europe came to the land of China. They were escorted by the escorts and entered the Chahar local government through various channels. Most of them were senior engineers. If you do not have certain skills, Mao Yuanshan would not help you leave Europe. We are not the kind of person who does good deeds. We must be rewarded in everything we do. Without efforts, there will be no reward. I have paid so much money. The reward now is to get these engineers.

In addition to these engineers, Mao Yuanshan also brought in many teachers from universities and middle schools. These people used to teach some useful techniques. After these people were brought in, Mao Yuanshan set up a school for them. He first dug out their knowledge, and then formed a research institute for them to lead a few students. This can improve his research ability here to a very high level.

The 203mm cannon was studied by a Jew. Mao Yuanshan exchanged it and gave them two cannons for them to study. Unexpectedly, after a period of time, his own artillery factory could also be manufactured. Of course, the quality can only reach about 70% of the exchange, which is very good. You should know that the artillery made by the Germans can only have an 80% pass rate. They can create 203mm howitzers in such a place without any foundation. This is already quite good. They cannot have too high requirements for others, and they have to give them a certain amount of space.

The 203mm cannon is different from other cannons. In addition to its larger caliber, its mass and weight are also greatly improved. If the 203mm cannon is launched at full speed, it can fire about three rounds per minute. If the caliber is large and the shells sink, the speed will naturally not be increased. However, the power can also be shown. A 203mm cannon can affect about seventy meters around. Although it cannot kill everyone within the range of seventy meters, it is still no problem to cause certain damage to them. His own heavy artillery regiment is finally worthy of its name.

In the past, all the 150mm howitzers in the heavy artillery regiment were carried, which was a bit unbearable for Mao Yuanshan. How could it be called a heavy artillery regiment? You know, the German heavy artillery regiments were equipped with 320mm artillery. Even countries like Japan, which are more trash in industrial areas, were equipped with 305mm artillery. We actually rely on 150mm artillery guns to rush. How embarrassing.

Although the 203mm cannon is still far behind the 305mm cannon, it is enough to have 203mm cannons on the battlefield in China. In the future, you will definitely unlock larger caliber cannons.

The weight of the 203mm artillery shell has reached 35 kilograms, and it is already very difficult to hold one person, so it is necessary to occupy two people when filling the shells. With the preparations of the two loading teams, the total number of other operators will be more than 30. For transport personnel, there must be almost forty people serving a cannon. This is a relatively developed security regiment. If it is replaced by the Central Army, the number of people will be at least doubled. It turns out that they will need more than forty people to serve 150 mm howitzers!

After the expansion of production, the arsenal can already produce five artillery pieces per month. Of course, there is no limit on redemption, but Mao Yuanshan does not want to exchange them all, and should give the arsenal a room for development.

The international price of 203mm artillery is about 600,000 oceans per unit, with a shell of 200 oceans per unit.

If it is shipped to China, the price will become 800,000 yuan per person.

While experimenting with artillery, Mao Yuanshan specially collected ten artillery pieces before testing the shooting. During the nearly half hour of shooting, various disabled tanks and armored vehicles were placed inside a land with an area of ​​two square kilometers, and various trenches and trenches were dug. Things like barbed wire were even more indispensable. Many people were invited to watch, which scared everyone. Whether it was a tank or an armored vehicle, they all turned into a pile of garbage during the nearly half hour of gunfire.

Immediately, observers from the central government wanted to buy this cannon. If this cannon is pulled to the battlefield of the Yangtze River Delta, it will not only cause huge damage to the Japanese, but even if the Japanese destroyers sail in, using this cannon can also cause certain damage to them.

However, Mao Yuanshan still rejected them. If they exported too much, it would arouse some people's suspicion. After all, on the surface, his factory can only produce five artillery guns a month and form a heavy artillery regiment, which requires at least 24 such artillery guns.

In order not to arouse others' suspicion, it is better not to create so many things, so I politely rejected them. In fact, the observers from the central government just said something casually. They also understood that the output of such things could not be high, but they should still put it forward with a try. If Mao Yuanshan develops his patriotic enthusiasm, he might be able to give them one from the five cannons every month. Any such thing is a big killer.

Japanese spy Miss Noko Natsuko also watched this test shot because it was opened to the public, mainly to expand her influence. As an elementary school teacher, she also went there.

Of course, there was a person behind him to monitor him.
