Just when Stuttenberg was running towards the cabin like crazy, Bo Yi was leaning in front of the warm fireplace and carefully reading the letter in his hand. This was just received yesterday afternoon. Then Bo Yi used

It took most of the night to decipher this letter written by Wu Yunzhe himself using a book from the Republic of China period.

There is no other way to use such a secretive writing method. After all, the all-pervasive KGB is famous all over the world for spying on other people's letters. In addition, it contains some mention of the development progress of two types of recoilless artillery. To be on the safe side, I

Before leaving the country, it was stipulated that all correspondence should be written in secret.

The specific operation method is simple to say, that is, use a reference book as a code book, use the stroke number of the basic text to determine the number of pages, rows and columns of the code book where the required text is located, and so on, you can pass the code

The real content of this book sounds very high-level, but it is very troublesome to do.

Take the most basic letter writing as an example. It cannot be full of words that cannot be understood. It must at least have the appearance of a letter. Otherwise, even a primary school student can see that there is something fishy in the letter.

A secret letter must be written like a real "letter" and must also meet the requirements of the codebook, which is a great test of the writer's writing skills.

Bai Yi doesn't know the situation in China. Anyway, he has to put in a lot of effort every time he writes, so that it is not easy to decipher. Especially long letters, it takes a long time. At this moment, Bai Yi

In his hand was a typical long letter, which took Bai Yi most of the night and an entire morning to finally decipher.

The letter mainly introduced to Bai Yi the development status of two recoilless artillery pieces during this period. It turned out that after Bai Yi left, Wu Yunzhe, as the director of the R&D Planning Department of the Ministry of Ordnance Industry, officially took over the development work of the two recoilless artillery pieces.

Thanks to the notes left by Boyi and the extensive application of finite element analysis, the development progress progressed rapidly.

By the time Bai Yi left for Siberia, the two recoilless artillery had already entered the prototype trial production stage. It just seemed that God did not want the recoilless artillery development team to complete it overnight. The recoilless artillery project entering the trial production stage was like

It's like hitting the ceiling, and you can no longer buy one step ahead.

There is only one reason for this, and that is two words of ammunition!

Different from other weapons and equipment, the relevant supporting ammunition is first available, and then the relevant launching system is planned based on these ammunition. On the contrary, the recoilless artillery development team first has the relevant launching system, and then develops a matching launch system.

The reason why the matching ammunition is so simple is that the leader of the original group was a time traveler.

The two prototypes of recoilless artillery he developed are both classic weapons and equipment from previous generations. One is a Swedish classic equipment known as a Western RPG. Until the 21st century, people were still confused as to whether it was a recoilless artillery or a rocket launcher.

Carl Gustaf" recoilless launch system.

The other one is even more ridiculously famous and can be called a typical representative of the RPG-7 rocket launcher. Since the firing principles of the two pieces of equipment are based on the firing principle of recoilless artillery, Bai Yi simply temporarily returned the two pieces of equipment to the RPG-7 rocket launcher.

They are classified as recoilless artillery. As for how to divide them in the future, that will happen after the development is completed. Before that, in order to improve the efficiency of equipment research and development, Bai Yi is better to group them together.

It is precisely based on the two classic pieces of equipment from his previous life that Bai Yi feels confident. After all, these two pieces of equipment have frequently appeared in textbooks since the day he entered the military academy. Bo Yi knows every technical feature of the two pieces of equipment by heart.

Well, he is quite familiar with it, so Bai Yi is not afraid of the embarrassing situation where the two recoilless artillery have tubes and no ammunition, because as long as he, a time traveler with golden thighs, is around, it is simply impossible!

But God's calculations are worse. Just as the project is progressing smoothly, the "Double Diversion" project has also entered a crucial preparatory stage. In order to complete the goal as soon as possible, Bai Yi was transferred from the project team and rushed to Siberia. Although before leaving, Bai Yi

Yi tried his best to write down all his ideas, but due to time constraints, it was inevitable to omit details. Especially in terms of ammunition, there were many descriptions that were not very detailed.

Such a recoilless artillery development team is like a toddler who suddenly loses the support of the armrest and falls inevitably. The biggest setback among them is the No. 2 recoilless artillery project that was born out of RPG-7.

The primary mission of this equipment is to implement squad-level anti-tank operations.

Therefore, relevant anti-tank ammunition is indispensable, but the problem is that China has no experience in the development of relevant ammunition before. Although the Baiyun Factory has several German Panzerfaust samples and related drawings, it has indeed served as a reference after studying them.

Meaning, but that's all.

For example, the internal medicine cover is known to be copper, but due to the lack of resources in Germany at the end of the war, in order to reduce costs, a slight alloy was added to the copper medicine cover; and the basic component of the shaped charge is "black"

"Sokin", but it is not complete. It contains a lot of additives that contribute to concentrated energy explosion. This aspect cannot be solved based on the actual situation in China. As for the propellant in the second half, it is too simple and cannot be satisfied at all.

Basic performance of supporting ammunition for No. 2 recoilless artillery.

All in all, the ammunition of the German "Iron Fist", apart from giving the recoilless artillery development team a general direction in terms of structure, has little other effect. In some aspects, it even disrupts the thinking of the development team members, so as to

As for the delay in getting this anti-tank ammunition out.

In desperation, Wu Yunzhe could only write to Bai Yi, hoping that Bai Yi could think of a way. After all, the volunteer officers and soldiers on the Korean front were looking forward to the stars and the moon for this kind of individual anti-tank equipment, especially after the third battle.

The volunteers who crossed the 38th Parallel discovered that the terrain difference between the north and the south was so huge:

The north is densely covered with mountains, but the south is flat. When fighting in the north, due to the restrictions of high mountains and ridges, the mechanization of the US military could not be carried out; but south of the 38th parallel, the mechanized troops of the US military were at home in the flat wilderness.

Galloping freely, if you can't hit the accelerator, you will hide far away, and when the time is right, you can use full power and quickly make a comeback.

Often at this time, the volunteers who relied on two feet were bitten by US tanks before they could evacuate to a safe area. They had no choice but to use their flesh and blood to collide with the steel of the US military again and again. In this way, the casualties on the front line were only a few.

It is conceivable that because of this, the Volunteer Army Headquarters has repeatedly urged the No. 2 recoilless artillery to be brought out as soon as possible!
