Until the researchers in this laboratory unlocked the door from the inside, Angela, who was quietly approaching Zhuo Fei, couldn't hear what Zhuo Fei was talking about, in order to hide her embarrassment, Angela took the initiative to introduce Zhuo Fei to the researchers who walked out of the research room. "Professor Polkin, come over here, and I'll introduce you to someone?" As the researchers removed their protective masks and hoods, Angela smiled at the gray-haired middle-aged man.

The gray-haired middle-aged man was obviously very familiar with Angela, first smiled and waved at Angela, and then whispered a few words to the other researchers, and then slowly walked over to Angela's side. "Dear Miss Angela, it's a pleasure to see you again, Natasha has always wanted to invite you to my house." Polkin shook Angela's hand with a smile, and looked at Zhuo Fei, who was standing silently next to Angela, with some surprise.

Glancing at Zhuo Fei, who was facing Polkin's big eyes and small eyes, Angela smiled and introduced to both parties, "Professor Polkin, this is the boss behind our umbrella company, Mr. Zhuo Fei, you can call him boss or general." The boss, this is Professor Polkin, who is in charge of the rocket artillery project at the institute, and the professor is from the Soviet Union, who was accidentally discovered by Vivian and helped transfer to Ruili when he ventured to Poland after being politically persecuted by Stalin. ”

After meeting Vivian in Poland and then being escorted by the Umbrella Company to Bremerhaven on a ship to China, Polkin learned the capabilities of the Umbrella Company just from what he saw and heard along the way. Knowing that this young man standing next to Angela was the behind-the-scenes boss of the umbrella company, Professor Polkin also did not expect that the behind-the-scenes boss of the umbrella company would be so young and a Chinese.

"Professor Polkin, welcome to China, as the owner of the umbrella company, I am very happy that you can work for the umbrella company." Knowing that the middle-aged man in front of him was the main researcher in charge of the rocket artillery project, Zhuo Fei smiled and took the initiative to stretch out his right hand and shake it with Polkin, which made Polkin, who had fallen into consternation, come back to his senses, fortunately Polkin can speak English, otherwise Zhuo Fei really wouldn't be able to talk to him.

The rocket artillery project is the main research project that Zhuo Fei has put forward at the beginning of the establishment of the weapons research institute, and the original intention of this project comes from a rocket artillery information obtained by Zhuo Fei from the lottery in the system. The world's first modern rocket artillery was the BM-13 rocket launcher successfully developed by the Soviet Union in 1933, at that time the rocket artillery was extremely rudimentary, directly mounted on the territory of the truck, and the range did not exceed 10 kilometers, and Zhuo Fei knew that the modern rocket artillery could not be compared at all.

However, the rocket artillery information obtained by Zhuo Fei from the lottery in the system is a domestic Type 81 rocket artillery information, compared with the guide-rail BM-13 rocket artillery currently equipped by the Soviet Army, the domestic Type 81 rocket artillery can be regarded as the real champion rocket artillery. Compared with the Soviet Army's guide-rail BM-13 rocket artillery, the domestic Type 81 rocket launcher has the characteristics of light weight, large rate of fire, and fierce firepower, and the Type 81 rocket launcher is more sudden, which is suitable for intensive shooting at long-distance and large-area targets.

When Zhuo Fei was in Germany, he did everything possible to collect rocket experts, but unfortunately Hitler had already started the research of the rocket project in advance, and a large number of scientists and scholars related to the rocket project had been concentrated by the SS into the missile test base in Penemünde, so Zhuo Fei's efforts in Germany could only be in vain. Vivian also happened to know this, so when she accidentally met the Polgin family, she tried her best to rescue the Polgin family and send them to China to settle down.

When the Polgin family was sent to Ruili, it was just in time for the establishment of the Weapons Research Institute, seeing that a large number of Jews were busy with production, Polkin, who had been treated coldly by Angela, offered to work in the arsenal himself, but Angela was transferred to the Weapons Research Institute to serve as the head of the rocket artillery project. "Boss, the information you brought is really good, much better than the BM-13 rocket launcher currently equipped by the Soviet Army, but we are not yet able to produce this rocket artillery weapon in large quantities, because the process requirements of this rocket artillery in the data are very high, and there are still too few mechanics in the research institute who can reach this level of technology."

The problem that Polkin said is also something that Zhuo Fei has been worried about, although the Type 81 rocket launcher is a product of the country's imitation of the Soviet BM-21 rocket launcher in the early 80s, and China at that time did not have advanced machinery and equipment and skilled technicians. The Umbrella Company's current machinery and equipment are already world-class, and it also has a large number of skilled mechanics from European countries, but Zhuo Fei has been worried that the Umbrella Company's current resources will not be able to produce the Type 81 rocket launcher he wants.

Sure enough, Zhuo Fei's fears were confirmed by the question raised by Polkin, who did not mention the difficulty of designing such a rocket launcher, but said that the manufacturing process would be troublesome. Rocket artillery is a group attack weapon, and if it cannot be mass-produced and equipped with troops, the lethality of a few rocket artillery pieces alone is even worse than that of building a few large-caliber artillery pieces. "Professor Polkin, do you have any solutions here?" Polkin was only the person in charge of the rocket artillery project, and if there was a problem, Zhuo Fei could only find a way to find him.

Polkin pondered for a while, then raised his head and said to Zhuo Fei, "Boss, I admit that this kind of rocket artillery mentioned in the information is much better BM-13 rocket launcher, but we also have to admit that it is difficult to produce on a large scale according to our current technological level, and the four curved fins at the tail of the missile body alone require superb craftsmanship." What I want to say is that if all you need is a long-range and large-area coverage weapon, I personally think that the BM-13 rocket launcher that the Soviet army is currently equipped with is very good, and it is completely okay to copy the BM-13 rocket launcher according to our current level of technology. ”

Imitation BM-13 rocket launcher? After listening to Porkin's proposal, Zhuo Fei thought to himself. During World War II, the Soviet army relied on rudimentary imitation BM-13 rocket launchers, but the German army suffered a lot, and an eight-track BM-13 rocket launcher could cover a large area. It's just that Zhuo Fei can't look down on the power of the current Soviet army's imitation BM-13 rocket artillery, compared with the power of the Type 81 rocket artillery, the power of the Soviet-style BM-13 rocket artillery is nothing at all.

Xu saw the hesitation in Zhuo Fei's heart, Polkin turned around and pointed to the metal cylinder on the table that had been sealed, "Boss, I know you are worried that the rocket artillery weapon we imitated is not powerful enough, but if the rocket artillery body we imitate uses this accelerant that I tested, the rocket artillery we imitate will hit farther than the BM-13 rocket launcher, and the weight of the explosive can be increased in the warhead of the projectile body." ”

"Oh, tell me about it." Hearing that Polkin already had a corresponding solution, Zhuo Fei couldn't help but feel energetic, and hurriedly asked Polkin to tell the details. Although the Umbrella Company said that in the name of helping Jewish refugees, it privately obtained a lot of heavy equipment and weapons from the German army, but compared with the menacing Japanese army, the weapons and equipment currently mastered by the Umbrella Company are obviously insufficient, and the development of new rocket artillery is too important for Zhuo Fei and the Umbrella Company.

Polkin didn't take it seriously, and directly picked up a model of the BM-13 rocket launcher and explained it carefully to Zhuo Fei, "Boss, you see, the BM-13 rocket launcher currently equipped by the Soviet army, they use smokeless gunpowder as the projectile power, but smokeless gunpowder limits the range of the BM-13 rocket artillery, although the Soviet side has improved the BM-13 rocket launcher many times, but they can't break through the biggest obstacle of smokeless gunpowder." ”

Polkin put down the rocket artillery model in his hand, and instead pointed to the metal cylinder placed in the laboratory and smiled, "I have figured out a method that can replace smokeless gunpowder from the information you got from the boss, but this method is still being explored, if my idea can become a reality, I think the range of our rocket artillery projectile body should greatly exceed all types of rocket artillery weapons currently equipped by the Soviet army." ”

With Porkin's current explanation, coupled with the scene he saw through the glass window just now, Zhuo Fei can already determine what he just saw, and he can already be sure that the solution mentioned by the former Soviet rocket expert in front of him just now should be to fill the rocket artillery body with liquid fuel. Filling the rocket artillery body with liquid fuel, Zhuo Fei couldn't help but be overjoyed, wouldn't the rocket launcher that uses liquid fuel as the power be almost the same as the V2 rocket that the Germans were researching?

Zhuo Fei has long known that the Germans are working on a long-range weapon that can cross the ocean and directly attack the British mainland, but Zhuo Fei will never call this weapon a V2 rocket, in his understanding, this weapon should be regarded as the earliest missile in the world today. With missiles in hand, I have them in the world, and after carefully discussing with Polkin, Zhuo Fei immediately issued a series of orders to Angela and Bowman.

"All researchers from the Weapons Research Institute who meet Professor Porkin's requirements will be sent to join this group, and all the materials we have in reserve will be open to Professor Porkin's ongoing project, and from now on, the base will strengthen the defense of Professor Polkin and the team members, and do everything possible to meet Professor Porkin's project requirements." Angela and Bowman were still a little incomprehensible to the series of orders issued by Zhuo Fei for a while, but Zhuo Fei explained to the two in private.

"Our umbrella company looks quite strong, in fact, we don't have any real killer features, once what Professor Polkin researches can become a reality, all future war models will be rewritten, and our umbrella company will benefit from it for life."
