Open an aircraft carrier to fight against Japan

Lin Yuan thought of this and said: "Mr. Swart, I will not give up Poland. I said in the Tsarist era that I would support Poland's independence."

Swat smiled and said, "Mr. Lin Yuan, Poland has become independent with our support, and we have helped you achieve your goal, haven't we?"

Lin Yuan sneered and said, "Poland must become independent with the support of our China."

Lin Yuan's words were very firm, there was no room for discussion, and Swart didn't know what to say. After being silent for a minute, Swart laughed softly: "Mr. Lin Yuan, our German Empire has already done a great deal. Concession, you shouldn't be so aggressive, right?"

Lin Yuan said with a smile: "Great power struggles are not trivial disputes between neighbors. How can you be humble?"

Swat smiled and said, "Mr. Lin Yuan, you don't want Beijing to be hit?"

Lin Yuan was startled and asked, "Beijing has been hit? What do you mean by that?"

Swart smiled leisurely: "Our German Empire has recently developed a new type of weapon that can directly hit Beijing, China from Germany. You don't want to try it, do you?"

After hearing this, Lin Yuan was taken aback for a moment, thinking in his heart that it was a weapon that could directly hit Beijing, China from Germany?what is that?Germany is more than 8000 kilometers away from Beijing. With such a long distance, artillery is definitely useless. Germany has a tradition of manufacturing large-caliber heavy artillery. For example, the famous "Dora Cannon" in my era, but no matter how powerful the artillery is It's impossible to hit [-] kilometers, right?

Lin Yuan frowned, and asked tentatively, "What weapons do you have?"

Swat laughed and said, "I don't know much about these things either. Let me call you someone who understands these things and let him tell you in person."

After finishing speaking, Swart called his assistant to him, gave some instructions in a low voice, and the attendant walked out, and brought a person in because of inconvenient time. Lin Yuan looked up and saw that the young man was the one he thought was special just now. .

The young man walked up to Lin Yuan and Swat, and Lin Yuan asked someone to move a chair for him. The young man was a little cautious in front of Lin Yuan and Swat, and he seemed timid, and he only dared to sit on half of the chair with his buttocks.

Seeing him like this, Lin Yuan couldn't help laughing, and said, "Young man, please introduce yourself first."

The young man hurriedly stood up, Lin Yuan waved his hand and said with a smile, "It's all right, you can sit down and talk."

The young man smiled apologetically, sat down again, and said, "My name is Herbert. I am a student at the Technical University of Berlin in Germany. My teacher is Tsiolkovsky."

Lin Yuan was surprised when he heard this name, because Tsiolkovsky was none other than the father of rocketry in his era and one of the founders of astronautics!It was he who first expounded the basic principles of rockets and started the human spaceflight industry.

Lin Yuan asked: "Isn't Tsiolkovsky Russian? Why did he go to Germany and still teach at the Technical University of Berlin?"

The young man replied: "The old man was persecuted by the tsar, so he went to Germany."

Lin Yuan nodded. Tsiolkovsky is engaged in rocket research, which is considered an applied discipline compared with mathematics and physics, so Lin Yuan did not bring him to China.

Herbert asked at this time: "Mr. Lin Yuan, have you heard of my teacher?"

Lin Yuan thought to himself that your teacher is so famous, how could I not have heard of it, but he just said lightly: "Yes, I have heard of him, he studies rockets, well, let's not talk about him , tell me about your weapons."

There was a burst of excitement in Herbert's eyes. He took out a pen and paper from his pocket, drew a ball on the paper, and said, "This is our earth. There is a layer of air outside the earth. We call it the atmosphere. All weapons now fly inside the atmosphere, but our weapons can fly outside the atmosphere."

"After this kind of weapon flies out of the atmosphere, it will move around the earth under the action of the earth's gravity. We can control its trajectory so that it will fall back to the earth when it flies over the enemy's head, so that it can attack the enemy. strike."

While Herbert was talking, he was writing and drawing on the paper. Lin Yuan secretly laughed in his heart. After talking so much, didn’t he just want to say that you have created a ballistic missile?But the technology of ballistic missiles is extremely difficult, especially long-range missiles with a range of more than [-] kilometers. With your German technical strength, you can't make them at all. At most, you understand the basic principles of ballistic missiles, but you understand the principles and can be manufactured. It's two different things. You guys want to lie to me after you understand the principle. Isn't this just a daydream?

Lin Yuan guessed right. Germany is indeed researching ballistic missiles, but their research is at an extremely early stage. The missiles can hit up to 100 kilometers, and even Russia cannot reach more than 100 kilometers, let alone China.

The main body of a ballistic missile is a carrier rocket, and with the addition of a warhead, it becomes a ballistic missile. The load capacity of the carrier rocket is extremely limited. The carrier rocket with the largest load capacity in Lin Yuan’s era can only carry more than a dozen tons of items. These items are all explosives and have little power, so ballistic missiles are only powerful when equipped with nuclear warheads. The world of this era still doesn't know about nuclear fission.

Lin Yuan didn't directly expose Herbert, but said with a smile: "What's the name of your weapon?"

Herbert said proudly: "It's called a super long-range shell!"

Lin Yuan nodded and asked, "How did your ultra-long-range shells fly out of the atmosphere?"

Herbert immediately listed a piece of calculation formula on the paper, and said: "According to Newton's law of universal gravitation, as long as the speed of the super-long-distance projectile reaches..."

Lin Yuan interrupted him and said with a smile: "You don't need to tell me these things, I understand them too, let me ask you, what do you use as fuel for your ultra-long-range shells? Is it liquid hydrogen and liquid oxygen? Your industrial level Can you extract liquid hydrogen and liquid oxygen with sufficient purity? How do you control your ultra-long-range projectiles flying outside the atmosphere? Has your electronics industry reached the level?"

Lin Yuan threw out a series of questions, and Herbert's face turned pale and red, because Lin Yuan's questions had already exceeded his knowledge, and he couldn't answer them. Lin Yuan smiled and said, "Your super long-range shells seem to If you can’t reach China, you’re here to lie to me.”

Herbert and Swat were surprised, and Lin Yuan smiled and said, "You don't have to be surprised, your super long-range shells are not easy to use, I will show you ours."

Herbert hurriedly asked: "Does China have weapons that can reach beyond the atmosphere?"
