Chapter 1756: The importance of air supremacy

Germany is not stingy to show its military power, and up to now, it is the best way to show its military power. It is the best way to win the war without fighting. In the later generations, the United States will display its aircraft carrier if it doesn’t pleasing to the eye. Now, Germany shows it. In a more intuitive and scene, Germany’s huge fleet is invincible. Today is Greenland, tomorrow is Canada, and the day after tomorrow is the United States.
Who can stop Germany’s cross-sea landing is so powerful that everyone will be in awe when they see it. Germany is invincible.
The radio waves spread all over the world and also reached the United States.
The TV signal is medium wave, and it seems that it must be transmitted by relay, but after searching for a long time, no information can be found. In the era without satellites, how the TV signal between Europe and the United States is transmitted, everyone should be able to spread it well.
White House.
This ending, everyone expected, when the interception at sea failed, the fall of Greenland was only a matter of time, and now, when seeing the large-scale landing of Germany, it still makes many people's faces ugly.
Those landing ships, overwhelming the sky, seemed like locusts. When there was no end, those helicopters attacked the beach in advance, and those naval guns made everyone tremble in their hearts. The United States can block this fierce offensive. Is it
Germany is not afraid to reveal their secrets. This time it is almost a complete show. The cross-sea landing of Germany is roughly in this style.
This is showing off their strength and demonstrating to the United States. It is quite easy for them to cross the sea to land in the United States.
Now, in the video, as the landing ship directly grabs the beach, the tank moves on. It is conceivable that the next step is to easily capture the prisoners.
"The Germans are putting pressure on us and want to use this method to undermine our confidence and even force us to surrender." Roosevelt said. "The Germans are wishful thinking. We will never succumb. Now the Germans have done so. It’s all shown, and we have to fight against them with special tactics."
Roosevelt never lost his confidence. Each of the Big Three of the Allied Powers in World War II had perseverance.
Now, Roosevelt would never be afraid because the Germans showed great strength. He believed that all of this could be solved.
"Yes, Mr. President." Arnold said. "The Germans exposed their tactics in advance, which created opportunities for our counterattack. The reason why they can land so blatantly now has a big premise. They Completely occupy the air supremacy."
Without air supremacy, there would be no sea supremacy. The facts now have gradually explained this point.
If one's own side continues to dispatch a large number of warplanes, then it is impossible for the opponent's battleships to get so close to the coastline. Your own dive bombing opportunities will break through their defenses and bring death to them. At the same time, those landing ships will not be able to land on the beach. , A large number of battle opportunities to sink them.
It’s impossible for those helicopters to slosh and attack the ground. In short, as long as they have air superiority, they are not afraid of anything.
When Germany does land in the United States across the sea, the United States will not hide any strength. Thousands of battle opportunities will let the German fleet know what the Great Wall in the air.
After Arnold finished speaking, the people present nodded, and even the navy agreed that if there were enough fighters, the navy’s landing operation would definitely not be so easy.
"So, now we must continue to speed up, build more fighters, and train more pilots." Arnold continued. "At the same time, we must also pay attention to the manufacture of new aircraft. There are signs that the Germans have begun to develop the first generation. Jet fighter."
Secrets cannot be hidden. Although the Germans want to try their best to keep their jets secret, they have been used in battle several times, and the US intelligence system has noticed that this kind of propeller is not needed, and the speed is still very fast. aircraft.
The jet plane Roosevelt has everything to do. It is impossible to be familiar with every weapon. When he heard Arnold talk about jet planes, Roosevelt was also an outsider.
"Now, the speed of the fighter aircraft has reached a critical point. If you continue to increase the speed, then the tip of the propeller will exceed the speed of sound. At this time, the speed of sound will be like a wall, breaking the propeller. I want to continue to increase the speed of the aircraft. You have to change the power system, jet backwards, and the plane flies forward." Arnold said, "It's like letting go of a balloon and flying forward. This is the principle of a jet."
In fact, the theory of jets has been around for more than ten years. As early as the 1930s, the British began to develop them. However, the progress has been very slow, and it was not taken seriously. Stimulated by the German jets, Britain began to accelerate development.
At the same time, American jets started even later, especially since the United States does not have any technical pre-research, almost all of the main jet engines come from the United Kingdom.
Now, as the United Kingdom is already a government-in-exile, most of the talents of the United Kingdom have been taken over by Germany. It is not easy for the United States to start the development of jet aircraft.
Hearing what Arnold said, Roosevelt immediately realized the key to the technical problem "Do we have the talents in this area do we have the technical foundation?"
Now, the United States is not afraid of investment, it is afraid that there is no technology~EbookFREE.me~ Now, what they need is time.
Hearing Roosevelt’s words, Arnold also shook his hands. How did he know so much?
As a result, his eyes turned to Hoover, who was in charge of relocating the exiles from Britain. I hope he can understand.
Sure enough, Hoover's eyes rolled around and he said, "If you talk about jets, Sir Frank Whittle is the leader, but after the fall of England, we lost his news. However, we have come to our United States. , There are other people, such as Hein Constant, who also has a lot of research on jet engines, we can contact him."
This is the foundation of an old capitalist country with a huge talent pool. Dr. AA Griffith from the University of Liverpool in the United Kingdom once published a thesis on the aerodynamic theory of turbine design, using gas turbines as a power unit for aircraft. The idea was clearly put forward for the first time. At the same time, he also conceived an axial flow gas turbine propeller propulsion device with a complete compressor and turbine structure.
Later, his research inspired his colleague Hein Constant, who brought Griffith's many theoretical results to discuss with the well-known gas turbine manufacturer Metropolitan Vickers to design this new type of aircraft engine .
Unfortunately, the plan has just begun, and the war has begun. With the help of the American Embassy, ​​Hein Constant got rid of the surveillance of the German Gestapo, and came to the United States in a hurry. It seems that he still has no livelihood.
It happened to get him to lead the research of jet engines. At the same time, the development of the whole machine should be launched immediately.
Can't lag behind Germany on jet projects
"Mr. President, we are about to go bankrupt." When Hoover accepted the assignment and once again submitted an application for funding for scientific research, US Treasury Secretary Morgenthau said to Roosevelt, crying.
