Germany does not hesitate to show its force, and now, showing force is the best way, without a fight and surrendering soldiers, in the future, the United States will see who is not pleasing to the eye, put the aircraft carrier to show it, now, Germany shows a more intuitive, bloody scene, Germany's huge fleet, is invincible, today is Greenland, tomorrow is Canada, the day after tomorrow is the United States mainland!

Who could stop the German cross-sea landing? This formation is so powerful that everyone will be in awe when they see it, Germany is invincible!

The radio waves traveled all over the world, and also to the United States.

(The TV signal is medium wave, it seems that it must be transmitted through the relay, but I didn't find the information after looking for a long time, in the era of no satellites, how the TV signal between Europe and the United States is transmitted, everyone should be able to spread it.) ）

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, like locusts, are not over at all, those helicopters, strike at the beach in advance, those naval guns, make everyone tremble in their hearts, the mainland of the United States, can it block this kind of fierce offensive?

The Germans were not afraid to reveal their secrets, and this was almost a complete display, and the German cross-sea landing was roughly like this.

This is a show of their force, a demonstration to the United States, and their landing in the United States across the sea is also quite easy!

Now, in the video, with the landing ship directly seizing the beach and the tank moving, it is conceivable that the next step is to easily capture the prisoners.

"The Germans are putting pressure on us, trying to use this tactic to undermine our confidence and even force us to surrender." Roosevelt said: "The Germans are wishful thinking, we will never give in, and now that the Germans have shown their means, we will fight them-for-tat and use special tactics to fight them." ”

Roosevelt never lost faith that each of the three giants of the Allies in World War II had perseverance.

Now, Roosevelt was not afraid of the Germans' display of great strength, and he believed that all this could be cracked.

"Yes, Mr. President." Arnold spoke: "The Germans exposed their tactics in advance, which created an opportunity for our counterattack, and the reason why they can land so blatantly now is a big premise, they completely occupy air supremacy." ”

Without air supremacy, there can be no sea supremacy, and the facts have gradually shown this.

If you continue to send a large number of fighters, then the opponent's battleships will not be able to get so close to the coastline, and your own dive bombers will break through their defenses and bring them death, and at the same time, those landing ships will not be able to land on the beach, and a large number of fighters will sink them.

It is also impossible for those helicopters to run around and attack the ground, in short, as long as there is air supremacy, there is no fear of anything!

When Germany really comes to land on the United States across the sea, the United States will not hide any strength, and thousands of fighters will let the German fleet know what the Great Wall in the air is!

After Arnold's words, the people present nodded, and even the navy agreed, if there were enough fighters, the landing operation of the navy would definitely not be so easy.

"So, now we're going to continue to speed things up, build more fighters, train more pilots." Arnold continued: "At the same time, we also need to focus on the creation of new aircraft, and there are signs that the Germans have begun to develop the first generation of jet fighters. ”

Secrets cannot be hidden, and although the Germans tried to keep the secrets of their jets as much as possible, the use of them in combat several times had brought the attention of the American intelligence system to the fact that the aircraft did not need a propeller and was at the same time very fast.

Jets? Roosevelt was too resourceful to know every weapon, and when he heard Arnold talk about jets, Roosevelt was also a layman.

"Now, the speed of the fighter 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 is like a wall, will break the propeller, if you want to continue to increase the speed of the aircraft, you have to change the power system, jet backwards, the plane flies forward." "It's like a balloon flying forward with your hand loosened, that's how jets work," Arnold said. ”

In fact, the theory of jets has been more than ten years, as early as the 30s, the British began to develop, but the progress has been very slow, it is not taken seriously, until the 43 years of history, stimulated by the German jet, Britain began to accelerate the development.

At the same time, the start of jet engines in the United States is even later, especially since the United States does not have any technical pre-research, and the main jet engines are almost all from the United Kingdom.

Now, with Britain already in exile and most of Britain's talent being accepted by Germany, it is not easy for the United States to start the development of jet aircraft!

Hearing Arnold's words, Roosevelt immediately realized the crux of the technical problem: "Do we have the talent for this?" Do we have the technical foundation? ”

Now, the United States is not afraid of investment, it is afraid that it does not have any technology, and now, what they need is time.

Hearing Roosevelt's words, Arnold also shook his hands, where did he know so much!

So all eyes turned to Hoover, who was responsible for housing the exiles from England, hoping that he would understand.

Sure enough, Hoover's eyes rolled and he said: "If we talk about jets, Sir Frank Whittle is the leader, but after the fall of Britain, we lost news of him, but there are other people who came to us in the United States, such as Hayne Constance, who is also very interested in jet engines, and we can contact him." ”

This is the heritage of the old capitalist countries, there are rich talent reserves, Dr. A-A-Griffith of the University of Liverpool in the United Kingdom once published a paper called "Aerodynamic Theory of Turbine Design", the idea of gas turbine as an aircraft power plant was first clearly proposed, and at the same time, he also conceived an axial gas turboprop propulsion device with a complete compressor and turbine structure in the article.

His research then inspired his colleague Hein Constant, who took Griffith's theories to the well-known gas turbine manufacturer Metropolis-Vickers to design the new aircraft engine.

It's a pity that the plan has just begun, the war has begun, and with the help of the American Embassy, Hein-Konstenter got rid of the surveillance of the German Gestapo and came to the United States, and now it seems that there is no livelihood.

Just get him here to lead the research of jet engines, and at the same time, the development of the whole machine must be launched immediately!

Germany cannot be left behind in the jet project!

"Mr. President, we're going bankrupt." When Hoover accepted the assignment and submitted another scientific research funding, U.S. Treasury Secretary Morgenthau said to Roosevelt with a sad face.
