Of course, the United States would not hand over their latest fighter to the Soviets, and the P-39 was difficult to operate, and it was something that the United States did not look down on, so it was supported by the Soviets, but in the later period, because the German submarines were constantly making trouble at sea, very few supplies could be transported.

The U.S. Navy itself uses the latest fighter developed by the Walter Corporation for the Navy, and at the beginning of its development, it was aimed at the German Navy's F190.

This aircraft uses the high-horsepower Pratt & Whitney R-2800, with a power of 2,000 horsepower, and even when needed, through the additional water injection device, the engine horsepower output can be up to 2,450 horsepower, and the performance is extremely powerful.

At the same time, it is also the fastest fighter in the US Navy, with a top speed of more than 640 kilometers per hour, and its performance is comparable to that of the F190, and in extreme cases, it can soar to more than 700 kilometers per hour.

In history, the U.S. Navy has another outstanding carrier-based aircraft, the F6F Wildcat, but this aircraft is mainly achieved when fighting with the island nation Zero, that is, it is a fighter that attaches importance to medium and low altitudes, and the F4U Corsair is a fighter that attaches importance to high altitudes.

The ceiling of the Corsair is as high as 12,006, which is already the limit of the German bomber flight, and the United States will definitely not let the tragedy above the heads of the Soviets repeat itself on itself, and at the same time, if further optimized, this fighter can fly at an even higher altitude.

If you look at it from the outside, the wing of the inverted Seagull is one of its outstanding features, which allows the landing gear to be shorter, which is convenient for deployment on the aircraft carrier, and also leads to the disadvantage that the landing gear is not easy for pilots to see.

Moreover, if the nose is too long, the forward field of view will be greatly limited. (I really don't understand, how can a fighter with an air-cooled engine have such a long nose as a liquid-cooled engine?) ）

In any case, the equipment of this fighter gave the US Navy a great boost of confidence, as long as they had enough aircraft carriers to engage the Germans in the Atlantic.

"Today is our first day of flying." The captain of the flight group lectured in front: "Everyone knows that the Germans are about to conquer Moscow, and there is not much time left for us, even if the Germans have tens of thousands of warships to move over, we will not be afraid, God will bless our land, we firmly believe that justice will prevail!" ”

"Today is mainly for take-off and landing training, and the squadron leader will fly first."

Wearing a full Navy flight suit, Roy ran into his own fighter, and the moment he started the engine, his heart was also excited with the surging engine.

Anyone who loves flying will not resist the allure of advanced aircraft for him, which is why although later generations made money by opening civil aviation, elite pilots still remained in the fighter unit.

Thus began Roy's era of naval aviation.

Moscow, Institute of Physics and Technology.

With the Germans approaching, many institutions in Moscow began to relocate, moving in the direction of the Ural Mountains, where a large number of industries had gathered, such as the aircraft design bureau, the small arms design bureau in Tula, and more importantly, the tank factories, which had been relocated to the Ural Mountains and began to prepare for production.

The Institute of Physics and Technology, as early as a month ago, began to plan the relocation to the Urals, but their relocation was not as fast as that of the weapons industry.

The reason is simple.

Those weapons manufacturing industries are related to whether they can win this war, even if Moscow is lost, as long as the industry is still there, and can continue to produce all kinds of weapons, then there is still hope for the Soviets, if the industry is gone, unable to make weapons, unarmed soldiers, do they have to bite the Germans with their teeth?

The load of railway transport has reached its maximum, and every day countless trains shuttle through the vast expanse of the Soviet Union, transporting industrial equipment.

And the Institute of Physics and Technology has been dragged to the end.

A middle-aged man stood on the window of the research institute, looking out, and at this time, his heart was full of anxiety.

Igor Vasilyevich Kurchatov, the leader of Soviet nuclear physics research, and it was under his leadership that the first nuclear weapons of the Soviets were created.

Throughout the 30s of the 20th century, nuclear physics was still in its infancy. Historically, in 1932, the German physicist Heisenberg revealed the principle that the nucleus is composed of protons and neutrons, and in 1938, the German scientist Otto Hahn and his assistant Strassmann further discovered on the basis of the experiments of the French scientist Joliot-Curie that when neutrons hit the uranium nucleus, a uranium nucleus can split into two lighter nuclei after absorbing a neutron, and the mass loss occurs in the process, thus releasing huge energy. This is the world-famous nuclear fission reaction.

And now, because of Ciric's crossing, these discoveries have been made in the laboratory years earlier, and at the same time, they have become extremely secretive projects, and the outside world is not aware of any progress in nuclear physics.

However, in this very situation, Kurchatov started from scratch in 1934 and built a proton accelerator in his own research institute. This test gave an important impetus to the construction of the first cyclotron in the Soviet Union.

However, the overall situation turned against him, and a vigorous purge began.

Just two years ago, at a regular meeting of the Academy of Sciences, Kurchatov and one of his colleagues were inexplicably slammed. Officials accused him of squandering state funds on "meaningless" nuclear physics.

If it weren't for the shelter of his teacher, Joffee, he would have been shot.

Just last year, Kurchatov, who continued his research under pressure, released the results of the study of the chain nuclear reaction: nuclear fission can produce enormous energy, which will play an immeasurable role in the development and destruction of the world.

At the beginning of this year, he published a report on the spontaneous fission of uranium, and at the same time wrote to Stalin about the necessity and prospects of studying the atomic nucleus.

It is said that his report was probably approved from above, but with the beginning of the Great Patriotic War, his research was interrupted after a long time without allocating money.

Think about it with your ass and you know, at the height of the tension of the Great Patriotic War, how could the USSR allocate funds for the study of such so-called nuclear weapons, which do not know when it will be realized?

Historically, Kurchatov, during this time period, could only put aside nuclear research and go to the Black Sea Fleet to degauss ships.

At this time, standing in front of the window, Kurchatov was lonely, he did not know that a brand new door had appeared in front of him, and if he stepped over, he would become a person standing at the peak of the scientific community of nuclear physics.
