"Test flight generation, design generation, pre-research generation." Qin Guan said: "In the Western world, the third generation of aircraft has been finalized for service, and they must have also begun intensive pre-research of fourth-generation fighters."

On the third-generation aircraft, Qin Guan could still provide help, but on the fourth-generation aircraft, Qin Guan could not exchange the whole machine. Those fourth-generation aircraft could not appear in the cemetery. In the past, Qin Guan thought that they could not provide Any help, but now, thanks to the weapon data system, Qin Guan can still provide some technical data support, but the main researcher must be its own technical personnel.

Now that the third-generation aircraft is undergoing intensive test flights, the pre-research on the fourth-generation aircraft can actually start temporarily. Of course, it was initially theoretical research, such as basic research on stealth.

"You should know that I participated in the Niu Country Air Show last year and brought a few models. As a result, Grumman was very interested and even used their vacuum titanium alloy welding technology to exchange with us." Qin Guan said.

Eagle Nation's confidentiality is also very strong, such as the F-117 and B-2 bombers, which are all highly confidential projects, and only began to be announced after many years.

Now, the outside world does not know, but some clues can be seen. For example, if Qin Guan used those models to fool, Grumman would be fooled?

On the one hand, Qin Guan's ability is strong, and on the other hand, it also shows the needs of the people of Ying Country.

Hearing what Qin Guan said, everyone nodded: "Yes, it seems that we are also going to conduct pre-research on the next generation of fighters."

Qin Guan mentioned the fourth-generation machine several times before, but no one took it seriously. After all, the pace was too big and it was easy to get involved.

Now that the project of the third-generation machine is progressing smoothly, it is natural to transition to the fourth-generation machine.

While talking, everyone has already arrived in the meeting room. The focus of the meeting was the two design units reporting on the progress of the test flight, but Qin Guan took the lead.

"Since it is a fourth-generation machine, it must be advanced in terms of indicators." Qin Guan said: "If you want to truly meet the fourth-generation machine, then there must be four requirements."

Generally speaking, the technical indicators of advanced fighters are all proposed by the Eagle State. The Eagle State Air Force proposes the next-generation fighter indicators according to its own needs. Then, various aircraft companies bid for the final generation of advanced fighters. .

After seeing the Eagle Nation's fighters, Xiong State would follow suit and set up a project, surpassing each other in all indicators, trying to suppress it.

But as a result, Xiong’s fighters lag behind in time. For example, when the Eagle’s F-15 came out, Xiong began to plan the Su-27 and suppressed it in all aspects. However, the design of the Su-27 has gone through nearly ten years. During this period of time, all countries were forced to use MiG-23s to fight F-15s, which was abused due to generational differences.

After Su-27 came out, the Eagle Country had already started to engage in F-22, and continued to fight.

In the old days, Han Guo couldn't even think about it, it was impossible to catch up, and it was impossible to go forward together, or even overtake. For more than ten years, even the technology of the MiG 21 has not been fully understood. How to talk about overtaking?

Now, everyone's J-11 is flying for a test flight, and the progress of the J-10 is also getting good news, so everyone has the confidence.

Now, Qin Guan mentioned the fourth-generation machine, which once again attracted the attention of everyone.

"First of all, the first point is that everyone can see the characteristics of my Grumman aircraft model. It has angular, diamond-shaped nose and a special fuselage. It seems that they don’t understand aerodynamics. This design is for stealth." Qin Guan said: "The first goal of our next-generation fighters is stealth."

"You may already have an impression, or many comrades do not have this awareness. In short, with the development of our technology, you can see that under the control of airborne radar, the combat style of long-range missile launches will become more and more common. If our plane can hide in front of the radar, the enemy will become blind."

"Invisible? How is this possible?" Someone immediately retorted: "Isn't that a science fiction?"

"Yes, we have to make our technology sci-fi." Qin Guan said: "Complete stealth is impossible, but if we change the shape of our fuselage, let its radar reflection area and a The pilot’s helmet is about the same size. In this way, the other party could find us at a distance of 100 kilometers before, but now it can only be found at a distance of 5 kilometers. Isn’t this stealth?"

"Impossible, how is this possible?" Some people still do not believe it.

"You may not know that our navy already has a stealth missile boat." Qin Guan knows that it is difficult for everyone to change their minds.

How hard is it? Even in the 1990s, there are still many people in the Air Force expecting to fill the quality gap in quantity. If there is a war, they will rely on a large number of J-7 and J-6 fighters to fight the enemy, win by more, and rush into the enemy’s air. Fight bayonet.

The results of it? The Gulf War awakened them. In the Eight Years’ War, the powerful Date Palms Air Force, faced with the air power of the Eagle Nation, had an extravagant hope for launching. They were discovered as long as they took off, and they were shot down as soon as they took off. At this time, the Han Guo Air Force was completely awakened.

The difference in quality cannot be made up by quantity. The truth that backwardness will be beaten has never changed. After all, the strength of the Han National Air Force was far inferior to that of the Date National Air Force.

Now, there are stubborn forces in the Air Force, and Qin Guan wants to persuade them. Fortunately, Qin Guan's prestige is sufficient now, and the senior officials in the Air Force know how to change.

"You can go and take a look. This missile boat has a displacement of about several hundred tons. However, the sea search radar of a warship on the water can't find it at all, because its radar reflection area is about the same as a rubber boat. "

Qin Guan said here, the quick-brained people have already reacted, if the surface warship's radar cannot detect the missile boat, then the missile boat can launch an attack calmly!

Similarly, in the air, if the fighter plane cannot be detected by the opponent’s radar, it can be attacked calmly. You must know that the opponent only uses the radar to discover itself when it is five kilometers away. It may be seen with the naked eye from thirty kilometers, but One can launch long-range missiles within 50 kilometers.

This is the technical advantage, whoever has the advantage will be invincible!

Qin watched the expressions on everyone's faces and continued: "The navy knows that there is a change. Should the heads of our Air Force stubbornly stick to the original concept?"

Everyone who said this was shocked.
