In fact, these are all state military secrets. Especially some model parameters developed in recent ten years.
Rumors are flying all over the internet, all of which are the analysis and speculation of some military fans. Most of them are unreliable.
Because these are national defense secrets, it is estimated that the military commanders of large groups may not be able to master them.
We are just babbling aunts.
You can make do with it.
Since China learned that the United States had successfully developed the stealth plane, it began the preliminary development of the stealth plane (note: at that time, the United States had not released the news, which was a top secret military secret).
Due to many reasons, such as capital, technology, equipment, personnel quality and design level, the development of stealth aircraft in China was limited to "talking about aircraft on the map" at that time, but China made great efforts in how to detect stealth aircraft with radar and made great progress. After all, it is much easier to make a radar than an airplane, but China can't find a stealth airplane to test the reliability of the radar.
1999 During the NATO air attack on Yugoslavia, China was eager to test radar. Although the effect was barely achieved, it also achieved the effect of finding and shooting down an F- 1 17 stealth fighter. When the United States learned that China had placed this new radar on the top floor of the embassy in Yugoslavia and the relevant components of F- 1 17 were placed in the basement of the embassy, it ventured to bomb the embassy of China in Yugoslavia and tried to destroy everything about the stealth plane. However, people are inferior to the sky. Because a bomb didn't explode, things didn't go through completely, so that China quickly grasped the real secret of the stealth plane. The result of the behind-the-scenes contest between China and the United States was that China won first, which made China tolerate American aggression. On the surface, China gave in, but in fact, the U.S. Department of Defense flew into a rage and almost canceled the military orders of all bomb manufacturing companies.
Five years later, as soon as China's aircraft manufacturers built stealth aircraft at the fastest speed, the military stopped. There is a simple reason. With the unintentional and intentional help of the United States and Yugoslavia, radar manufacturers in China have produced radars that can easily detect stealth aircraft and established a large-scale radar detection network. After the radar was tried in North Korea, the F- 1 17 of the United States was forced to retire. It is said that America.
China's army has always attached great importance to national air defense. As early as the end of 1990s, the slogan of "new three strikes and three defenses" was put forward, and it was clearly pointed out that "stealth aircraft should be attacked". With the development of 10 years, advanced phased array radar, new anti-aircraft missiles and domestic stealth fighters have become the sharp weapon for China army to fight against stealth fighters. For example, at the World Radar Expo in 2009, a scientific research unit in China confidently demonstrated DWL-002 passive air defense radar, and some critics pointed out that it is the most advanced anti-stealth aircraft radar in the world today. Not long ago, the J-20 stealth fighter let people see the improvement of China's anti-stealth strength from land to sky, and the leap from defense to attack. We can guess optimistically that China's army has a clear idea on how to deal with stealth fighters.
How strong is China's stealth technology? The United States and Russia almost speak in unison: China's stealth technology is not comparable at all, and even agree that China's stealth technology is an imitation. Why on earth don't the United States and Russia believe that China's fourth-generation aircraft belong to independent research and development technology? What's the purpose?
The United States and Russia are the latest countries in the world to develop four generations (Russian fifth generation) fighters. Because the United States claims to be the number one in the world, it naturally doesn't want to be looked down upon by its allies, so the United States simply doesn't want to admit that China can independently develop fighter planes. The traditional American military field likes to regard Russia as a competitor, but the China military doesn't.
With the strength to fight against the United States and Russia, how does the United States usually exaggerate the threat of China in the white paper on national defense, and how terrible China's weapons are, saying that China's weapons research and development belongs to stealing Russian technology, and Russia's T50 is equipped with its own troops? Now, I still let India pay for it, and I am engaged in R&D myself. I also said that if I cooperate with Indian Asan in R&D, can China steal the fourth generation aircraft from Su -27 and Su -30? If it is developed from these models, why are the shapes, engines, stealth technologies and so on different from those of Russia? Even the Russian T50 is different from the China Ribbon. Don't say Russian plane. Are they the same as American planes?
It's not the same. It can be said that China developed itself on the basis of absorbing all advanced achievements. China's weapons have always been compatible with many advanced technologies, which is obviously China's advantage. It's just that America doesn't want to talk about it.
Why doesn't Russia believe that the plane developed by China is not as advanced as him? That's because Russia can sell more weapons for the sake of traditional face, find face in front of third world countries and sell more weapons. Of course, in order to sell more weapons, we will naturally find scientific evidence that China is also stealing, which is also false. China's research and development of new materials in recent years is relatively advanced, and it has been at the forefront of the world. At present, Russia can't develop advanced stealth materials, but China can. Rare earth is an essential material, which is believed to have been used. The latest research on stealth technology is discussed. It is necessary to study plasma stealth technology, which, like a display screen, can change its appearance according to the changes of the surrounding environment. Can Russia study this technology? Look at the development of Russian TV and plasma screen industry to see if Russia has this strength.
In fact, China's own anti-stealth technology has been studied for a long time, even before the fourth generation aircraft. China DWL002 passive detection radar system adopts multi-base station layout, and each base station will capture the signal. By calculating the time difference of signal arrival at each station, the distance difference between the radiation source and each station can be calculated, and then the air coordinates of the target can be obtained. To hone anti-stealth tactics, on the one hand, we can send stealth fighters such as F-22 to participate in joint military exercises like the US military, so that they can engage in high-intensity "air combat" with three generations of fighters, so that their pilots can feel the pressure brought by stealth fighters and seek solutions; On the other hand, stealth bombers or stealth fighters can try to "break through" their own air defense network and find and remedy loopholes at any time. The US military has conducted similar exercises. China's army has always attached great importance to national air defense. As early as the end of 1990s, the slogan of "new three strikes and three defenses" was put forward, and it was clearly pointed out that "stealth aircraft should be attacked".
With the development of 10 years, advanced phased array radar, new anti-aircraft missiles and domestic stealth fighters have become the sharp weapon for China army to fight against stealth fighters. For example, at the World Radar Expo in 2009, a scientific research unit in China confidently demonstrated DWL-002 passive air defense radar, and some critics pointed out that it is the most advanced anti-stealth aircraft radar in the world today. Not long ago, the J-20 stealth fighter let people see the improvement of China's anti-stealth strength from land to sky, and the leap from defense to attack. We can guess optimistically that China's army has a clear idea on how to deal with stealth fighters.
Russian T50 now seems to be a myth in itself, and it is unknown when it will succeed, not to mention that American F_22 has completely stopped production and grounded. This is related to J_20 in China. As a new generation fighter, the J-20 itself has become a model. In contrast, if you can't win, you might as well not make a fool of yourself. It shows that China's stealth technology is simply world-class, because the new generation of fighters are competing for stealth technology, otherwise they will be eliminated, so: Give advice to the Olympic black spots.
