The J-20 is the most popular aircraft model in China. In addition to Chinese people being proud of it, Western countries are also very concerned about this fighter. Americans are even afraid after studying it. Frankly speaking: there is one indicator that is the only one in the world. , that is the transoceanic supersonic cruise capability. Even the F22 does not have this performance. It seems that this is the real combat power of the J-20.

In the world today, only China, the United States and Russia have successfully developed the fifth-generation aircraft , and the only models that have entered active service are the F22, F35, J-20 and Su-57, although many countries have also proposed their own fifth-generation aircraft plans. , but it either stays at the level of concept aircraft, or the models developed simply cannot meet the standards of fifth-generation aircraft. After all, stealth performance is a very important indicator of the J-20, but in addition to stealth capabilities, fifth-generation aircraft also have super strong momentum. Perceptual capabilities, super maneuverability and other indicators, and supersonic cruise capabilities are also judged to be an important indicator for evaluating the capabilities of fifth-generation aircraft.

It is worth mentioning that the F22 also has the supersonic cruise capability. It can maintain a flight at supersonic speed for more than 40 minutes. For fifth-generation aircraft, this ability is a bonus, but it is not necessary. , after all, the F35 and Su-57 do not have this capability, but it cannot be denied that they are not fifth-generation aircraft. In addition to fifth-generation aircraft, some fourth-generation aircraft actually also have supersonic cruise capabilities, such as Typhoon and Rafale fighter , but they Its speed is relatively slow and has just broken through the speed of sound. It cannot maintain the high-speed flight capability of Mach 1.8 without using afterburner like the F22.
So why do fighter aircraft need supersonic cruise capabilities? First of all, the battlefield situation is changing rapidly, and even a gap of a few seconds may cause the outcome of the battle to be reversed. The supersonic cruise capability can ensure that fighters enter the battlefield more quickly, thereby reversing the situation. Secondly, although fifth-generation aircraft are compared to Fourth-generation aircraft have obvious advantages, but due to their stealth requirements, they are destined to only use internal bomb bays to carry weapons. They cannot be covered with missiles like fourth-generation aircraft. Once the missiles in the internal bomb bay are exhausted, they need to be deployed as soon as possible. Away from the battlefield, the fifth-generation aircraft has almost no counterattack capability at this time, and the supersonic cruise capability can ensure that it cannot be bitten by enemy fighters.

The birth of the J-20 is essentially aimed at the F22. Not only does it have to overwhelm you in terms of performance, it also has to be comprehensively better than the F22 in terms of functionality, so the J-20 naturally also has supersonic cruise capabilities. , if it is replaced with the turbofan 15 engine customized for it, its mobility will be further improved. As the fifth-generation aircraft with the largest body size in the world, the design of the J-20 will not only allow it to have a larger The size of the internal bomb bay and the fuel capacity have also been greatly increased. Therefore, unlike the short-legged F22, it is really possible for the J-20 to achieve transoceanic supersonic cruise flight.
At present, the U.S. military F22 fighter has begun to enter the retirement process. After all, the concept when this fighter was designed can no longer keep up with the needs of modern warfare. In addition, the fifth-generation aircraft of China and Russia have entered service one after another, and the advantages of the F22 have begun to increase. The United States needs to free up more space for the F35 and provide funds for the research and development of next-generation fighter aircraft. Naturally, some F22s need to be phased out. Coupled with long-term high-pressure use, the integrity rate of the F22 is very low, and the number of fighters that can be put into use is only Half, while the Chinese J-20 is in its prime and has room for further improvement. No wonder the appearance of this fighter aircraft will make the United States very nervous.
