1. Invisible design. From the appearance, most of the lines of the fuselage wings are parallel to each other, the fuselage has no vertical plane, no untreated grooves, and the windshield is also coated. Of course, from this perspective, it does not prove that invisibility must be qualified. We can see another small thing, that is, the dragon wave lens installed in the belly of the fuselage. After carrying a dragon wave lens, the radar reflection cross section of the aircraft can be increased by thousands of times. If the J-20 itself is not stealth, there is no need to hang up, because there is no need to reinvent the wheel for a stealth aircraft that can't be fooled by ground-based early warning air traffic control radar. This can be seen from another fourth-generation machine in China. In previous years, the first flight of FC-3 1 was from Shenyang to Zhuhai, but there was no external lens. ?

2. Long-range strike capability. According to preliminary estimation, the width of the magazine of the J-20 fighter is 2 ~ 2.2m, the length is 4.5 ~ 4.7m, and the depth is 0.6 ~ 0.8m Judging from this size, it can hold half a meter more weapons than the American F22 and F35 fighters. If the JSM anti-ship missile is designed according to the J-20 magazine, the missile length can be easily increased by 0.5 m, and it is not difficult to increase the high-altitude range to 1 1,000 km, and the low-altitude range will not be less than 000 km. Of course, if the range is not increased, the weight of the warhead can be easily increased to 200-300 kg, which is more powerful. In fact, the oversized magazine of the J-20 is also a bright spot that Americans envy, and any one can be stuffed more than the United States. ?

3. Information combat capability. The avionics capability of the J-20 fighter is completely equal to that of the American F35. China has all the advanced avionics of F35. In fact, you can tell how powerful the J-20 is by its appearance. From the photoelectric sensor, we can know that one part is radar and the other part is radar. As we all know, there are two licensed radars used by Xiaolong fighter exhibited at China Air Show, and the data of one air-cooled fighter is as high as 170km, which is almost the same as F35 radar. Moreover, the aperture of this radar is only 600 mm, while the visual observation of the J-20 fighter is more than1m. As we all know, the larger the radar antenna area, the higher the index. Moreover, the J-20 radar adopts liquid cooling technology and the best transceiver unit. In fact, the detection range of radar is several times that of F35 radar. ?
