Chinese invisible fighter was vulnerable to Russian Su-30 fighters.

The newest Chinese 5-generation fighter proved vulnerable even to 4 ++ generation fighters, in particular, according to data provided by the Indian media, in January 2018, during exercises involving Chinese fighters Chengdu J-20, which, according to Chinese data aircraft manufacturers, created with the use of stealth technology, Su-30MKI fighters, which are in service with India, could unrestrictedly recognize these aircraft.

"The Sukhoi radars see them (fighter Chengdu J-20 - ed.). New Chinese aircraft are not so invisible. They do not require any special technologies to detect them, and J-20 are recognized by conventional radar systems, "the statement of the commander of the Air Force of India follows.

There have been no official comments from the PRC on this issue, but earlier in a special interview, the head of the Ministry of Defense of the PRC stated that modern Chinese fighters of the 5 generation, thanks to the use of the unique stealth technology, the Chengdu J -20 can compare with the Russian fighter Su-57 and the American F-35.

"China has really made great progress in developing its fighters, however, considering the small experience, the emergence of an aircraft created with the use of stealth technology already at the very beginning caused great doubts. It is likely that the vulnerability of Chinese fighters 5-th generation refers exclusively to weapons systems created in Russia, since the Pentagon had previously claimed that the serious advantage of Chinese aircraft is their low visibility ", - the expert Avia.pro comments on this news.
