China has rejected the claims about J-20 stealth fighter as Imitate Technology

China has rejected the claim that stealth fighter J-20 is based upon stolen technology. Chinese defense official and military experts persisted that country J-20 stealth fighter jet which was test flown earlier this month is the result of country’s itself own struggles. US Defense Secretary Robert Gates was on the official tour to China, when the flown test of J-20 stealth fighter jet was carried out at Chengdu, Sichuan Province.

Chinese Ministry of National told the daily that it was not the first time when the western media has blamed to prove Chinese military technologies as imitated or stolen. We can’t consider giving remarks on such types of rumors.

The remarks came after when an Indian based American citizen, a former B-2 stealth bomber engineer, was punished by a US federal judge to 32 years of detention for exposing military secrets to China. He was offender of assisting China designing its stealth cruise missile. Also a Croatian admiral accused that China built up the technology for its J-20 jet from F-117 Nighthawk stealth fighter.

Chinese Test Pilot Xu Yongling said that the J-20 has a superior supersonic cruise quality and commanding air mobility that is technological penetrates for our country. As compared to the J-7 and J-8, J-20 is the excellent development of China’s innovation, and is much developed than stealth jet of US Air Force's F-22 Raptor and Russia's Sukhoi T-50.

Xu said it would have not been possible for China to collect technology from US F-117, whose stealth technology is considered as “obsolete” even it was reportedly shot down and due to very complicated production process it is impossible to copy that technology from its parts.

Wang Yanan, an associate editor in chief at Aerospace information journal, said that the F-117 could barely have motivated the growth of the J-20, due to the different designs between the two generations of fighters.
