BEIJING (Kyodo) -- China's Air Force has refused to accept 16 J-11B fighters manufactured by a domestic aircraft maker due to technical problems, the Kanwa Defense Review magazine said in its June issue, quoting a Western intelligence source in Beijing.
China is believed to have developed the new fighter based on technology from the Russian fighter Sukhoi Su-27, sparking speculation that the maker, Shenyang Aircraft Corp., may have failed to employ Russian technology accurately.
Shenyang Aircraft, based in Liaoning Province, manufactured 16 J-11B fighters in 2009.
"When the Air Force was checking them up for delivery, J-11B had abnormal vibration after taking off," the magazine quoted the source as saying. "As a result, the Air Force refused to accept the aircraft."
A Chinese military source said the J-11B was not chosen for exhibition at the National Day military parade in October last year due to doubts over technical feature of the fighter, according to the magazine.
