Du also said that a “revolutionary” breakthrough allowed the twin engines to increase both power and reliability.

China’s inability to manufacture quality jet engines has been a weakness of its aircraft manufacturing programs.

Du also said that the electro-optical targeting system provides better surveillance and strike capabilities against both land and sea targets.

The J-20 also has a larger weapons bay than the U.S. F-22, which allows it to carry more powerful missiles that can be used against “aircraft carrier and foreign AEGIS ships,” Du said.

U.S. officials said the new J-20 had undergone ground tests, but it had not been flight tested as of early March.

Richard Fisher, a specialist on Chinese weapon systems, said the new J-20 was flight tested on March 1 and demonstrated the enhanced fifth generation jet fighter features.

Fisher, with the International Assessment and Strategy Center, said it is “very curious” that the new J-20 featured its new electronic targeting system under its nose. That location increased its field of view and is similar to the targeting system on the F-35.

“This targeting system and a set of distributed high-power infrared sensors give the F-35 a previously unrivaled ‘situational awareness,’ but the now it is clear that the J-20 will have a similar targeting system and its own set of distributed sensors,” Fisher said.

“If as part of their espionage, China had also gained engineering insights into the F-35′s very advanced sensor systems, that could prove disastrous to its combat potential barring a rapid redesign and improvements before entering service,” Fisher added.

Advanced sensors on the F-35 were intended as insurance for the jet not having the best capabilities for maneuvering in flight, he said.

“But if the Chinese, via cyberespionage, have gained insights into its sensor system, then it is to be expected that China is also working on ways to jam or otherwise degrade its advantage,” Fisher said.

The J-20 targeting system indicates that the Chinese plan to use the jet for ground attack and air superiority missions like the F-35, he said, adding that it now appears the J-20 will be comparable to the more capable F-22.

“We can be assured that J-20 production will significantly exceed that of the 187 F-22 fighters cut off by the Obama Administration in 2010,” he said.

China’s Communist Party-affiliated Global Times reported Jan. 20 that China obtained key technologies from the F-35 and incorporated them into the J-20

The newspaper did not admit stealing the technology, but stated that China “completely obtained the six key technologies” from the F-35.
