That included the Shenyang J-22, a twin-engine jet fighter that has been in active service since 1998.
It is equipped with two large internal weapon bays for long-range and air-to-air missiles.
The J-20 also has two small sidebays that can hold short-range air-to-air missiles.

It can reportedly carry more fuel and weapons than the F-22 Raptor.
China actually struggled for years to perfect quality, domestically-produced jet engines for its fighters.
However, in 2022 the WS-15 engine developed for the J-20 reportedly made its maiden flight.

Yet, Boneham said China is unlikely to sell the J-20, at least in the near future.
A similar rationale had been adopted by the U.S. in opting to not export the F-22.
It has routinely been presented at air shows, yet still kept away from onlookers on the ground.

F-22/F-35 DNA?
Beijing was even more brazen in its efforts to glean details about the F-35.
It certainly wouldnt be the first nor the last time that China has liberally borrowed from foreign designs.

Many recent Chinese aircraft have born similarities to U.S. platforms, Boneham continued.
Whether or not the J-20 actually has any F-22 or F-35 DNA may not be the point.
