J35 is already at an advanced stage, hence the surprise at J20.Hi,
No---he is not---.
In another 5-10 years---the latest J20 version flying at that time would be the fully integrated and operational advanced air rcraft of the chinese air force and as well as pakistani air force as well.
Most people just simply don't understand and can comprehend how difficult and time consuming the process of integration and pilot training it.
Training a pilot on aesa is making the pilot forget all his experience on the non aesa radar and then make them learn the aesa option and combat---..
Look back and see how long it took the Girppen to be where it is today---. It started in the mid 80's---as did the F22 following it was the F35.
These aircraft took decades to develop into the form that they are in now---ie the machine the pilots the technicians weapons the electronics----2 of these aircrat were those of the richest super power and the Gripen that of an extremely advance in engineering nation.
