The J-35 is not as fast as imagined. Please consider the issue of the J-35 from the perspective of China.
China' 6G fighter project has been tested many times. At the normal speed, China will enter the era of 6G fighters in the 2030s, and 5G fighters will gradually stop entering the PLAAF.
Therefore, the window period for the J-35 to join the Chinese Air Force is only about 5 to 7. In such a short period of time, the SAC will inevitably supply the PLAAF with as many J-35s as possible, and then it will be provided other customers.
Moreover, India does not have the ability to obtain 5G fighters quickly, and Pakistan is not in a hurry either. Therefore, I believe that the PAF obtain the J-35 in the 2030s.
