6th generation is still a few decades (2-3) away. I def dont consider the British Tempest or Japanese F-xx fighters to be 6th generation as they claimed but 5th generation.Pakistan air force project AZM will be a chinese jet with Pakistani input and possible Pakistani chosen avionics, missiles systems if available.
We are still waiting for Chinese military to decide which 2nd 5th generation fighter jet they will they be producing, we will follow the Jf17 route which is highly successful project for Pakistan. Project AZM will also be successful InshaAllah, just the delay is killing us. We should have introduced 5th generation by 2025 but now even 2030 looks too early, by 2035 the world powers will be introducing 6th generation whilst we be introducing 5th. So always a generation behind the world powers.
5th generation jets are the last manned jets...truth 6th generation jet will be unmanned and make use of artificial intelligence & machine learning.
