If you can, you can dig deeper into the relevant information (there is very little information available in terms of data links).
Fifth-generation fighters place very high demands on data communication systems. NATO's latest data link, Link-22, cannot be fully satisfied, and its core data processing functions are still independently controlled by the United States and are not shared with other NATO countries through Link-22.
At present, all countries in the world equipped with F35 are directly responsible for the data processing function of the US military, and these countries do not have the ability to process data. To put it simply, they are just paying for the US military to station the F35, and they do not have control over the F35.
As for the Link-16 of the last century and the Link-17 of the PAF, it is impossible to support the fifth-generation fighter. At best, it can only achieve simple communication, and it is powerless to deal with the massive data communication and information processing capabilities of the fifth-generation fighter.
If you thought the Link-17 was very advanced, it was probably many years ago.
I made an analogy before that a fifth-generation fighter is like a 5G smartphone. You can certainly use it in a 3G/4G network, but when you use it in a 5G environment, it's going to be another world. It's like you're using the same 5G smartphone in China and Pakistan, it's a completely two-world experience.
