You didn't understand. In my post, I was actually agreeing with what you said. Like you said, the JF-17 has reached it's peak. In order to enhance it further, it will have to be modified heavily. I never said that PAF should redevelop it to J-10c level.
Well, there may be some differences in understanding between us.
Secondly, my question still stands, is it worth investing in a design that has already reached it's peak? It would only make sense to fully localize the JF-17 airframe IF we have plans on producing more but so far we have not seen anything of the sort.
I think the JF-17B3 has really reached the peak of the JF-17. It could still use some minor upgrades, but not too many. For example, using the WS-21 engine, more electrical power would allow the existing avionics to work better.
Based on current PAF requirements and the adversaries Pakistan faces, the JF-17B3 will be in production and service for at least a long time yet.
But it is already a liability for CAC (lots of idle dedicated production systems).
So, it is entirely necessary for PAC to work towards a fully indigenous production airframe for the JF-17B3.
At the same time, by achieving 100% indigenous production of the airframe, PAC can acquire more industrial capabilities and technical talents. This will provide strong support for PAC in the future.
I kind of agree. I believe that Pakistan should start developing local subsystems for these aircraft without modifying the airframe and iterate upon them. In the future whether it’s the J-35 or another aircraft ,we should buy the jets and integrate our own local subsystems and munitions. Meanwhile, we should focus on mass producing UCAVs and develop derivative technologies from the subsystems created for jets to be used in those UCAVs. Over the next 30 to 40 years, this approach will allow us to reach a point where we can start manufacturing our own jets with minimal help from the Chinese or the Turks.
The development and production work on subsystems for modern fighters, especially from 4.5th-Gen onwards, is very demanding. Pakistan does not have the relevant capabilities at all.
For example: the two most central subsystems, the radar and the engine.
You can carefully check how many countries in the world are currently able to manufacture GaN AESA and military turbofan engines completely independently. Those countries that rely on imported core components to assemble them are not included in this scope.
