Just saying, i am still confident in that we will see a block 4 JF-17, i have been saying so since 2021 and still believe as such, lets look at it logically:
It's pretty clear that the PAF is seeking further indigenization of the JF-17, Block 3 received home-grown EW systems designed from scratch alongside SDR's, the same team designing these systems was also in charge of the fighter radar. AFAIK, they were moved from the radar onto these projects so i assume that would have meant the radar program was shelved, but i don't think that was the end of that.
Aside from that, it will be very expensive for the PAF to let AMF run idle, so either they will continue to order block 3's or a new iteration as a whole before AMF transitions to NGFA production.
Alongside this, its pretty clear the JF-17 has yet not reached the level that the PAF envisioned, uprated engine, IRST, more diverse weapons etc. While none of this sounds significant, this is all summarised, i have pretty strong reason to believe we will see a block IV.
The PAF will keep the production line running, using Block 3's to fill it until the funds are available and development is complete. Currently, funds are low, hence the block 3 order was cut and the production rate has been lowered to keep the line from idling, once funds are there, i anticipate another 20/25 aircraft and then the line will transition to a block IV, domestic AESA, new cockpit, domestic AAM's, improved IEWS, a guess is potentially some more advanced materials as PAC starts to prepare for transitioning to more advanced production processes, new engine, improved national TDL/IFF etc, these will also trickle their way down to MLU JF-17s IMO, i dont think they'll receive KLJ-7A but thats just a guess on my part, i think the PAF will try and standardise the fleet around their own domestic radar and further develop that
lets see what happens
