Original plan of PAF from sanctions time was to acquire 250 of total jF17.How many of the III will PAF go for? Is the entire fleet going to be replaced or modified?
However, with AZM project coming along, number of 250 may be slashed or may be not.
Older airframes are already being upgraded, it has been reported in past that blk1 avionics had been upgraded during production of blk2. Last year there was a complete overhaul of blk1, most likely they have upgraded more than software.
On the flip side, PAF may not need all of the jF-17 upgraded with cutting edge technology.
