Finally, someone who voiced this opinion otherwise this forum is full of posts which make one think like developing a 5th gen aircraft is peice of cake while in the same breath ppl mention how we lack skills and finances to evolve jf17 further than block 3. In layman's terms its like jumping off to PHD when you haven't even finished your bachelors yet.
I beleive instead of venturing into 5th gen we should simply buy few squadrons of FC31 off the shelf from China (if and when available). When countries like US, China and Russia are not fully relying on 5th gen and the true backbone of their fleet is going to be 4.5 gen then how come Pakistan go with a full focus on 5th (not to mention the associated price tag).
It would make sense for Pakistan to have thunders together with some decent medium weight 4.5gen aircraft (or thunders evolved further into a medium weight category in parallel with the likes of f16Vs/j10C, strike varients, indigenously developed mission pods, avoinics etc) to compliment the limited fleet of 5th gen forming the spear head.
