I too love to have twin engine and Fighter like SU-35 will be great addition and SU-35 can counter Rafal too. But problem is As soon as we buy Su-35 USA will impose sanctions on Pakistan …. One more thing SU-35 will cost us way more then J-10 or any single engine bird.
Problem we (PAF) face is , we have to retire 200+ old birds ASAP , for that we need a cost effective way which I am afraid does not exist , Any 4+ Medium Category Single Engine modern bird will cot us hell lot of Money , Technology does not come cheap .
We already have one Cost effective way of replacing older F-6s and F-7s with modern tech and Gen and that is JF-17 , but JF-17 is light bird .
Now we need medium bird to replace 120+ Mirages …………. At max we have 5 years and any induction started now will take 6+ years (if we buy 20 J-10 per years that will take 6 years to reach 120 mark)………
We do have option , we do have time , some how we can arrange money too , But million dollar question is Do we have will???? Do we want to come out of love saga of F-16s????
