When Russia is ready to provide su 35, China ready to provide j10b,c what is the fun of building 250 thunders. These jets are more sophisticated, carry more pay load, better radars, sensors and are versatile then jf17. Yes These jets literally cost double than jf17 in fly away and operating costs but These are far superior and logical options in present threat scenario than a jet described by one PAF pilot as 'poor mans F16' . PAF needs a long term strategy for the said purpose keeping in view limited resources.
