The principle Support, where PAF brought J17 almost zero subsystems. No FBW, No BVR/WVR missile, no EWS, I doubt even without Radar. Though UNAF also do the same but ONLY for import weapons.
So according to you, All air forces around the world is suffering from Malnutrition as none operate like IAF.
Was Tejas was not intended to achieve FOC ?? Or IAF was unaware about term FOC?? How can you compare anything with unfinished product ?
If we apply your logic even F-35 is inferior to mig-21 because it wasn't carrying internal cannon in 2010 or some of even today (Gun pod)
"Dadi ko nakli muchh laga Dene se vo dada nhi ban jata". Mig-21 is a second generation jet and do not have effective BVR capability. If you believe then call Hawk trainer also a bomber as they can carry bombs.
See, You Import fanboys often don't understand how UN armed forces place impossible GSQR and Never involve in project ab initio and take decades of trials. which effectively make upcoming product nonviable. Don't forget Rafale yet to be upgraded.
"The Desperation" of Import fanboys to excel their argument where it is impossible to even negotiate.
If Tejas is improving so did Mig-21 and so do others it doesn't mean it is inferior.
By the Way, How Mig-21's FBW is working??
No doubt Tejas is not sufficient but adequate for its role, performance and well fit into IAF's healthy combination.
