How so? You are not getting into a fist fight with a dude....BISON is a BVR firing platform from 70 KM away and the missiles pose a serious threat to whatever jet they are chasing after......and in my example, if 25 missiles are chasing after 25 jets....its serious threat to those 25 jets. What else could be more serious than a capable missile that can bring down a jet?
Supplemented by the SU's, Mig 29's, Mirages and soon Rafale's.....its a massive force to deal with. That is why I keep saying, SOMEONE in the Civilian Gov't and the Military / PAF needs to come up with a real, long term strategy. That is, do a real threat assessment, measure short term, mid term and long term goals, considering Afghanistan will have Indian bases in the next few years, Iran won't be friendly due to Saudi fraction and the IAF / IN will be gaining significant numbers and modernization.
Someone needs to look into heavier platforms, acquire a long range SAM system (build it locally in large numbers) and be looking at some Stealth plane for 2020.
I've been saying it for a long time now......long range SAMS, a few squadrons of -15's or J-11's and then J-31 or watered down JSF (if Pakistan can afford it) are the need of the hour. SAMS are cheaper and all......but you need to realize they can be taken out from well within the enemies' airspace. You need both, modern jets in numbers and in a Hi-Lo mix and then two tiers of long range SAMS (with the third tier being point defense F-7 and short range or mid range SAMS).
