The gap between PAF and IAF was
greatest of history in 2001-02 stand-off.....and IAF couldn't launch even a surgical strike inside Pakistan territory back then.
After that, Gap has only been decreasing and this trend would continue in coming future, Inshallah
In 2008, premiere IAF fighter, a fully armed Su-30MKI, entered Pakistani Air Space during high tensions....only to be
locked-on by our F-16s and later, our 7 fighter jets "escorted" India's most lethal plane back to the border
After that, IAF never even dared to enter Pak's airspace during that tense time...let alone going forward with a surgical strike...let alone thinking about an open air-conflict with PAF....
In ALL previous engagements, where IAF and PAF engaged each other in shooting war, PAF was able to shoot down way more IAF aircrafts than vice versa.
See this thread started by a well-informed senior Indian member itself...
