Chinese J-31 Stealth fighter.
India isn't getting anything till 2020-2022...
We have 6 to 8 years...
By that time, we'll have hundreds of JF-17s block II, III, etc...F-16s...and then acquisition of J-31 stealth bomber/fighter will completely neutralize any indian acquisition.
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.
