. I wonder whether it can play a air superiority role and take on 5th generation jets given it's reduced RCS?
Can be used based on case by case basis and there are tactics that can be utilized but It will be at high disadvantage when taking on stealth jets.
Stealth loyal wingmans can help somewhat.
How do you see it's prospects against JF-17, F-16, J-10 in Porki inventory?
Can take on anything except 5th gen in most cases.
Though also depends on how our overall integrated system comprising of many air ,ground & space based assests perform, fighter jets will only be part of a larger system, a very important part but again a part nothenless.
If only MK2 is left with us, what do you think our strategy should be?
There are lots of ways and lots of compromises can be made.
Some examples,Just for general gist.
Don't fight head on against incoming enemy airforce, accept that they have advantage.
Find other means of penetrating and hitting enemy ground assets, find ways to attack their fleet when its on ground, develop lot more standoff munitions, cheaper mass producable standoff munition.
Drones are already here, changed warfare forever.
re-settle your fleet into more dispersed, into mountain bunkers etc make it harder to destroy as enemy assets will penetrate air defense, for example Iran operates a deep mountain buried airbase, and only the most potent anti bunker weapons can hope to damage it, it does limit air operations a lot but it makes their airbase survivable against a superior enemy.
Develop more human element based assymteric capabilities, SF.
Etc.
You can learn a lot from russian in this regard, which has a large potent airforce but still outclassed by enemy's firepower.
They have 2+ decades of experience in this.
Their new oreshnik missile, is a asymmetric weapon to compensate having a weaker airforce.
Oreshnik is mainly developed against air bases, a single missile can disable an airbase for hours, 5-6 for few days, and given its flight profile, altitude and speed, very hard to intercept, its meant to limited/decrease the no. Of assests nato can put in the air.
You can also learn from Ukrainians, remember recent operation spider web?
None of this will fully compensate for things we lack, but will make us lot more capable in other ways.
