After first flight for a 5th gen fighter it takes minimum 10 years for FOC induction with all sorts of certifications and validations.
If war happens tomorrow IAF does good chance with Rafale vs J-20 thanks to Meteor or Spectra. We dont know for sure as Chinese MIC mature more specially according to West whlith hure advancements our chance is getter darker.
We need leaner and meaner force, to balance the power. May not have 1000s like China but few 100s of combined ultra modern can be indestructable deterrent
Spectra the cure all magic power for Indian def Enthusiasts.
Lmao spectra is a great EW suit but it won't make rafale a stealth killer of some sort.
J20 will still have almost the same advantage over rafales that they enjoy over other 4.5 gen.
Passive stealth of Rafale is great but it can't make it invisible.
J20 is 10 to 1000 times more stealthy than rafale has more powerful engine has a better more powerful radar and a decent BVR missile perhaps the missile is the only thing in which rafale has edge over j20.
Rafale has less than half of the T/R modules compared to j20 they both claim having 3rd gen AESA(at least Chinese do, not sure about rafales).
