Prospective replacements
Mig 21 - LCA
Miraj 2000, Jaguars, Mig 27 - su 30, AMCA, Rafale
Mig 29 - AMCA
SU-30 came with new category with air superiority and ground attack means Multi role fighter like all rounder. FGFA will also be of new category. they are no replacements but replacements like 1000 v/s 100. means su 30 is many time better than the Jaguars or of Mig 27.
the Junk Yard fleet are of Mig-21, Mig-27, and Jaguars. these are required to be changed immediately no need upgrade of it. second for air superiority as mig 29 is upgraded needs some su 30 of fgfa specially for this with high AESA Raddars with longest range and also long range missiles. The future of such plane for replacing mig-29 shall have capacity of stelath, fly at hypersonic speed, fly at highest level like mig -25, so save against missiles, with high graded missiles and AESA etc. with long range for advance air superiority. The air superiority must possess quality to destroy enemy planes of any grade. with hyper visibility of infrared of stealths. might be FGFA like fighter shall have such capacity.
there shall be change in LCA one by one if it reach upto mark-3 stealthy great else look at russian mig series stealth plane.
Prospective future
su 30 - 250+
AMCA - 200+(guess)
FGFA - 200+
LCA - 200+
Rafale - 200+
so 1000+ fleet will be in future.
