Posted in AMCA thread but it is about Tejas, so I am replying here...
How would that work? A squadron of MiG-21 is replaced with a squadron with 4 x Mk1A and a trainer or two, building numbers up as more Mk1A's roll off the line?initially There will not be 1:1 replacement of the migs with lca.
bec tejas is far more capable than mig-21
