Sanctions, that's why iaf needed 180 m2k, now possibility of sanctions are low, and amca not a replacement of mmrca, but mk2 can replace mmrca,mrfa. Mrfa is safe plan, if mk2 r&d not going as planned, & importantly keeping sqn strength and to counter chinese advanced jets.The IAF got 36 rafales they want 114 more . That's 150 right there . So a 30 reduction from their eventual end goal .
Let's see .. all indications seem like a new competition for MRFA is not possible .. if mmrca was anything to go by AMCA might be ready by the time price negotiations end
At the end goi buys 2 or 4 sqn off-the-shelf rafale[f4/f5], rest filled by mk2. or maybe goi dilute 110kn jv with 4 sqn of rafale+[additional cost|
