Build new MKIs with the proposed upgrade package. 2-3 more squadrons. Or Order two squadrons of Su-57s with option for license manufacturing. Rafale is the only aircraft that'd win MRFA, requires diplomacy to start local production to meet induction rates, and the French will reasonably demand almost a 100 total orders. Up to GoI to sell this in the parliament using National security and "boost to local economy" angles. Once the GE404 drama is solved, double the Mk1A production rates to at least 30 aircrafts a year. Open additional facilities as needed, these will later be used for Mk2/AMCA/TEDBF lines. Order atleast 350 MK2s to assure HAL for future orders so they speed up production. We simply HAVE to build/induct more or less 2 squadrons every year for the next 10 years. We need to keep up the high Tejas production rates, AND keep two separate lines open for licensed fighters like Rafale and Su-30/57. While simultaneously figuring out how much private sector involvement we want for AMCA and set in stone the workload share. Because by the time Mk2 goes into production, the AMCA production plans better be solid and ready for an empty line. Now for all of these simple goodies I mentioned, there's this not so simple mammoth issue of budget. $5.5 billion a year won't cut it. TEDBF I have honestly no clue, I doubt it's even in active development. IAF is not interested in it, and Navy doesn't get enough budget to think about it deeply right now. If local production of Rafale-Ms are set up, they'll be content with those. More Migs are a bad idea because of their subpar availability rates, and Klimov more or less gave up further developing the RD series engines after the MK. Old Mirages we get from here and there will only be cannibalized for parts.
