Key to Tejas-Mk2, AMCA-Mk-1, and Mk-2 long term will be the high thrust domestic engine (120-130KN) being developed with safran...If the JV can start producing this engine (post testing and certification) before 2035, then all AMCA's (especially Mk-2s) can have this engine and thus supercruise and the cooling to increase full spectrum stealth...India should also start thinking about 6th gen (at least start a project to plan) either by joining the GCAP (UK+Japan+Italy) or launch one domestically (formally by 2030) so we can field a fighter in the 2040-2045 timeframe, buth key again will be variable cycle engines (like the ones for NGAD) with high thrusts of 200KN...Long term Defense-Industrial roadmap, while transforming R&D via DRDO, Labs, private players and an innovation ecosystem is vital.
