I think this time DRDO & ADA will not delay the development as it is their 3rd fighter jet project and Indian fighter jet developers are gradually maturing now. & for your information, I want to inform you that AMCA's developmental work has restarted again after HAL informs DRDO that it will roll out two LCA Mk-2 prototypes for flight testing by next year & Govt has given the go ahead to AMCA developers few weeks ago.
HAL is developing more new industrial complexes for the particular developments of AMCA & FGFA as it has to run the development of FGFA, Rafael, AMCA & Tejas Mk-2 together for the next two decades. Govt is also funding more for HAL to further expand its capacity to build large number of different fighters at a single timeframe......it will certainly boost IAF's combat fleet for continuous upgradation.....!!!
