Brother You are correct I would like to add some value to ur post,
1. MMRCA is to replace MiG27/23 and complemneted by jaguar (Which will retire during procurement of MMRCA), MiG29. M2000H
2. AMCA will replace M2000H and MiG29 and complemented by MMRCA.
3. LCA MKI and later version will replace MiG21.
4. FGFA will complement MKI and later it will replace MKI (in 2040s)
your second part hurt me.. How can you blame all to DRDO and ADA for delay??? Do you know when fund was granted for LCA (it was 1991)??? Do you know when first LCA flew (It was 2001)?? Do you know when IOC given (it was 2011)???
Google and tell me one fighter aircraft which was made from scratch and get ready in 20 year of time... You name one , I will quit PDF...
