The first test-flight of the Tejas Mark-II version, with more powerful American GE F-414 engines, will be possible only by December 2014, with its production beginning in June 2016. And even then, the Tejas will just be a medium to low-end fighter, not a high-end air dominance one. , The Times of India quotes the Union Defense Minister A.K. Antony that the Tejas has just reached semi-final stage The overall developmental cost of the Tejas project, including the naval variant and trainer, has zoomed up to Rs 17,269 crore from the initial Rs 560 crore earmarked for it in 1983. With each Tejas to cost around Rs 200 crore over and above this, India will end up spending well over Rs 25,000 crore on the programme.
Lets design Tejas first then think about the great on paper designs like AMCA
