A few years? India will be lucky to have the LCA in production in a few years, nevermind the others.
My dear friend, till now whatever the world saw in India during the 90s, is called the Dark Ages of Indian armed forces. However, despite lack of experience and bureaucratic structure not to forget blatant corruption, we still managed to design and fly a supersonic 4.5th generation combat aircraft without a single crash in its history of flight tests. That is something truly appreaciable from the designers and engineers' side since we have to judge them on the basis of how limited their budget is and how many hassles they face as compared to the cash richer Western and developed countries.
However, I assure you that you will find the military aviation industry in the near future much better and far more enhanced as compared to what you saw till now. Best wishes.
