always wondered the same why no version with Kaveri ? May be it’s just a wait for it to mature further. Or it had critical deficiency that rendered it impossible.What I don't get is, if they had a Kaveri engine that was working fine in every way except after-burner, why didn't they just use it to create a whole fleet of subsonic aircraft? You could make a fleet of subsonic bombers carrying cruise missiles, a fleet of refuelling tankers, a fleet of AWACS and ELINT aircraft, a fleet of large tank carrier aircraft, etc all being powered by a non-afterburning Kaveri. And you could do it very cheaply by manufacturing the engines and aircraft in India in very large numbers. It would create hundreds of thousands of jobs, as well as a massive military industrial complex. You could even sell these aircraft to other countries for massive profits.
