If you put it that way, the F 404 is from the 1970s,India is also using it,
I'm just surprised the Indians are so greedy, even Korea didn't get the license to make the F 414, India fantasizes about getting 100% of his technology transfer,
The aero-engine is the jewel of every country's industry, and it will not be transferred unless it is the closest ally
Greed or influence?
The US considers India important enough, more so than Korea or Sweden. Plus the deal will be for hundreds of engines, at least 500 engines in total.
Furthermore, they are interested in helping India develop a next gen engine, and the intellectual property and technology of the new engine will belong to India in its entirety, it's for AMCA. Both contracts are being studied by the US govt for clearance. UK and France are competing for the second project.
