India doesn't even have their own program at that level, as a matter of fact they are behind Iran when it comes to stealth R&D even if it's a fake.
Honestly, not supporting the guy who made this discussion a troll but saying the above post may be exaggeration.
I would love to know about how many intellectual properties Iran scores every year against India's or how much their R&D budget. How much of made by them is proved to be useful for other countries in world too.
Engine:
The metallurgy, you need to master Nickel based superalloy tech, not that easy.
Stealth Plane:
Preliminary Design phase, developmental design phase, integration with new equipments, a lot. Iranian Stealth plane can't be ready this early.
Regarding testing, you need basic infrastructure for developing, wind tunnels, testing beds.
There's a lot in world tech which is not in sight in case of Iran. Even much of what they claim.
No offense intended to anyone.
Nor I'm a very active member on SD who gives explanation of everything posted here.
Nobody wouldn't have aruged over that either.
