Wrong. HAL's Koraput division fully builds AL-31 from raw materials stage since 2009. Hope you will understand.
Welcome to Engine Division, Koraput of HAL
You see, there are some advantages to license manufacturing and learning, instead of outright stealing and thereby abandoning all future help from the OEM country. This is one such instance. China still has to buy these from Russia, whereas we have eventually developed the core competency to fully build/manufacture it ourselves.
do you have any clue on how an engine is made?
Only 5 UNSC countries can make a working turbofan engine. China currently is the worst of the 5. Nonetheless WS-10 series still count.
India manufactures AF-31?
Even technological giants such as Japan and Germany can’t do it, neither Sweden or Netherlands, etc. India?
HAL’s claim is even more fanciful than India having sent a man to Mars.
if India can make it, then why you can not even make the minimum maintenance of it on you own, instead of shipping it all the way to Russia, huh? Simple logic. The HAL propaganda just doesn’t wash, at least for anyone with more than 2-digit IQ.
Make 90% of an engine is easy! With some billions investment of factories, even Nigeria or Ecuador can do it. The most critical/difficult part is that tiny rest 10%, though. That, like hydrogen bomb, or ICBM with multiple miniature nuclear warheads, is not for sale- even for Russia - has Russia lease that Akula to you with N-missiles in it?
That tiny 10% can take India another 500 years, or for ever, trust me.
