Metals that go into the al31 engine are produced here in india by midhani, we might not know the know why but we know the know how, we can make a al31 engine here in india even if russia decides to sanction us.
what foreign component does uttam use, because as far as i know only early prototype (GaAs ones) used some critical foreign content, signal processors to be exact which is now replaced with indigenious one in the GaN based production variant.
As of now uttam is 95% indigenous hardware wise and 90% indigenious value wise.
If you are making a claim atleast have the decency to provide some credible proof to back your claim
India develops AESA radar to make IAF fighters more lethalProject director D Seshagiri of Electronics and Radar Development Establishment (LRDE) confirmed this and said that the developed AESA radar is 95% indigenous, with only one imported subsystem.www.hindustantimes.com
indian irst program is not very publicin nature and there is very low amount of news regarding the program, i don't know how did you came to the conclusion that
irst has foreign content there is no news that denies or proves this allegation,
Even for the AL-31 until you make them you can never be sure
Until you mass produce AESA radars in multitude of systems (aircraft, air defense radars) you cannot claim anything
Keep in mind India has imported aircraft of less demanding technical requirements - Hawk-132 etc
Technically Tejas is an operational aircraft. Isn't it ?
