Su30MKI is Russian as long as it has Russian Avionics the day India replaces the avionics with Indian one it would become an Indian fighter jet and to integrate Meteor with UTTAM AESA Radar MBDA would be sharing source codes with India not with RussiaI do think both MBDA and European governments would 100% object to Meteor integration onto Su-30 MKI.
India doesn't integrate the missiles, the manufacturers of both the missile and the fighters do it together.
Definitely not. Look at how long it took China to even get close to western engines, even with the WS-15 I doubt they will reach the performance of the F135. To even reach F404 levels of performance I believe it will take about 10-15 years for India.
As in my answer above, with Dassault and the French government's permission, DRDO and Dassault will jointly integrate Astra missiles on the Rafale
Maybe a budget Meteor, both in cost and performance.
Manufacturers of the Radar and Missile do it together by sharing source codes but India integrated Israeli Missile with Russian Radar without Israel and Russia sharing source codes with each other
I agree with this point but India has already developed an engine called Kaveri which produces 73KN of stable wet thrust
But you said Europe can't share source code with India how will they integrate an Indian Missile with an European Radar without sharing the source codes ?
The specs of Astra MK3 are superior to meteor but only time will tell whether it's superior or not
