Rafale in June 2015 confirmed the existence of the I-Derby-ER that has a range of 100 kms. I believe this is the version that the IAF is planning to integrate onto their SU-30MKI due to the poor performance of the R-77 during the Feb incident last year.
You meant Rafael (the Israeli firm)?
I agree integration is probably much more problematic especially when the Russians are not cooperating. The issue of integration has nothing to do with whether it is an AESA or PESA radar It is about source codes and how the different sub systems such as avionics, GPS, stores management, and sensors integrate with the missile firing system. I have seen the technical explanation on how the IAF plans to integrate an Israeli product onto a Russian system but I can;t possible determine whether it is BS or it will work. I suspect it will be difficult and will slip in time line as most Indian programs do.
I don’t know about the Quad and the long term aspects but ASEAN, India and Japan is highly unlikely to happen, India and Japan combined can’t even remotely impact/replace the ASEAN economic interests involved with China, Japan themselves has a great deal of economic interest to think about too. The only odd one out is India in this relationship, the problem is what can it offer that China can’t, and what can China offer that India can’t.
I think the reason goes beyond that. With evolving time, general people's priorities have shifted from politics/Geo-politics to more basic needs like education,home,life style. What US really seeking is European style solution for china that happened during WW2. They asked US for help. US fired putting gun on it's ally's shoulder. All the devastation had to be faced by the countries involved in direct conflict. US went home happily. Not only WW2, from thereon, in every conflict, US has been desperately trying to keep the conflicts as far as possible from CUS so they can avoid another Kent state saga.
