India has been building the SU-30 under license for about a decade or so. So, as long as the Ukrainian equipment, if any, is going to a foreign agency as opposed to a Russian one, I think production will continue. After all, the Ukrainian arms industry too needs to survive.
I didn’t know that Israel is going to buy for the IDF this plane. I think the J35 is a waste of a billion per plane, they can’t even mount a machine gun on it.
