well, this is a very heated thread. i shall say my part and leave it at that. Russia is pushing India to purchase the su-35, by creating the the atmosphere of Pakistan procuring the su-35, which in fact they genuinely want.
quiet a while ago, just after the 126 jet deal was cancelled, sukhoi proposed an more advanced mki variant based on the su-35, this deal was dropped in favour in searching for other western suppliers. quote me if im wrong here, but there were plans to have internal weapons bays. similar to that of the f15-se(as shown in the link).
would i see the su-35 in paf colours? No
does paf need the su-35? yes
