Honestly we should do a G2G deal seperate from the MMRCA for the Mig 35's. And I know it's stupid but we have atleast 100 mig 29 across the IAF and IN. They need to be AESA equipped. And we can use them as a test bed for further tech until the tejas mk 2 comes online. Though by the time this deal fruitions the mk 2 will come online
The Mig-35 is a waste of money. LCA Mk2 is a better bet even if it comes a bit later. As a brand new design, using unproven Russian tech, it's going to take years before the Mig-35 becomes operationally usable. Which is the reason why the IAF has insisted on only operational aircraft as their 4th gen choice. Even in Russia, it's still in its earlier stages. It's only in LSP stage. It will take until 2024 or more before IOC deliveries begin, and as much as 2026 or more to see it fully operational in Russian service, only after that can we even begin to consider it. The Su-57 Stage 1 is at a much more advanced stage. We basically need 4th gen jets that have been in operation for years before we consider them seriously. No new jets. It's also among the reasons why we are not interested in the F-35, it's not even finished development.
A better bet is to see if there's an option for another 20 unused Mig-29s hidden in Russia somewhere, although I doubt there's any.
