How could Russian Military Industrial Complex die out? India was a launch customer for the Su-30s. The single largest defense contract in the late 90s with over 272 total purchased. The Indian contract later on helped win several more customers in Indonesia, Malaysia, Vietnam, Algeria, Venezuela. Indian money helped maturation of the Su-30MKI model and to an extent also funded the further development of Su-34, and Su-35s. Indian money is currently helping the development of the PakFa 5 gen fighter. Indian money helped Migs and Sukhoi survive financial bankruptcy through the bad years 90s and early 2000 via several large scale modernization and upgrade program of India's Mig 21s, 27s, 29s not to mention the large contract and development of naval Mig-29K, Mig 29SMT. When was the last time the Mig won a major export contract?
And then the big and small contracts of Mi-17 helicopters, Kamovs, IL-78s refuellers, AWACs and upgrade of Tu-146 and IL-38s, medium transport jet over a couple thousand T-90 tanks and T-72 upgrades.
Even Russian ship building industry has been surviving entirely on Indian money with Admiral Gorshkov deal, Krivak class stealth frigates, Nerpa/Akula subs.....
Does Iran or Syria buy aircraft carriers or nuclear subs?
And “collorabration “(sic) with China? What “collorabration “? China, all they did was buy a few Russian fighters and copy them and they are now export competitors of Russia.
