I am only advancing the idea that a realistic path for Russia to drive down the cost on the SU-57 is to downgrade the electronics. How far down that would drive cost is not something I would even be able to speculateBefore the hiatus of the Russia/India Su-57 affair, Russia had quoted 250 million per copy of the Su-57 to India, I think that was the straw that broke the camels back. This was after FGFA had been rolled way, way back.
It was a number of years ago, and economies were much healthier, lol.
anyway, I would be beyond shocked it the Su-57 comes in much below 80 million, even if the electronics are down graded??
