that is my point - the 5th gen Su-57 doesn't exist. The prototypes flown are with old engines. And in general - India, who really wanted to buy the 5th gen Su-5

that is my point - the 5th gen Su-57 doesn't exist. The prototypes flown are with old engines. And in general - India, who really wanted to buy the 5th gen Su-57, basically having huge pile of cash ready on the table, has basically dropped out of it as declared capabilities of Su-57 just weren't there when it was tested (for example, beside the engine, while the radar is still great compare to previous generation, it is just half the declared range) and by the time it realistically may reach the true 5th gen capabilities India is already planning to be pretty close to having their own advanced development.
