The total air force demand for fifth-generation fighter jets is estimated at 200–250 aircraft, and it is now assumed that large-scale deliveries of the Su-57 will begin after 2025, at the end of the tests and launch into the engine of the "second stage". This approach is fraught with the fact that the first squadrons on the new aircraft did not reach combat readiness before 2027-2028, whereas by that time NATO countries in Europe, Japan and stationed in Europe and the Far East will have combat units on fifth generation fighters. East contingents of the USAF. Suffice it to say that the F-35 has already produced about 400 units as of “now”, and in the next decade they will be received, among other Air Forces not only in Poland, but already in Finland and Romania, which are lagging behind in the number of modern aircraft in Russia it would be completely indecent.
You can console yourself for a long time with the fact that the war with NATO (or their allies) “in case of anything” will be nuclear, and under these conditions it does not matter what kind of aircraft Russian pilots will have to engage in air combat. However, it is worth noting that the presence of well-equipped and numerous general-purpose forces, including the Air Force, makes it possible, firstly, to maximize the threshold for the use of nuclear weapons, and secondly, to exclude situations in which the nuclear response is still unacceptable, and "Conventional" forces are not enough.
