Soviet and Russian responses to the F-22 generation

How did the Soviet Union react to the emerging F-22 programme?

It pursued counter-projects, but the Soviet collapse and later Russian funding and governance problems left those responses arriving far behind the American development cycle.

The answer begins before the Soviet Union's collapse, when awareness of the American advanced-fighter programme was already shaping counter-projects. It connects demonstrators such as the Su-47 and later Su-57 and MiG-41 ambitions to the effort to recover comparable capability. The long development timelines matter because requirements and technologies can become fixed while a programme waits through political and industrial disruption. By the time a delayed counter enters service, the rival may already be building the next generation. The speakers therefore frame aerospace competition as an institutional race in research continuity and production capacity, not only a contest between published aircraft specifications.
