I remember reading that the Soviets typically designed their aircraft for specific missions, for example the Mig-25 for very fast and could intercept supersonic bombers at high altitude. Of course, they were awful at dogfighting, except for running away.

The Soviets did & the results were there to be seen.The Russians churned out the SU-30 to be in the same class as the F-15E.Long range,heavy payload & multi-role.
