Looking back on my knowledge of the Cold War, there seem to be continual well-contested arms races in several areas of major military technology, such as strategic bombers, nuclear weapons, ICBMs, submarines, etc. But I don't know of any serious attempts by the Soviet navy to field a fleet of supercarriers akin to the USN Nimitz class and its predecessor and successor designs.

Fast forward to today, and the US still maintains a peculiar advantage in this one area of military power, even though other major powers have striven to develop equivalent capabilities in so many other areas of defense technology.

So my question is, did the USSR try and fail to field supercarriers in large numbers? Or did it just not see them as a priority in their military strategy?
