Why aircraft carriers became capital ships

A capital ship is defined here by strategic weight, command value, and political visibility rather than by gun size or hull dimensions alone. Battleships, battlecruisers, and carriers can therefore differ radically in design while occupying the same strategic category. Their movements receive attention at the political as well as the operational level because a deployment signals national intent. Force Z illustrates the historical danger of this logic: politicians demanded a capital-ship presence even though admirals had reservations. In the lecture's January 2021 example, USS Nimitz remained in the Gulf amid Iranian threats against the American leadership and uranium enrichment. The case connects interwar carrier development with the modern crisis question of where the nearest carrier is.
