Why medium powers retained carriers after the Cold War

Why did medium powers keep aircraft carriers after the Cold War?

Because globally exposed states still need flexible expeditionary airpower, and meaningful carrier contributions strengthen alliance support as well as national reach.

Carrier value depends on the kind of power projection a state needs rather than on superpower status alone. Britain remains deeply exposed to global trade, shipping insurance, financial services, and the movement of goods, so distant disruption can affect its economy directly. A carrier group provides a flexible way to contribute to coalition operations beyond home waters. That contribution also builds alliance reciprocity: a state able to share difficult deployments is more likely to receive assistance when its own interests are threatened.
