Aircraft Carriers (1983: Doomsday)

Aircraft carriers are seagoing platforms to both launch and recover aircraft. They are used in surface warfare to both launch aircraft attacking enemy ships or submarines as well as use a fighter screen to intercept enemy combat aircraft, to support ground operations by launching ground attack missions, as well as for support during natural disasters or a time of crisis.

Oftentimes for nations, they are a sign of prestige and used to impress potential allies or deter enemies.
