Since the second world war, the aircraft carrier has been a dominant symbol of naval might. Now however, the Aircraft carrier is facing a growing family of new and evolving threats, ranging from anti ship ballistic missiles and hypersonics, to more capable submarines and unmanned systems. Some argue that these threats mean the Carrier may be ready to go the way of the battleship, becoming obsolete. On the other hand, those same nations perfecting anti-carrier weapons are also investing extensively in new carriers of their own, suggesting they retain value. In this video I look at carrier evolution, fleets, roles, threats - and the potential future of these extremely expensive platforms.
