What defines an Aircraft Carrier Type of ship?

An aircraft carrier is defined primarily by its design and functionality that centers around enabling and supporting combat operations by aircraft. These ships serve as floating airbases, allowing for the deployment, recovery, and maintenance of aircraft, which are crucial for conducting air operations in various military scenarios. Their primary role includes launching and recovering fixed-wing aircraft and helicopters, making them pivotal in power projection, maritime strategy, and providing air support in naval operations.

While other types of vessels have specific roles, such as troop transport or supporting submarines, they do not possess the capabilities required to facilitate air operations. The design and function of an aircraft carrier distinctly highlight its purpose, which is to serve as a mobile platform for air dominance and aerial combat, reinforcing the fact that its primary focus is on supporting aircraft operations rather than ground attacks or troop transport.
