The aviation carrier, referred to as "carrier" and "craft carrier," was a large surface ship with carrier-based aircraft as its main combat weapon.
The hull usually had a huge flight deck on top and an island located either on the left or right side. The aircraft carrier was usually the core ship of a fleet. Other ships in the fleet provided protection and supply, while the aircraft carrier provided air cover and long-range strike capability.
In the present day, aircraft carriers were an indispensable weapon of the modern navy and one of the most important ships in naval warfare. By relying on aviation carriers, a country could exert military pressure and conduct operations without relying on local airports in places far from its homeland.
Therefore, aviation carriers were an indispensable weapon for the modern navy and also a symbol of a country's overall power.
