Aircraft Carrier(Aircraft Carrier), referred to as "aircraft carrier" and "empty mother", is a large-scale surface ship that uses carrier-based aircraft as its main combat weapon. The hull usually has a huge deck and the island on the right. The aircraft carrier is generally the core ship of an aircraft carrier battle group. Other ships in the fleet provide its protection and supply, while the aircraft carrier provides air cover and long-range strike capabilities. Development so far, Aircraft carriers are already an indispensable weapon of the modern Navy and one of the most important ships in naval warfare. Relying on aircraft carriers, a country can exert military pressure and conduct operations far from its territory and not relying on local airport conditions. The aircraft carrier has become an indispensable weapon of the modern Navy and has become a symbol of a country's comprehensive national strength. Aircraft carriers are generally divided into two types according to the power method: 1. Conventional power, such as the United States Kitty Hawk; 2. Nuclear power, such as Enterprise and Nimitz. It can also be divided into light aircraft carriers(because the cost is cheaper than a Super aircraft carrier, also known as a "civilian aircraft carrier") with a displacement of less than 30,000 tons. Medium-sized aircraft carriers, such as the French Charles de Gaulle, have a full-load displacement of 39,680 tons. Heavy aircraft carriers, such as Nimitz, have a full-load displacement of 91,487 tons.
