An aircraft carrier is a large naval ship designed to serve as a floating airbase. It can carry and launch various types of military aircraft, such as fighter jets and helicopters, allowing them to operate far from land. This capability makes aircraft carriers essential for naval power, enabling countries to project their military strength across oceans. These ships are equipped with advanced technology, including radar systems and catapults, to help aircraft take off and land safely. Notable examples of aircraft carriers include the USS Nimitz and the HMS Queen Elizabeth, which play crucial roles in modern naval operations and international security.
