The number of planes that a navy ship can carry depends on the type of ship. Aircraft carriers are specifically designed to carry and operate aircraft, and can carry hundreds of planes. Other types of ships, such as cruisers, destroyers, and frigates, may carry a small number of aircraft, typically helicopters, for reconnaissance, anti-submarine warfare, or search and rescue missions. The exact number of planes that a particular ship can carry varies depending on the ship's size, design, and mission.
