An aircraft carrier is a large naval ship designed to serve as a mobile airbase at sea. It can carry, launch, and recover various types of aircraft, including fighter jets and helicopters. These ships are equipped with a flight deck, hangars, and advanced technology to support military operations. Aircraft carriers play a crucial role in naval warfare and power projection, allowing a country to deploy air power without relying on local bases. They are often accompanied by a group of support ships, forming a carrier strike group that enhances their operational capabilities and security.
