Aircraft Carrier

An aircraft carrier is a large warship designed to operate military aircraft at sea. Its most recognizable feature is the broad flight deck, where aircraft can take off and land. Modern carriers usually have a large hangar below the deck for storing and maintaining aircraft, as well as workshops, fuel systems, ammunition spaces and living areas for the crew. Aircraft carriers vary considerably in size and design.

Some use conventional propulsion, while a smaller number of large carriers use nuclear reactors to generate power and propulsion. Depending on the type of aircraft and carrier, takeoffs may be assisted by a catapult, while landing aircraft can be slowed by arresting wires stretched across the deck. A raised structure called the island normally stands on one side of the flight deck and contains the bridge, navigation equipment and other systems used to control flight operations.

A carrier does not normally operate alone. It usually forms part of a larger naval group that includes escort ships and, in many cases, submarines and supply vessels. These ships help protect the carrier and support its operations over long periods. The aircraft carried aboard may perform different missions, including air defense, surveillance, reconnaissance and strikes against surface or land targets, depending on the carrier and the forces using it.

Life on board is highly organized because hundreds or thousands of people may live and work in a confined environment while aircraft are operating nearby. The flight deck is divided into designated areas and strict procedures are used to reduce the risk of accidents. Because a carrier combines an airfield, a ship and a large support system, it is one of the most complex types of military vessel ever built.
