Concept
Fleet carrier
Résumé
A fleet carrier is an aircraft carrier designed to operate with the main fleet of a nation's navy. The term was developed during World War II, to distinguish it from the escort carrier and other less capable types. In addition to many medium-sized carriers, supercarriers, as well as some light carriers, are also classed as fleet carriers.
Aircraft carriers were designed in the years between World War I and World War II. Flight decks were installed on several different types of ships to explore the possibilities of operating naval aircraft without the performance limitations of flotation devices required for seaplanes and flying boats. The most successful of these early aircraft carriers were built from battlecruisers. Battlecruisers typically had a speed of about , which was several knots faster than the speed of contemporary battleships. Additional speed was not necessary for maintaining station with the battle fleet, but enabled the carrier to catch up with the battle fleet after temporarily leaving formation to turn into the wind for launch or recovery of aircraft. The speed of the carrier during launch effectively decreased the takeoff distance for embarked aircraft, so faster carriers could operate heavier aircraft with greater range and superior combat capability. As such naval aircraft became operational, no nation could risk fielding less capable aircraft; so the speed of later purpose-designed aircraft carriers was set by the speed of the converted battle cruisers. The Washington Naval Treaty of 1922 limited the displacement of purpose-designed aircraft carriers to 23,000 tons.
The idea of a modern fleet carrier was developed in 1931 by Admirals J.J. Clark and Harry E. Yarnell of the United States Navy. Fleet carriers, instead of operating as scouts for the fleet, would operate in unison with the fleet, to ward off air attacks and to strike opposing forces from the air. Cruisers and destroyers would protect fleet carriers. The fleet carriers would then displace battleships as the preeminent assets of the surface fleet.
