Shōkaku was the lead ship of her class of two aircraft carriers built for the Imperial Japanese Navy (IJN) shortly before the Pacific War. Along with her sister ship Zuikaku, she took part in several key naval battles during the war, including the attack on Pearl Harbor, the Battle of the Coral Sea, and the Battle of the Santa Cruz Islands, before being torpedoed and sunk by the U.S. submarine USS Cavalla at the Battle of the Philippine Sea.
USS United States (CVA-58) was to be the lead ship of a new design of aircraft carrier. On 29 July 1948, President Harry Truman approved construction of five "supercarriers", for which funds had been provided in the Naval Appropriations Act of 1949. The keel of the first of the five planned postwar carriers was laid down on 18 April 1949 at Newport News Drydock and Shipbuilding. The program was canceled in 1949, United States was not completed, and the other four planned carriers were never built.
USS Saratoga (CV-3) was a Lexington-class aircraft carrier built for the United States Navy during the 1920s. Originally designed as a battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the Washington Naval Treaty of 1922. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Saratoga and her sister ship, Lexington, were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these exercises included successful surprise attacks on Pearl Harbor, Hawaii. She was one of three prewar US fleet aircraft carriers, along with Enterprise and Ranger, to serve throughout World War II.
USS Forrestal (CVA-59), was a supercarrier named after the first United States Secretary of Defense James Forrestal. Commissioned in 1955, she was the United States' first completed supercarrier, and was the lead ship of her class. The other carriers of her class were USS Saratoga, USS Ranger and USS Independence. She surpassed the World War II Japanese carrier Shinano as the largest carrier yet built, and was the first designed to support jet aircraft.
The fifth USS Independence (CV/CVA-62) was an aircraft carrier of the United States Navy. She was the fourth and final member of the Forrestal class of conventionally powered supercarriers. She entered service in 1959, with much of her early years spent in the Mediterranean Fleet.
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships".
The Lexington-class aircraft carriers were a pair of aircraft carriers built for the United States Navy (USN) during the 1920s, the USS Lexington (CV-2) and USS Saratoga (CV-3). The ships were built on hulls originally laid down as battlecruisers after World War I, but under the Washington Naval Treaty of 1922, all U.S. battleship and battlecruiser construction was cancelled. The Treaty, however, allowed two of the unfinished ships to be converted to carriers. They were the first operational aircraft carriers in the USN and were used to develop carrier aviation tactics and procedures before World War II in a series of annual exercises.
The Yorktown class was a class of three aircraft carriers built for the United States Navy and completed shortly before World War II, the Yorktown (CV-5), Enterprise (CV-6), and Hornet (CV-8). They immediately followed Ranger, the first U.S. aircraft carrier built as such, and benefited in design from experience with Ranger and the earlier Lexington class, which were conversions into carriers of two battlecruisers that were to be scrapped to comply with the Washington Naval Treaty, an arms limitation accord.
The Midway-class was a class of three United States Navy aircraft carriers. The lead ship, USS Midway, was commissioned in September 1945 and decommissioned in 1992. USS Franklin D. Roosevelt was commissioned in October 1945, and taken out of service in 1977. USS Coral Sea was commissioned in April 1947, and decommissioned in 1990.
The Kitty Hawk-class supercarriers of the United States Navy were an incremental improvement on the Forrestal-class vessels. Three were built, all in the 1960s, Kitty Hawk (CV-63) (1961–2009), Constellation (CV-64) (1961–2003), and America (CV-66) (1965–1996), as well as the variant John F. Kennedy (CV-67) (1967–2007). All are now decommissioned.
The Illustrious class was a class of aircraft carrier of the Royal Navy that included some of the most important British warships in the Second World War. They were laid down in the late 1930s as part of the rearmament of British forces in response to the emerging threats of Nazi Germany, Fascist Italy and Imperial Japan.
Shinano (信濃) was an aircraft carrier built by the Imperial Japanese Navy (IJN) during World War II, the largest such built up to that time. Laid down in May 1940 as the third of the Yamato-class battleships, Shinano's partially complete hull was ordered to be converted to an aircraft carrier following Japan's disastrous loss of four of its original six fleet carriers at the Battle of Midway in mid-1942. The advanced state of her construction prevented her conversion into a fleet carrier, so the IJN decided to convert her into a carrier that supported other carriers.
Taihō was an aircraft carrier of the Imperial Japanese Navy during World War II. Possessing heavy belt armor and featuring an armored flight deck, she represented a major departure from prior Japanese aircraft carrier design and was expected to not only survive multiple bomb, torpedo, or shell hits, but also continue fighting effectively afterwards.
Amagi (天城) was an Unryū-class aircraft carrier built for the Imperial Japanese Navy during World War II. Named after Mount Amagi, and completed late in the war, she never embarked her complement of aircraft and spent the war in Japanese waters. The ship capsized in July 1945 after being hit multiple times during airstrikes by American carrier aircraft while moored at Kure Naval Base. Amagi was refloated in 1946 and scrapped later that year.
SCB-27 was the United States Navy designation for a series of upgrades to the Essex-class aircraft carriers, conducted between 1947 and 1955. These upgrades were intended to allow the World War II-era carriers to operate jet aircraft.
An armoured flight deck is an aircraft carrier flight deck that incorporates substantial armour in its design.
Aircraft carriers are warships that evolved from balloon-carrying wooden vessels into nuclear-powered vessels carrying many dozens of fixed- and rotary-wing aircraft. Since their introduction they have allowed naval forces to project air power great distances without having to depend on local bases for staging aircraft operations.
The Essex class is a retired class of aircraft carriers of the United States Navy. The 20th century's most numerous class of capital ship, the class consisted of 24 vessels, which came in "short-hull" and "long-hull" versions. Thirty-two ships were ordered, but as World War II wound down, six were canceled before construction, and two were canceled after construction had begun. Fourteen saw combat during World War II. None were lost to enemy action, though several sustained crippling damage. Essex-class carriers were the backbone of the U.S. Navy from mid-1943 and, with the three Midway-class carriers added just after the war, continued to be the heart of U.S. naval strength until supercarriers joined the fleet in the 1950s, 1960s and 1970s. Several of the carriers were rebuilt to handle heavier and faster aircraft of the early jet age, and some served until well after the Vietnam War. Of the 24 ships in the class, four have been preserved as museum ships.
