An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increases the time of availability on the combat zone.
The Battle of Midway was a major naval battle in the Pacific Theater of World War II that took place 4–7 June 1942, six months after the Empire of Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The U.S. Navy under Admirals Chester W. Nimitz, Frank J. Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chūichi Nagumo, and Nobutake Kondō north of Midway Atoll, inflicting devastating damage on the Japanese fleet. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare", while naval historian Craig Symonds called it "one of the most consequential naval engagements in world history, ranking alongside Salamis, Trafalgar, and Tsushima Strait, as both tactically decisive and strategically influential".
Hiryū was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the 1930s. Generally regarded as the only ship of her class, she was built to a modified Sōryū design. Her aircraft supported the Japanese invasion of French Indochina in mid-1940. She took part in the attack on Pearl Harbor and the Battle of Wake Island. During the first few months of the Pacific War, the ship supported the conquest of the Dutch East Indies in January 1942. The following month, her aircraft bombed Darwin, Australia, and continued to assist in the Dutch East Indies campaign. In April, Hiryū's aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean Raid.
Kaga (加賀) was an aircraft carrier built for the Imperial Japanese Navy (IJN) and was named after the former Kaga Province in present-day Ishikawa Prefecture. Originally intended to be one of two Tosa-class battleships, Kaga was converted under the terms of the Washington Naval Treaty to an aircraft carrier as the replacement for the battlecruiser Amagi, which had been irreparably damaged during the 1923 Great Kantō earthquake. Kaga was rebuilt in 1933–1935, increasing her top speed, improving her exhaust systems, and adapting her flight decks to accommodate more modern, heavier aircraft.
Akagi was an aircraft carrier built for the Imperial Japanese Navy (IJN), named after Mount Akagi in present-day Gunma Prefecture. Though she was laid down as an Amagi-class battlecruiser, Akagi was converted to an aircraft carrier while still under construction to comply with the terms of the Washington Naval Treaty. The ship was rebuilt from 1935 to 1938 with her original three flight decks consolidated into a single enlarged flight deck and an island superstructure. The second Japanese aircraft carrier to enter service, and the first large or "fleet" carrier, Akagi and the related Kaga figured prominently in the development of the IJN's new carrier striking force doctrine that grouped carriers together, concentrating their air power. This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942.
USS Yorktown (CV-5) was an aircraft carrier that served in the United States Navy during World War II. Named after the Battle of Yorktown in 1781, she was commissioned in 1937. Yorktown was the lead ship of the Yorktown class, which was designed on the basis of lessons learned from operations with the converted battlecruisers of the Lexington class and the smaller purpose-built USS Ranger.
USS Enterprise (CV-6) was a Yorktown-class carrier built for the United States Navy during the 1930s. She was the seventh U.S. Navy vessel of that name. Colloquially called "The Big E", she was the sixth aircraft carrier of the United States Navy. Launched in 1936, she was one of only three American carriers commissioned before World War II to survive the war. She participated in more major actions of the war against Japan than any other United States ship. These actions included the attack on Pearl Harbor — 18 Douglas SBD Dauntless dive bombers of her air group arrived over the harbor during the attack; seven were shot down with eight airmen killed and two wounded, making her the only American aircraft carrier with men at Pearl Harbor during the attack and the first to sustain casualties during the Pacific War — the Battle of Midway, the Battle of the Eastern Solomons, the Battle of the Santa Cruz Islands, various other air-sea engagements during the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf. Enterprise earned 20 battle stars, the most for any U.S. warship in World War II, and was the most decorated U.S. ship of World War II. She was also the first American ship to sink a full-sized enemy warship after the Pacific War had been declared when her aircraft sank the Japanese submarine I-70 on 10 December 1941. On three occasions during the war, the Japanese announced that she had been sunk in battle, inspiring her nickname "The Grey Ghost". By the end of the war, her planes and guns had downed 911 enemy planes, sunk 71 ships, and damaged or destroyed 192 more.
USS Lexington (CV-2), nicknamed "Lady Lex", was the name ship of her class of two aircraft carriers 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 terms of the Washington Naval Treaty of 1922, which essentially terminated all new battleship and battlecruiser construction. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Lexington and her sister ship, Saratoga, were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these included successfully staged surprise attacks on Pearl Harbor, Hawaii. The ship's turbo-electric propulsion system allowed her to supplement the electrical supply of Tacoma, Washington, during a drought in late 1929 to early 1930. She also delivered medical personnel and relief supplies to Managua, Nicaragua, after an earthquake in 1931.
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 Hornet (CV-8), the seventh U.S. Navy vessel of that name, was a Yorktown-class aircraft carrier of the United States Navy.
USS Midway (CVB/CVA/CV-41) is an aircraft carrier, formerly of the United States Navy, the lead ship of her class. Commissioned 8 days after the end of World War II, Midway was the largest ship in the world until 1955, as well as the first U.S. aircraft carrier too big to transit the Panama Canal. She operated for 47 years, during which time she saw action in the Vietnam War and served as the Persian Gulf flagship in 1991's Operation Desert Storm. Decommissioned in 1992, she is now a museum ship at the USS Midway Museum, in San Diego, California, and is the only remaining inactive U.S. aircraft carrier that is not an Essex-class aircraft carrier.
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 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 Battle of the Santa Cruz Islands, fought during 25–27 October 1942, sometimes referred to as the Battle of Santa Cruz or Third Battle of Solomon Sea, in Japan as the Battle of the South Pacific, was the fourth aircraft carrier battle of the Pacific campaign of World War II. It was also the fourth major naval engagement fought between the United States Navy and the Imperial Japanese Navy during the lengthy and strategically important Guadalcanal campaign. As in the battles of the Coral Sea, Midway, and the Eastern Solomons, the ships of the two adversaries were rarely in sight or gun range of each other. Instead, almost all attacks by both sides were mounted by carrier- or land-based aircraft.
USS St. Lo (AVG/ACV/CVE–63) was a Casablanca-class escort carrier of the United States Navy during World War II. On 25 October 1944, St. Lo became the first major warship to sink as the result of a kamikaze attack. The attack occurred during the Battle off Samar, part of the larger Battle of Leyte Gulf.
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases.
Jun'yō was a Hiyō-class aircraft carrier of the Imperial Japanese Navy (IJN). She was laid down as the passenger liner Kashiwara Maru (橿原丸), but was purchased by the IJN in 1941 while still under construction and converted into an aircraft carrier. Completed in May 1942, the ship participated in the Aleutian Islands Campaign the following month and in several battles during the Guadalcanal Campaign later in the year. Her aircraft were used from land bases during several battles in the New Guinea and Solomon Islands Campaigns.
An armoured flight deck is an aircraft carrier flight deck that incorporates substantial armour in its design.
The Zuihō class (瑞鳳型), also known as the Shōhō class (祥鳳型), consisted of two aircraft carriers built for the Imperial Japanese Navy (IJN) before World War II, the Zuihō and Shōhō. Both ships were originally built as submarine tenders, but were subsequently converted into carriers. Completed in early 1942, Shōhō supported the invasion forces in Operation MO, the invasion of Port Moresby, New Guinea, and was sunk by American carrier aircraft on her first combat operation during the Battle of the Coral Sea on 7 May. Shōhō was the first Japanese aircraft carrier to be sunk during World War II. Zuihō played a secondary role in the Battle of Midway in mid-1942 and did not engage any American aircraft or ships during the battle. The ship participated in the Guadalcanal campaign during the rest of 1942. She was lightly damaged during the Battle of the Santa Cruz Islands during this campaign and covered the evacuation of Japanese forces from the island in early 1943 after repairs.
George Chamberlain Duncan was a highly decorated United States Navy officer, World War Two veteran and flying ace. Born in Tacoma, Washington he was credited with destroying 13½ enemy aircraft and was awarded the Navy Cross during World War II.
