USS Yorktown (CV/CVA/CVS-10) is one of 24 s built during World War II for the United States Navy. Initially to have been named Bonhomme Richard, she was renamed Yorktown while still under construction, after the , which was sunk at the Battle of Midway. She is the fourth U.S. Navy ship to bear the name, though the previous ships were named for the 1781 Battle of Yorktown. Yorktown was commissioned in April 1943, and participated in several campaigns in the Pacific Theater of Operations, earning 11 battle stars and the Presidential Unit Citation.

Decommissioned shortly after the end of the war, she was modernized and recommissioned in February 1953 as an attack carrier (CVA), and served with distinction during the Korean War. The ship was later modernized again with a canted deck, eventually becoming an anti-submarine carrier (CVS) and served for many years in the Pacific, including duty in the Vietnam War, during which she earned five battle stars. The carrier served as a recovery ship for the December, 1968, Apollo 8 space mission, the first crewed ship to reach and orbit the Moon, and was used in the 1970 film Tora! Tora! Tora!, which recreated the Japanese attack on Pearl Harbor, and in the 1984 science fiction film The Philadelphia Experiment.

Yorktown was decommissioned in 1970 and in 1975 became a museum ship at Patriots Point, Mount Pleasant, South Carolina, where she was designated a National Historic Landmark.

Construction and commissioning Work was begun on Bonhomme Richard when her keel was laid down on 1 December 1941 at Newport News, Virginia, by the Newport News Shipbuilding & Drydock Company, six days before the Attack on Pearl Harbor. She was renamed on 26 September 1942 as USS Yorktown to commemorate the loss of during the Battle of Midway in June 1942, and launched on 21 January 1943, sponsored by Eleanor Roosevelt. Yorktown was commissioned on 15 April 1943, with Captain Joseph J. Clark in command.

Service history World War II

Yorktown remained in the Naval Station Norfolk area until 21 May 1943, when she got underway for shakedown training in the vicinity of Trinidad. She returned to Norfolk on 17 June and began post-shakedown availability. The aircraft carrier completed repairs on 1 July and began air operations out of Norfolk until 6 July, when she exited Chesapeake Bay on her way to the Pacific Ocean. She transited the Panama Canal on 11 July and departed Balboa, Panama, on 12 July. The warship arrived in Pearl Harbor on 24 July and began a month of exercises in the Hawaiian Islands. On 22 August, she stood out of Pearl Harbor, bound for her first combat of the war. Her task force, TF 15, arrived at the launching point about from Marcus Island early on the morning of 31 August. She spent most of that day launching fighter and bomber strikes on Marcus Island before beginning the retirement to Hawaii that evening. The aircraft carrier reentered Pearl Harbor on 7 September and remained there for two days.

On 9 September, she stood out to sea, bound for the West Coast of the United States. She arrived in San Francisco on 13 September, loaded aircraft and supplies, and returned to sea on 15 September. Four days later, the aircraft carrier reentered Pearl Harbor. Yorktown returned to sea to conduct combat operations on 29 September. Early on the morning of 5 October, she began two days of air strikes on Japanese installations on Wake Island. After retiring to the east for the night, she resumed those air raids early on the morning of 6 October and continued them through most of the day. That evening, the task group began its retirement to Hawaii. Yorktown arrived at Oahu on 11 October and, for the next month, conducted air training operations out of Pearl Harbor.

Marshall and Gilbert Islands

On 10 November, Yorktown departed Pearl Harbor in company with Task Force 38—the Fast Carrier Task Force, Pacific Fleet—to participate in her first major assault operation, the occupation of the Gilbert Islands. On 19 November, she arrived at the launch point near Jaluit and Mili Atoll and, early that morning, launched the first of a series of raids to suppress enemy airpower during the amphibious assaults on Tarawa, Abemama, and Makin. The next day, she sent raids back to the airfield at Jaluit; some of her planes also supported the troops wresting Makin from the Japanese. On 22 November, her air group concentrated upon installations and planes at Mili once again. Before returning to Pearl Harbor, the aircraft carrier made passing raids on the installations at Wotje and Kwajalein Atolls on 4 December. The warship reentered Pearl Harbor on 9 December and began a month of air training operations in the Hawaiian Islands.

On 16 January 1944, the warship exited Pearl Harbor once again to support an amphibious assault – Operation Flintlock, the Marshall Islands invasion. The Fast Carrier Task Force was then attached to Fifth Fleet and re-designated TF 58, with the Yorktown task group re-designated as Task Group 58.1 (TG 58.1). When TG 58.1 arrived at its launching point early on the morning of 29 January, carriers Yorktown, , and began sending air strikes aloft at about 05:20 for attacks on Taroa airfield located on Maloelap Atoll. Throughout the day, her aircraft hit Maloelap in preparation for the assaults on Majuro and Kwajalein scheduled for 31 January. On 30 January, Yorktown and her sister carriers shifted targets to Kwajalein to begin softening up one of the targets. When the troops stormed ashore on 31 January, Yorktown aviators continued their strikes on Kwajalein in support of the troops attacking that atoll. The same employment occupied the Yorktown air group during the first three days in February. On 4 February, however, the task group retired to the fleet anchorage at recently secured Majuro Atoll.

Central Pacific raids Over the next four months, Yorktown participated in a series of raids in which she ranged from the Marianas in the north to New Guinea in the south. After eight days at Majuro, she sortied with her task group on 12 February to conduct air strikes on the main Japanese anchorage at Truk Atoll. Those highly successful raids occurred on 16–17 February. On 18 February, the carrier set a course for the Marianas, and on 22 February, conducted a single day of raids on enemy airfields and installations on Saipan. That same day, she cleared the area on her way back to Majuro. The warship arrived in Majuro lagoon on 26 February and remained there. On 8 March, the carrier stood out of Majuro, rendezvoused with the rest of TF 58, and shaped a course for Espiritu Santo in the New Hebrides. She reached her destination on 13 March and remained there for 10 days before getting underway for another series of raids on the Japanese middle defense line. On 30–31 March, she launched air strikes on Japanese installations located in the Palau Islands; and on 1 April, her aviators went after the island of Woleai. Five days later, she returned to her base at Majuro for a week of replenishment and recreation.

On 13 April, Yorktown returned to sea once more. On this occasion however, she laid in a course for the northern coast of New Guinea. On 21 April, she began launching raids in support of General Douglas MacArthur's assault on the Hollandia (currently known as Jayapura) area. That day, her aviators attacked installations in the Wakde-Sarmi area of northern New Guinea. On 22–23 April, they shifted to the landing areas at Hollandia themselves and began providing direct support for the assault troops. After those attacks, she retired from the New Guinea coast for another raid on Truk lagoon, which her aircraft carried out on 29 and 30 April. The aircraft carrier returned to Majuro on 4 May; however, two days later she got underway again, bound for Oahu. The warship entered Pearl Harbor on 11 May, and for the next 18 days, conducted training operations in the Hawaiian Islands. On 29 May, she headed back to the Central Pacific. Yorktown entered Majuro lagoon again on 3 June and began preparations for her next major amphibious support operation—the assault on the Marianas.

Marianas and Palau Islands

On 6 June, the aircraft carrier stood out of Majuro with TF 58 and set a course for the Mariana Islands. After five days steaming, she reached the launch point and began sending planes aloft for the preliminary softening up of targets in preparation for the invasion of Saipan. Yorktown aircrews concentrated primarily upon airfields located on Guam. Those raids continued until 13 June, when Yorktown, with two of the task groups of TF 58, steamed north to hit targets in the Bonin Islands. That movement resulted in a one-day raid on 16 June before the two task groups headed back to the Marianas to join in the Battle of the Philippine Sea. TF 58 reunited on 18 June and began a short wait for the approaching Japanese Fleet and its aircraft.

On the morning of 19 June, Yorktown aircraft began strikes on Japanese air bases on Guam in order to deny them to their approaching carrier-based air and to keep the land-based planes out of the fray. Duels with Guam-based aircraft continued until mid-morning. At about 10:17, however, she got her first indication of the carrier plane attacks when a large bogey appeared on her radar screen. At that point she divided her attention, sending part of her air group back to Guam and another portion of it out to meet the raid closing from the west. Throughout the battle, Yorktowns planes continued to strike the Guam airfields and intercept the carrier raids. During the first day of the Battle of the Philippine Sea, Yorktown aircraft claimed 37 enemy planes destroyed and dropped 21 tons of bombs on the Guam air bases.

On the morning of 20 June, Yorktown steamed generally west with TF 58 while search planes groped for the fleeing enemy task force. Contact was made with the enemy at about 15:40 when a pilot from spotted the retiring Combined Fleet units. Yorktown launched a 40-plane strike between 16:23 and 16:43. Her planes found Admiral Jisaburō Ozawa's force at about 18:40 and began a 20-minute attack during which they went after on which they succeeded in scoring some hits. They, however, failed to sink that carrier. They also attacked several other ships in the Japanese force, though no records show a confirmed sinking to the credit of the Yorktown air group. On 21 June, the carrier joined in the futile stern chase on the enemy carried out by TF 58 but gave up that evening when air searches failed to contact the Japanese. Yorktown returned to the Marianas area and resumed air strikes on Pagan Island on 22–23 June. On 24 June, she launched a series of raids on Iwo Jima. On 25 June, she laid in a course for Eniwetok and arrived there two days later. On 30 June, the aircraft carrier headed back to the Marianas and the Bonins. She renewed combat operations on 3–4 July with a series of attacks on Iwo Jima and Chichi Jima. On 6 July, the warship resumed strikes in the Marianas and continued them for the next 17 days. On 23 July, she headed off to the west for a series of raids on Yap, Ulithi, and the Palaus. She carried out those attacks on 25 July and arrived back in the Marianas on 29 July.

On 31 July, she cleared the Mariana Islands and headed—via Eniwetok and Pearl Harbor—back to the United States. Yorktown arrived in the Puget Sound Navy Yard on 17 August and began a two-month overhaul. She completed repairs on 6 October and departed Puget Sound on 9 October. She stopped at the Alameda Naval Air Station from 11 to 13 October to load planes and supplies and then set a course back to the western Pacific. After a stop at Pearl Harbor from 18 to 24 October, Yorktown arrived back in Eniwetok on 31 October. She departed the lagoon on 1 November and arrived at Ulithi on 3 November. There, she reported for duty with TG 38.4. The task group left Ulithi on 6 November.
