USS Yorktown (CV/CVA/CVS-10) is one of 24 Essex-class aircraft carriers built during World War II for the United States Navy. She is named after the Battle of Yorktown of the American Revolutionary War, and is the fourth U.S. Navy ship to bear the name. Initially to have been named Bonhomme Richard, she was renamed Yorktown while under construction to commemorate USS Yorktown (CV-5), lost at the Battle of Midway in June 1942. 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 the early 1950s as an attack carrier (CVA), and then eventually became an antisubmarine carrier (CVS). She was recommissioned too late to participate in the Korean War but served for many years in the Pacific, including duty in the Vietnam War, in which she earned five battle stars. Late in her career, she served as a recovery ship for the Apollo 8 space mission, and was used in the movie Tora! Tora! Tora! which recreated the Japanese attack on Pearl Harbor; and in the science fiction film The Philadelphia Experiment.
