USS Bunker Hill (CV/CVA/CVS-17, AVT-9) was one of 24 Essex-class aircraft carriers built during World War II for the United States Navy. The ship, the second US Navy ship to bear the name, was named for the Battle of Bunker Hill. Bunker Hill was commissioned in May 1943, and served in several campaigns in the Pacific Theater of Operations, earning eleven battle stars and a Presidential Unit Citation. Bunker Hill was sometimes known as the "Holiday Express" for her many attacks launched around the end of the year[citation needed. She was badly damaged in May 1945 by Japanese kamikaze attacks, with the loss of hundreds of her crew, becoming one of the most heavily damaged carriers to survive the war.
After the attack she returned to the U.S. mainland for repairs and was decommissioned in 1947. While in reserve she was reclassified as an attack carrier (CVA), then an antisubmarine carrier (CVS), and finally an aircraft transport (AVT), but was never modernized and never saw active service again. Bunker Hill and Franklin were the only Essex-class ships never recommissioned after World War II.
Stricken from the Naval Vessel Register in 1966, she served as an electronics test platform for many years in San Diego bay, and was sold for scrap in 1973. An effort to save her as a museum ship in 1972 was unsuccessful.
