World War II: Off the coast of Okinawa, the aircraft carrier USS Bunker Hill is hit by two kamikazes, killing 346 of its crew. Although badly damaged, the ship is able to return to the U.S. under its own power.

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 was named for the Battle of Bunker Hill in the American Revolutionary War. Commissioned in May 1943 and sent to the Pacific Theater of Operations, the ship participated in battles in the Southwest Pacific, Central Pacific and the drive toward Japan through Iwo Jima, Okinawa, and air raids on the Japanese homeland.

While covering the invasion of Okinawa, Bunker Hill was struck by two kamikazes in quick succession, setting the vessel on fire. Casualties exceeded 600, including 352 confirmed dead and an additional 41 missing, with 264 wounded. These were the second heaviest personnel losses suffered by any carrier to survive the war after Franklin. After the attack, Bunker Hill returned to the U.S. mainland and was still under repair when hostilities ended.

After the war, Bunker Hill was employed as a troop transport bringing American service members back from the Pacific, and was decommissioned in 1947. While in reserve the vessel was reclassified as an attack carrier (CVA), then an antisubmarine carrier (CVS) and finally an Auxiliary Aircraft Landing Training Ship (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, Bunker Hill 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.

Okinawa Prefecture (沖縄県, Japanese: Okinawa-ken, Okinawan: ʔUchinā-chin) is a prefecture of Japan located on the Ryukyu Islands. Okinawa Prefecture is the southernmost and westernmost prefecture of Japan, has a population of 1,457,162 (2 February 2020) and has a geographic area of 2,281 km2 (880 sq mi).

Naha is the capital and largest city of Okinawa Prefecture, with other major cities including Okinawa, Uruma, and Urasoe. Okinawa Prefecture encompasses two thirds of the Ryukyu Islands, including the Okinawa, Daitō and Sakishima groups, extending 1,000 kilometres (620 mi) southwest from the Satsunan Islands of Kagoshima Prefecture to Taiwan (Hualien and Yilan Counties). Okinawa Prefecture's largest island, Okinawa Island, is the home to a majority of Okinawa's population. Okinawa Prefecture's indigenous ethnic group are the Ryukyuan people, who also live in the Amami Islands of Kagoshima Prefecture.

Okinawa Prefecture was ruled by the Ryukyu Kingdom from 1429 and unofficially annexed by Japan after the Invasion of Ryukyu in 1609. Okinawa Prefecture was officially founded in 1879 by the Empire of Japan after seven years as the Ryukyu Domain, the last domain of the Han system. Okinawa Prefecture was occupied by the United States of America during the Allied occupation of Japan after World War II, and governed by the Military Government of the Ryukyu Islands from 1945 to 1950 and Civil Administration of the Ryukyu Islands from 1950 until the prefecture was returned to Japan in 1972. Okinawa Prefecture comprises just 0.6 percent of Japan's total land mass but about 26,000 (75%) of United States Forces Japan personnel are assigned to the prefecture; the continued U.S. military presence in Okinawa is controversial.
