Camp H. M. Smith, Hawaii, serves as headquarters of the United States Pacific Command. This unified command controls American military forces from the Arctic Ocean to the South Pole, and from the west coast of the United States to the Indian Ocean. The camp covers about 500 acres (200 hectares), and lies on Aiea Heights, 12 miles (19 kilometers) northwest of Honolulu's chief urban area. The camp was established in 1942 as a naval hospital and depot. In 1955, it was named for General Holland M. Smith.
