United States Indo-Pacific Command (USINDOPACOM) is a unified combatant command of the United States Armed Forces responsible for the Indo-Pacific region. Formerly known as United States Pacific Command (USPACOM) since its inception in 1947, the command was renamed to U.S. Indo-Pacific Command in 2018, in recognition of the increasing connectivity between the Indian and Pacific oceans.It is the oldest and largest of the unified combatant commands. Its commander, the senior U.S. military officer in the Pacific, is responsible for military operations in an area that encompasses more than 100 million square miles (260,000,000 km2), or roughly 52 percent of the Earth's surface, stretching from the waters of the West Coast of the United States to the east coast maritime borderline waters of Pakistan at the meridian 66° longitude east of Greenwich and from the Arctic to the Antarctic. The commander reports to the President of the United States through the Secretary of Defense and is supported by service component and subordinate unified commands, including U.S. Army Pacific, Marine Forces Pacific, U.S. Pacific Fleet, Pacific Air Forces, U.S. Forces Japan, U.S. Forces Korea, Special Operations Command Korea, and Special Operations Command Pacific.
