South Pacific area

The South Pacific Area (SOPAC) was a multinational U.S.-led military command active during World War II. It was a part of the U.S. Pacific Ocean Areas under Admiral Chester Nimitz.

Instructions to the senior U.S. Army officer of the command, dated 7 July 1942, said:

"The establishment of the Pacific Ocean Area as an area of United States strategical responsibility under the command of the Commander-in-Chief, U.S. Pacific Fleet, became effective on May 8, 1942. The Commander-in-Chief, U.S. Pacific Fleet, has been designated the "Commander-in-Chief, Pacific Ocean Area". Under the Commander-in-Chief, Pacific Ocean Area, a U.S. Naval officer has been designated as "Commander, South Pacific Area". The South Pacific Force under COMSOPAC include the following:

In July 1942 the South Pacific Area, under Admiral Ghormley, superseded by Admiral William Halsey Jr. from 16 October, comprised four commands: Amphibious Forces, South Pacific (AmphibForSoPac), under Admiral Richmond K. Turner, South Pacific Naval Forces under Admiral Ghormley, U.S. Army Forces South Pacific under Major General Millard Harmon, and South Pacific Air Forces under Admiral John S. McCain, Sr.. At a later stage Transport Group, South Pacific (TransGrpSoPac) was added to the organisation.

The organisation's first major battle was the Battle of Guadalcanal. Admiral Ghormley's Operations Order 1-42 established two task forces, Task Force 61 and Task Force 63, to carry out the operation.

On September 20, 1942, six weeks after the first American amphibious operation of the war got underway at Guadalcanal, Vice Admiral Aubrey Fitch assumed command of Aircraft, South Pacific Force (AirSoPac). Not a desk-bound admiral, he carried out numerous, hazardous flights into the combat zones, inspecting air activities and bases for projected operations. For these, he received a Distinguished Flying Cross. Under Fitch's command, AirSoPac—ultimately encompassing not only Navy but Army, Marine Corps, and Royal New Zealand Air Force air units—achieved great success in aiding the Allied campaign in the South Pacific Area.
