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:^[1]

"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:

• 1. All base and local defense forces (ground, naval and air) now assigned or to be assigned to forces in the South Pacific Area. The New Zealand Chiefs of Staff are responsible for the land defense of New Zealand, subject to such strategic decisions affecting this responsibility as may be made by the Commander-in-Chief, Pacific Fleet, for the conduct of naval operations in the Pacific Ocean Areas.
• 2. Assigned New Zealand, Free French, Dutch and other United Nations Naval forces.
• 3. Such fleet types and aircraft as may be assigned by the Commander-in-Chief, U.S. Pacific Fleet."

In July 1942 the South Pacific Area, under Admiral Ghormley, superseded by Admiral William Halsey Jr.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..^[2] 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 the operation out.
