The Asiatic-Pacific Theater, was the area of operations of U.S. forces during World War II in the Pacific War during 1941-45. From mid-1942 until the end of the war in 1945, there were two U.S. operational commands in the Pacific. The Pacific Ocean Areas, divided into Central Pacific Area, North Pacific Area and South Pacific Area,[1]:652–653 were commanded by Admiral Chester Nimitz, Commander-in-Chief Pacific Ocean Areas. The South West Pacific Area, including the New Guinea, Philippines, Borneo, and the Dutch East Indies, was commanded by General Douglas MacArthur, Supreme Allied Commander South West Pacific Area.[2] During 1945, the United States added the U.S. Strategic Air Forces in the Pacific commanded by General Carl Spaatz.

Because of the complementary roles of the United States Army and the United States Navy in conducting war in the Pacific theater, there was no single Allied or U.S. commander (comparable to Eisenhower in the European Theater of Operations). There was no actual command; rather, SWPA, POA, and other forces and theatres such as the China-Burma-India Theater.

1944 Strategy Conference in Honolulu. Left to right: MacArthur, Roosevelt, Leahy, Nimitz. The discussion weighs the options of Formosa or the Philippine Islands as the next operational target in the Pacific theater.

  1. Note that the Battle of Leyte Gulf is listed in both the Central Pacific Area (under Nimitz) and in the South West Pacific Area (under MacArthur). Leyte Gulf is where Nimitz's western thrust across the central Pacific Ocean intersected MacArthur's northern thrust across the western Pacific Ocean. While the Pacific Ocean command structure was convoluted, operations were "designed to sequence the SWPA's operations with POA's forces across the central Pacific.[6]:IX-136The main purpose of sequencing is to arrange objectives/tasks in such a progression that collectively they lead to the accomplishment of the assigned ultimate objective in the shortest time possible and with the least loss of personnel and materiel."[6]:IX-135 Nimitz provided, but maintained control over, Admiral Halsey's Third Fleet to cover and support Admiral Kinkaid's Seventh Fleet operating under General MacArthur. The result of this imprecise arrangement was the crisis precipitating the Battle off Samar. Halsey was operating under Commander in Chief, Pacific Operating Area's (Nimitz') Operations Plan 8-44.[7]
