Marc Mitscher
U.S. Third Fleet, commanded by Admiral William F. Halsey Jr., with Task Force 38 (TF 38, the Fast Carrier Task Force, commanded by Vice Admiral Marc Mitscher), as its main component, would provide more distant cover and support for the invasion. A fundamental defect in this plan was there would be no single American naval admiral in overall command. Kinkaid fell under MacArthur as Supreme Allied Commander Southwest Pacific, whereas Halsey's Third Fleet reported to Nimitz as C-in-C Pacific Ocean Areas. This lack of unity of command, along with failures in communication, was to produce a crisis and very nearly a strategic disaster for the American forces. By coincidence, the Japanese plan, using three separate fleets, also lacked an overall commander.
