U. S. Navy
Seventh Fleet, under Vice-Admiral Thomas Kincaid:
This slow but powerful force included six over-age battleships, 18 small, slow escort carriers, five heavy cruisers, six light cruisers, 86 destroyers, 25 destroyer escorts, 11 frigates, and the usual gunboats, supply train and landing craft for an amphibious operation—plus all the PTs on the scene, the 45 veterans of the New Guinea blockade. Mission of the Seventh Fleet was close support of the Sixth Army landing force.
Third Fleet, under Admiral William Halsey:
This fast and mighty force had six new fast battleships, 16 fast carriers, six heavy cruisers, nine light cruisers and 58 destroyers. Mission of the Third Fleet was to prowl the waters north of the landings on the lookout for a chance to destroy once and for all the main Japanese battle fleet, especially its remaining carriers.
