Like all conflicts, that in Korea had its strange and unpredictable characteristics. One of these was the fact that, so far as control of the seas was concerned, the war started with the exploitation phase. It was never necessary to fight the convoys through. But of this no one could at first be sure, and with men and supplies in very large quantity committed to the ocean highways, and with the extent of opposition doubtful, insurance was necessary. To maintain sea control, should new enemy forces choose to dispute it, further combatant strength was needed .
Yet almost all the fighting ships west of the continental United States had already been committed. Statistically speaking, the division of the Pacific Fleet in June between ships operating in home waters and those to the westward was roughly an even one. One hundred and twenty-five naval vessels of all types were based on the west coast while another 128 were scattered between Alaska, the Hawaiian Islands, the trust territories, and the Western Pacific. But the statistics are deceptive, including as they do auxiliaries, small craft, and local forces, and the distribution of major combatant types was very different. Of 86 active units, three-quarters were based on the west coast of the United States.
Of the three large aircraft carriers in the Pacific Fleet , one was with Task Force 77 and two were in the San Diego area, where the Fleet's two escort carriers also based. The Fleet contained no active battleship . Two cruisers were already at work in Far Eastern waters and the remaining four were on the west coast. Of a total of 57 destroyer types and 30 submarines, 12 and 6 respectively were operating outside of continental waters, 12 and 4 were operating under ComNavFE . Quite clearly any naval reinforcement had to come a long way.
