Chapter 3: War Begins


Part 2: The Far East Command

          Despite optimistic statements issuing from the upper levels, the readiness of the United States for war in the summer of 1950 was very doubtful. For the war with which the country found itself confronted, this was the more the case. The Army had a total of ten combat divisions, all but one understrength. The Marines had two, both undermanned. The Navy was in the process of being cut down and even the Air Force, despite public and congressional favor, had been forced to narrow its focus and channel its capabilities.

          The interaction of budget ceiling and strategic plan had led to emphasis on long-range bombardment and the European theater, an emphasis reflected in the deployment of American strength. The ground forces were divided between the continent of Europe, the continental United States, and occupation duty in Japan. The Navy's larger half was in the Atlantic. The weight of the Strategic Air Command and of other Air Force units lay at home and in the forward European bases. On the assumption that the first and most important Communist objective was Western Europe, it may be said that this deployment proved itself. No war came there. But for the war that did come this posture was more than a little awkward.

Table 1.---THE FAR EAST COMMAND, JUNE-AUGUST 1950

Command Structure diagram for Far East Command, June-August 1950

          American forces in the Orient in 1950 were organized into the presumably unified command of General MacArthur, Commander in Chief Far East Command, who was also, as Supreme Commander for the Allied Powers, responsible for the occupation of Japan. Occupation responsibilities bulked large at Headquarters, but in addition to these duties General MacArthur was charged with the defense of Japan, Okinawa, the Marianas, and the Philippines. To enable him to carry out these missions, forces of all three services had been assigned CincFE.

          Notwithstanding the European orientation of strategy, the needs of the Japanese occupation had brought a large proportion of American ground strength to the Far East. On paper, Army Forces Far East was not unimpressive: its four divisions--the 7th, 24th, and 25th Infantry Divisions, and the dismounted 1st Cavalry Division--organized as the United States Eighth Army, were commanded by Lieutenant General Walton H. Walker, USA, who had been one of Patton's corps commanders in France. But all of Walker's divisions were understrength, with only two battalions to a regiment, and were undertrained and underequipped as well. No Army theater headquarters had been established, but the functions of such an organization were carried out by CincFE's staff.

          The Far East Air Forces, the air component of General MacArthur's command, were commanded by Lieutenant General George E. Stratemeyer, USAF. In June 1950 FEAF contained five fighter and two bomber wings, a transport wing, and miscellaneous support units making up a total of some 1,200 aircraft. The principal mission of the Far East Air Forces, the air defense of Japan, Okinawa, Guam, and the Philippines, was reflected in the order of battle: of the 553 aircraft in organized units, 365 were F-80C jet fighters [Lockheed F-80 Shooting Star]. These aircraft, which had recently replaced the piston-engined F-51 Mustang [North American], had, as befitted their intended purpose, comparatively high performance. But their combat radius without external fuel tanks was limited to100 miles; with external fuel no bombs could be carried, and their operation required sizable modern airstrips. The efficiency of General Stratemeyer's command suffered from certain deficiencies of material, its engineering support was inadequate, and training had been restricted by budget cuts.

          Joint training by the Army and Air Force in Japan had been minimal, in part owing to the defensive nature of their missions, in part to the emphasis in all American military planning on strategic rather than tactical air operations. The Air Force, it should be said, had indeed proposed some exercises at the division level which would involve a working out of the mechanics of air support, and had suggested the creation of a Joint Operations Center. But occupation duties and the lack of suitable maneuver areas had adversely affected ground force readiness, and the Army, not wishing to sacrifice its program of small-unit training, had declined the offer. The result was that such joint exercises as were held were small in scale, and formal and cut and dried in nature.

          Despite these limitations, the main strength of the Far East Command lay on the ground and in the air. Only a little over a third of the Navy's active strength was in the Pacific, only a fifth of that was in the Far East, and the naval component under Vice Admiral C. Turner Joy was very small. But although Naval Forces Far East was largely a housekeeping command, ComNavFE did control, in Task Force 96, a small amount of fighting strength, and in Task Force 90 the nucleus of an amphibious force.

           The combat units of Task Force 96, Naval Forces Japan, were fast and able ships, but none mounted anything larger than a 5-inch gun. Juneau, Captain Jesse C. Sowell, flagship of Rear Admiral John M. Higgins' Support Group, was a younger sister and namesake of the light antiaircraft cruiser sunk by a Japanese submarine in 1942 while retiring after the Battle of Guadalcanal. With a designed displacement of 6,000 tons, she had a speed of better than 33 knots and mounted a main battery of 16  5-inch dual purpose guns. The four ships of Captain Halle C. Allan's Destroyer Division 91--Mansfield, De Haven, Collett, and Swenson--were 2,200-ton, 35-knot ships of the Sumner class, completed in 1944 and mounting six 5-inch guns each.

          In addition to this small fighting force, ComNavFE controlled a variety of auxiliary ships. The most important of these were those of Amphibious Group 1, Rear Admiral James H. Doyle: the command ship Mount McKinley, the attack transport Cavalier and the attack cargo ship Union, LST 611, and the fleet tug Arikara.  This group, which held the tactical designation of Task Force 90 in the Naval Forces Far East organization, had recently arrived in Japan to conduct a program of amphibious training with units of the Eighth Army.

          A third category of force at Admiral Joy's disposal consisted of the units of Mine Squadron 3, which were engaged in check-sweeping World War II minefields.  Minron 3 contained six 136-foot, wooden-hulled, diesel-engined craft, and four 184-foot, twin-screw Admirable class AMs; but three of the latter were in caretaker status and the fourth, Pledge, in reduced commission. Finally, ComNavFE controlled a number of Japanese-manned ships belonging to the Shipping Control Administration, Japan--Scajap--which were employed in logistic support of the occupation and in repatriation of former Japanese prisoners of war from the continent of Asia.

          The activities of Admiral Joy's headquarters, like those of the forces it controlled, had been limited to the peaceful routine of an occupation force. The staff totaled only 28 officers and 160 enlisted men. There were four officers in the operations section, five in plans, four in communications. Since the activities of naval aviation in the Western Pacific were centralized at Guam, the NavFE staff had no air or aerology departments. Although two officers qualified in mine warfare were authorized, none was aboard. Like everyone else in the armed services, Commander Naval Forces Far East had based his plans on the assumption of a major conflict with the Soviets which would be centered elsewhere. The operation plans in effect in June of 1950 were concerned with such matters as passive defense, security under air attack, and the evacuation of American citizens in emergency.

          Naval base facilities in Japan were minimal. There was no logistic command, no representative of Service Forces Pacific Fleet to plan, coordinate, or procure. At Fleet Activities, Yokosuka, there was a minor ship repair facility which could perform routine upkeep, but which lacked specialized shops for torpedoes or for electronics repair; a supply section adequate to the support of the roughly 5,000 naval personnel and dependents in Japan and Japanese waters; an ordnance facility with some 3,000 tons of ammunition; and a naval hospital whose capacity had recently been reduced to 100 beds. At Sasebo in western Kyushu, where the Imperial Japanese Navy had formerly maintained a major base, there was an excellent harbor with extensive drydocking facilities. But other equipment was at a minimum, and the on-board complement was only 5 officers and 100 enlisted men. And neither Yokosuka nor Sasebo was well supplied with the material for underwater harbor defense.

          The single naval air base in Japan was the Naval Air Facility, Yokosuka, which supported two or three flying boats loaned by the Seventh Fleet for search and rescue missions. NAF Yokosuka had been but recently commissioned, rehabilitation of the buildings was still underway, only about five percent of the area of the former Japanese seaplane base was Navy-controlled, and Eighth Army was using the landing strip as a park for vehicles. As for land-based naval aviation, its total strength in Japan consisted of one target tow plane for antiaircraft gunnery training.

          Fortunately, however, Task Force 90 and Task Force 96 were not the only naval units in Asiatic waters.  Based in the Philippines, 1,700 miles to the southward, and under the command of Vice Admiral Arthur D. Struble, there lay the Seventh Fleet, the principal embodiment of American naval power in the Western Pacific. Yet while rejoicing in the title of fleet, Struble's command, in Second World War terms, amounted to little more than a few small task units. There was a carrier "group" with its screen, a submarine group, the two patrol plane squadrons of Fleet Air Wing 1, an evacuation group concerned with the safety of American citizens in emergency, and a variety of minor supporting units. The logistic group, which contained a small station reefer, a destroyer tender, and an oiler on shuttle service, constituted the total mobile fleet support in the Western Pacific, and was hard pressed to supply even the small Seventh Fleet.

          The Fleet's principal base of operations was on the island of Luzon, where the Navy, following the war, had developed new facilities at Subic Bay and an airfield at Sangley Point. Peacetime operations of the Seventh Fleet were under the control of Commander in Chief Pacific Fleet, Admiral Arthur E. Radford, but standing orders provided that, when operating in Japanese waters or in the event of an emergency, control would pass to Commander Naval Forces Far East. There were, however, certain problems implicit in this arrangement: Admiral Radford's area of responsibility included potential trouble spots outside the limits of the Far East Command; lacking an aviation section on his staff, the control of a carrier striking force and of patrol squadrons would present problems for ComNavFE; Admiral Struble was senior to Admiral Joy.

          Although early postwar policy had called for the maintenance of two aircraft carriers in the Western Pacific, the reductions in defense appropriations had made this impossible: for some time prior to January 1950 no carrier had operated west of Pearl; current procedure called for the rotation of single units on six-month tours of duty.  In these circumstances Admiral Struble's Seventh Fleet Striking Force, Task Force 77, was made up of a carrier  "group" containing one carrier, a support "group" containing one cruiser, and a screening group of eight destroyers. The duty carrier in the summer of 1950 was Valley Forge, an improved postwar version of the Essex class, completed in 1946, with a standard displacement of 27,100 tons, a length of 876 feet, and a speed of 33 knots. Flagship of Rear Admiral John M. Hoskins, Commander Carrier Division 3, Valley Forge had reported in to the Western Pacific in May, at which time her predecessor, Boxer, had been returned to the west coast for navy yard availability. The 25th of June found Valley Forge, with the destroyers Fletcher and Radford, in the South China Sea, one day out of Hong Kong en route to the Philippines. Admiral Struble was in Washington; Admiral Hoskins, upon whom command of the Seventh Fleet had devolved, was at Subic Bay; the carrier's commanding officer, Captain Lester K. Rice, was acting as ComCarDiv 3.

          The air group of Valley Forge, Carrier Air Group 5, Commander Harvey P. Lanham, was the first in the Navy to attempt the sustained shipboard operation of jet aircraft. Its complement of 86 planes was made up of two jet fighter squadrons with 30 Grumman F9F-2 Panthers; two piston- engined fighter squadrons equipped with the World War II Vought F4U-4B Corsair; and a piston-engined attack squadron of 14 Douglas AD-4 Skyraiders. Over and above these five squadrons the group contained 14 aircraft, principally ADs, which were specially equipped and modified--"configurated" in current Navy jargon--for photographic, night, and radar missions. The fighter squadrons had enjoyed considerable jet experience prior to receiving their Panthers and moving aboard ship; the group as a whole had conducted extensive training in close support of troops with the Marines at Camp Pendleton, California.

          The submarine force under the operational control of Commander Seventh Fleet, administratively organized as Task Unit 70.9, consisted of four fleet submarines and a submarine rescue vessel; its principal activity had been in antisubmarine warfare training exercises with units of the Fleet and of Naval Forces Far East. One of the four boats, Remora, was at Yokosuka on loan to ComNavFE; Cabezon was at sea en route from the Philippines to Hong Kong; Segundo, with Commander Francis W. Scanland, the task unit commander, was at Sangley Point in the Philippines; Catfish was at Subic Bay. The submarine rescue ship Florikan was at Guam, where she was about to be relieved by Greenlet. No submarine tender was stationed in the Western Pacific, but limited quantities of spare parts and torpedo warheads were available from the destroyer tender Piedmont at Subic Bay.

          Patrol plane activity in the Western Pacific, another Seventh Fleet monopoly, was centralized at Guam under control of Commander Fleet Air Wing 1, Captain Etheridge Grant, who served also as Commander Task Unit 70.6 and Commander Fleet Air Guam.  For long-range search and reconnaissance in the theater Captain Grant had at his disposal two squadrons of patrol aircraft. Patrol Squadron 28, a heavy landplane squadron with nine PB4Y-2 Privateers, the single-tailed Navy modification of the Liberator, was based at Agana, Guam. At Sangley Point, Luzon, Patrol Squadron 47 operated nine Martin PBM-5 Mariner flying boats. In addition to these two squadrons and their supporting organizations, Fleet Air Wing 1 had a small seaplane tender, Suisun, which on 25 June was moored in Tanapag Harbor, Saipan.

          For Captain Grant the impending crisis would not prove wholly unfamiliar, for the outbreak of war in December 1941 had found him commanding a seaplane tender in the Philippines. But his situation on 25 June was a somewhat scrambled one, for a second Mariner squadron, VP 46, was moving into the area as relief for VP 47, and the take-over process had already begun. Homeward bound, their tour in distant parts completed, the PBMs of VP 47 were widely dispersed. Two were at Yokosuka on temporary duty with Commander Naval Forces Far East,  two were at Sangley Point, two were in the air and on their way, and three had already reached Pearl Harbor.

          Such then was America's Western Pacific naval strength in June of 1950. Combat units assigned to ComNavFE and Commander Seventh Fleet totalled one carrier, two cruisers, three destroyer divisions, two patrol squadrons, and a handful of submarines. Not only was this a limited force with which to support a war on the Asiatic mainland: its southward deployment, with the principal base facilities at Guam and Luzon, made it ill-prepared for a campaign in Korea.

          Yet if forces, bases, and plans alike seemed inadequate to the challenge of Communist aggression, there were certain mitigating factors. To employ force, whether for police action or for war, on the far side of an ocean, is to conduct an exercise in maritime power for which fighting strength, bases, and shipping are essential. Unplanned for though the emergency was, a sufficient concentration was still possible. The occupation forces in Japan contained a large fraction--four of ten Army divisions--of American ground strength. FEAF's air strength was by no means inconsiderable. Naval forces in the Far East could be reinforced, from the west coast in the first instance, in time from elsewhere. Limited though the fleet bases were in the narrow sense, in the larger context the base was Japan, and the metropolis of Asia offered many advantages in the form of airfields, staging areas, industrial strength, and skilled labor.  Additionally, and by no means least, there existed and was available a sizable Japanese merchant marine, which could help to provide the carrying capacity without which control of the seas is meaningless, and which could be employed to project the armies and their supplies to the far shore.

          The war in Korea, moreover, was in a sense a suburban war, and one must go back to 1898 to find in the American experience a parallel to this proximity of base and combat areas. The distances between Key West and Cuba and between Sasebo and Pusan are much the same. It could be argued, perhaps, that Admiral Joy's situation presented certain parallels to that of Admiral Cervera, but there was at least one notable difference: in 1950, despite the withdrawal of the entire occupation force, the populace of Japan proved reliable; in 1898, despite the presence of a Spanish army, the populace of Cuba did not. Doubtless to the Communists Korea seemed the most promising spot for aggression. In many ways it was also the area where the United States could best extemporize a reply.
