Vandenberg would remember that most of the discussion at the Sunday [6/25/50 EST] meeting was speculation about whether the Soviet Union or China might take a hand in the fighting. There was no argument or discussion about the difficulties that were going to be involved if the poorly prepared American armed forces were ordered into combat. However, one thing was certain: Vandenberg knew and frequently told listeners that the US Air Force was on trial in Korea. Based on his wartime experience as a foremost tactical air commander, Vandenberg had an interesting view of the unitary nature of air power. He had hoped to rid the Air Force of the arbitrary separation of combat units into "tactical" and "strategic" forces. In Korea, strategic B-29 bombers were going to deliver the heaviest blows against the Communist invaders.
At the outbreak of the war, General Headquarters (GHQ),
US Far East Command (FEC), in Tokyo had no combat mission relevant to the Republic of Korea.
The Far East Air Forces (FEAF) was geared for air defense provided by the Fifth and Thirteenth Air Forces. FEAF had, however, managed to retain the Twentieth Air Force with one B-29 wing on Guam.
This unit was the 19th Wing, and it was the only strategic wing not assigned to Strategic Air Command. In an expedited movement, the 19th Group's air echelon immediately moved to Kadena Air Base on Okinawa, from which location an Army staff group in GHQ undertook to direct its employment in support of friendly ground forces in Korea.
The effort to manage the B-29's from GHQ as somewhat successful. For an initial strike, aircraft were loaded with fragmentation bombs and directed to hit Red aircraft at Wŏnsan. The strike was diverted to attack Han River bridges at Sŏul, where the frags were virtually useless. In the days that followed, the B-29 crews were ordered to search out and bomb enemy tanks. Another mission was ordered out to destroy bridges at coordinates on a supposed east coast rail line. This task was difficult since the rail line, though shown on a map consulted, had never been built.
