Air Operations in the Taiwan Crisis of 1958 is one of a series of studies on air operations in international incidents, prepared by the USAF Historical Division Liaison Office at the request of the Directorate of Plans, Headquarters USAF. Thishistorical narrative, by Jacob Van Staaveren, is based on primary source materials available in 1960--messages and correspondence--and on histories from many levels of the Air Force, including units, commands, and the Air Staff. Originally prepared in a very few copies, the study has been in great demand by the Air Staff, major commands, and Department of Defense agencies and is now being published for wider dissemination.The defense of Taiwan has been and will continue to be a source of major concern to the United States and especially to the U.S. armed services. It is likely that there may be more military crises involving Taiwan and its related islands. The crisis in 1958 provided a test of American military planning concepts that should prove of value for future planning. Occurring in the Pacific almost simultaneously with the Lebanon crisis of July-August 1958, it created certain planning, operational, and logistic problems that had not been anticipated.
