USAF Plans and Policies: R&D for Southeast Asia, 1968 is the eleventh of a series of historical monographs prepared by the Office of Air Force History on various aspects of the war in Vietnam. It is a continuation of a previous study on the same subject written by the author. In this narrative, Mr. Wolk reviews several critical investigations of Air Force research and development procedures and programs, examines the functioning of the Southeast Asia Operational Requirement system, and discusses USAF efforts to modify or develop new systems and equipment to counter the enemy's growing air defenses in North Vietnam. He also reviews steps taken by the Air Force to improve bombing accuracies and briefly discusses the major systems which were developed and deployed to the theater under Project Shed Light.
