Classification 99: Plant Surveys

The FBI established this classification and with it assumed responsibility for ascertaining the protection capabilities and weaknesses of defense plants. Each plant survey was a separate case file, with the survey, supplemental surveys, and all communications dealing with a plant insofar as plant protections was concerned all filed together. On June 1, 1941 and January 5, 1942 the Navy and Army (respectively) assumed responsibility for surveying defense plants in which they had interests. Thereafter, FBI involvement in plant surveys was minimal.
