In 2006 and 2007, two nuclear mishaps occurred that highlighted systemic breakdowns in the Air Force's nuclear enterprise. These two high-profile incidents triggered a series of reviews and investigations ordered by the Secretary of Defense and the Secretary of the Air Force. In report after report, the culture of the nuclear enterprise was identified as an area of concern and in need of improvement. Although it may take decades to see the ultimate results of culture change, this paper examines whether or not the Air Force is taking steps to change and improve the culture within the nuclear enterprise. A review of organizational culture research shows that to change an organization, leaders must first understand organizational culture and the organization's culture. This paper examines organizational culture and the culture of the Air Force nuclear enterprise. Reports identifying areas of concern related to Air Force nuclear culture were also examined.
