The purpose of this research was to explore the corporate social responsibility orientation (CSRO) of managers of firms that manufacture command, control, communications, computer, intelligence, surveillance and reconnaissance (C4ISR) equipment and have contracts with the Department of Defense. A total of 1082 managers were invited to participate in this study. The findings from this study identified that these firms have a stronger concern for the legal and economic domain than Aupperle's (1982) original research, yet their corporate social responsibility orientation scores fall within the norms of other industries, based on prior research. Four known independent demographic variables of corporate social responsibility orientation (CSRO) affected only the economic domain of the firms surveyed. The Federal Acquisition Regulation was found to constrain the corporate social responsibility orientation in the discretionary domain.
