The Defense Acquisition Board is the senior advisory board for defense acquisitions in the United States Department of Defense. The board includes the Vice Chair of the Joint Chiefs, the service Secretaries, and a number of Undersecretaries of Defense. The DAB plays an important role in the Defense Acquisition System. Members of this board are responsible for approving the Major Defense Acquisition Programs (MDAPs) and serve as the most important executive review of expensive acquisition projects that would have potentially large impacts on how wars are fought — things like new tanks, fighter aircraft, or C3 systems. See DoD Defense Acquisition Guidebook for more information on the process.
