The US Defense Acquisition System is the largest, and the most complex, rigorous, and steady system for the acquisition of military equipment in the world. It has made an outstanding contribution to maintaining the country’s military dominance. Under the guidance of its national defense strategy in recent years, the United States has accelerated the process of adjusting and improving its defense acquisition system to ensure the sustainable development of its technological advantage over the militaries of other countries. In 2020, the US Department of Defense summarized reforms to its acquisition system based on experience and lessons of the past, and made significant changes to the Department of Defense Directive 5000.01—“Defense Acquisition System.” First, this paper provides a brief background for this evolution. Second, it analyses the content of changes to the directive based on the two dimensions of policy and responsibility by exploring the relevant innovations and underlying philosophy to obtain insights into the trend of development of defense acquisition systems. Finally, the above analysis is used to formulate suggestions from four perspectives, including regulations and policies as well as the application of new technologies, to provide a reference for the acquisition of equipment by the Chinese military.
