Abstract: As a typical representative of defense acquisition,equipment acquisition usually involves large amount of processes in execution.Meanwhile,due to the advancement requirements of the equipment,its realization must rely on the effective integration of advanced scientific and technological achievements in many fields.Therefore,the impacts of technological maturity and manufacturing maturity on acquisition programs must be considered.For ensuring the success of acquisitions and managing the implementation effectively,the department of defense has proposed defense acquisition system based on system engineering methodologies,which is one of the three decision support systems utilized in defense acquisition.By dividing the entire life cycle into several phases,an acquisition program goes through solution analysis,technical maturity,engineering and manufacturing development,production and deployment,operations and support,and retire processing phases,with the technological and manufacturing maturity improves simultaneously.By setting the milestone decision points between acquisition phases,the achievements of current phase and the goals of the subsequent phase can be evaluated.In this manner,the acquisition execution and phase transition can be supervised effectively and the program risk can be reduced significantly,which can finally realize the capability requirements described in joint capabilities integration and development system as an equipment.As a result,this work will focus on the defense acquisition system,to illustrate the acquisition phases and their corresponding tasks systematically,and finally provide a sufficient support for the related work.
