In order to manage the complex large-scale systems engineering of technical support of warship equipment, a method was provided to identify and refine the object of technical support combined with the features of integration, systemic, and complexity for technical support capacity building. The trends and requirements of army-civilian support were analyzed to establish the task deconcentration model, which is based on the degree of standardization, technological, unilizational, and support risk. The management framework and road-map were dicussed according to systematic capacity architecture. The engineering application shows that the programing can be adapted to requirement of technical support of warship equipment in new situation, which can keep the operational availability. It promotes the formalization and standardization of engineering management to enhance the quality and effect of technical support.
