System dynamic evolution is a cognitive foundation of structure optimization and effectiveness evaluation for formation system of systems (SoS). In view of entity heterogeneity of the formation, coupling of the system, and emergence of combat SoS, the paper firstly summarizes the evolution characteristics of surface ship formation. The evolution features are summarized from four aspects:information drive, function emergence, structural time change and overall correlation. Secondly, the elements of formation SoS are abstractly analyzed. The battle of surface ship formation is divided into two stages, prewar growth and war confrontation, for architecture abstraction. Thirdly, a hypernetwork model of formation SoS is established, and the conceptual model and structure model of the hypernetwork are established from different perspectives. Lastly, task driven progressive evolution modeling and information driven radical evolution modeling based on hypernetwork are proposed. The evolution model is given calculation method of formation SoS. According to calculation example of formation combat, the evolution model can effectively describe the process of formation SoS combat dynamically and provide strong support for formation structure optimization and effectiveness evaluation.
