Abstract: This paper introduces the general situation of the combat system for surface combatant ships and reviews the development process of DDG combat system in China. It presents some directions of com-bat system in future,including 1)To achieve well-designed performance of platforms and payloads;2)To optimize the architecture of combat systems by applying the Total Ship Computing Environment(TSCE) compliant in Open Architecture(OA),promoting the new software integration mode;3)To advance the interface design and data integration with XML and data bus technology,including Data Distribution Ser-vice(DDS)middleware and Enterprise Service Bus(ESB);4)To develop software according to Ser-vice-Oriented Architecture(SOA)and cloud computing;5)To improve telecommunication for the imple-mentation of cooperative engagement.
