Abstract: The joint application of multi-element of air-ground coordination combat, the construction requirements for kill chain dynamics are focused on， the construction scheme design of air-ground distributed coordination soft bus with networked loose coupling features is carried out. Based on such requirements as reliable transmission of tactical commands, efficient distribution of situation information, service management and control of combat resources, agility and adaptability of collaborative actions,etc. Such key technical breakthroughs are completed including integrated coordination network of network chain, cross-network information distribution, distributed data management, multi-node coordination service scheduling and dynamic construction of kill chain. The multi-element information interoperation and coordination combat capability in air-ground is effectively improved in construction practice.
