Abstract In view of the current operational background of the development of air attack system towards the integration of sky, ground, sea, network and electronic, and the expansion of operational airspace to near space, outer space and network electronic space, the paper points out the connotation and core content of the integrated air defense cooperative networking operation, analyzes the current situation at home and aboard, proposes the composition of integrated air defense cooperative networking operation, studies the technical approach of adaptive networking architecture, integrated fire control network, distributed command and control system, operational component, discusses its combat capability, combat style, typical scenario and operational process. The operation technology can provide a useful reference for realizing the cross domain networking operation of interconnection and interoperability between different types defense equipment and establishing the integrated aerospace defense system.
