Abstract: Kill web represents an advanced concrete manifestation of joint operations supported by network-centric information systems, embodying intricate interrelationships. These relationships are pivotal in determining its operational effectiveness. Based on a detailed analysis of functional coupling relationships, information interactions relationships, and command and control relationships, this study proposes a "function-information-coordination" kill web model. Operational modes derived from this framework are analyzed, followed by a case study of the India-Pakistan air combat scenario. The findings provide valuable references for subsequent theoretical research and engineering development of kill web.
