Abstract: In this paper, the dynamic integration model of time-sensitive strike chain in naval battle field is studied. Firstly, the typical combat platforms and elements related to cross-domain cooperative operations in naval battle field are abstracted into four types of resource nodes: detection, processing, decision-making and strike, and the process of strike chain is modeled and described by directed network. Then, with the shortest time delay as the goal, the constraints such as wide combat space, low transmission rate between nodes and limited communication distance are considered. The mathematical model of dynamic integration optimization of strike chain is established. Then the typical scenario of air defense if designed to demonstrate the shortest delay analysis of the strike chain and the destruction reconstruction analysis. The example shows that the model can successfully optimize the minimum delay of the strike chain, and can reconstruct strike chain when the node is missing or attacked. The example also quantitatively describes the changes of the minimum delay and cover sector index of the reorganized strike chain under the countermeasure condition. Finally, a typical attack of Black Sea Fleet by Ukrainian unmanned cluster is presented. An example is constructed to analyze the ability of the ability of the Black Sea Fleet to resist the unmanned cluster attack of Ukraine based on the strike chain model. The simulation results show that the formation of the Black Sea Fleet is scattered and the coordination ability is poor in the original berth state. After holding a certain formation, the anti-saturation attack ability has been improved. This paper verifies the feasibility of naval warfare analysis base on strike chain model, which can provide theoretical model support for the design of future maritime joint combat system oriented to kill net.
