Air and space offense and defense determine the main direction of war. Air and space defense is the main battlefield of air and space offense and defense operations. Kinetic energy interception hard damage is the main combat mode of air and space defense. The development of kinetic energy interception weapon capabilities involves national strategic interests and air and space security. The development trend of kinetic energy interception weapons was analyzed. The generation mode of operational requirements for kinetic energy interception weapons， the integration method of advanced technologies， the engineering design implementation mode and the analysis framework of the coupling model were constructed. The interaction relationship at each coupling level， the iterative evolution path and other capability development logics were briefly expounded. Based on the coupled model of kinetic energy interception weapon capability development， the current development status and progress of advanced technologies and key solutions related to capability development are sorted out and analyzed in a focused manner. It can provide a reference for improving the quality and speed of the development and evolution of kinetic energy interception weapons， and may have certain reference value for researchers related to kinetic energy interception weapons in air and space defense.
