The equipment and innovative application modes of the UAV swarms have brought new challenges to the defense and confrontation of the system. In order to achieve efficient and cost-effective balance of attack and defense, and effectively respond to the threat posed by UAV swarms. Taking airborne laser weapon anti UAV swarm as research object, the application scenarios of airborne laser weapon anti UAV swarm were systematically analyzed, stakeholders were identified, and the requirements of airborne laser weapon anti UAV swarm were captured. Provide top-level design input for the functional analysis, architecture trade-off, and design synthesis of airborne laser weapon anti UAV swarm. We have modeled and analyzed the requirements, functions, architecture, and integration of airborne laser weapon anti UAV swarm, providing effective support for technical research and project development of airborne laser weapon anti UAV swarm. The analysis suggestions for application of airborne laser weapon anti UAV swarm based on model have certain practical reference significance.
