Abstract: Software-defined warfare is a new operational concept that leverages interconnected software platforms for analysis, planning, and control to achieve systematized operations. To address the application challenges of software-defined concepts in unmanned aerial vehicle（UAV）swarm operations, this paper constructs a real-time simulation and validation system. The system integrates large-scale multi-task scenario management, distributed network simulation, event-triggered and task-driven autonomous decision-making and planning, six-degree-of-freedom simulation, and visual simulation. By designing diverse operational scenarios for heterogeneous UAV swarms and validating them through dynamic event triggers and state transitions, the system's effectiveness is confirmed. It overcomes
limitations in the number of simulated UAV platforms, enables on-demand configuration of multi-task scenarios, and enhances the intelligence level of UAV swarms.
