Stratospheric airships have emerged as ideal platforms for persistent reconnaissance, surveillance, air defense, missile defense, electronic warfare, and communication relays in military applications, garnering significant attention both domestically and internationally. Addressing the efficacy evaluation requirements of the stratospheric airship, this study begins by analyzing scenarios involving anti-stealth penetration operations, meticulously delineating the interaction processes of various equipment, and distilling the key capabilities of the stratospheric airship. Subsequently, employing the ABMS (Agent-Based Modeling and Simulation) method, stealth aircraft, anti-aircraft missile, ground radar, and other equipment are abstracted as intelligent agents to construct a simulation platform for stealth aircraft penetration and counteraction. Finally, interception rate and average distance of first lock-on are selected as evaluation metrics to investigate the changes in evaluation criteria with and without the presence of stratospheric airships, thereby achieving the goal of assessing the operational effectiveness of stratospheric airships.
