Technical Effectiveness Considerations on the Replacement of Missiles with Interceptor UAVs.

This article examines the technical effectiveness and cost-efficiency of replacing intermediate-range missile (IRM) interceptors with reusable unmanned aerial vehicle interceptors (UAVIs) equipped with automatic cannons and booster rockets. Using scaled-down models of existing fighter aircraft such as the F16 and F104, the study proposes UAVIs capable of engaging multiple low-cost threats like drones, rockets, and missiles at ranges up to 70 km, with significantly reduced per-interception costs compared to traditional IRMs. The UAVIs employ off-the-shelf components including jet engines, targeting systems adapted from IRM technology, and various weaponry options (12-gauge, 5.56 mm, and 84 mm cannons) to provide flexible mission profiles including air defense, close air support, and precision strikes. Simulation results indicate that UAVIs can achieve comparable or superior maneuverability and interception capabilities against subsonic and slightly supersonic threats, while offering reusable and economically sustainable defense solutions. The study emphasizes integration with existing missile defense systems and highlights the potential for rapid deployment using commercially available radio-controlled aircraft platforms and mature weapon technologies.
