US Marine Corps selects AI-powered Bullfrog autonomous weapon system for drone defense

Allen Control Systems announced on July 21, 2026, that the US Marine Corps has selected the Bullfrog autonomous weapon system for integration into its Ground Based Air Defense (GBAD) program. The AI-enabled system automatically detects, tracks, and fires against aerial drones using an M240 machine gun, with a claimed cost-per-kill as low as $10. The Marine Corps plans to incorporate Bullfrog into its Light Marine Air Defense Integrated System (L-MADIS), which currently relies on electronic warfare. The system is already used by the Army and Navy and has been approved by the Pentagon's Joint Interagency Task Force 401. The decision comes amid growing concerns over the economic imbalance of using expensive interceptor missiles against cheap drones, highlighted by conflicts in Ukraine and the US war with Iran, where Shahed drones cost around $35,000 compared to $4 million interceptors.
