Abstract The Indirect Fire Protection Capability-High-Power Microwave (IFPC-HPM) system is a solid-state high-power microwave counter-unmanned aircraft system (counter-UAS) weapon procured by the U.S. Army from Epirus, designed for low-altitude air defense missions. The system has evolved to its second-generation variant and has undergone two experimental deployments in the Middle East and the Indo-Pacific region. Leveraging artificial intelligence-enabled control, the IFPC-HPM achieves digitally controlled waveform output and precisely defined kill zones, with the capability to defeat unmanned aerial vehicles hardened with electromagnetic shielding. This paper presents an overview of the IFPC-HPM system, encompassing its development background, evolution, operational principle, performance parameters, operational employment modes, and future development, offering reference for research in counter-UAS and high-power microwave domains.
