In order to effectively detect, identify, and counter small unmanned aerial vehicles, this study investigates the current status, development priorities, trends, and paths of the US military's unmanned aerial vehicle countermeasure equipment capabilities. By distinguishing seven categories including comprehensive accusation, target detection, electronic interference, laser strike, microwave strike, network capture, and firepower strike, a systematic and comprehensive analysis was conducted on the current status of the countermeasure equipment capabilities of over 160 types of unmanned aerial vehicles in the US military, and 25 typical representatives were selected for in-depth analysis. Analyze from the perspectives of top-level planning, equipment development, technological exploration, and experimental verification, and propose development insights and suggestions. The results indicate that the suggestion is enlightening and can provide readers with learning and reference.
