The Department of Defense, specifically the U.S. Army's Combat Capabilities Development Command, is seeking innovative technology contributions through a Request for Information (RFI) for the Technical Support and Operational Analysis (TSOA) Defense-in-Depth Experiment (DiDEX) 25, focusing on counter-small Unmanned Aircraft Systems (C-sUAS) and other small unmanned systems (UxS). The objective of this initiative is to enhance warfighter capabilities in detecting, identifying, tracking, and neutralizing threats posed by small unmanned systems in urban environments, while addressing operational security and force protection challenges. This event, scheduled for Q1 FY26 in Austin, TX, will involve field experiments to evaluate the effectiveness of emerging technologies, with a deadline for white paper submissions set for June 20, 2025. Interested parties can reach out to Samual Newberry at C5ISR-Experimentation@army.mil for further information.
