The Department of Defense, specifically the U.S. Army Contracting Command at Redstone Arsenal, is seeking information on small form factor component technologies for a Counter-Small Unmanned Aircraft System (C-sUAS) interceptor through a Request for Information (RFI). The objective is to gather data on existing missile component technologies, including seekers, Control Actuation Systems (CAS), batteries, and Guidance Navigation Units/Inertial Measurement Units (GNU/IMU), that meet specific performance and production criteria, such as a Technology Readiness Level (TRL) of 5 or greater and compatibility with missile diameters of 40mm to 70mm. This initiative is crucial in addressing the evolving threats posed by small unmanned aircraft systems in modern warfare, aiming to enhance the Army's capabilities in missile defense. Interested parties must submit their responses, including a technical white paper and an Excel data sheet, by 11:00 AM CST on December 19, 2025, to the primary contact, Ms. Tammy J. Benson, at tammy.j.benson.civ@army.mil.
