This is a Request for Information (RFI) seeking vendors capable of providing Counter-small Unmanned Aircraft Systems (C-sUAS) capabilities, specifically for detection and low-cost defeat solutions. The RFI requests feedback on a provided Software Development Kit (SDK) and information on Proliferated Low-Altitude Detect and Low-Cost Kinetic Defeat technologies, with vendors able to respond to any combination of these three parts. The purpose is to identify potential vendors for a demonstration event in late May 2026. Responses must be submitted via email to the specified USAF contacts. This is for planning purposes only and does not constitute a formal solicitation.
