Counter Uncrewed Underwater Vehicles (C-UUV) Defeat Technologies

The Department of Homeland Security, through the Office of Contract Operations within the U.S. Coast Guard, is seeking innovative solutions to counter emerging threats posed by uncrewed underwater vehicles (UUVs) through the solicitation titled Counter Uncrewed Underwater Vehicles (C-UUV) Defeat Technologies. With UUVs becoming more accessible and capable, they are increasingly exploited for covert intelligence collection, infrastructure sabotage, smuggling, and direct kinetic attacks, presenting significant challenges to maritime security due to their stealth and advanced navigation systems. Current detection technologies exist, but there is a critical gap in tested, fielded defeat mechanisms that can effectively neutralize these threats once identified, making the development and integration of reliable C-UUV defeat systems essential to enhancing maritime domain dominance, port security, and the protection of critical underwater infrastructure. This sources-sought notice, issued under NAICS code 928110 and identified by solicitation number 70Z02326RFI0005, invites industry and research entities to submit capabilities that can detect, track, and actively defeat hostile UUVs. The response deadline is August 7, 2026, and proposals must align with operational needs in environments such as New London, Connecticut, a key location for maritime security operations. The primary point of contact for inquiries is Kiemisha Sweetney of the U.S. Coast Guard, reachable at smb-comdt-coco31acquisitions@uscg.mil. The initiative reflects an urgent national priority to close capability gaps in undersea defense and ensure a robust, layered response to asymmetric underwater threats before they can cause harm to national security assets or civilian infrastructure.
