This opportunity seeks development and deployment of effective Counter-Unmanned Underwater Vehicle (C-UUV) defeat solutions to neutralize threats from malicious UUVs used for intelligence gathering, smuggling, and sabotage. The focus is on fielding defeat and mitigation systems, as detection technologies already exist but few tested solutions are available for stopping UUV threats. The goal is to enhance maritime domain dominance, port security, and critical infrastructure protection. No specific budget amounts, performance location, or non-bid timelines are mentioned in the description.
