The Department of Defense, specifically the U.S. Navy, is seeking innovative solutions to delay and deny access to its assets from unauthorized Unmanned Underwater Vehicles (UUVs). The objective is to develop a system capable of neutralizing small and medium-sized UUVs, defined as having a diameter of no more than 21 inches, at depths of up to 800 feet, ensuring they can only travel a limited distance before being rendered ineffective. This initiative is critical for enhancing naval security and protecting sensitive underwater areas from potential threats. Interested parties should note that the solicitation is set to open on April 23, 2025, with a closing date of May 21, 2025, and can find more information at the provided source link: https://www.dodsbirsttr.mil/topics-app/.
