US Coast Guard seeks tech to detect and defeat uncrewed underwater vehicles

The USCG issued a request for solutions for systems that can not only detect/track uncrewed underwater vehicles (UUVs) but also defeat/mitigate them, especially for port and harbor defense. While not a fielded weapon yet, it signals an emerging counter-UUV capability area (sensors + interdiction/kill chain) driven by recent combat use of UUVs against high-value naval targets.
