MIUWU 201

Mobile Inshore Undersea Warfare Unit 201 (MIUWU 201) was a naval reserve unit within the United States Navy, specializing in coastal surveillance and harbor defense operations. Established during the Cold War era, MIUWU 201 was tasked with detecting and monitoring underwater threats in littoral environments using mobile sensor and communications equipment. The unit regularly participated in joint exercises and operations, providing critical security for ports, anchorages, and high-value maritime assets. MIUWU 201 contributed to both national defense and international missions until its decommissioning as part of broader Navy force restructuring in the early 21st century.
