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.
