Navy Inshore Undersea Warfare Group Two (IUWG-2)

Navy Inshore Undersea Warfare Group Two (IUWG-2) was established as part of the U.S. Navy’s initiative to enhance harbor defense and coastal security, particularly during the Cold War era. IUWG-2 specialized in inshore undersea warfare operations, including surveillance, detection, and protection against underwater and surface threats to naval installations and anchorages along the East Coast of the United States and deployed locations. The group operated a combination of active and reserve personnel, utilizing advanced sonar, underwater sensors, and patrol craft to fulfill its mission. IUWG-2 played a vital role in safeguarding critical maritime assets until its functions were integrated into the Maritime Expeditionary Security Force in the early 21st century.
