The Naval Undersea Warfare Center (NUWC) is the United States Navy's full-spectrum research, development, test and evaluation, engineering and fleet support center for submarines, autonomous underwater systems, and offensive and defensive weapons systems associated with undersea warfare. It is one of the corporate laboratories of the Naval Sea Systems Command. NUWC is headquartered in Newport, Rhode Island and has two major subordinate activities: Division Newport and Division Keyport in Keyport, Washington. NUWC also controls the Fox Island facility and Gould Island. It employs more than 4,400 civilian and military personnel, with budgets over $1 billion.

The current entity is composed of many elements of Navy undersea research, particularly acoustics and acoustic systems with weapons research and development history dating to the 19th century. Two major laboratories, in Newport and New London composed the largest elements of what is now Division Newport. Those laboratories were themselves made up of consolidated older laboratories and facilities dating from World War I.
