Office of Naval Intelligence, Naval Investigative Service, Regional Office 0893 (NCIS)

The Office of Naval Intelligence (ONI), established in 1882, is the United States Navy’s oldest intelligence organization, dedicated to collecting, analyzing, and disseminating maritime intelligence. In 1966, the Naval Investigative Service (NIS) was formed as a branch of ONI to address criminal, counterintelligence, and security matters within the Navy and Marine Corps. Regional Office 0893 was one of several field offices under NIS, providing local investigative and counterintelligence support to naval installations in its assigned area. In 1992, NIS was reorganized and renamed the Naval Criminal Investigative Service (NCIS), inheriting the responsibilities and regional structure, including the duties once performed by Regional Office 0893.
