Dear Mr. Stevenson,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located 110 record series from the 1960s that relate to intelligence and were created by various components of the US Navy. For more information, please contact the National Archives at College Park - Textual Reference (RDT2) at Archives2reference@nara.gov.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
Additionally, a number of records relating to Naval intelligence and Vietnam are in the custody of the Naval History & Heritage Command (NHHC). Please write to the Operational Archives Branch, Naval History & Heritage Command, 805 Kidder Breese Street, SE, Washington Navy Yard, Washington, DC 20374-5060 or contact them via email at firstname.lastname@example.org. Their website is https://www.history.navy.mil/research/archives.html.
We hope this is helpful. Best of luck with your research!
