Dear Ms. Montuya,
Thank you for posting your request on History Hub!
To seek your father’s records, we suggest you begin by requesting his Official Military Personnel Files (OMPF). OMPFs and medical records of enlisted men and officers of the U.S. Navy who were separated from the service after 1956 and prior to January 31, 1994 are located at NARA's National Personnel Records Center (NPRC), (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. To request these records, please mail a completed GSA Standard Form 180 to NPRC. Certain information in the records is not available to the general public without the written consent of the veteran or his next of kin.
Additionally, for operational records of your father’s unit, please contact the Naval History and Heritage Command. The records would be under either Task Force 116, River Patrol Squadron 5, or Task Force 194 - SEALORDS.
We hope this is helpful! Best of luck with your family research!
