The Interment Card for his burial at Arlington National Cemetery has a penciled notation that I believe is his Service Number which would be helpful if you request his service records. He was a Naval Aviation Cadet and the number on the card is 4473696.
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports of officers of the U.S. Navy who were separated from service after 1902 and prior to 1958 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. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Navy and Marine Corps casualty records from 1940-1989 are in the custody of the National Archives at St. Louis (RL-SL). For access to these records, please contact RL-SL via email at email@example.com.
The National Archives at College Park - Textual Reference (RDT2) has custody of aircraft accident reports for the World War II period among the general correspondence of the Records of the Bureau of Aeronautics (Record Group 72). Aircraft accident reports provide information about accidental losses of Navy aircraft; they do not usually include information about losses of aircraft as a result of Navy war operations or combat engagement. To obtain a copy of any existing records, please provide us with the complete Navy aircraft model number (e.g. F4U-1A, PB4Y, SNV-1) and the date it was lost and/or the date it was reported lost. Also provide the geographic location of the loss if possible. Please email RDT2 at: firstname.lastname@example.org with the information.
In addition, you can locate U.S. Navy aircraft accident reports from 1920 through 1969, from the Naval Aviation History Branch, Naval History & Heritage Command, 805 Kidder Breese Street, SE, Washington Navy Yard, Washington, DC 20374-5060. The reports are a record of operational losses and normally do not include combat losses. Requesters must have the type of aircraft and date of the accident in order to obtain a copy of the report, which are available only on microfilm.
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 and RL-SL. Also, the NPRC closed again as of November 7, 2020 until further notice. NPRC will respond only to requests involving burials, medical emergencies, and homeless veterans. If your request is urgent, please see Emergency Requests and Deadlines or emergency requests may be faxed to (314) 801-0764. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for any inconvenience.
We hope this is helpful. Best of luck with your family research!
