Dear Mr. Wheeler,
Thank you for posting your request on History Hub!
The "official" photograph of an individual is not considered to be permanent federal records by the respective military services and is not retained in a separate collection by the service. If the photograph you are seeking still exists, it will most likely be found in the individual's Official Military Personnel File (OMPF). However, there is no guarantee the photograph will be present. Using the information from the previous poster, People - Port Chicago Naval Magazine National Memorial (US National Park Service), we suggest that you request the OMPFs that you seek. Please complete a GSA Standard Form 180 for each person and mail them to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002.
Due to the COVID-19 pandemic, NPRC will continue servicing requests ONLY associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
Also, we searched the National Archives Catalog and located 81 file units & 6 items that pertain to the Port Chicago Explosion that have been digitized. They may include photographs or moving images of those who were killed in the explosion. For access, please on the above link and select the file unit of interest.
We hope this is helpful. Best of luck with your research!
