Without any details about the badges, we would suggest doing some online searches of navy patches, badges and insignia to see if you can find a match. There are quite a few resources online that have comprehensive lists that include images. Feel free to post more details about the patches here if you want help identifying them.
If you’re trying to find more information about his service you may want to request his Official Military Personnel Files from the National Personnel Records Center. Note that due to the COVID-19 pandemic, the NPRC has been closed and only completing emergency requests. As of March 8, 2021, the NPRC entered into a phased expansion of our onsite workforce. They are continuing to increase their on-site staffing and are servicing requests associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. For that reason you want to refrain from submitting non-emergency requests until they return to pre-COVID staffing levels. You can check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for any inconvenience.
We hope this information helps you get started with your research. Best of luck!
