On Eternal Patrol - Researchers

Since 2005, eleven lost U.S. Navy World War II submarines have been found, and our database has been instrumental in informing the families of the final resting place of their loved ones.

These are the people who are currently contributing much of their time and effort to perpetuate the memory of men lost while in the service of the U.S. Submarine Force.  To see a listing of others who have contributed greatly to this mission in the past, please see our Sources and Acknowledgements page.
