The Submarine Service has lost many dedicated men to individual tragedies -- men  who were lost while serving on vessels that were not sunk.  They, too, have made the ultimate sacrifice in the relentless struggle on and under the sea.  

Not all of the men on these pages were actual members of submarine crews. Examples of submarine passengers who did not return from their missions are the UDT men carried on USS Burrfish, and the Australian Special Operatives with Z Special Unit carried on USS Bream.

Men who were lost in non-sinking events whose vessels were later lost are included with their shipmates on the individual boats' pages.

The 26 men who died in the battery fire on USS Bass (SS-164) are listed on an individual page.
