|On Eternal Patrol - Submarine Losses - Chronological|
USS S-28 (SS-133), lost off Oahu, Hawaii, on July 4, 1944
The following American submarines have been lost since 1900, listed chronologically by date of loss. When the date of loss is not precisely known, a "best guess" date is given. See also our Lost Submarines by Month page.
The "Men Lost" column below lists only the number of men who died as a result of the sinking, including passengers (civilians, foreign nationals, and Army personnel), as well as men who later died as POWs. These figures do not include men lost in events that occured prior to the loss of the vessels. However, those men are included with their shipmates on the pages for the individual submarines linked to below.
If the numbers of men lost as shown on this page appear to conflict with those found on other sources, please see our Discrepancies in Numbers of Lost Submariners page for further information.
Please view the "Additional Losses" pages for listings of men were lost while serving on vessels that were not sunk. The 26 men who died on USS Bass (SS-164) are listed on an individual page.
*One man was killed by enemy gunfire 12 days before the boat was lost on the same patrol. If he is included, the number of men lost with Amberjack would be 73.
A case could be made for including a number of other submarines on this list:
"USS" Alligator (Civil War - never actually commissioned) - under tow and unmanned, set adrift in a storm and presumed to have sunk near Cape Hatteras, North Carolina, on April 2, 1863.
