Sub Memorial - On Eternal Patrol
Honolulu, Oahu, Hawaii
The thing about any World War II sub lost at sea: more times than not, it was really lost. As in never found. The USS Arizona is an enduring monument to World War II sacrifice, partly because the Japanese had the forethought to sink that battleship in shallow water so they could see it as tourists later.
Not so with subs. The ones we tour in ports and military parks all made it home. Hundreds more went down, due to accidents, mines, enemy action. 3,500 American submariners never returned. At Pearl Harbor, there's a memorial park with a circular arrangement of tombstone-like granite monuments to specific World War II subs sunk, lost, and never heard from again.
Each monument includes a photo of a submarine and a summary of its wartime service history before going off the scopes. A list of officers and crew are "on eternal patrol."
The USS Bowfin, which made it home, sits nearby in the harbor and is open for tours.
