The USS S-16
(SS-121) was an S-boat, commissioned in 1920. She was the largest
submarine the U.S. Navy operated in that period. The new vessel was was
designed submerge to depths as deep as 200 fsw. The S-16 served in
the Pacific fleet until 1935 but was recommissioned in 1940 as World War
II loomed. She patrolled the Caribbean until considered obsolete in
1944. In 1945 the S-16 was finally sunk as a target off of Key
West, FL. in 1945. She now rests upright in 255 fsw, a depth deeper than
her original maximum dive depth.
