World War II specifications and design details for the
U.S. Navy S-Class submarines



S-Class submarines
 

 

The oldest of the submarines to see combat action in the Pacific, this post World War I vintage boat was certainly not designed for the type of war in which they were engaged against Japan. Originally employed as a fleet "scout" for operations in the Atlantic, these "Pigboats" were reluctantly pressed into service during the early days of the war against Japan due to the U.S. Navy's severe shortage of fleet boats. Old, obsolete, underpowered with limited range and inadequately armed, they were often assigned to the least important patrol areas, however S-class submarines accounted for sinking 14 Japanese ships. Relegated to that of a training vessel in the latter stages of the war, twenty two of fifty one S Class submarines served their country valiantly and with heroic distinction against a tenacious enemy and tremendous odds.

Specifications listed below describe the four versions of the S-Class submarines deployed against Japan during World War II: S-1, S-11, S-42 and S-48.
