USS R-13

The USS R-13 (SS-90) was a R-class submarine of the United States Navy. She was commissioned in 1919 and served primarily in training and development roles throughout her career. As part of the first class of submarines designed and built after World War I, the R-13 was part of an experimental group that tested new technologies and tactics for undersea warfare.

Her service was largely centered around the Atlantic coast and involved participating in fleet exercises, conducting patrols, and contributing to the advancement of submarine design and operational capabilities. She was decommissioned in 1945 following the end of World War II and subsequently scrapped. While she did not engage in active combat during wartime, the USS R-13 played a valuable role in the interwar period, helping to refine the United States Navy's submarine capabilities. Her legacy lies in the contributions she made to the evolution of submarine technology and operational doctrine that would prove crucial in later conflicts.
