In the early 1950-s, to replace obsolete and disabled R-class submarines, the Peruvian Navy ordered a series of submarines in the United States that received the project «Sierra». Two submarines were commissioned in 1954, and two more in 1957. Although the S-class submarines did not have the opportunity to participate in full-fledged combat operations, they had a significant impact on strengthening the combat capabilities of the Peruvian navy.
