Following trials, R-2 was assigned to New London, joining SubDiv 9. She was transferred to the Pacific in 1921. In 1923 she joined SubDiv 9, Pacific Fleet, in Hawaii, where she remained for 8 years.

In June 1941, R-2 was transferred to Key West, where she would remain for the rest of her service. Attached to the Fleet Sonar School, she would also make a few defensive patrols. In May 1945, she was sent to Philadelphia, where she was decommissioned on 10 May 1945, and stricken on 2 June. She was scrapped in early 1946.
