She was launched on 17 June 1920 sponsored by Mrs. James E. Palmer, and commissioned on 21 February 1921 with Lieutenant Commander Thomas Shine in command.

Following duty off the northeast coast, S-9 sailed from New London, Connecticut, on 31 May 1921, and proceeded via the Panama Canal, California, and Pearl Harbor to the Philippines, arriving at Cavite, Luzon on 6 December. There, she joined Submarine Division 12 (SubDiv 12), whose S-boats — along with those of SubDiv 18 — had arrived on 1 December. In 1922, she sailed from Cavite on 11 October visited Hong Kong from 14–28 October, and returned to Cavite on 31 October. On 30 April 1923, she departed from Cavite and visited Shanghai, Chefoo, and Chinwangtao, China, before returning via Woosung and Amoy to Cavite on 11 September. On 23 June 1924, she sailed from Manila Bay and again visited ports in China before returning to Olongapo on 23 September.

Departing from Cavite on 29 October, S-9 arrived at Mare Island, California on 30 December. Remaining at Mare Island in 1925, she operated along the West Coast in 1926, mainly at San Francisco, San Pedro, and San Diego, California. Departing Mare Island on 11 February 1927, she operated in the Panama Canal area from March into April, arrived at New London on 3 May, and spent the remainder of 1927 along the northeast coast.
