At Guantanamo Bay in February, she operated in formation in and around the Virgin Islands in March, before returning to Coco Solo. In May, O14 with O15 and O16 resumed diving operations, which continued into 1923 as SubDiv 10 conducted diving tactical operations. In November, O14 proceeded to Philadelphia.
Decommissioning 17 June 1924, O14 was turned over to the Commandant, Navy Yard, Philadelphia. Struck from the Navy Register 9 May 1930, the boat was scrapped in accordance with the London Naval Treaty 30 July 1930.
