USS R-2 (SS-79) was an R-class coastal and harbor defense submarine of the United States Navy. Her keel was laid down on 16 October 1917 by the Fore River Shipbuilding Company in Quincy, Massachusetts. She was launched on 23 September 1918 sponsored by Mrs. Charles M. Cooke, and commissioned at Boston, Massachusetts, on 24 January 1919 with Lieutenant Commander Charles Maynard "Savvy" Cooke, Jr., in command.

After acceptance trials in Cape Cod Bay, R-2 was assigned to Submarine Division 9 of the Atlantic Fleet and based at New London, Connecticut. She sailed on 4 December 1919 for Norfolk, Virginia, and winter division maneuvers in the Gulf of Mexico. Returning to New London on 28 May, she joined R-1 and R-3 for four months of summer exercises off southern New England. Given hull classification symbol SS-79 in July, R-2 headed for Norfolk on 13 September 1920 for an overhaul.

R-2 was transferred to the Pacific fleet on 14 April 1921, transited the Panama Canal on 28 May, and arrived on 30 June at her new base, San Pedro, California. She took part in fleet exercises off Central America from 5 February to 6 April 1923. Returning to San Pedro on 10 April, R-2 was ordered to Hawaii on 16 July with Division 9 and remained for eight years developing submarine tactics with the Fleet. She made an endurance cruise to Midway Island in July and August 1924.
