Attached to Submarine Division 1, R-21 operated out of the submarine base at New London, Conn. She conducted diving and approach tactical training in Long Island Sound, and conducted several training cruises in the vicinity of Block Island with other units of the division. Following a recruiting cruise to New Haven and Bridgeport 20-27 August, she returned to New London for upkeep.

R-21 continued practice dives off the coast into the fall with a eall at the Torpedo Station, Newport, R.I., 21 October. She departed New London 1 November 1919 in eomnany with R-22, R-24, R-27, and Eagle No. Sl. Proceeding via Hampton Roads, Wilmington, N.C., Savannah, Key West, Havana Cienfuegos, and Guarltarlamo Bay, Cuba; and Kingston, Jamaica, she arrived at Coco Solo, C.Z., 11 December.

Following several practice dives out of Coeo Solo, she transited the Panama Canal 27 January 1920 for dryDock work at Balboa, C.Z. Returning to Coco Solo, R-21 continued to refine her diving, approach, and torpedo tseties through the spring and summer. During two trips to Almirante Bay, 30 March-2 April and 17-20 May, she practiced with other units of the first division.

Designated SS-98 in July, R-21 again transited the eanal to Balboa 27 Sentember for a month in dryDock. UDon returning to Coco Solo, she was laid up for 11 months of extensive overhaul. She sailed north on 26 September 1921 via Guantanamo Bay, Key West, and New York, arriving New London on 27 October. She sailed to Portsmouth, N.H. 27 December for refitting.

A sueeessful test dive on 26 May 1922 meant that R-21 could return to New London. Through the spring and summer months she operated out of New London and Newport.

The craft of Submarine Division 1 sailed from New London 2 October 1922 for Coco Solo. R-21 served as flagship as the boats cruised via Hampton Roads and Guantanamo. After 11 days out, R-24 developed engine trouble and was temporarily taken under tow by R-21. The Cuba-bound steamer SS Bethore rendered assistance, and R-21 arrived at Coco Solo 27 October.

R-21 spent the rest of her active Navy days operating out of Coeo Solo and undergoing repairs at Balboa. She sailed from Coco Solo for the last time 15 February 1923 in company with a tender, Quail, and eight other submarines. Two days later R-21's engines malfunctioned and she was towed into Guantanamo by the tender. Repairs were quickly aceomplished and R-21 sailed for Philadelphia on the 22d, arriving there via Charleston 9 November 1923.
