Concord was initially built with the capacity to carry 224 mines, but these were removed early in her career to make way for more crew accommodations.

The lower torpedo tube mounts proved to be very wet and were removed, and the openings plated over, before the start of World War II.

[7] On her maiden cruise, from 23 November 1923 – 9 April 1924, Concord called at Mediterranean ports, passed through the Suez Canal to round the Cape of Good Hope, and exercised with the fleet in the Caribbean before returning to Philadelphia.

As flagship of Commander, Destroyer Squadrons, Scouting Fleet, she cruised the Caribbean and sailed through the Panama Canal to exercise in the Hawaiian Islands in 1924–1925.

[4] Serving as flagship of Commander, Cruiser Division 3 (CruDiv 3), Battle Force, Concord cruised the Pacific from her base at San Diego after early 1932, exercising in the Canal Zone and the Caribbean in 1934.

[4] From 5 September – 24 November 1943, with Captain Irving Reynolds Chambers, commanding, she carried Rear Admiral Richard E. Byrd on a tour to survey the potential use of a number of southeast Pacific islands in national defense and commercial aviation.

During this cruise, she suffered a gasoline explosion which killed 24 men including her executive officer,[9] and caused considerable damage, which was repaired at Balboa, Panama.

[4] With repairs completed in March 1944, Concord set sail northward to join the Northern Pacific Force at Adak on 2 April.

Serving as the flagship of Task Force 94 (TF 94) at the beginning of this duty, she joined in bombardments of the Kuriles which continued at intervals until the close of the war, preventing effective use by the Japanese of their bases there.

[4] On 31 August 1945, Concord stood out from Adak, covered the occupation landings at Ominato, Japan, from 8–14 September, and sailed on to Pearl Harbor, the Canal Zone, Boston, and Philadelphia, where she was decommissioned on 12 December, and sold for scrap on 21 January 1947.
