After entering service, "Dunkerque" continued her training program, though she was now included in exercises with the rest of the squadron. At the time, the squadron included the three s (the 2nd Battle Division), three cruisers (the 4th Cruiser Division), the aircraft carrier , and numerous destroyers and torpedo boats. From 18 to 20 October, she took part in maneuvers with "Béarn", two torpedo boats, and a sloop off the coast of Brittany. "Dunkerque" departed Brest on 8 November in company with "Béarn" and the 4th Cruiser Division for a visit to Cherbourg to celebrate the twentieth anniversary of the Armistice with Germany that ended World War I. The ships thereafter got underway for training exercises that concluded with a return to Brest on 17 November. "Dunkerque" then used the wreck of the old battleship as a target before returning to the shipyard for maintenance that lasted until 27 February 1939.
