radar and fire control equipment that would be later installed. Work on the hull was completed on 26 November 1947, which allowed her to be moved from the dry dock to the fitting-out quay. There, further modifications were made to the superstructure and the guns for her primary and secondary turrets were installed. Thereafter followed another stint in the dry dock from 20 March to 9 October 1948, which involved the installation of bulges to the lower hull and her propeller shafts were repaired. Initial testing of her propulsion machinery began on 4 December, followed by full tests that began in January 1949. She then conducted gunnery tests, and in May, she was assigned to the Groupe des bâtiments de ligne (Battleship Group) with Richelieu, though the unit was disbanded in 1950. Post war active service Jean Bart participated in training exercises with the fleet off the coast of North Africa in May and June 1950. She spent the next several months in Brest, and in early 1951 resumed initial training. She went to Le Havre in May to have a degaussing system installed, followed by further training cruises and tests to determine fuel consumption in June. By 7 July, she had returned to the fitting-out quay in Brest for additional work. The ship's main and secondary batteries were by now operational, and her propulsion system was complete, though she still lacked her anti-aircraft battery and fire control equipment. Beginning in November the shipyard embarked on the next phase modernization program, which included the installation of the anti-aircraft guns, modifying the 152 mm turrets to convert them to dual-purpose guns, and the fitting of fire control equipment. The new anti-aircraft battery consisted of twelve 100 mm guns in twin mounts and twenty-eight guns. At the same time, her main battery turrets were deactivated for preservation while work continued on the ship. Work on the ship's anti-aircraft battery proceeded very slowly. The 100 mm guns were installed by mid-1952, but the directors for the 100 mm guns were not installed until May 1953, permitting test firings of the guns in July. The tests revealed the need for extensive modifications to the systems that were finally complete in October 1954. The 57 mm guns were even more delayed, with the guns not ready for tests until September 1955, though their optical directors were not fitted until August 1956. The period of work
