Crisis in November 1956, including a brief four-shot bombardment of Port Said. Reduced to reserve in August 1957, she was used as a barracks ship until 1961. She remained, unused, in the French Navy's inventory until 1970 when she was struck from the naval register and sold for scrap. Design When in 1934 Italy announced that it would begin building two s armed with guns, the French Navy immediately began preparations to counter them. The small s that had been ordered provided the template for the next French battleship design, but it needed to be scaled up to match the new Italian vessels, both in terms of offensive and defensive characteristics. The design staff considered 380 and guns, but the latter could not be incorporated in a design that remained within the limit imposed by the Washington Naval Treaty and was quickly discarded. The Dunkerques carried their armament in two quadruple gun turrets arrayed in a superfiring pair forward of the superstructure, and the designers experimented with other arrangements, including combinations of triple and twin turrets, but the need to minimize the length of the armor belt (and thus its weight) necessitated a repetition of the Dunkerque layout. Jean Bart displaced standard and fully loaded, with an overall length of , a beam of and a maximum draft of . She was powered by four Parsons geared steam turbines and six oil-fired Sural water-tube boilers, which developed a total of and yielded a maximum speed of . At a cruising speed of , the ship could steam for . Her crew numbered 1,569 officers and men. The ship carried four Loire 130 seaplanes on the fantail, and the aircraft facilities consisted of a steam catapult and a crane to handle the floatplanes. She was armed with eight 380 mm/45 Modèle (Mle) 1935 guns arranged in two quadruple gun turrets, both of which were placed in a superfiring pair forward of the superstructure. Her secondary armament consisted of nine /55 Mle 1930 guns mounted in three triple turrets, arranged on the rear superstructure. Heavy anti-aircraft (AA) defense consisted of twelve /45 Mle 1930 anti-aircraft guns in twin turrets. Close range anti-aircraft defense was provided by a battery of eight guns in twin mounts and twenty machine guns in four quadruple and two twin mounts. The ship's belt armor was thick amidships, and the main battery turrets were protected by of armor
