As designed, the light anti-aircraft battery was to have consisted of automatic guns in twin Mle 1935 mounts, but these were not ready by 1939, and so the two amidships 152 mm turrets were replaced with a group of twelve /45 Mle 1930 anti-aircraft guns in twin turrets. These were dual-purpose guns, but were outfitted primarily with time-fused shells for anti-aircraft defense, as the 152 mm guns were expected to fulfill the close-range anti-ship role. Since the automatic 37 mm guns were not available, eight 37 mm Mle 1925 semi-automatic guns in four twin mounts were added. These light guns were complemented with a battery of twenty-four Hotchkiss M1929 machine gun machine guns in six quadruple mounts.
