The most significant change to the design for "Clemenceau" was to the arrangement of the secondary and anti-aircraft batteries. The number of triple 152 mm turrets was reduced to four, with two amidships wing turrets and two turrets on the centerline aft of the superstructure. Though the number of guns was reduced, the new arrangement actually secured the same broadside, as three turrets could still be brought to bear to either side of the ship. In an effort to keep displacement from growing too much, the belt armor was reduced to . The hangar would have to be shortened to accommodate the centerline arrangement of the 152 mm guns, but the hangar would also be widened to allow two aircraft to be stored side by side, thus preserving the same complement as "Richelieu".
