94 and Type 95 AA directors were added to control the additional guns. The ammunition for these new guns was stored in the magazines originally used for the 14 cm guns and for Turret No. 5. During 1944, the ships' AA defences were reinforced with an additional dozen triple and eleven single 25 mm gun mounts, for a total of 104 barrels, and a pair of Type 13 early warning radars were added. In September six 30-round AA rocket launchers were added on the sides of the flight deck. Flight deck arrangements A flight deck was built above the stern and stretched forward to the rebuilt aft superstructure. The flight deck was wide at its forward end and at the stern. It overhung the stern and increased the overall length of the ships to . A pair of rotating gunpowder-propelled catapults were fitted on the sides of the hull, forward of the aft superstructure where they partially restricted the arc of fire of the two amidships turrets. They could launch aircraft up to in weight and required 30 seconds to launch each aircraft. The flight deck had eight permanent storage positions connected by rails to the catapults and the hydraulically operated aircraft lift that brought the aircraft up from the hangar below on the trolleys used to move the floatplanes about. Two aircraft were intended to be stowed on the catapults and three more in temporary positions on the flight deck for a total of thirteen. The hangar was wide forward and at the rear. It was high and designed to stow nine aircraft. It was fitted with fire fighting foam and carbon dioxide dispensers as a result of wartime experience. The 'T'-shaped lift was wide at its forward end and wide at its aft end. It was also 12.1 metres long and had a capacity of . Petrol storage tanks with a capacity of were installed in the former magazine of Turret No. 6 to provide each aircraft with enough fuel for three sorties. To recover the aircraft the collapsible crane formerly on the stern was moved up to the port side of the flight deck. Another crane was intended on the starboard side, but it was never fitted. The ships had an air group of 11 each of Yokosuka D4Y dive bombers (Allied reporting name "Judy") and Aichi E16A reconnaissance aircraft (Allied reporting name "Paul"). Both aircraft had
