Editing Japanese aircraft carrier Hiryū (section)

===Armament===
''Hiryū''{{'}}s primary [[anti-aircraft gun|anti-aircraft]] (AA) armament consisted of six twin-gun mounts equipped with [[12.7 cm/40 Type 89 naval gun|12.7-centimeter Type 89]] [[dual-purpose gun]]s mounted on projecting [[sponson]]s, three on either side of the carrier's hull.<ref name=Brown19/> When firing at surface targets, the guns had a range of {{convert|14700|m|yd|sp=us}}; they had a maximum ceiling of {{convert|9440|m|ft|sp=us}} at their maximum elevation of +90 degrees. Their maximum rate of fire was 14 rounds a minute, but their sustained rate of fire was approximately eight rounds per minute.<ref>Campbell, pp. 192–193</ref> The ship was equipped with two Type 94 [[Fire-control system#Naval fire control|fire-control directors]] to control the {{convert|12.7|cm|in|adj=on|sp=us}} guns, one for each side of the ship;<ref name=pt3>Parshall & Tully, p. 143</ref> the starboard-side director was on top of the island and the other director was positioned below flight deck level on the port side.<ref name=Brown20>Brown 1977, p. 20</ref>

The ship's light AA armament consisted of seven triple and five twin-gun mounts for [[license-built]] [[25 mm Hotchkiss anti-aircraft gun|Hotchkiss]] [[Type 96 25 mm AT/AA Gun|25&nbsp;mm Type 96]] AA guns. Two of the triple mounts were sited on a platform just below the forward end of the flight deck.<ref>Brown 1977, p. 21</ref> The gun was the standard Japanese light AA gun during World War II, but it suffered from severe design shortcomings that rendered it largely ineffective. According to historian Mark Stille, the weapon had many faults including an inability to "handle high-speed targets because it could not be trained or elevated fast enough by either hand or power, its sights were inadequate for high-speed targets, it possessed excessive vibration and muzzle blast, and its magazines were too small to maintain high rates of fire".<ref>Stille 2007, p. 51</ref> These {{convert|25|mm|in|adj=on|sp=us|0}} guns had an effective range of {{convert|1500|-|3000|m|yd|sp=us}}, and an effective ceiling of {{convert|5500|m|ft|sp=us}} at an elevation of +85 degrees. The maximum effective rate of fire was only between 110 and 120 rounds per minute because of the frequent need to change the fifteen-round [[magazine (firearms)|magazines]].<ref>Campbell, p. 200</ref> The Type 96 guns were controlled by five Type 95 directors, two on each side and one in the bow.<ref name=pt3/>
