Aircraft carrier of the Imperial Japanese Navy

Hiryū (飛龍) was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the 1930s. Generally regarded as the only ship of her class, she was built to a modified Japanese aircraft carrier Sōryū design. Her aircraft supported the Japanese invasion of French Indochina in mid 1940. She took part in the attack on Pearl Harbor and the Battle of Wake Island. During the first few months of the Pacific War, the ship supported the conquest of the Dutch East Indies in January 1942. The following month, her aircraft bombed Darwin, Australia; and continued to assist in the Dutch East Indies campaign. In April, Hiryū aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean Raid. After a brief refit, Hiryū and three other fleet carriers of the First Air Fleet (Kido Butai) participated in the Battle of Midway in June 1942. After bombarding American forces on the atoll, the carriers were attacked by aircraft from Midway and the carriers Enterprise, Hornet, and Yorktown. Dive bombers from Yorktown and Enterprise crippled Hiryū and set her afire. She was scuttled the following day after it became clear that she could not be salvaged. The loss of Hiryū and three other IJN carriers at Midway was a crucial strategic defeat for Japan and contributed significantly to the Allies' ultimate victory in the Pacific.

Hiryū was one of two large carriers approved for construction under the 1931 – 1932 Supplementary Program. Originally designed as the sister ship of Sōryū, her design was enlarged and modified in light of the Tomozuru and Fourth Fleet Incidents in 1934 –1935 that revealed many IJN ships were top heavy, unstable and structurally weak. Her forecastle was raised and her hull strengthened. Other changes involved increasing her beam, displacement, and armor protection. The ship had a length of overall, a beam of and a draft of She displaced at standard load and at normal load. Her crew consisted of 1,100 officers and enlisted men.

Hiryū was fitted with four geared steam turbine sets with a total of , each driving one propeller shaft using steam provided by eight Kampon water tube boilers. and made her the fastest carrier in the world at the time of her commissioning. Hiryū carried of fuel oil which gave her a range of at The boiler uptakes were trunked to the ship's starboard side amidships and exhausted just below flight deck level through two funnels curved downward.

The carrier's flight deck was 88 feet (27 m) wide and overhung her superstructure at both ends, supported by pairs of pillars. The upper hangar was and had an approximate height of 15 feet (5 m); the lower was and had an approximate height of 14 feet (4 m). Together they had an approximate total area of
Aircraft were transported between the hangars and the flight deck by three elevators, the forward one abreast the island on the centerline and the other two offset to starboard. The ship was equipped with two Type 94 fire control directors to control the guns, one for each side of the ship; the starboard side director was on top of the island and the other director was positioned below flight deck level on the port side. The ship's light AA armament consisted of seven triple and five twin gun mounts for license built Hotchkiss 25 mm Type 96 AA guns. Two of the triple mounts were sited on a platform just below the forward end of the flight deck. 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". These guns had an effective range of , and an effective ceiling of 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 magazines. The Type 96 guns were controlled by five Type 95 directors, two on each side and one in the bow. The ship was laid down at the Yokosuka Naval Arsenal on 8 July 1936, launched on 16 November 1937 and commissioned on 5 July 1939. She was assigned to the Second Carrier Division on 15 November. In September 1940, the ship's air group was transferred to Hainan Island to support the Japanese invasion of French Indochina. In February 1941, Hiryū supported the blockade of Southern China. Two months later, the 2nd Carrier Division, commanded by Rear Admiral Tamon Yamaguchi, was assigned to the First Air Fleet, or Kido Butai, on 10 April. Hiryū returned to Japan on 7 August and began a short refit that was completed on 15 September. She became flagship of the Second Division from 22 September to 26 October while Sōryū was refitting. Now the flagship of the Second Carrier Division, the ship embarked 21 Mitsubishi A6M Zero fighters, 18 Aichi D3A "Val" dive bombers, and 18 Nakajima B5N "Kate" torpedo bombers. From a position north of Oahu, Hiryū and the other five carriers launched two waves of aircraft on the morning of 7 December 1941 Hawaiian time. In the first wave, 8 B5N torpedo bombers were supposed to attack the aircraft carriers that normally berthed on the northwest side of Ford Island, but none were in Pearl Harbor that day; 4 of the B5N pilots diverted to their secondary target, ships berthed alongside "1010 Pier" where the fleet flagship was usually moored. That ship, the battleship Pennsylvania, was in drydock and its position was occupied by the light cruiser Helena and the minelayer Oglala; all four torpedoes missed. The other four pilots attacked the battleships West Virginia and Oklahoma. The remaining 10 B5Ns were tasked to drop armor piercing bombs on the battleships berthed on the southeast side of Ford Island ("Battleship Row") and may have scored one or two hits on them, in addition to causing a magazine explosion aboard the battleship Arizona that sank her with heavy loss of life. The 6 A6M Zeros strafed parked aircraft at Marine Corps Air Station Ewa (MCAS Ewa), claiming 22 aircraft destroyed. on the ground for the loss of one of their own. The D3As attacked various ships in Pearl Harbor, but it is not possible to identify which aircraft attacked which ship. Two D3As from Hiryū were lost during the attack, one shot down by Second Lieutenant George Welch. While returning to Japan after the attack, Vice Admiral Chūichi Nagumo, commander of the First Air Fleet, ordered that Sōryū and Hiryū be detached on 16 December to attack the defenders of Wake Island who had already defeated the first Japanese attack on the island. before they were shot down by PO3c Isao Towara. Hiryū and Sōryū arrived at Palau on 28 January and waited for the arrival of the carriers Japanese aircraft carrier Kaga and Akagi. All four carriers departed Palau on 15 February and launched air strikes against Darwin, Australia, four days later. Hiryū contributed 18 B5Ns, 18 D3As, and 9 Zeros to the attack. Her aircraft attacked the ships in port and its facilities, sinking or setting on fire three ships and damaging two others. The Zeros destroyed 1 P 40E as it was taking off, 2 Consolidated PBY Catalina seaplanes on the water, and a Zero was forced to crash land after being damaged by a P 40E of the United States Army Air Forces (USAAF) 33rd Pursuit Squadron. Hiryū and the other carriers arrived at Staring Bay on Celebes Island on 21 February to resupply and rest before departing four days later to support the invasion of Java. Two days later, they attacked Christmas Island and Hiryūs aircraft sank the Dutch freighter Poelau Bras before returning to Staring Bay on 11 March

On 26 March, the five carriers of the First Air Fleet departed from Staring Bay; they were spotted by a Catalina about southeast of Ceylon on the morning of 4 April. Six of Hiryūs Zeros were on Combat Air Patrol (CAP) and helped to shoot it down. Nagumo closed to within of Colombo before launching an airstrike the next morning. Hiryū contributed 18 B5Ns and 9 Zeros to the force; the latter encountered a flight of 6 Fairey Swordfish torpedo bombers from 788 Naval Air Squadron en route and shot them all down without loss. The Japanese aircraft encountered defending Hawker Hurricane fighters from Nos. 30 and 258 Squadrons RAF over Ratmalana airfield and Hiryūs fighters claimed to have shot down 11 with 3 Zeros damaged, although the fighters from the other carriers also made claims. British losses were 21 Hurricanes shot down and 2 more forced to crash land. The D3As and B5Ns inflicted some damage to the port facilities, but a day's warning had allowed much of the shipping in the harbor to be evacuated. The British were attempting to find Nagumo's ships all morning and Hiryūs Zeros on CAP over the fleet helped to shoot down an RAF Catalina, shot down a Fairey Albacore torpedo bomber and drove off another from the carrier Later that morning the British heavy cruisers and were spotted and Hiryū launched 18 D3As. They sank both ships in combination with the dive bombers from the other carriers. On the morning of 9 April, Hiryūs CAP shot down another Catalina attempting to locate the fleet and, later that morning, contributed 18 B5Ns, escorted by 6 Zeros, to the attack on Trincomalee. The fighters engaged 261 Squadron RAF, claiming to have shot down two with two more shared with fighters from the other carriers. British losses were only eight fighters, but the Japanese pilots claimed a total of 49 aircraft shot down when the RAF only had 16 Hurricanes in the fight. The British pilots shot down one of Hiryūs B5Ns and forced another to crash land while they were bombing the port. Meanwhile, a floatplane from the battleship Japanese battleship Haruna spotted the small aircraft carrier , escorted by the destroyer , and every available D3A was launched to attack the ships, escorted by nine Zeros. Hiryū contributed 18 dive bombers and 3 fighters, but they arrived too late to assist in sinking them and found two other ships further north. They sank the freighter RFA Athelstone and her escorting corvette, While this was going on, Akagi narrowly escaped damage when 9 British Bristol Blenheim bombers from Ceylon penetrated the CAP and dropped their bombs from 11000 feet (3353 m). Hiryū had eight Zeros aloft, along with 12 more from the other carriers, and collectively they accounted for 5 of the British bombers for the loss of 1 of Hiryūs Zeros. The Blenheims ran into the D3As from Japanese aircraft carrier Shōkaku, escorted by Hiryūs Zeros, on their way back home and lost one more bomber to the Japanese aircraft. The dive bombers claimed to have shot down two Blenheims in conjunction with the Zeros, which claimed one on their own, for the loss of one Zero shot down by the bombers' gunners and one D3A damaged. After launching the dive bombers that sank Hermes and the other ships, the First Air Fleet reversed course and headed southeast for the Malacca Strait and Japan. On 19 April, while transiting the Bashi Straits between Taiwan and Luzon en route to Japan, Hiryū, Sōryū, and Akagi were sent in pursuit of the American carriers Hornet and Enterprise, which had launched the Doolittle Raid against Tokyo. They found only empty ocean, as the American carriers had immediately departed the area to return to Hawaii. The carriers quickly abandoned the chase and dropped anchor at Hashirajima anchorage on 22 April. Having been engaged in constant operations for four and a half months, the ship, along with the other three carriers of the First and Second Carrier Divisions, was hurriedly refitted and replenished in preparation for the Combined Fleet's next major operation, scheduled to begin one month hence. While at Hashirajima, Hiryūs air group was based ashore at Tomitaka Airfield, near Saiki, Ōita, and conducted flight and weapons training with the other First Air Fleet carrier units.

Concerned by the American carrier strikes in the Marshall Islands, Lae Salamaua, and the Doolittle raids, Yamamoto was determined to force the U. S. Navy into a showdown to eliminate the American carrier threat. He decided to invade and occupy Midway Atoll, which he was sure would draw out the American carriers to defend it. The Japanese code named the Midway invasion Operation MI. Unknown to the Japanese, the U. S. Navy had divined the Japanese plan by breaking its JN 25 code and had prepared an ambush using its three available carriers, positioned northeast of Midway. On 25 May 1942, Hiryū set out with the Combined Fleet's carrier striking force in the company of Kaga, Akagi, and Sōryū, which constituted the First and Second Carrier Divisions, for the attack on Midway. Her aircraft complement consisted of 18 Zeros, 18 D3As, and 18 B5Ns. Also aboard were three A6Ms of the 6th Kōkūtai intended as the aerial garrison for Midway. With the fleet positioned northwest of Midway at dawn (04:45 local time) on 4 June 1942, Hiryūs portion of the 108 plane airstrike was an attack on the facilities on Sand Island with 18 torpedo bombers, one of which aborted with mechanical problems, escorted by nine Zeros. The air group suffered heavily during the attack: Two B5Ns were shot down by fighters, with a third falling victim to antiaircraft fire. Heavy damage forced a fourth, flown by squadron leader Rokuro Kikuchi, to crash land on Kure Atoll, where he and his crew were later discovered and killed by U. S. forces. A fifth B5N was forced to ditch on its return, and five more were damaged beyond repair. In addition, two Zeros were also deemed unserviceable, although none were lost. The carrier also contributed three Zeros to the total of 11 assigned to the initial CAP over the four carriers. By 07:05, the carrier had six fighters with the CAP, which helped to defend the Kido Butai from the first U. S. attackers from Midway Island at 07:10. At this time, Nagumo's carriers were attacked by six U. S. Navy Grumman TBF Avengers and four USAAC Martin B 26 Marauders, all carrying torpedoes. The Avengers went after Hiryū while the Marauders attacked Akagi. The 30 CAP Zeros in the air at this time, including the six from Hiryū, immediately attacked the American airplanes, shooting down five of the Avengers and two of the B 26s. The Avengers shot down one of Hiryūs Zeros. The surviving aircraft dropped their torpedoes, but all missed. At 07:15, Nagumo ordered the B5Ns on Kaga and Akagi rearmed with bombs for another attack on Midway Island. This process was slowed by the number of ordnance carts used to handle the bombs and torpedoes and the limited number of ordnance elevators. This meant that the torpedoes could not be struck below until after all the bombs were moved up from their magazine, assembled and mounted on the aircraft. This process normally took about an hour and a half; more time would be required to bring the aircraft up to the flight deck, and to warm up and launch the strike group. Around 07:40, he reversed his order when he received a message from one of his scout aircraft that American warships had been spotted. Depleted of ammunition, two of Hiryūs CAP Zeros landed aboard the carrier at 07:40. At 07:55, the next American strike from Midway arrived in the form of 16 Marine Douglas SBD Dauntless dive bombers of Marine Scout Bomber Squadron 241 (VMSB 241) under Major Lofton R. Henderson. Hiryūs three CAP fighters were among the nine still aloft that attacked Henderson's planes, shooting down six of them as they executed a fruitless glide bombing attack on Hiryū. In return, the gunner of one of the Dauntlesses shot down one of Hiryūs Zeros. At roughly the same time, the Japanese carriers were attacked by 12 USAAC B 17s, bombing from 20000 feet (6096 m). The high altitude of the B 17s gave the Japanese captains enough time to anticipate where the bombs would land, and they successfully maneuvered out of the impact area. Four B 17s attacked Hiryū, but missed with all their bombs. Hiryū reinforced the CAP with launches of three more Zeros at 08:25. These fresh Zeros helped defeat the next American air strike from Midway, 11 Vought SB2U Vindicator dive bombers from VMSB 241, which attacked the battleship Haruna starting around 08:30. Haruna escaped damage and three of the Vindicators were shot down. Although all the American air strikes had thus far caused negligible damage, they kept the Japanese carrier forces off balance as Nagumo endeavored to prepare a response to news, received at 08:20, of the sighting of American carrier forces to his northeast. Hiryū began recovering her Midway strike force at around 09:00 and finished shortly by 09:10. The landed aircraft were quickly struck below, while the carriers' crews began preparations to spot aircraft for the strike against the American carrier forces. The preparations were interrupted at 09:18, when the first attacking American carrier aircraft were sighted. These consisted of 15 Douglas TBD Devastator torpedo bombers of VT 8, led by Lieutenant Commander John C. Waldron from the Hornet. They attempted a torpedo attack on Soryū, but all of the American planes were shot down by the 18 CAP fighters, leaving one surviving aviator treading water. Shortly afterwards, 14 Devastators from Torpedo Squadron 6 (VT 6) from Enterprise, led by Lieutenant Commander Eugene E. Lindsey, attacked. Lindsey's aircraft tried to sandwich Kaga, but the CAP, reinforced by four additional Zeros launched by Hiryū at 09:37, shot down all but four of the Devastators, and Kaga dodged the torpedoes. Hiryū launched another trio of CAP Zeros at 10:13 after Torpedo Squadron 3 (VT 3) from Yorktown was spotted. Two of her Zeros were shot down by Wildcats escorting VT 3 and another was forced to ditch. While VT 3 was still attacking Hiryū, American dive bombers arrived over the Japanese carriers almost undetected and began their dives. It was at this time, around 10:20, that in the words of Jonathan Parshall and Anthony Tully, the "Japanese air defenses would finally and catastrophically fail." Three American dive bomber squadrons now attacked the three other carriers and set each of them on fire. Hiryū was untouched and proceeded to launch 18 D3As, escorted by six Zeros, at 10:54. En route, the Zeros engaged a group of Enterprise SBDs that they had spotted. They failed to shoot down any of the dive bombers, but two of the Zeros were shot up by the bombers' rear gunners, with one Zero forced to ditch near a destroyer on its return. American radar detected the incoming Japanese dive bombers at 11:52 and vectored Yorktowns CAP of 20 Wildcats against them. The Wildcats shot down three of the remaining Zeros for the loss of one of their own and engaged the D3As. Only seven of the dive bombers survived long enough to make their attack on Yorktown and two of those were shot down by flak during their dive, but they made three direct hits and two near misses that badly damaged the carrier and set her on fire. Confident that his men had sunk Yorktown, Yamaguchi launched a second wave of ten B5Ns (including one from Akagi), escorted by six Zeros (two from Kaga), at 13:30, with the instruction that they attack a separate carrier than that hit by the first wave. However, the Americans had managed to extinguish the fires on Yorktown by 14:00, and the carrier was making by 14:30 when the second strike group approached. As a result, the strike pilots mistook her for one of her undamaged sisters, and launched the attack. At that moment, six Wildcats were on CAP duty, and four of these were vectored toward the attacking aircraft while the other two were retained to cover the takeoff of ten Wildcats fueling on deck. The Japanese were jumped at 14:38 by two Wildcats, which shot down one torpedo bomber before they were both shot down by the escorting Zeros (two Zeros were shot down later for the loss of one Wildcat). Four more B5Ns fell during the attack, but two of the survivors managed to score hits on Yorktown that damaged three boilers and knocked out all electrical power so that she could not pump fuel oil to starboard to counteract her six degree list to port. Seventeen minutes later, after the list increased to 23 degrees, the crew was ordered to abandon ship. Of the four Zeros and five B5Ns that returned to Hiryū, only two Zeros and three bombers were still airworthy. Yamaguchi radioed his intention to Nagumo at 16:30 to launch a third strike against the American carriers at dusk (approximately 18:00), but Nagumo ordered the fleet to withdraw to the west. Unbeknownst to the Japanese, Enterprise and Hornet had already launched airstrikes well before then. Enterprise launched a total of 26 Dauntlesses at 15:25 using her own aircraft plus those from Yorktown that had been forced to recover aboard her after Yorktown was damaged, and Hornet launched 16 more of her own Dauntlesses at 16:00. At this point in the battle, Hiryū had only four airworthy dive bombers and five torpedo planes left. She also retained 19 of her own fighters on board, as well as a further 13 Zeros on CAP (a composite force of survivors from the other carriers). At 16:45, Enterprises dive bombers spotted the Japanese carrier and began to maneuver for good attacking position while reducing altitude. At 16:56, just as the first Dauntlesses were beginning their dives, Nagumo ordered a change in course to 120 degrees, possibly to prepare to recover his reconnaissance floatplanes, that threw off the aim of the leading SBDs. The Japanese did not even spot the Americans until 17:01. The CAP shot down two of the American aircraft in their dives and another after it was forced to abort its dive when some of Yorktowns SBDs passed in front of it, starting their own dives. Hiryū was struck by four bombs, three on the forward flight deck and one on the forward elevator. The explosions started fires among the aircraft on the hangar deck. The forward half of the flight deck collapsed into the hangar while part of the elevator was hurled against the ship's bridge. The fires were severe enough that the remaining American aircraft attacked the other ships escorting Hiryū, albeit without effect, deeming further attacks on the carrier as a waste of time, because she was aflame from stem to stern. Beginning at 17:42, two groups of B 17s attempted to attack the Japanese ships without success, although one bomber strafed Hiryūs flight deck, killing several anti aircraft gunners. Although Hiryūs propulsion was not affected, the fires could not be brought under control. At 21:23, her engines stopped, and at 23:58 a major explosion rocked the ship. The order to abandon ship was given at 03:15, and the survivors were taken off by the destroyers Japanese destroyer Kazagumo and Japanese destroyer Makigumo. Yamaguchi and Kaku decided to remain on board as Hiryū was torpedoed at 05:10 by Makigumo as the ship could not be salvaged. One torpedo missed and the other struck near the bow without the typical plume of water, although the detonation was quite visible. Around 07:00, one of Japanese aircraft carrier Hōshō's Yokosuka B4Y aircraft discovered Hiryū still afloat and not in any visible danger of sinking. The aviators could also see crewmen aboard the carrier, men who had not received word to abandon ship. They finally launched some of the carrier's boats and abandoned ship around 09:00. Thirty nine men made it into the ship's cutter only moments before Hiryū sank around 09:12, taking the bodies of 389 men with her. The cutter drifted for 14 days before being discovered by a PBY Catalina and rescued by the seaplane tender Ballard. Four men died of their wounds or exposure before being picked up and a fifth died that night. The loss of Hiryū and the three other IJN carriers at Midway, comprising two thirds of Japan's total number of fleet carriers and the experienced core of the First Air Fleet, was a strategic defeat for Japan and contributed significantly to Japan's ultimate defeat in the war. In an effort to conceal the defeat, the ship was not immediately removed from the Navy's registry of ships, instead being listed as "unmanned" before finally being struck from the registry on 25 September 1942. The IJN selected a modified version of the Hiryū design for mass production to replace the carriers lost at Midway. Of a planned program of 16 ships of the Unryū class, only six were laid down and three were commissioned before the end of the war.
