caption_attribution_description: English: USS Yorktown (CV-5) is hit on the port side, amidships, by a Japanese Type 91 aerial torpedo during the mid-afternoon attack by planes from the carrier Hiryu, in the Battle of Midway, on 4 June, 1942. Yorktown is heeling to port and is seen at a different aspect than in other views taken by USS Pensacola (CA-24), indicating that this is the second of the two torpedo hits she received. Note very heavy anti-aircraft fire.
context_page_description: Hiryū was an aircraft carrier built for the Imperial Japanese Navy during the 1930s. Generally regarded as the only ship of her class, she was built to a modified 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's 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 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 USS 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.
context_section_description: Concerned by the US carrier strikes in the Marshall Islands, Lae-Salamaua, and the Doolittle raids, Yamamoto was determined to force the US 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 codenamed the Midway invasion Operation MI. Unknown to the Japanese, the US 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 3 A6Ms of the 6th Kōkūtai intended as the aerial garrison for Midway. With the fleet positioned 250 nmi (460 km; 290 mi) northwest of Midway at dawn (04:45 local time) on 4 June 1942, Hiryū's 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 AA 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 US 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 3 Zeros to the total of 11 assigned to the initial CAP over the four carriers. By 07:05, the carrier had 6 fighters with the CAP which helped to defend the Kido Butai from the first US attackers from Midway Island at 07:10. At this time, Nagumo's carriers were attacked by 6 US Navy Grumman TBF Avengers and 4 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 6 from Hiryū, immediately attacked the American airplanes, shooting down 5 of the Avengers and 2 of the B-26s. The Avengers shot down 1 of Hiryū's 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 itself. 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 Hiryū's 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. Hiryū's 3 CAP fighters were among the 9 still aloft that attacked Henderson's planes, shooting down 6 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 Hiryū's Zeros. At roughly the same time, the Japanese carriers were attacked by 12 USAAC B-17s, bombing from 20,000 feet (6,100 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 3 more Zeros at 08:25. These fresh Zeros help
