ww2dbaseHiryu was completed at Yokosuka, Japan in 1939. She was a member of Chuichi Nagumo's dreaded Mobile Force, and was one of the fleet carriers that launched the deadly attack on Pearl Harbor in Dec 1941. She participated in the Battle of Midway and launched the aircraft that disabled the American carrier Yorktown. Hiryu then came under attack by Yorktown's SBD aircraft, which fought through Hiryu's combat air patrol fighters and a flak barrage. Captain Susumu Kawaguchi, air officer aboard Hiryu, recalled that Hiryu was hit six times during the fourth and final attack on her. One of the bombs struck the forward elevator, two just aft of the forward elevator, three just forward of the after elevator. All bombs were aimed at her hinomaru painted on her flight deck, a proud symbol of the rising sun that ironically doubled as the bull's-eye to the American pilots.

ww2dbaseWhen he determined that Hiryu was unsaveable, her captain Tamon Yamaguchi gathered the 800 men who were still aboard the ship, including the wounded, on the flight deck near the bridge, and led them in yelling banzai three times toward Tokyo, followed by the playing of the national anthem. After the ceremony, the order to abandon ship was issued. It was recorded that Yamaguchi and Tomeo Kaku (Hiryu's captain) had this exchange as they shared naval biscuits and water while the ship being abandoned, the exchange signifying how much the two officers had in common.

ww2dbase"Let us enjoy the beauty of the moon", Yamaguchi said to Kaku.

ww2dbase"How bright it shines," Kaku responds.

ww2dbase"It must be in its 21st day."

ww2dbaseAdmiral Kusaka was aboard the Hiryu that day, and recalled Hiryu's commanders Rear Admiral Tamon Yamaguchi and Captain Tomeo Kaku.

When it was ascertained that the ship was in a sinking condition, Admiral Yamaguchi and Captain Kaku decided that they would go down with the ship. They all shared some naval biscuits and rank a glass of water in a last ceremony. Admiral Yamaguchi gave his hat to one of his staff officers and asked him to give it to his family; then there was some joking among them, the captain and the admiral, that their duties were finished when the ship sank.

ww2dbaseAfter the survivors were evacuated (without Yamaguchi, who remained on board to go down with the ship), destroyer Makigumo fired two torpedoes to scuttle her some time between 0905 and 0915 in the morning of 5 Jun 1942. The first torpedo passed under her, but the second hit her squarely in the hull.

ww2dbaseEnsign Mandai, who floated in the water nearby when Hiryu sank, saw the giant propellers rose above the waves as the bow of the ship dipped into the ocean. He swam vigorously to escape the suction created when a ship sank; when he dared to look again, Hiryu was gone.

Soryu and Hiryu were truly first class carriers, probably the best in the world in their day. Pity the dangfool IJN wasted them at Midway...

The Americans always considered Soryu and Hiryu as being small carriers; actually, they were comparable in size to the USN Yorktown Class and were faster by about three knots (35Kn/hr) due to more powerful propulsion plants. Hiryu 153,000 HP; Yorktown 120,000 HP. Hiryu HP only exceeded by the two Shokakus (Shokaku, Zuikaku) that had 160,000 HP and were probably the best IJN carriers overall.

Lexington & Yorktown were (888 ft) 140 feet longer than Hiryu, and carried 78 vs 64 aircraft.
