ww2dbaseShokaku was built at Yokosuka Dockyard, Japan. Completed in Aug 1941, she participated in Japan's early wartime offensives, including the attack on Pearl Harbor, the raid into the Indian Ocean and the Battle of Coral Sea. In the latter action, on 8 May 1942, Shokaku was seriously damaged by dive bombers from USS Yorktown (CV-5), but her modern designed allowed her to limp back to Japan for repairs and fight another day. However, that also meant she was to miss Midway action, where her presence might have tipped the balance of battle in Japan's favor. In Aug 1942, Shokaku took part in the Battle of the Eastern Solomons, where she helped in damaging but failed to sink the American carrier Enterprise. In Oct, she participated in the Battle of the Santa Cruz Islands in which she took on battle damage but her aircraft was able to sink the carrier Hornet. In 1943, Captain Hiroshi Matsubara took command of Shokaku. On 15 Jun 1944, she participated in Operation A-Go which led to the Battle of the Philippine Sea of 19 Jun. While refueling, she was hit at 1123 by three or four torpedoes from submarine Cavalla. The ensuing fire exploded a bomb at 1408, which ignited aviation fuel. As the fire grew out of control, she sank, taking 1,272 men to the bottom of the ocean with her. Only 570 men, including Captain Matsubara, survived.

19 Jun 1944	At dawn, Shokaku launched 17 A6M fighters for combat air patrol duties. At 1100 hours, she recovered 10 fighters; while still recovering fighters, at 1122, she was hit by three torpedoes from USS Cavalla on the starboard side; two forward near the switchboard and generator room, one aft of amidships. Large fuel fires were ignited in the hangar and No. 1 boiler room went offline. Shokaku remained underway, but began to list to starboard. Counterflooding over-compensated, giving her a port list. Meanwhile flooding and heat of the fires forced shutting down of the boiler rooms. She continued to settle forward. Though damage control initially hoped to save her, the flooding forward and the fires intensify in the following hours. By 1210 hours she had come to a halt when fires detonate an aerial bomb on the hangar, setting off volatile gases from a cracked forward tank. Large induced explosions wrecked the carrier, and hope began to fade. The list to port and bow trim both increased. At 1350 hours, her strike planes returned, but were ordered away, having to be directed to Zuikaku and Taiho. At this time Captain Matsubara had ordered abandon ship and the crew mustered on the flight deck for flag lowering. However, before the evacuation can proceed far, the bow dipped under and water pours into No. 1 elevator well, causing the carrier to corkscew to port and up-end. She went down by the bow at 1401 hours, stern raised high. Between 1408 and 1411, four underwater explosions were registered. 58 officers, 830 petty officers and men, 376 members of Air Group 601, and 8 civilians were killed, totalling 1,272 deaths. Light cruiser Yahagi and destroyers Urakaze and Hatsuzuki rescued Captain Hiroshi Matsubara among 570 other survivors.
31 Aug 1945	Shokaku was removed from the Japanese Navy List.
