ww2dbaseCommissioned with Captain Yokokawa Ichibei in command only three months before the Pearl Harbor attack, fleet carrier Zuikaku nevertheless participated in the attack that started the Pacific War. During the Pearl Harbor attack, the first wave of 30 aircraft launched from her flight deck attacked Wheeler Field and Naval Air Station at Kaneohe, while the second wave of 44 aircraft attacked Hickam Field and battleships California and Maryland. The attack was a stunning success, and the pilots returned as heroes.

ww2dbaseOn 20 Jan 1942, Zuikaku's aircraft attacked Rabaul. On 21 Jan, they attacked Lae, New Guinea. In Apr 1942, she was a member of the task force that ventured into the Indian Ocean and struck the British naval bases at Ceylon.

ww2dbaseIn May 1942, Zuikaku participated in Operation MO, which was the invasion plan of Port Moresby. The Japanese signals were intercepted and decrypted by Allied intelligence, and carriers Yorktown and Lexington were dispatched. The ensuing Battle of the Coral Sea cost her half of her aircraft, while her sister ship Shokaku was heavily damaged by three bombs. As a result, both carriers were unable to participate in the Battle of Midway in the following month, where the presence of these two additional fleet carriers could have resulted in a much different outcome.

ww2dbaseUnder the command of Captain Tameteru Notomo, Zuikaku sailed for the Solomon Islands in Aug 1942. During the Battle of the Eastern Solomons on 24 Aug 1942, Zuikaku and Shokaku's air groups heavily damaged Enterprise with three 1,000-lb bomb hits, but Enterprise's effective damage control kept the American carrier from becoming disabled. A second wave of dive bombers from Shokaku and Zuikaku failed to locate the damaged Enterprise, thus while Enterprise would end up being sidelined for repairs for three months, she survived to fight later in the war.

ww2dbaseIn Feb 1943, Zuikaku and her aircraft covered the evacuation of Guadalcanal. Later that year, Captain Kikuchi Tomozo took over command of the carrier and countered American naval forces in the Marshall Islands area.

ww2dbaseIn Jun 1944, Zuikaku participated in Operation A-Go which led to the Battle of Philippine Sea. At the end of the battle, 429 Japanese aircraft were destroyed, along with the destruction of Taiho and Shokaku by submarines. Zuikaku was now the last surviving carrier of the Pearl Harbor attack.

ww2dbaseIn Oct 1944, Zuikaku was Admiral Jisaburo Ozawa's flagship for the decoy fleet that successfully lured away Admiral William Halsey's fleet, therefore allowing the Battle off Samar to take place. On 25 Oct 1944, Halsey's overwhelmingly powerful force caught up with Ozawa's. The first American attack wave at 0830 hours scored three bomb hits and one torpedo hit, causing fires and heavy flooding, but Zuikaku's experienced damage control teams extinguished all fires and corrected the listing by 0850 hours. At 0953 hours, the second wave came, and within 15 minutes denied the Japanese from using any of their flight decks, thus any Japanese aircraft remaining in the air must ditch in the water when they would run out of fuel. At 1032 hours, due to Zuikaku having lost communication capabilities, Ozawa's flag was transferred to cruiser Oyodo; Ozawa's staff completed the transfer by 1100 hours. At 1308 hours, the third attack wave was sighted; this attack wave landed several torpedoes on Zuikaku, causing massive flooding and several fires in the hangar, leading to her being dead in the water by 1325 hours. In the lull of combat after the third wave, Captain Takeo Kaizuka ordered all survivors to the flight deck and addressed them one final time, letting them know that he would go down with the doomed ship. With a bugler playing the National Anthem, the ensign was lowered. The abandon ship order was formally given at 1358 hours. She rolled to port and sank by the stern at 1414 hours. Including Captain Kaizuka, 843 men died in Zuikaku's loss.

At 2015 hours, USS Cavalla made radar contact with the Japanese carrier fleet in the Philippine Sea; Commander Herman Kossler decided to sail away in order to surface later, at 2245 hours, to send the contact report to his superiors. Receiving this news, US Navy leadership ordered search planes to be sent to look for this carrier fleet, thus setting up for the subsequent Battle of the Philippine Sea.
18 Jun 1944	A search plane from Shokaku detected US Navy Task Force 58 in the Philippine Sea about 380 miles west of Yap Island in the Philippine Sea. At 2000 hours, as planned, the Japanese carrier fleet divided up in two.
19 Jun 1944	At dawn, flagship Taiho, Shokaku, and Zuikaku launched launched combat air patrol fighters. At 0756 hours, the first major strike force was launched (48 fighters, 53 bombers, and 27 torpedo bombers; led by Lieutenant Commander Akira Tarui). At 0810 hours, USS Albacore hit Taiho with a torpedo in the starboard bow, but Taiho's damage control team allowed the carrier to remain in formation; destroyer Hatsuzuki was left behind to hunt for USS Albacore. At 1020 hours, Zuikaku launched a second strike force (4 fighters and 4 bombers) to join the fourth big raid on on US Navy Task Force 58. Meanwhile, Taiho suspended flight operations due to gas vapor issues and Shokaku was busy with combat air patrol duties through well past 1100 hours. At 1100 hours, Shokaku began recovering 10 fighters; while the recovery process continued, at 1122, Shokaku 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 Shokaku 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. Carriers Zuikaku and Taiho were ordered to leave damaged Shokaku behind, while cruiser Yahagi and destroyer Urakaze remained with Shokaku. At 1350 hours, Shokaku strike planes returned, but were ordered away, redirected to Zuikaku and Taiho. By the time Taiho's aircraft returned, the gas vapor leak problem became extremely worrisome, and some of Taiho's aircraft were redirected to Zuikaku. At this time Captain Hiroshi Matsubara of Shokaku had ordered the carrrier abandoned 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. Shokaku 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 in the sinking of Shokaku. Light cruiser Yahagi and destroyers Urakaze and Hatsuzuki rescued Captain Hiroshi Matsubara among 570 other survivors. At 1432, another disaster struck as the gas vapor aboard Taiho detonated; the explosion engulfed the flagship. Zuikaku was ordered to proceed while Vice Admiral Jisaburo Ozawa to transferred his flag to cruiser Haguro. At the end of the day, the Japanese Navy lost 244 of the 374 aircraft that it had launched during this battle. The US Navy had only lost 20 aircraft.
20 Jun 1944	At 1130 hours, the Japanese Mobile Fleet, withdrawing west from the losses sustained on the previous day during the Battle of the Philippine Sea, paused to refuel from tankers while Vice Admiral Jisaburo Ozawa transferred his flag aboard Zuikaku. At 1500 hours, cruiser Atago reported seeing an American scout plane, and Ozawa ordered the refueling to be stopped and the fleet was to sail to the northwest at the speed of 24 knots. At 1725 hours, a large incoming American strike was detected. The Japanese mustered 17 fighters for defense, while the Haguro, Myoko, Yahagi, and seven destroyers formed a tight circle around Zuikaku. 95 American fighters, 54 torpedo bombers (most of which were armed with bombs rather than torpedoes), and 77 dive bombers from USS Hornet, USS Yorktown, and USS Belleau Wood arrived at 1730 hours, hitting Zuikaku once with a bomb, causing some damage.
22 Jun 1944	The Mobile Fleet, including Yamato, arrived at Nakagusuku Bay, Okinawa, Japan at 1300 hours. The survivors of Hiyo and Taiho were transferred to carrier Zuikaku from over-crowded cruiser and destroyers.

25 Oct 1944	Off northeastern Luzon, Philippines, aircraft from US Navy Task Force 38 attacked the Japanese carrier force consisted of fleet carrier Zuikaku and light carriers Zuiho, Chitose, and Chiyoda in the Battle off Cape Engaño. The Japanese force was escorted by two battleship-carrier hybrids (Hyuga and Ise; aircraft-less on this date), three light cruisers (Oyodo, Tama, and Isuzu), and nine destroyers at about 0830 hours, 26 minutes after those planes were detected by Zuikaku's radar. The overwhelmingly larger American force, under Admiral William Halsey, centered around fleet carriers USS Lexington, USS Intrepid, USS Essex, USS Franklin, USS Enterprise, further bolstered by a great many light carriers, battleships, cruisers, and destroyers. Zuikaku was damaged by skilled damage control teams extinguished the fires and corrected the listing by 0850 hours. Chitose was fatally damaged by the first attack wave, sinking at 0937 hours. At 0953 hours, a second attack wave struck, fatally damaging Chiyoda, leaving her dead in the water to be sunk by American destroyers later at 1655 hours. The second wave also damaged Zuiho's flight deck, the last functional flight deck of Vice Admiral Jisaburo Ozawa's force; Japanese combat air patrol planes in the air would need to ditch when they ran out of fuel. At 1032 hours, Ozawa transferred his flag from the damaged Zuikaku to Oyodo. At 1308, the Japanese sighted an incoming third wave of American aircraft. Six torpedoes struck Zuikaku, causing massive flooding and several fires in the hangar; the commanding officer addressed the surviving crew, ordered the lowering of the ensign, and gave the abandon ship order at 1358 hours; Zuikaku sank by the stern at 1414 hours. Zuiho suffered two torpedo, two bomb hits, and a great many near-misses during the third attack wave, and she was dead in the water at 1445 hours. At 1455 hours, a fourth wave struck, sealing the doom of Zuiho with ten near-misses, leading to Zuiho's commanding officer giving the abandon ship order; she sank at 1526 hours.
26 Aug 1945	Zuikaku was removed from the Japanese Navy List.
