Imperial Japanese Navy's Unryū class aircraft carrier

The '''Japanese aircraft carrier Unryū''' (雲龍) was the lead ship of her class of fleet aircraft carriers built for the Imperial Japanese Navy (IJN) during World War II. She was commissioned in mid 1944, but fuel and aircrew shortages limited her use to Japanese waters. The impending American invasion of Luzon caused the IJN to order her to transport aircraft and supplies to the Philippines in December. The ship was torpedoed and sunk by the American submarine Redfish in the East China Sea during the voyage.

The last purpose built Japanese carrier construction was a group of vessels based on an improved Japanese aircraft carrier Hiryū design, but with individual units differing in detail reflecting the changing circumstances as the conflict in the Pacific approached its conclusion. Unryū was ordered, under the provisional name of #302, as part of the Rapid Naval Armaments Supplement Programme of 1941. The ship was one of 16 Unryū class aircraft carriers planned, although only three were completed before the end of the war.|group=Note

Unryū had a length of overall. She had a beam of and a draft of She displaced Her crew consisted of 1,595 officers and men. The ship used the same turbines and boilers as used in the heavy cruiser Japanese cruiser Suzuya. These consisted of four geared steam turbine sets with a total of , each driving one shaft, using steam provided by eight Kampon Type B water tube boilers. The ship had a designed speed of Unryū carried of fuel oil which gave her a range of at .

Unryūs flight deck was long and had a maximum width of A small island was mounted well forward on the starboard side and contained the ship's bridge and air operations control center. It was fitted with a small tripod mast that mounted one of the ship's radar antennas. The ship was designed with two superimposed hangars that were served by two aircraft elevators, each ; the center elevator as used in Hiryū was deleted to simplify construction and reduce stress in the hull. The elevators had a maximum capacity of and took 19 seconds to go from the lower hangar to the flight deck. Unryū was fitted with hydraulically operated Type 3 arresting gear with nine cables. She also mounted three Type 3 crash barricades. No aircraft catapult was fitted. The ship mounted a retractable crane on the starboard side of the flight deck, just aft of the rear elevator. Unryū carried of aviation gasoline for her aircraft. The ship's air group was originally intended to consist of 12 Mitsubishi A6M Zero fighters, plus 3 in storage, 27 Aichi D3A Val dive bombers, plus 3 in reserve, and 18 Nakajima B5N "Kate" torpedo bombers plus 2 in crates. Unryūs hangars could not accommodate so many aircraft so 11 planes were planned to be permanently carried on the flight deck. In 1943 the air group was revised to consist of 18 Mitsubishi A7M "Sam" fighters (+2 in storage), 27 Yokosuka D4Y "Judy" dive bombers and 6 Nakajima C6N "Myrt" reconnaissance aircraft. Of these, the C6Ns were intended to be carried on the flight deck. When the ship was commissioned in 1944, neither the A7M nor the C6Ns were yet in service, so the air group was reconfigured to consist of 27 Zeros, 12 D4Ys, 3 of which were to be the reconnaissance version, and 9 Nakajima B6N "Jill" torpedo bombers. By this time, however, the shortage of carrier qualified aircrew was such that they were ordered to operate from shore bases and Unryū never embarked her full air group.

Unryūs waterline armored belt was thick over her machinery spaces, but this increased to over her magazines. Her deck armor above the machinery was thick, but the armor above the magazines was thick. The ship's primary armament consisted of a dozen 40 caliber 12.7 cm (5 in) Type 89 anti aircraft (AA) guns in twin mounts on sponsons on the ship's sides. Unryū was initially equipped with 16 triple 25 mm (1 in) Type 96 and 3 single Type 96 AA gun mounts, most on sponsons along the sides of the hull. These guns were supplemented by six 28 round AA rocket launchers. Shortly after completion, another 4 triple and 13 single 25 mm mounts were added. For defense against submarines, the carrier was fitted with six depth charge throwers and carried between six and ten depth charges for them. A Type 3 sonar and a Type 93 hydrophone were fitted to detect any submarines.

Unryū was laid down at Yokosuka Naval Arsenal on 1 August 1942 and launched on 25 September 1943. Upon commissioning on 6 August 1944, she was assigned to the 3rd Fleet. She underwent shakedown and trials within Tokyo Bay through mid September, and was then transferred to Kure Naval District, from which she made numerous training runs around the Seto Inland Sea until December. From 30 October to 7 November, she served briefly as the flagship of Vice Admiral Jisaburo Ozawa’s Mobile Fleet. Eight days later, the Mobile Fleet was disbanded and the ship was transferred to Carrier Division 1. Later that month, some A6Ms and B6Ns were embarked.

On 13 December 1944, thirty Yokosuka MXY7 Ōhka kamikaze rocket planes were loaded aboard Unryū for transport to Manila in the Philippines. Four days later, on 17 December 1944, Unryū departed Kure, Hiroshima escorted by the destroyers Japanese destroyer Shigure, Japanese destroyer Hinoki, and Japanese destroyer Momi under the overall command of Captain Konishi. Her maiden sea voyage was a vain attempt to reinforce the garrison on the island of Luzon just prior to the Allied landings there. Unryū was struck from the Navy List on 20 February 1945.
