Other crewmembers killed included 72 seamen, 68 mechanics, one maintenance man, and five clerks. [23], Akagi was completed with four Gihon geared steam turbine sets, each driving one propeller shaft, that produced a total of 131,000 shaft horsepower (98,000 kW). [17] This heavy gun armament was provided in case she was surprised by enemy cruisers and forced to give battle, but her large and vulnerable flight deck, hangars, and superstructure made her more of a target in any surface action than a fighting warship. [24], Akagi joined the Combined Fleet in August 1927 and was assigned to the First Carrier Division upon its formation on 1 April 1928, serving as the division's flagship under Rear Admiral Sankichi Takahashi. After completion of the refit, Akagi became a first-class reserve ship in December 1932. By early 1947, there were six fleet carriers flying the Japanese flag: one Shokaku -class, one Hayataka -class, and four Unryu -class ships. Instead, the vessel followed conventional wisdom regarding carriers and received a flat-top, inline flight deck with an offset starboard side island superstructure (with attached smoke funnel). 54–55; Parshall and Tully, pp. The forward flying decks retained post-conversion. carriers. During the day's actions, the carrier narrowly escaped damage when nine British Bristol Blenheim bombers from Ceylon penetrated the CAP and dropped their bombs from 11,000 feet (3,400 m), just missing the carrier and the heavy cruiser Tone. air cover for troop convoys. 1943; to 61 25 mm, 21 13.3 mm and 6 28-barrel AA rocket launchers in They were meant to be easily convertible to was needed for speed, but delayed the conversion and caused serious Thus, the guns could not be brought to bear directly forward or aft. [66], One of Akagi's torpedo bombers was launched to augment the search for any American ships that might be in the area. speed was 22-23 knots and the low hangar clearances were a serious Scrapped at completely re-engined; boiler exhuasts replaced by a downward-angled [69] This experience may well have contributed to Nagumo's determination to launch another attack on Midway, in direct violation of Yamamoto's order to keep the reserve strike force armed for anti-ship operations. Boiler exhausts were run aft to the scrapped 1947. The This group was very successful, sinking eight ships in the harbor there and none of Akagi's aircraft were lost. The forecastle had to be raised to overcome wetness induced by the [5] The rest of her guns were placed in reserve and scrapped in 1943. 72–76; Stille, p. 13; Goldstein and Dillon, pp. reconverted as a merchant ship. Akagi and the IJN's other carriers were initially given roles as tactical force multipliers supporting the fleet's battleships in the IJN's "decisive battle" doctrine. [78], Akagi reinforced the CAP with launches of three Zeros at 08:08 and four at 08:32. Published: 17-09-2020 £ 13.99. conversion, but sunk before this could be carried out. Often consideredthe first ship built from the keel up as a carrier, but was initially laiddown as a tanker and redesigned during construction. During World War 2, it was in service with the naval aviation. Aerial strikes against enemy carriers were later (beginning around 1932–1933) deemed of equal importance, with the goal of establishing air superiority during the initial stages of battle. Used as transport through 1944, then training carrier. 254–259; Peattie, p. 159; Werneth, p. 24, Parshall and Tully, pp. "[47] Japanese carrier anti-aircraft guns and associated fire-control systems had several design and configuration deficiencies that limited their effectiveness. Once preparations and training were completed, Akagi assembled with the rest of the First Air Fleet at Hitokappu Bay in the Kuril Islands on 22 November 1941.

Aircraft: 72 (91 maximum). fitted, but no hangar, catapults, etc. damaged and scrapped postwar. Served as For this trial, I chose something "easy", i.e. [54] On 5 April 1942, Akagi launched 17 B5Ns and 9 Zeros in an air strike against Colombo, Ceylon, which damaged the port facilities. Concept/Program: Large liners built under the "Shadow Program" and AA and some AA rocket launchers.

The only loss during the raid from Akagi's air group was one Zero shot down by AA fire and three damaged; four dive bombers were damaged, of which one could not be repaired. Design/Conversion: Hull essentially unchanged, except armor was [38], Akagi's modernization was completed on 31 August 1938.

Armor: 6 inch belt, 3 inch armored deck She displaced 26,900 long tons (27,300 t) at (standard) load, and 34,364 long tons (34,920 t) at full load, nearly 7,000 long tons (7,100 t) less than her designed displacement as a battlecruiser. fuel exploded on the flight deck and hangar deck, leading to Hiryū (飛龍, "Flying Dragon") was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the 1930s. [82] The landed aircraft were quickly struck below, while the carriers' crews began preparations to spot aircraft for the strike against the American carrier forces. for fitting out. Japan had given up the idea of achieving numerical fleet parity with the United States. operational service. 1945. previous class in role and design. Damaged at Eastern The entire crew complement for the ship numbered 1,751 men though over 2,100 were carried before the end. 151, 154; Stille, p. 59, Parshall and Tully, pp. [89][Note 7], At 10:29, Captain Aoki ordered the ship's magazines flooded. Thus, First Air Fleet air attacks would often consist of at least two massed waves of aircraft. completion. a relatively large island. to 9/1948. [39] She sailed for southern Chinese waters on 30 January 1939 and supported ground operations there, including attacks on Guilin and Liuzhou, until 19 February, when she returned to Japan. [13][15] The ship carried approximately 150,000 US gallons (570,000 l) of aviation fuel for her embarked aircraft. Departure from Service/Disposal: Hulk scrapped postwar.

Bombed by US aircraft at Midway 4 June 1942; munitions and their original role. Akagi was laid down as an Amagi-class battlecruiser at Kure, Japan, on 6 December 1920. Concept/Program: First large purpose-built Japanese aircraft carrier; On 9 April, she attacked Trincomalee with 18 B5Ns, escorted by 6 Zeros which claimed to have shot down 5 Hawker Hurricane fighters (only two of which can be confirmed from Allied records) without loss to themselves. by US aircraft at Midway 4 June 1942; munitions and fuel exploded on the hangar and flight deck were built, AA armament completely reworked, hulls AA armament completely reworked, hulls bulged, and exhausts routed into Submarine Albacore (SS-218) sinks Japanese new carrier Taiho, 180 nautical miles north-northwest of Yap. Modifications: By mid-1944 was fitted with an additional 20 25 mm Adding to the danger was the requirement of the Japanese carrier doctrine that aircraft be serviced, fueled, and armed whenever possible on the hangar decks rather than on the flight deck. Hulk scrapped 1946. They found only empty ocean, however, for the American carriers had immediately departed the area to return to Hawaii. This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942. The six airborne Akagi CAP Zeroes joined the other 15 CAP fighters currently aloft in destroying Waldron's planes. Departure from Service/Disposal: Never became operational; sunk Reconstructed at Sasebo Navy Yard 1934-1935. remainder of the war. They used This process normally took about an hour and a half; more time would be required to bring the aircraft up to the flight deck, warm up and launch the strike group. Eagle – cancelled; Africa – to Malta class then cancelled; Majestic class. The ship was named after Mount Akagi, following the Japanese ship-naming conventions for battlecruisers. He retired from the navy in October 1942 but was recalled to service a year later, and survived the war. Nagumo's chief of staff, Rear Admiral. Unryu was ordered under the 1941 fleet program, followed by a sister ship. Operational: Zuiho participated in many wartime Modifications: The island was removed in 1923 due to interference During the first six months of the Pacific War, the IJN wreaked havoc in the southwestern Pacific and the Indian Ocean. demolished down to the main deck, a hangar and flight deck were built, As it was she was built to 22000t when the treaty limit ended up being 23000t. 42–43, Lengerer, pp. Subsequent attack waves consisted of the next deckload of aircraft. while serving as a decoy. [37], Several major weaknesses in Akagi's design were not rectified. [46], Although the concentration of so many fleet carriers into a single unit was a new and revolutionary offensive strategic concept, the First Air Fleet suffered from several defensive deficiencies that gave it, in Mark Peattie's words, a "'glass jaw': it could throw a punch but couldn't take one. up and operated ashore for a period; rejoined the ship late 1942. AIRCRAFT CARRIERS. Departure from Service/Disposal: None ever deployed operationally. As a result, the ship was vulnerable to attack by dive bombers. view of the critical need for carriers. [11] Akagi's main flight deck was 190.2 meters (624 ft 0 in) long and 30.5 meters (100 ft) wide,[12] her middle flight deck (beginning right in front of the bridge) was only 15 meters (49 ft 3 in) long and her lower flight deck was 55.02 meters (180 ft 6 in) long. Used as repatriation ship postwar. She was extensively used for experimental, trialsand development work. In general, Japanese carrier design stressed speed and aircraft capacity as they were seen as purely offensive weapons. enlarging an existing design, the Japanese cruiser DDH-181 made by Crazyhorse. Concept/Program: A large battleship hull of the Yamato armament, partially in turrets and partially in casemates. Design/Conversion: These ships had been modified in 1941 to carry The second Japanese aircraft carrier to enter service, and the first large or "fleet" carrier, Akagi and the related Kaga figured prominently in the development of the IJN's new carrier striking force doctrine that grouped carriers together, concentrating their air power. [18][Note 1], The ship carried dedicated anti-aircraft armament of six twin 45-caliber 12 cm 10th Year Type gun mounts fitted on sponsons below the level of the funnels, where they could not fire across the flight deck, three mounts per side. Departure from Service/Disposal: Lost during the Guadalcanal It was at this time, around 10:20, that in the words of Jonathan Parshall and Anthony Tully, the "Japanese air defenses would finally and catastrophically fail. Departure from Service/Disposal: Both sunk by submarines in Eight ships were sunk, including the American destroyer Peary, and fourteen more were damaged. In fleet training exercises, the carriers began to operate together in front of or with the main battle line. forward flying decks and modernize the ship. The Shinano would become the next step in the evolution of the aircraft carrier, Japanese commanders thought at the time. All told, the Taiho became the most technologically advanced Japanese carrier of … Specifications following reconstruction The carrier's early career was uneventful, consisting of various training exercises. One of Bombed at Kure by US aircraft 24 June 1945, grounded to Akagi's aviation fuel tanks were incorporated directly into the structure of the carrier, meaning that shocks to the ship, such as those caused by bomb or shell hits, would be transmitted directly to the tanks, resulting in cracks or leaks. In her new configuration, the carrier embarked 12 Mitsubishi A5M Type 96 "Claude" fighters with four disassembled spares, 19 Aichi D1A "Susie" dive bombers with five spares, and 35 Yokosuka B4Y "Jean" horizontal/torpedo bombers with 16 spares. With this class, Japan returned to its original carrier designs roots. Japanese military sources confirmed that the possibility of operating fixed wing aircraft was incorporated into the design of the ships from the earliest stages of the Izumo program, but this was not made public because Article 9 of the Japanese Constitution prohibits Japan from possessing offensive military weapons such as aircraft carriers. The second bomb, likely dropped by Best, landed at the aft edge of the middle elevator and detonated in the upper hangar. [25], Akagi was reduced to second-class reserve status on 1 December 1931 in preparation for a short refit in which her arresting gear was replaced and her radio and ventilation systems were overhauled and improved. 12/1944 with serious damage; not fully repaired, laid up for the No catapults were fitted. [Note 8] Akagi stopped dead in the water at 13:50 and her crew, except for Captain Taijiro Aoki and damage-control personnel, was evacuated. the main deck up with dual hangars (restricted in height to reduce [16], As originally completed, Akagi carried an air group of 28 Mitsubishi B1M3 torpedo bombers, 16 Nakajima A1N fighters and 16 Mitsubishi 2MR reconnaissance aircraft. Japanese aircraft carriers have good maneuverability and concealment values, allowing them to re-position and evade enemies exceptionally well. Six of the Zeros were intended to be stationed on Midway after the invasion and belonged to the 6th Air Group. Torpedoed and sunk loss. A starboard-side island Many were incomplete at the end of the war; the survivors and hulks were class taken over for conversion to a carrier. USS Langley , the U.S. Navy's first aircraft carrier, 1927. Sunk by seven bombs and seven torpedoes South Korea’s Navy has shared images of the country’s first aircraft carrier. ... have most likely resigned the crummy ole US Navy to join the British Navy in hopes of learning something about superior aircraft carrier design. Propulsion: Steam turbines, 19 boilers, 4 shafts, 133,000 shp, 31.2 knots Due to these qualities, it was a symbol of Japanese naval aviation. May 1942. fifth Yamato, modified into a semi-carrier design while under construction. Upon the formation of the First Air Fleet or Kido Butai (Striking Force) in early 1941, she became its flagship, and remained so for the duration of her service. [55] Four of the Blenheims were subsequently shot down by CAP fighters and one was shot down by aircraft from the carriers' returning air strike. At the time, Japan was constructing a single, keel-up, purpose-built aircraft carrier. armored flight deck, large island. partially in casemates. 15–16; Willmott, p. 415; Parshall and Tully, p. 245. [103] In an effort to conceal the defeat, Akagi was not immediately removed from the Navy's registry of ships, instead being listed as "unmanned" before finally being struck from the registry on 25 September 1942. Japanese aircraft carrier Akagi in a series of fly-around 3D animations. The carrier Kaga discovered on October 16 was the first sunken Japanese aircraft carrier to ever be found. Completed without an Akagi and Kaga were given different solutions to evaluate in real-world conditions. Akagi and the other carriers shortly abandoned the chase and dropped anchor at Hashirajima anchorage on 22 April. The new Carrier-based aircraft typically need a rolling start, aided by a catapult or ski ramp, to get airborne, though some aircraft such as the Harrier or F-35B Joint Strike Fighter can take off vertically.
