The First Carrier Division (第一航空戦隊, Dai Ichi Kōkū sentai, often abbreviated as 一航戦 Ichikō-sen) was an aircraft carrier unit of the Imperial Japanese Navy's First Air Fleet. At the beginning of the Pacific Campaign of World War II, the First Carrier Division consisted of the fleet carriers Akagi and Kaga. The division participated in the Attack on Pearl Harbor and Indian Ocean Raid. After Akagi and Kaga were sunk at the Battle of Midway in June 1942, carriers Shōkaku, Zuikaku, and Zuihō were redesignated as the First Carrier Division.

The First Carrier Division participated in the largest carrier-to-carrier battle in history, the Battle of the Marianas, and specifically the aircraft carrier Battle of the Philippine Sea (the so-called “Great Marianas Turkey Shoot”) on 19–20 June, where the Japanese naval forces were decisively defeated with heavy and irreplaceable losses to their carrier-borne and land-based aircraft. [1] As a result of the massive losses suffered to her airgroup, Zuikaku would play a support role in the Japanese fleet from this point on, up until her sinking during the Battle of Leyte Gulf.
The Battle of Midway was a major naval battle in the Pacific Theater of World War II that took place 4–7 June 1942, six months after Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The U.S. Navy under Admirals Chester W. Nimitz, Frank J. Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chūichi Nagumo, and Nobutake Kondō north of Midway Atoll, inflicting devastating damage on the Japanese fleet. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare", while naval historian Craig Symonds called it "one of the most consequential naval engagements in world history, ranking alongside Salamis, Trafalgar, and Tsushima Strait, as both tactically decisive and strategically influential."
Hiryū was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the 1930s. Generally regarded as the only ship of her class, she was built to a modified Sōryū design. Her aircraft supported the Japanese invasion of French Indochina in mid-1940. She took part in the attack on Pearl Harbor and the Battle of Wake Island. During the first few months of the Pacific War, the ship supported the conquest of the Dutch East Indies in January 1942. The following month, her aircraft bombed Darwin, Australia; and continued to assist in the Dutch East Indies campaign. In April, Hiryū's aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean Raid.
Kaga was an aircraft carrier built for the Imperial Japanese Navy (IJN). Originally intended to be one of two Tosa-class battleships, Kaga was converted under the terms of the Washington Naval Treaty to an aircraft carrier as the replacement for the battlecruiser Amagi, which had been irreparably damaged during the 1923 Great Kantō earthquake. Kaga was rebuilt in 1933–1935, increasing her top speed, improving her exhaust systems, and adapting her flight decks to accommodate more modern, heavier aircraft.
Shōkaku was the lead ship of her class of two aircraft carriers built for the Imperial Japanese Navy (IJN) shortly before the Pacific War. Along with her sister ship Zuikaku, she took part in several key naval battles during the war, including the attack on Pearl Harbor, the Battle of the Coral Sea, and the Battle of the Santa Cruz Islands, before being torpedoed and sunk by the U.S. submarine USS Cavalla at the Battle of the Philippine Sea.
Sōryū was an aircraft carrier built for the Imperial Japanese Navy (IJN) during the mid-1930s. A sister ship, Hiryū, was intended to follow Sōryū, but Hiryū's design was heavily modified and she is often considered to be a separate class. Sōryū's aircraft were employed in operations during the Second Sino-Japanese War in the late 1930s and supported the Japanese invasion of French Indochina in mid-1940. During the first months of the Pacific War, she took part in the attack on Pearl Harbor, the Battle of Wake Island, and supported the conquest of the Dutch East Indies. In February 1942, her aircraft bombed Darwin, Australia, and she continued on to assist in the Dutch East Indies campaign. In April, Sōryū's aircraft helped sink two British heavy cruisers and several merchant ships during the Indian Ocean raid.
Zuikaku was the second and last Shōkaku-class aircraft carrier built for the Imperial Japanese Navy (IJN) shortly before the beginning of the Pacific War. Zuikaku was one of the most capable Japanese aircraft carriers of the entire war.
Akagi was an aircraft carrier built for the Imperial Japanese Navy (IJN). Though she was laid down as an Amagi-class battlecruiser, Akagi was converted to an aircraft carrier while still under construction to comply with the terms of the Washington Naval Treaty. The ship was rebuilt from 1935 to 1938 with her original three flight decks consolidated into a single enlarged flight deck and an island superstructure. 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. This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942.
Chūichi Nagumo was an admiral in the Imperial Japanese Navy (IJN) during World War II. Nagumo led Japan's main carrier battle group, the Kido Butai, in the attack on Pearl Harbor, the Indian Ocean raid and the Battle of Midway. He never recovered from the crushing defeat at Midway, and committed suicide during the Battle of Saipan.
The Battle of the Philippine Sea was a major naval battle of World War II on 19–20 June 1944 that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. This was the largest carrier-to-carrier battle in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft.
USS Mindoro was a Commencement Bay-class escort carrier of the United States Navy. The ship was a converted oil tanker, and she had a capacity to carry up to thirty-three aircraft. She was built during World War II, but was completed too late to see action during the conflict. She nevertheless saw service with the 8th Fleet in the late 1940s and early 1950s in the Atlantic Ocean. She also made two deployments to the Mediterranean Sea, in 1950 and 1954, before being decommissioned in January 1955 and assigned to the Atlantic Reserve Fleet. She was retained for just four years before being struck from the naval register in December 1959 and thereafter scrapped.
Vice-Admiral Jisaburō Ozawa was an admiral in the Imperial Japanese Navy during World War II. Ozawa held several important commands at sea throughout the duration of the conflict.
The Imperial Japanese Navy Air Service (IJNAS) was the air arm of the Imperial Japanese Navy (IJN). The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War.
Zuihō was the name ship of her class of two light aircraft carriers built for the Imperial Japanese Navy. Originally laid down as the submarine tender Takasaki, she was renamed and converted while under construction into an aircraft carrier. The ship was completed during the first year of World War II and played a minor role in the Battle of Midway in mid-1942. She participated in the Guadalcanal Campaign during the rest of 1942. Significantly damaged during the Battle of the Santa Cruz Islands in that campaign, after repairs Zuihō covered the evacuation of Japanese forces from Guadalcanal in early 1943.
The 1st Air Fleet, also known as the Kidō Butai, was a name used for a combined carrier battle group comprising most of the aircraft carriers and carrier air groups of the Imperial Japanese Navy (IJN) during the first eight months of the Pacific War.
The Shōkaku class consisted of two aircraft carriers built for the Imperial Japanese Navy (IJN) in the late 1930s. Completed shortly before the start of the Pacific War in 1941, the Shōkaku and Zuikaku were called "arguably the best aircraft carriers in the world" when built. With the exception of the Battle of Midway, they participated in every major naval action of the Pacific War, including the attack on Pearl Harbor, the Indian Ocean Raid, the Battle of the Coral Sea, the Guadalcanal Campaign, the Battle of the Philippine Sea and the Battle of Leyte Gulf.
The Zuihō class (瑞鳳型), also known as the Shōhō class (祥鳳型), consisted of two aircraft carriers built for the Imperial Japanese Navy (IJN) before World War II, the Zuihō and Shōhō. Both ships were originally built as submarine tenders, but were subsequently converted into carriers. Completed in early 1942, Shōhō supported the invasion forces in Operation MO, the invasion of Port Moresby, New Guinea, and was sunk by American carrier aircraft on her first combat operation during the Battle of the Coral Sea on 7 May. Shōhō was the first Japanese aircraft carrier to be sunk during World War II. Zuihō played a secondary role in the Battle of Midway in mid-1942 and did not engage any American aircraft or ships during the battle. The ship participated in the Guadalcanal campaign during the rest of 1942. She was lightly damaged during the Battle of the Santa Cruz Islands during this campaign and covered the evacuation of Japanese forces from the island in early 1943 after repairs.
The Fifth Carrier Division was an aircraft carrier unit of the Imperial Japanese Navy's First Air Fleet. At the beginning of the Pacific Campaign of World War II, the Fifth Carrier Division consisted of the fleet carriers Shōkaku and Zuikaku. These two ships participated in the attack on Pearl Harbor, using their aircraft to strafe airfields and provide fighter protection for bombers. On the way back to Japan after Pearl Harbor, the 5th Carrier Division was used to protect the main fleet from American submarines suspected of following the fleet.
The Chitose-class aircraft carriers were a class of two seaplane tenders, later converted to light aircraft carriers, of the Imperial Japanese Navy during World War II. Under the terms of the Washington Naval Treaty, the total tonnage of Japan's naval vessels was limited by class. The Chitose-class ships were built as seaplane tenders, designed to make the conversion to aircraft carriers relatively easy. They served as seaplane tenders during the early part of the Pacific War. After the Battle of Midway, they were converted into light aircraft carriers. Both ships participated in the Battle of the Philippine Sea and both were sunk in the Battle of Leyte Gulf.
Shigeharu Murata was a torpedo bomber pilot officer in the Imperial Japanese Navy (IJN) during World War II. He was the commander of torpedo bombers in the Attack on Pearl Harbor that crippled several United States Navy (USN) battleships and during the Battle of the Santa Cruz Islands that resulted in the sinking of carrier Hornet. He was killed in action during the Battle of the Santa Cruz Islands.
Ayao Shirane was a fighter ace in the Imperial Japanese Navy (IJN) during World War II. He participated in various battles and campaigns throughout the Pacific War and was eventually shot down and killed over Leyte, Philippines on 24 November 1944. He was officially credited with destroying nine enemy aircraft.
