252 Air Group
was a fighter aircraft unit of the Imperial Japanese Navy (IJN) during the Pacific campaign of World War II. The unit was formed on 1 November 1942 by separating the fighter squadron from the Genzan Air Group. The unit, equipped with A6M Zero fighter aircraft, was involved in several major battles in the south and central Pacific from 1942 to 1943, including the Battle of the Bismarck Sea. After being annihilated in combat over the Marshall Islands in 1943, the unit was reconstituted in Japan in February 1944 and helped defending the home islands against Allied An alliance is a relationship among people, groups, or states that have joined together for mutual benefit or to achieve some common purpose, whether or not explicit agreement has been worked out among them.

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ...

Kōkūtai
A ''Kōkūtai'' () was a term used by the Imperial Japanese Navy Air Service (IJNAS) to designate a military aviation unit, similar to the Air Groups in other air arms and services of the time. (''Group'' in the British Royal Air Force, ''Gruppe'' in the German Luftwaffe, ''Groupe'' in the French Armée de l'Air etc.) A Kōkūtai could be based at land or on board aircraft carriers and could contain up to hundreds of men and aircraft. For example, the famous 343 Kōkūtai was a land based fighter group while the 652nd Kōkūtai was a carrier-based bomber group. Kōkūtai were divided into smaller units called Hikōtai, which were the equivalent of a squadron. Kōkūtai were usually divided into three Hikōtai. In general, most pilots and aircrew in the Imperial Japanese Navy Air Service were non-commissioned officers. The word Kōkūtai is abbreviated with the abbreviation "Ku" (空). 343 Ku, for example, stands for 343 Kōkūtai. In the Imperial Japanese Army Air Service (IJAA ...

Japanese Air Attacks On The Mariana Islands
During World War II, a series of Japanese air attacks on the Mariana Islands took place between November 1944 and January 1945. These raids targeted United States Army Air Forces (USAAF) bases and sought to disrupt the bombing of Japan by B-29 Superfortress heavy bombers operating from the islands. The Japanese lost 37 aircraft during this operation, but destroyed 11 B-29s and damaged a further 43. Preparations were also made for commando raids on the bases in early and mid-1945 but these did not go ahead. While the attacks on the Mariana Islands did not seriously disrupt the USAAF air campaign, they had an effect on other American operations. After determining that the Japanese raiders were staging through Iwo Jima, American forces stepped up their attacks on that island. While the decision to invade Iwo Jima had been made before the raids commenced, stopping the attacks formed part of the justification for the landing. In addition, further air defense units were deployed to the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by 1941 were the United Kingdom, United States, Soviet Union, and China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, France, and Poland, as well as their respective dependencies, such as British India. They were soon joined by the independent dominions of the British Commonwealth: Canada, Australia, New Zealand and South Africa. Consequently, the initial alliance resembled that of the First World War. As Axis forces began invading northern Europe and the Balkans, the Allies added the Netherlands, Belgium, Norway, Greece, and Yugoslavia. The Soviet Union, which initially had a nonaggression pa ...

Battle Of The Bismarck Sea
The Battle of the Bismarck Sea (2–4 March 1943) took place in the South West Pacific Area (SWPA) during World War II when aircraft of the U.S. Fifth Air Force and the Royal Australian Air Force (RAAF) attacked a Japanese convoy carrying troops to Lae, New Guinea. Most of the Japanese task force was destroyed, and Japanese troop losses were heavy. The Japanese convoy was a result of a Japanese Imperial General Headquarters decision in December 1942 to reinforce their position in the South West Pacific. A plan was devised to move some 6,900 troops from Rabaul directly to Lae. The plan was understood to be risky, because Allied air power in the area was strong, but it was decided to proceed because otherwise the troops would have to be landed a considerable distance away and march through inhospitable swamp, mountain and jungle terrain without roads before reaching their destination. On 28 February 1943, the convoy – comprising eight destroyers and eight troop transports with ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pacific War
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in Asia, the Pacific Ocean, the Indian Ocean, and Oceania. It was geographically the largest theater of the war, including the vast Pacific Ocean theater, the South West Pacific theater, the Second Sino-Japanese War, and the Soviet–Japanese War. The Second Sino-Japanese War between the Empire of Japan and the Republic of China had been in progress since 7 July 1937, with hostilities dating back as far as 19 September 1931 with the Japanese invasion of Manchuria. However, it is more widely accepted that the Pacific War itself began on 7 December (8 December Japanese time) 1941, when the Japanese simultaneously invaded Thailand, attacked the British colonies of Malaya, Singapore, and Hong Kong as well as the United States military and naval bases in Hawaii, Wake Island, Guam, and the Philippines. The Pacific War saw the Allies pitted against Japan, the latter ai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Japan Campaign
The Japan campaign was a series of battles and engagements in and around the Japanese home islands, between Allied forces and the forces of Imperial Japan during the last stages of the Pacific campaign of World War II. The Japan campaign lasted from around June 1944 to August 1945. Air war Periodic air raids on Japan were the first attacks undertaken by Allied forces. In late 1944, these raids were followed by a major strategic bombing of cities, factories, and other war infrastructure throughout Japan, most notably: * Operation Meetinghouse raid on Tokyo (9-10 March 1945): 100,000 Japanese were killed, mostly civilians, including in the conflagration that followed the firebombing. * Bombing of Kure (24-28 July 1945): Most of the surviving large Japanese warships were lost, leaving the ''Nagato'' as the only remaining capital ship in Japan's inventory. * Atomic bombing of Hiroshima (6 August 1945): Of approximately 90,000–140,000 deaths, 20,000 were Japanese combatants and ...

Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, when it was dissolved following Japan's surrender in World War II. The Japan Maritime Self-Defense Force (JMSDF) was formed between 1952–1954 after the dissolution of the IJN. The Imperial Japanese Navy was the third largest navy in the world by 1920, behind the Royal Navy and the United States Navy (USN). It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet. It was the primary opponent of the Western Allies in the Pacific War. The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent, beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery.

Gilbert And Marshall Islands Campaign
The Gilbert and Marshall Islands campaign were a series of battles fought from August 1942 through February 1944, in the Pacific theatre of World War II between the United States and Japan. They were the first steps of the drive across the central Pacific by the United States Pacific Fleet and Marine Corps. The purpose was to establish airfields and naval bases that would allow air and naval support for upcoming operations across the Central Pacific. Operation ''Galvanic'' and Operation ''Kourbash'' were the code names for the Gilberts campaign (in modern Kiribati) that included the seizures of Tarawa and Makin, during the Battle of Tarawa of 20–23 November and the Battle of Makin of 20–24 November 1943. Operation ''Flintlock'' and Operation ''Catchpole'' were aimed at capturing Japanese bases at Kwajalein, Eniwetok, and Majuro in the Marshall Islands.
