Type 3 75 Mm Tank Gun
The Type 3 75 mm tank gun was used as the main armament of the Imperial Japanese Army Type 3 Chi-Nu medium tank. It was one of the largest guns ever to be fitted on a World War II Japanese tank. Design and use The Type 3 had a caliber of , barrel length of (L/38). As fitted to the Type 3 Chi-Nu medium tank, elevation was from -10 to +25 degrees. Firing a shell at a muzzle velocity of it gave an armor penetration of at and at . It shot a 6.6 kilogram projectile. This gun was based on the Japanese Type 90 field gun which in turn was loosely based on the French Schneider et Cie ''Canon de 85 mle 1927''. The Type 3 gun was license-built by the Osaka Arsenal. The Type 3 Chi-Nu, in which the gun was mounted, was the most powerful tank in regular series production for the Imperial Japanese Army during World War II. The Type 3 Chi-Nu was developed to cope with the M4 Sherman. By 1943, the low priority given to tank production meant that the Type 3 did not actually enter productio ...

Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

World War II Tank Guns
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tank Destroyer
A tank destroyer, tank hunter, tank killer, or self-propelled anti-tank gun is a type of armoured fighting vehicle, armed with a direct fire artillery gun or missile launcher, designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the first two decades of the 21st century has s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns ( tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

Type 3 Ho-Ni III
The was a tank destroyer and self-propelled artillery of Imperial Japanese Army in World War II. The Type 3 Ho-Ni III superseded the Type 1 Ho-Ni I and its variant the Type 1 Ho-Ni II in production, and gave better protection to the crew by having a completely enclosed superstructure. It was also meant to replace the Type 2 Ho-I for fire support. History and development Previous gun tanks, Type 1 Ho-Ni I and Type 2 Ho-I, were not really optimized designs. Type 1 Ho-Ni I and Type 1 Ho-Ni II both used an open casemate with frontal and side armour only for the main gun, which made the crew vulnerable in close combat situations. The Type 2 Ho-I, despite its enclosed rotating turret, was armed with a low-velocity howitzer more suitable against gun emplacements and fortifications. The fully enclosed and armored casemate of the Type 3 Ho-Ni III with the more powerful Type 3 75 mm tank gun was intended to address these issues, and an order of 57 was placed with Hitachi Ltd.

Japan Ground Self-Defense Force
The Japan Ground Self-Defense Force ( ja, 陸上自衛隊, Rikujō Jieitai), , also referred to as the Japanese Army, is the land warfare branch of the Japan Self-Defense Forces. Created on July 1, 1954, it is the largest of the three service branches. New military guidelines, announced in December 2010, direct the Japan Self-Defense Forces away from their Cold War focus on the Soviet Union to a new focus on China, especially in respect of the dispute over the Senkaku Islands. The JGSDF operates under the command of the chief of the ground staff, based in the city of Ichigaya, Shinjuku, Tokyo. The present chief of staff is General Yoshihide Yoshida.

Surrender Of Japan
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be wi ...

Type 3 Chi-Nu Medium Tank
was a medium tank of the Imperial Japanese Army in World War II. Like the Type 1 Chi-He, this tank was an improved version of the Type 97 Chi-Ha. It incorporated a Type 3 75 mm tank gun, one of the largest Japanese tank guns during the war. The Chi-Nu did not see combat during the war. All produced units were retained for the defense of the Japanese Homeland in anticipation of an Allied invasion. History and development At the outbreak of the Pacific War, the Type 97 Chi-Ha medium tank and Type 95 Ha-Go light tank designs comprised the mainstay of the armored units of the Imperial Japanese Army. As the war progressed, these tanks started to face significant challenges posed by Allied tanks. In the Burma and Philippines Campaigns, the firepower of the 57 mm cannon mounted on the Type 97 was proven to be insufficient against Allied tanks. The Imperial Japanese Army therefore developed the Type 1 47 mm tank gun, which used a lighter high-explosive round with greater armo ...

Operation Downfall
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day. Japan's geography made this invasion pl ...
