Type 5 75 Mm Tank Gun
The ''Type 5 75 mm tank gun'' was used as the main armament of the Imperial Japanese Army prototype Type 4 Chi-To medium tank. It was one of the largest tank guns to be fitted on a World War II Japanese tank. Due to late war shortage-induced delays only two were ever mounted in a completed Type 4 Chi-To, neither of which saw combat use. The tank gun was also used on the prototype Type 5 Chi-Ri medium tank and prototype Type 5 Na-To tank destroyer. Design and use The Type 5 75 mm tank gun was intended as the main armament of the Type 4 Chi-To medium tank, a planned improvement over the Imperial Army's most powerful production tank, the Type 3 Chi-Nu. The first prototype Type 4 Chi-To was delivered in 1944. Though the most advanced and powerful Japanese tank to leave the drawing board, late war industrial and material shortages resulted in only two being completed. The long-barreled 75 mm L/56.4 (4.23 m) tank gun was a variant of the Japanese Type 4 75mm AA Gun, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Velocity
Muzzle velocity is the speed of a projectile ( bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''supersonic'' and thus can travel a substantial distance and even hit a target before a nearby observer hears the "bang" of the sho ...

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. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Occupation Of Japan
Japan was occupied and administered by the victorious Allies of World War II from the 1945 surrender of the Empire of Japan at the end of the war until the Treaty of San Francisco took effect in 1952. The occupation, led by the United States with support from the British Commonwealth and under the supervision of the Far Eastern Commission, involved a total of nearly 1 million Allied soldiers. The occupation was overseen by American General Douglas MacArthur, who was appointed Supreme Commander for the Allied Powers by US President Harry Truman; MacArthur was succeeded as supreme commander by General Matthew Ridgway in 1951. Unlike in the occupation of Germany, the Soviet Union had little to no influence over the occupation of Japan, declining to participate because it did not want to place Soviet troops under MacArthur's direct command. This foreign presence marks the only time in Japan's history that it has been occupied by a foreign power. However, unlike in Germany t ...

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to b ...

Chi-Ri
The ("Imperial Year 2605 Medium Tank Model 9") was a medium tank developed by the Imperial Japanese Army in World War II. It was intended to be a heavier, more powerful version of Japan's prototype Type 4 Chi-To medium tank. Only one incomplete prototype was built. History and development Based on battlefield information from the Eastern Front, the Department of Army Weaponry published a report demanding a shift of tank design focus from infantry-support tanks to tanks specialised for anti-tank missions. The Army's requirements for the new medium tank were an increase of weight from 20 tonnes to 35 tonnes and an armour upgrade from 50 mm to 75 mm. The new tank would be mounted with a new 75 mm tank gun instead of the previous 57 mm tank gun. Production focus would also prioritise quality over quantity. The new medium tank was designated as Type 5 Medium Tank Chi-Ri (五式中戦車 チリ). A single unarmed prototype of the Type 5 Chi-Ri was completed by May ...

Type 4 75mm AA Gun
The was an anti-aircraft gun developed by the Imperial Japanese Army. They started producing the gun in 1943. The Type 4 number was designated for the year the gun was accepted, 2604 in the Japanese imperial year calendar, or 1944 in the Gregorian calendar.War Department TM-E-30-480 ''Handbook on Japanese Military Forces'' September 1944 p 400 Due to the lack of raw materials available and the great damage by air raids to its industrial infrastructure, only 70 units were made. These units were retained for defense of the Japanese home islands during World War II. History and development In 1927, the Bofors company of Sweden had designed a new 75 mm AA gun which was purchased by the Royal Swedish Navy. This was developed into a mobile anti-aircraft gun with a carriage which had wheels, and was exported to the Republic of China, Persia, and Thailand. Japanese forces captured examples of the Bofors M29 75mm AA gun from the National Revolutionary Army of the Kuomintang governm ...

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 (''b ...

Type 3 Chi-Nu
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 ...
