Type 97 57 Mm Tank Gun
The Type 97 57 mm tank gun was originally the main armament of the Imperial Japanese Army Type 97 Chi-Ha medium tank during the Second World War. Design and use The Type 97 Chi-Ha tank was the most widely produced Japanese medium tank of the war, although the armor protection was average for a 1930s tank.Zaloga, Steven J. ''Japanese Tanks 1939–45'', Osprey Publishing, 2007, p. 11. The 57 mm main gun, designed for infantry tank, infantry support, was a carry over from the 1933 Type 89 Chi-Ro, Type 89 medium tank. The gun was a short barrelled weapon with a relatively low muzzle velocity, which was sufficient for supporting the infantry. However, in 1939 during the Battle of Khalkhin Gol (Nomonhan) against Soviet Union, Soviet BT Tanks, the gun proved to be insufficient against the Soviet armor, causing the Japanese Army to have heavy tank losses. After ''Nomonhan'', new tank guns were developed for the Chi-Ha with a calibre of 47 mm - less than 57 mm tank g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ''T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HEAT
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armour-piercing Shot And Shell
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate either body armour or vehicle armour. From the 1860s to 1950s, a major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly-armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly-armoured targets such as body armour, bulletproof glass, and lightly-armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at very high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. History The late 1850s saw the development of the ironclad warship, which carried wrought iron armour of considerable thickness. This a ...

BT Tank
The BT tanks (russian: Быстроходный танк/БТ, translit=Bystrokhodnyy tank, lit. "fast moving tank" or "high-speed tank") were a series of Soviet light tanks produced in large numbers between 1932 and 1941. They were lightly armoured, but reasonably well-armed for their time, and had the best mobility of all contemporary tanks. The BT tanks were known by the nickname ''Betka'' from the acronym, or its diminutive ''Betushka''. The successor of the BT tanks was the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and medium tanks in service. Design The BT tanks were "convertible tanks". This was a feature that was designed by J. Walter Christie to reduce wear of the unreliable tank tracks of the 1930s. In about thirty minutes, the crew could remove the tracks and engage a chain drive to the rearmost road wheel on each side, allowing the tank to travel at very high speeds on roads. In wheeled mode, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 97 Chi-Ha
The was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, the Battles of Khalkhin Gol against the Soviet Union, and the Second World War. It was the most widely produced Japanese medium tank of World War II. The 57 mm main gun, designed for infantry support, was a carry over from the Type 89 I-Go medium tank. The suspension was derived from the Type 95 Ha-Go light tank, but used six road wheels instead of four. The 170 hp Mitsubishi air cooled diesel engine was a capable tank engine in 1938. The Type 97's low silhouette and semicircular radio antenna on the turret distinguished the tank from its contemporaries. After 1941, the tank was less effective than most Allied tank designs. In 1942, a new version of the Chi-Ha was produced with a larger three-man turret, and a high-velocity Type 1 47 mm tank gun. It was designated the Type 97-Kai or Type 97 ''Shinhōtō Chi-Ha'' ( ja, 新砲塔チハ; "New turret Chi-Ha"). History and de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
