Type 5 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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Tanks Of Japan
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] |
Jagdtiger
The ''Jagdtiger'' ("Hunting Tiger"; officially designated ''Panzerjäger Tiger Ausf. B'') is a German casemate-type heavy tank destroyer (''Jagdpanzer'') of World War II. It was built upon the slightly lengthened chassis of a Tiger II. Its ordnance inventory designation was Sd.Kfz. 186. The 71-tonne ''Jagdtiger'' was the heaviest armored fighting vehicle (AFV) used operationally by any nation in WWII and the heaviest combat vehicle of any type to be produced during the conflict. it was armed with a 128 mm Pak 44 L/55 main gun which could out-range and defeat any AFV fielded by the Allied forces. It saw brief service in small numbers from late 1944 until the end of the war on both the Western and Eastern Front. Although 150 were ordered, only around 80 were produced. Due to an excessive weight and an underpowered drivetrain system, the ''Jagdtiger'' was plagued with mobility and mechanical problems. Three ''Jagdtigers'' survive in museums.

Elefant
The ''Elefant'' (German for "elephant") was a heavy tank destroyer used by German Wehrmacht Panzerjäger during World War II. Ninety-one units were built in 1943 under the name Ferdinand, after its designer Ferdinand Porsche, using VK 45.01 (P) tank hulls produced for the Tiger I tank design abandoned in favour of a Henschel design. In January to April 1944, ''Ferdinands'' received modifications and upgrades. They were renamed ''Elefant'' in May 1944. The official German designation was ''Panzerjäger Tiger'' (P)Not to be confused with either the ''Panzerkampfwagen VI Tiger Ausf. H'' or ''Ausf. E'' versions of the Tiger I, or the ''Panzerkampfwagen Tiger Ausf. B'' (Tiger II) and the ordnance inventory designation was ''Sd.Kfz.'' 184. Development history Porsche GmbH had manufactured about 100 chassis for their unsuccessful proposal for the Tiger tank, the " Porsche Tiger", in the Nibelungenwerk factory in Sankt Valentin, Austria. Both the successful Henschel proposal and t ... [...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] |
Experimental Type 5 Gun Tank Ho-Ri Mock-up Scale Model 01
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
