VK 30.01 (H)
The VK 30.01 (H) is a German prototype heavy tank developed by Henschel in Germany during World War II. It was rejected for production likely due to being outdated by the time it was meant to be produced. The chassis from this project went on to form the chassis for the Sturer Emil self-propelled anti-tank gun project. Development In 1937 the German Army Ordnance Office (''Heereswaffenamt'') had ordered the design of 30-tonne tanks from Henschel, MAN SE, and Daimler-Benz that would succeed the Panzer IV medium tank for infantry support, and was to be produced by Krupp. To that end it would carry either the same short-barrelled 7.5 cm KwK 37 gun of the Panzer IV or a tank-mounted version of the 10.5cm leFH18/40 L/28 howitzer. In October 1941, Krupp was asked if the 7.5 cm KwK 40 could be mounted, but the answer was negative, not without many modifications. Alternatively, the long barreled 5 cm KwK 39 or L/50 was able to be mounted instead of the short 7.5cm cannon or the 10.5cm ...

Omaha Beach
Omaha Beach was one of five beach landing sectors designated for the amphibious assault component of operation Overlord during the Second World War. On June 6, 1944, the Allies invaded German-occupied France with the Normandy landings. "Omaha" refers to an section of the coast of Normandy, France, facing the English Channel, from east of Sainte-Honorine-des-Pertes to west of Vierville-sur-Mer on the right bank of the Douve River estuary. Landings here were necessary to link the British landings to the east at Gold with the American landing to the west at Utah, thus providing a continuous lodgement on the Normandy coast of the Bay of the Seine. Taking Omaha was to be the responsibility of United States Army troops, with sea transport, mine sweeping, and a naval bombardment force provided predominantly by the United States Navy and Coast Guard, with contributions from the British, Canadian and Free French navies. The primary objective at Omaha was to secure a beachhead deep, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Tank
Heavy tank is a term used to define a class of tanks produced from World War I through the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes. Role Heavy tanks achieved their greatest, albeit limited, success when fighting lighter tanks and destroying fortifications. Heavy tanks often saw limited combat in their intended roles, instead becoming mobile pillboxes or defensive positions, such as the German Tiger designs, or the Russian KV designs Design Heavy tanks feature very heavy armor and weapons relative to lighter tanks. Many heavy tanks shared components from lighter tanks. For example, the M103 heavy tank shared many components with lighter Patton tanks, including transmission and engine. As a result, they tend to be either underpowered and comparatively slow, or have engine and drive train reliability issues. In case of an entirely new design deve ...

MG 34
The MG 34 (shortened from German: ''Maschinengewehr 34'', or "machine gun 34") is a German recoil-operated air-cooled general-purpose machine gun, first tested in 1929, introduced in 1934, and issued to units in 1936. It introduced an entirely new concept in automatic firepower – the ''Einheitsmaschinengewehr'' (Universal machine gun) – and is generally considered the world's first general-purpose machine gun (GPMG). Both the MG 34 and MG 42 were erroneously nicknamed "Spandau" by Allied troops, a carryover from the World War I nickname for the MG 08, which was produced at the Spandau Arsenal. The versatile MG 34 was chambered for the full-power 7.92×57mm Mauser rifle cartridge, and was arguably the most advanced machine gun in the world at the time of its deployment. The MG 34 was envisaged and well developed to provide portable light and medium machine gun infantry cover, anti-aircraft coverage, and even sniping ability. Its combination of exceptional mobility – being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Henschel
Henschel & Son (german: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons. Georg Christian Carl Henschel founded the factory in 1810 at Kassel. His son Carl Anton Henschel founded another factory in 1837. In 1848, the company began manufacturing locomotives. The factory became the largest locomotive manufacturer in Germany by the 20th century. Henschel built 10 articulated steam trucks, using Doble steam designs, for Deutsche Reichsbahn railways as delivery trucks. Several cars were built as well, one of which became Hermann Göring's staff car. In 1935 Henschel was able to upgrade its various steam locomotives to a high-speed Streamliner type with a maximum speeds of up to by the addition of a removable shell over the old steam locomotive. In 1918, Henschel began the production of gearboxes at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MAN SE
MAN SE (abbreviation of ''Maschinenfabrik Augsburg-Nürnberg'', ) was a manufacturing and engineering company based in Munich, Germany. Its primary output was commercial vehicles and diesel engines through its MAN Truck & Bus and MAN Latin America divisions, and participation in the manufacturer Sinotruk. MAN SE was majority-owned by Traton, the heavy commercial vehicle subsidiary of automaker Volkswagen AG, until August 2021 when Traton completed a squeeze out of all remaining shareholders and formally merged MAN SE into Traton SE, meaning the former subsidiaries of MAN SE were now directly owned by Traton, and MAN SE ceased to exist. History Foundation MAN traces its origins back to 1758, when the "St. Antony" ironworks commenced operation in Oberhausen, as the first heavy-industry enterprise in the Ruhr region. In 1808, the three ironworks "St. Antony", "Gute Hoffnung" (English: "Good Hope"), and "Neue Essen" (English: "New Forges") merged, to form the Hüttengewerks ...
