Elefant Records Artists
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 the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Army Ordnance Training And Heritage Center
The United States Army Ordnance Training Support Facility (formerly known as the U.S. Army Ordnance Training and Heritage Center and U.S. Army Ordnance Museum) artifacts are used to train and educate logistic soldiers. It re-located to Fort Lee, outside Petersburg, Virginia.

VK 4501 (P)
The VK 45.01 (P), also informally known as Tiger (P) or Porsche Tiger, was a gasoline-electric drive heavy tank prototype designed by Porsche in Germany. Losing to its Henschel competitor on trials, it was not selected for mass production and the Henschel design was produced as the Tiger I. Most of the already produced chassis were rebuilt as Elefant tank destroyers. Development On 26 May 1941, Henschel and Porsche were asked to submit designs for a 45-ton heavy tank capable of mounting the high velocity 8.8 cm Kwk 36 L/56 gun which was derived from the German 88 mm Flak 37 antiaircraft gun. Both the Henschel and Porsche tanks were to be fitted with the same turret supplied by Krupp. The Porsche company worked on updating the VK 30.01 (P) medium tank, Porsche's medium tank prototype, and adapted parts used on it for the new tank. The new Porsche tank, designated the VK 45.01 (P) was to be powered by twin V-10 air cooled Porsche Type 101 gasoline engines which were mounted t ...

Casemate
A casemate is a fortified gun emplacement or armored structure from which artillery, guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to Ancient history, antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see #Antiquity: casemate wall, Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gearbox
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drive Shaft
A drive shaft, driveshaft, driving shaft, tailshaft (Australian English), propeller shaft (prop shaft), or Cardan shaft (after Girolamo Cardano) is a component for transmitting mechanical power (physics), power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion (mechanics), torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, while avoiding too much additional weight as that would in turn increase their inertia. To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a Rotating spline, splined joint or prismatic joint.

Petrol–electric Transmission
Petrol–electric transmission (UK English) or gasoline–electric transmission or gas–electric transmission (US English) is a transmission system for vehicles powered by petrol engines. Petrol–electric transmission was used for a variety of applications in road, rail, and marine transport, in the early 20th century. After World War I, it was largely superseded by diesel-electric transmission, a similar transmission system used for diesel engines; but petrol-electric has become popular again in modern hybrid electric vehicles. Petrol–electric transmission was used in certain niche markets in the early 20th century, such as in the petrol–electric railway locomotives produced in Britain for use on the War Department Light Railways during World War I or for privately owned Arad & Csanad United Railways. In France, the Crochat petrol–electric transmission system was used for standard gauge locomotives (up to 240 kW of electrical power). Description Petrol-electric ...

Nashorn
''Nashorn'' (, German for "rhinoceros"), initially known as ''Hornisse'' (German "hornet"), was a German ''Panzerjäger'' ("tank hunter") of World War II. It was developed as an interim solution in 1942 by equipping a light turretless chassis based on the Panzer III and Panzer IV tanks with the 88mm Pak 43 anti-tank gun. Though only lightly armoured and displaying a high profile, it could penetrate the front armour of any Allied tank at long range, and its relatively low cost and superior mobility to heavier vehicles ensured it remained in production until the war's end. Development After the first German experiences with the newer Soviet tanks like the T-34 medium tank or the Kliment Voroshilov heavy tank during Operation Barbarossa, the need for a ''Panzerjäger'' capable of destroying these more heavily armoured tanks became clear. In February 1942, the Alkett (''Altmärkische Kettenwerke GmbH'') arms firm of Berlin designed a tank destroyer using their recently deve ...

Marder III
''Marder'' III was the name for a series of World War II German tank destroyers. They mounted either the modified ex-Soviet 76.2 mm F-22 Model 1936 divisional field gun, or the German 7.5 cm PaK 40, in an open-topped fighting compartment on top of the chassis of the Czechoslovakian Panzer 38(t). They offered little protection to the crew, but added significant firepower compared to contemporary German tanks. They were in production from 1942 to 1944, and served on all fronts until the end of the war, along with the similar Marder II. The German word ''Marder'' means " marten" in English. History In the early stages of Operation Barbarossa, the Wehrmacht felt the need for a more mobile and more powerful anti-tank solution than the existing towed anti-tank guns, such as the '' 3.7 cm Pak 36'', or self-propelled tank destroyers, such as the ''Panzerjäger I'' (mounted with the 4.7 cm PaK (t)). This need became urgent in 1942, when anti-tank shells fired from said anti-tank guns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marder II
The ''Marder'' II ("marten" in English) was a German tank destroyer of World War II based on the Panzer II chassis. There were two versions, the first mounted a modified Soviet 7.62 cm gun firing German ammunition, while the other mounted the German 7.5 cm Pak 40 gun. Its high profile and thin open-topped armor provided minimal protection to the crew. Nevertheless, the Marder II (and similar Marder III) provided a great increase in firepower over contemporary German tanks during 1942 and into 1943. Only four Marder IIs remain today. History During the first days of Operation Barbarossa, the invasion of the Soviet Union, the Germans came unprepared to encounter Soviet T-34 medium tanks and KV heavy tanks. Although the ''Wehrmacht'' succeeded in most operations due to superior tactics, air support and supply, the lack of anti-tank weapons capable of successfully engaging these vehicles at range was becoming evident. An urgent need arose for a mobile and powerful enough anti- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panzerjäger
''Panzerjäger'' (German language, German "armour-hunters" or "tank-hunters", abbreviated to ''Pz.Jg.'' in German) was a branch of service of the Nazi Germany, German Wehrmacht during the World War II, Second World War. It was an Anti-tank warfare, anti-tank arm-of-service that operated Self-propelled artillery, self-propelled anti-tank artillery, also named ''Panzerjäger''. Soldiers assigned to tank hunting units wore ordinary Feldgrau, field-gray uniforms rather than the black of the Panzer troops, while ''Panzerjäger'' vehicle crews wore the Panzer jacket in field gray. Development From 1940, the ''Panzerjäger'' troops were equipped with vehicles produced by mounting an existing anti-tank gun complete with the gun shield on a tracked chassis to allow higher mobility. The development of ''Panzerjägers'' into the fully protected ''Jagdpanzer'' armored vehicle designs began before the war with the ''Sturmgeschütz''-designated armored Self-propelled artillery, artillery ve ...

Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...
