A7V
The Sturmpanzerwagen A7V was a heavy tank introduced by Germany in 1918 during World War I. One hundred chassis were ordered in early 1917, ten to be finished as fighting vehicles with armoured bodies, and the remainder as '' Überlandwagen'' cargo carriers. The number to be armoured was later increased to 20. They were used in action from March to October 1918, and were the only tanks produced by Germany in World War I to be used in combat, as well as being the first operational German tank. Although various German armoured vehicle proposals were shown a modest amount of support early in the war, enthusiasm among German high command was low and they were given little funding and attention. The sudden appearance of the British Mark series of tanks causing panic amongst the German infantry led this to be reconsidered however, and development on the German tank program began. History After the first British tanks appeared on the Western Front, in September 1916, the German War ...

Mephisto (tank)
Mephisto is a World War I German Empire, German tank, the only surviving example of an A7V. In April 1918, during Second Battle of Villers-Bretonneux, a German attack at Villers-Bretonneux on the Western Front (World War I), Western Front, it became stuck in a shell-hole and was abandoned by its crew. It was recovered by Allied troops about three months later and, after the war, taken to Australia as a trophy. Mephisto is housed at the Queensland Museum, in Brisbane, in the Anzac Legacy Gallery. It is not in running order. History Background The vehicle was issued to the army in late December 1917 or early January 1918, and was given vehicle number 506.

Überlandwagen
The Überlandwagen ("Over-land vehicle") was a tracked supply carrier built on the chassis of the German A7V ''Sturmpanzerwagen'' tank. When the A7V was first developed, the design committee made allowance for the chassis to be fitted with an alternative load carrying body. Description The ''Überlandwagen'' shared a common chassis with the A7V tank; both having suspension derived from the American Holt tractor and twin 100 hp Daimler engines centrally mounted. A driving position was sited on a platform above the engines, with dual sets of controls for driving in either direction to avoid the need to turn the vehicle. A canopy was fitted over the driving position, and wooden dropsides and ends were fitted at the front and rear of the vehicle. Some examples had rails added to support a tarpaulin over the load spaces. Towing hooks were fitted at both ends of the chassis. The vehicle had a top speed of and was manned by a driver and an assistant. Service A production run of ...

Mark I Tank
British heavy tanks were a series of related armoured fighting vehicles developed by the United Kingdom of Great Britain and Ireland, UK during the First World War. The Mark I was the world's first tank, a tracked, armed, and armoured vehicle, to enter combat. The name "tank" was initially a code name to maintain secrecy and disguise its true purpose. The tank was developed in 1915 to break the stalemate of trench warfare. It could survive the machine gun and small-arms fire in "no man's land", travel over difficult terrain, crush barbed wire, and cross trenches to assault fortified enemy positions with powerful armament. Tanks also carried supplies and troops. British heavy tanks are distinguished by a rhomboidal shape with a high climbing face of the track, designed to cross the wide and deep Trench warfare, trenches prevalent on the battlefields of the Western Front (World War I), Western Front. Due to the height necessary for this shape, an armed turret would have made the v ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Heavy Tank
A heavy tank is a tank classification produced from World War I to 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 I and Tiger II designs, or the Soviet Kliment Voroshilov tank, KV and IS tank family, IS designs. Design Heavy tanks feature very heavy vehicle armour, armor and weapons relative to lighter tanks. Many heavy tanks shared components with lighter tanks. For example, the US M103 (heavy tank), M103 heavy tank shared many components with the lighter Patton tank, including transmission and engine. As a result, they tend to be either underpowered and comparatively slow, or hav ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Western Front (World War I)
The Western Front was one of the main Theatre (warfare), theatres of war during World War I. Following the outbreak of war in August 1914, the Imperial German Army, German Army opened the Western Front by German invasion of Belgium (1914), invading Luxembourg and Belgium, then gaining military control of important industrial regions in Third Republic of France, France. The German advance was halted with the First Battle of the Marne, Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trench warfare, trenches, stretching from the North Sea to the Swiss frontier with France, the position of which changed little except during early 1917 and again in 1918. Between 1915 and 1917 there were several offensives along this Front (military), front. The attacks employed massive artillery bombardments and massed infantry advances. Entrenchments, machine gun emplacements, barbed wire, and artillery repeatedly inflicted severe casualties ...

Holt Tractor
The Holt tractors were a range of continuous track haulers built by the Holt Manufacturing Company of Stockton, California which were named after company founder Benjamin Holt. Between 1908 and 1913, twenty-seven of the first 100 Holt caterpillar track-type tractors were used on the Los Angeles Aqueduct project, which provided a good proving ground for these machines. Military use They were widely used by the British, French and American armies in the First World War for hauling heavy artillery including the BL 9.2-inch howitzer and the BL 8-inch howitzer. Around 2,000 Holt 75s along with 698 Holt 120s and 63 Holt 60s saw military use during the war. The French Schneider CA1 and Saint-Chamond and German A7V tanks were based on Holt tractors. Specification There were at least three models used for military purposes: the Holt 75, the Holt 120 and to a lesser extent the Holt 60. The Holt 75 was first produced in 1913. It used two tracks for steering. It had a maximum ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Power-to-weight Ratio
Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance to another. Power-to-weight ratio is equal to thrust per unit mass multiplied by the velocity of any vehicle. Power-to-weight ( ...

Armored Car (military)
A military armored (Commonwealth English, also spelled armoured) car is a wheeled armoured fighting vehicle, historically employed for reconnaissance, internal security, armed escort, and other subordinate battlefield tasks. With the gradual decline of mounted cavalry, armored cars were developed for carrying out duties formerly assigned to light cavalry. Following the invention of the tank, the armoured car remained popular due to its faster speed, comparatively simple maintenance and low production cost. It also found favor with several Colonial troops, colonial armies as a cheaper weapon for use in underdeveloped regions. During World War II, most armoured cars were engineered for reconnaissance and passive observation, while others were devoted to communications tasks. Some equipped with heavier armament could even substitute for tracked combat vehicles in favorable conditions—such as pursuit or flanking maneuvers during the North African campaign. Since World War II t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bundesarchiv Bild 146-1971-092-24, Westfront, Deutscher Sturmpanzer
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media (Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the ...
